Abstract:
Sponges interact with most other organisms in marine systems as competitors, symbionts, hosts of symbionts, consumers, and prey. Considerable creative energy has been required to study and describe the amazing variety of sponge interactions, as sponges can hide symbionts deep inside, rapidly regenerate wounds from grazers, carry on important associations with unculturable microscopic organisms, and otherwise foil attempts to determine how they are interacting with other organisms. This review of sponge interactions covers (i) competition among sponge species, and between sponges and other sessile organisms; (ii) predation on sponges by sponge specialists and by opportunistic sponge feeders, and aspects of predation such as the importance of nutritional quality, trade-offs between growth and defense against predators, biogeographic patterns in predation, and the advantages of various techniques for studying predation; and (iii) symbiotic associations of sponges with a variety of organisms representing all types of life, and with results ranging from parasitism and disease to mutual benefit. A hint that some generalizations about ecological interactions of sponges may be possible is just becoming evident, as accumulating data appear to show taxonomic and geographic patterns; however, it is also clear that surprises will continue to emerge from every probing new study.

Abstract:
Bacteria are found to be highly associated with various marine organisms, such as sponges. Sponges are known as the product of bioactive compounds. However, some of the compounds produced by sponges are obtained by the simbion-bacteria. Therefore this situation enables sponges simbion bacteria to play a major role in producing bioactive compounds that have been isolated from the sponge. The purpose of this study is to isolate and determine the characteristics of morphology of spongy simbion bacteria resembling Cribochalina sp, which was taken from Malalayang waters, North Sulawesi. Sponge simbion bacteria grow on NB media. Initially, a free-breeding colony was being done before bacteria were accrued in the NA media by 2% sponge broth (patent SID201906301) by means of Strike Plate methods. Based on to this study we had isolate five spongy simbion bacteria that resembling the Cribochalina sp. All five of these isolations have different characteristics of morphology in terms of color, shape, size, and elevation. Keywords : bacteria, isolation, simbionts, sponges

Abstract:
ABSTRACT Symbiotic microbes play a variety of fundamental roles in the health and habitat ranges of their hosts. While prokaryotes in marine sponges have been broadly characterized, the diversity of sponge-inhabiting fungi has barely been explored using molecular approaches. Fungi are an important component of many marine and terrestrial ecosystems, and they may be an ecologically significant group in sponge-microbe interactions. This study tested the feasibility of using existing fungal primers for molecular analysis of sponge-associated fungal communities. None of the eight selected primer pairs yielded satisfactory results in fungal rRNA gene or internal transcribed spacer (ITS) clone library constructions. However, 3 of 10 denaturing gradient gel electrophoresis (DGGE) primer sets, which were designed to preferentially amplify fungal rRNA gene or ITS regions from terrestrial environmental samples, were successfully amplified from fungal targets in marine sponges. DGGE analysis indicated that fungal communities differ among different sponge species (Suberites zeteki and Mycale armata) and also vary between sponges and seawater. Sequence analysis of DGGE bands identified 23 and 21 fungal species from each of the two sponge species S. zeteki and M. armata, respectively. These species were representatives of 11 taxonomic orders and belonged to the phyla of Ascomycota (seven orders) and Basidiomycota (four orders). Five of these taxonomic orders (Malasseziales, Corticiales, Polyporales, Agaricales, and Dothideomycetes et Chaetothyriomcetes incertae sedis) have now been identified for the first time in marine sponges. Seven and six fungal species from S. zeteki and M. armata, respectively, are potentially new species because of their low sequence identity (≤98%) with their references in GenBank. Phylogenetic analysis indicated sponge-derived sequences were clustered into “marine fungus clades” with those from other marine habitats. This is the first report of molecular analysis of fungal communities in marine sponges, adding depth and dimension to our understanding of sponge-associated microbial communities.

Abstract:
Marine sponge holobionts, defined as filter-feeding sponge hosts together with their associated microbiomes, are prolific sources of natural products. The inventory of natural products that have been isolated from marine sponges is extensive. Here, using untargeted mass spectrometry, we demonstrate that sponges harbor a far greater diversity of low-abundance natural products that have evaded discovery. While these low-abundance natural products may not be feasible to isolate, insights into their chemical structures can be gleaned by careful curation of mass fragmentation spectra. Sponges are also some of the most complex, multi-organismal holobiont communities in the oceans. We overlay sponge metabolomes with their microbiome structures and detailed metagenomic characterization to discover candidate gene clusters that encode production of sponge-derived natural products. The multi-omic profiling strategy for sponges that we describe here enables quantitative comparison of sponge metabolomes and microbiomes to address, among other questions, the ecological relevance of sponge natural products and for the phylochemical assignment of previously undescribed sponge identities.

Abstract:
Although the diversity of life in the terrestrial environment is exceptional, the greatest biodiversity is in the marine environment. Among the marine organisms, the sponges (Porifera) are the most prolific sources of bioactive secondary metabolites. The Philippines, with its long coastal lines, has drawn on its marine capital only to a small extent. Only a few marine organisms (ascidians, sponges, other marine invertebrates and their associated microorganisms) collected from various parts of the Philippines have been documented and investigated in terms of their potential as source of bioactive secondary metabolites, particularly anticancer compounds. Thirty-seven sponges from the coasts off Mindanao, Philippines were collected, identifies and extracted to give a total of seventy-four polar and nonpolar extracts. The corresponding sponge extracts were screened for the sponge extracts were investigated for cytotoxicity towards colon cell lines (HCT116) using the the tetrazolium dye (3-(4,5-Dimethylthiazol-2-yl)- 2,5- diphenyltetrazolium bromide) [MTTmethod. The results indicated fifteen (15) sponge extracts to be active at 100- microgram/mL concentration among which seven (7) were still active at 10 microgram/mL while two (2) still exhibited activity at 1 microgram/mL. Further investigation of the active sponge extracts is currently in progress

Abstract:
Many species of marine sponges on tropical reefs host abundant and diverse symbiont communities capable of varied metabolic pathways. While such communities may confer a nutritional benefit to some hosts (termed High Microbial Abundance (HMA) sponges), other sympatric species host only sparse symbiont communities (termed Low Microbial Abundance (LMA) sponges) and obtain a majority of their C and N from local sources. Sponge communities are widespread across large latitudinal gradients, however, and recent evidence suggests that these symbioses may also extend beyond the tropics. We investigated the role that symbionts play in the ecology of sponges from the temperate, hard-bottom reefs of Gray's Reef National Marine Sanctuary by calculating the niche size (as standard ellipse area (SEAc)) and assessing the relative placement of five HMA and four LMA sponge species within bivariate (δ13C and δ15N) isotopic space. Although photosymbiont abundance was low across most of these species, sponges were widespread across isotopic niche space, implying that microbial metabolism confers an ecological benefit to temperate sponges by expanding host metabolic capability. To examine how these associations vary across a latitudinal gradient, we also compared the relative placement of temperate and tropical conspecifics within isotopic space. Surprisingly, shifts in sponge δ13C and δ15N values between these regions suggest a reduced reliance on symbiont-derived nutrients in temperate sponges compared with their tropical conspecifics. Despite this, symbiotic sponges in temperate systems likely have a competitive advantage, allowing them to grow and compete for space within these habitats.

Abstract:
Marine sponges are the most prolific marine sources for discovery of novel bioactive compounds. Sponge secondary metabolites are sought-after for their potential in pharmaceutical applications, and in the past, they were also used as taxonomic markers alongside the difficult and homoplasy-prone sponge morphology for species delineation (chemotaxonomy). The understanding of phylogenetic distribution and distinctiveness of metabolites to sponge lineages is pivotal to reveal pathways and evolution of compound production in sponges. This benefits the discovery rate and yield of bioprospecting for novel marine natural products by identifying lineages with high potential of being new sources of valuable sponge compounds. In this review, we summarize the current biochemical data on sponges and compare the metabolite distribution against a sponge phylogeny. We assess compound specificity to lineages, potential convergences, and suitability as diagnostic phylogenetic markers. Our study finds compound distribution corroborating current (molecular) phylogenetic hypotheses, which include yet unaccepted polyphyly of several demosponge orders and families. Likewise, several compounds and compound groups display a high degree of lineage specificity, which suggests homologous biosynthetic pathways among their taxa, which identifies yet unstudied species of this lineage as promising bioprospecting targets.

Abstract:
Using culture - independent technique, hypervariable V4 region of 16S rDNA library sequencing by MiSEq, the baterial communities of three host sponges Rhabdastrella sp. DN, Spheciospongia sp. QT and Clathria sp. NT from Mien Trung sea were characterized. The phylogenetic analysis showed that bacterial community structures of the three investigated sponges similar to each other regarding 10 common phyla, although abundance of these phyla was different for each sponge. Phylum Thaumarchaeota was rich component for three sponges, especially in NT sponge (31.89%). In this sponge, 3 phyla Planctomycetes, Verrucomicrobia and Firmicutes were undetected in other 2 sponge samples. Phyla Cyanobacteria was observed only in DN sponge. The obtained amplicons were assigned in different taxonomic levels (class, order, family and genus) based on Silva database. At class level, Gammaproteobacteria was abundant in three sponges; and Caldilineae, Marine-group I were dominant in DN; mealwile, in QT other dominant classes were Marine-group I and Betaproteobacteria. For NT, they were Cytophaga and Deferribacteres. In general, all three sponges harbored abundant and genetically diverse microbial associated consortia and they shared several common bacterial operational taxonomic units, although with different abundance.

Abstract:
A chemical study of the marine petrosid sponge Xestospongia vanilla has led to the isolation of nine new isoprene derived secondary metabolites. Their proposed structures were elucidated by a combination of spectroscopic analysis and chemical degradation and interconversions. Xestodiol (94), a C₁₈ apocarotenoid, appears to be a degradation product of the abundant marine carotenoid fucoxanthin (103). The xestovanins (98-102) are triterpene glycosides; their isolation represents the second reported occurrence of this type of compound from sponges. Their triterpene carbon skeletons are unique, and are either monocyclic (secoxestovanane skeleton) or bicyclic (xestovanane skeleton). All the xestovanins contain the same disaccharide fragment composed of L-rhamnose alpha linked to the 4 position of D-fucose. The fucose residue is beta linked to the same position on the aglycone in all isolated xestovanins. Xestovanin D (102) contains an extra L-rhamnose residue attached to a different position on the aglycone. Xestovanin A (98) was found to be an inhibitor of fungal growth, while xestovanin C (101) inhibited the growth of bacteria. A series of three smaller apparently related terpenes was also isolated. Xestenone (95) and secoxestenone (97) both contained new C₁₉ carbon skeletons. Secoxestenone (97), a monocyclic compound, could be converted into the bicyclic xestenone (95) by an intramolecular aldol condensation. The C₂₀ xestolide (96), with a similar structure to both xestenone and secoxestenone, had an unique carbon skeleton that could not be derived readily from an unrearranged diterpene skeleton. It is suggested that these three smaller terpenes (95-97) are degraded triterpenes, derived from a secoxestovanane carbon skeleton. The secondary metabolite chemistry of the petrosid sponges is reviewed, and an overview of triterpenes of marine origin is presented.

Abstract:
The giant barrel sponge, Xestospongia muta is an iconic and essential species of the coral reefs in South Florida. The sponge has primary roles providing ecosystem services and creating unique habitats for diverse microbial communities. On April 27, 2012 an outbreak of Sponge Orange Band Disease (SOB) was detected off the coast of South Florida. The disease begins with sponge bleaching, followed by mesohyl or “mesohyl” necrosis and often total mesohyl disintegration. Sampling from two diseased populations at Boynton Beach and Fort Lauderdale, FL took place on May 11th and May 29th, 2012. Each of the nine diseased sponges from Boynton Beach and the five diseased sponges from Fort Lauderdale had three separate mesophyl samples collected to examine the effects of disease progression on the microbial community. These included healthy mesohyl from a diseased sponge (HoD), the boundary layer which captured the advancing line of diseased mesohyl (BL) and diseased mesohyl from a diseased sponge (D). Mesohyl from three sponges with no visible signs of SOB disease were also collected from each sampling location to use for healthy controls (HC). Sequencing of the V4 region of the 16S rRNA gene was performed on all of these samples via the “454” pyrosequencing on a Titanium GS FLX platform. The microbial communities associated with the diseased samples revealed a microbiome shift that followed the progression of Sponge Orange Band Disease (SOB) and was dominated by Bacteroidetes, Protebacteria and Chloroflexi. No singular or group of microbes were solely found within the infected mesohyl of Xestospongia muta from both sampling site populations; therefore there is no unequivocal candidate as a definite microbial causative SOB agent. But there were bacteria associated with disease progression that included Armatimonadetes, Caldithrix, Chlorobi, Fibrobacteres, Fusobacteria, GN02, KSB3, OP1, OP2, OP8, Planctomycetes, SR1, TM6, Tenericutes, Verrucomicrobia, WPS-2 and ZB3. Verrucomicrobia and Plantomycetes increased significantly within the D and the BL populations, which was consistent within all the diseased sponges. This study provides a deep sequencing profile of microbial communities within Xestospongia muta affected with SOB Disease and provides a new insight into the sponge healthy microbiome.

Abstract:
Bromotyrosine-derived secondary metabolites from marine sponges of the order Verongida provide unique diversity in chemical structure and a wide range of biological activities. With a decline in the number of novel antibiotic scaffolds which are emerging and the on-going search for more effective antibacterial and anticancer drugs, these brominated metabolites are attractive candidates for further total synthesis and biological evaluation. An Efficient total synthesis of bromotyrosine alkaloids purpurealdin E (92), aplyzanzine A (122), suberedamine A (123) and B (124), iso-Anomoian A (121a) and aplysamine-2 (104) were achieved through the carbodiimide coupling of appropriate tyrosine/tyramine units in excellent yields. Their structures have been confirmed through direct comparison with spectroscopic data of isolated natural products. The key step was the one-pot Bocdeprotection, dimethylation and hydrolysis of desired intermediate, which was achieved in 88% yield. A new synthetic route was developed for the preparation of diverse analogues for biological assessment. This route utilized cheap and commercially available starting materials, and allowed access to various analogues inaccessible via currently reported methods. By utilising this route, the total syntheses of 5- bromoverongamine (207), 20-N-methylpu rpuramine E (208) , psammaplin A (150), psammaplin C (156), spermatinamine (50) and tokaradine A (209) were successfully carried out and are reported herein. These new syntheses of spermatinamine and psammaplin A are more efficient than previously reported sequences. In addition, we explored a method for the selective removal of benzyl protecting groups in the presence of both oxime and disulphide moieties. Aplyzanzine A (122) was found to be the most active product against a Grampositive bacterial and fungal screen demonstrating MIC values 2-4 times lower than the other compounds. All compounds, except purpurealdin E and psammaplin C, exhibit modest inhibition against M. bovis BCG and M. tuberculosis H37Rv. 20-N-methylpurpuramine-E (208) was most active with an MIC (5 μg/mL) towards M. bovis BCG. iso-Anomoian A (1 21a) and suberedamine B (124) showed antitumor activity in the NCI-DTP60 cell line screen at single micromolar concentrations, with iso-anomoian A (121 a) inhibiting 53 cell lines. These molecules present novel scaffolds for further optimization.

Abstract:
This thesis described the chemical investigations of natural products from Australian marine sponge-derived fungi. Sponge samples were collected from the Great Barrier Reef, Queensland, Australia, by Queensland Museum. The thesis is divided into eight chapters and can be devided into two major parts. The first three chapters comprised the first part of the thesis: Chapter 1 outlined the research background, literature review of marine fungal secondary metabolites; Chapter 2 introduced fungal culture and storage background knowledge, and the list of isolated marine fungal strains. Chapter 3 introduced the background of the thrombin inhibition assay and assay results. The second part (Chapter 4 to 7) of this thesis is focused on chemical isolation and structure elucidation of secondary metabolites from isolated fungal strains, mostly active strains against thrombin. An unidentified fungal strain, FS-G315858 (T)-Y, isolated from the frozen sponge sample Dysidea sp.1400 produced five peptide compounds (chapter 4, 16-20). Compound 16 is a polypeptide which features the same relative configuration with a known compound unguisine A, and compounds 17-20 are diketopiperazines. Active fungal strains FS-G315695 (T)-Y and FDPS-61732-YB were isolated from different sponge samples. However, they were identified to be the identical fungal strain Eurotium rubrum; the chemical isolation of FS-G315695 (T)-Y from its mycelia EtOAc extract resulted in three compounds (chapter 5, 17-19). Compounds 18 and 19 were identified to be flavoglaucin and iso-dihydroauroglaucin. Compound 17 was identified to have the same relative configuration with a known compound neo-echinulin A. The chemical isolation of FDPS-61732-YB from its broth EtOAc extract resulted in several diketopiperazines (chapter 5, 27-29). Another active fungal strain FS-G315695 (T)-WY was identified as Aspergillus ochraceous, the chemical isolation of its mycelia EtOAc extract resulted in one benzodiazepine compound (chapter 6, 18), together with two fatty acids (chapter 6, 16-17). The structure of compound 18 was elucidated and identified to have same relative configuration with the known compound circumdatin E. Media comparison for active fungal strain FS-G315695 (T)-Y was conducted and this work resulted in producing several neo-echinulin analogues (chapter 7, 1-3). The isolation and structure elucidation of these compounds were reported in chapter 7.

Full text
Abstract:
Onnamide F is a recently isolated natural product from the southern Australian marine sponge, Trachycladus laevispirulifer, that has shown significant antifungal and nematocidal activity. Onnamide F contains a tetrahydropyran substructure, known as pederic acid, and an amide bond linkage to a second tetrahydropyran. To date no total synthesis of onnamide F has been reported. A range of tetrahydropyrans with structural similarities to pederic acid were synthesised using a new Lewis acid mediated cyclisation reaction. Additionally, a diastereoselective route to tetrahydropyrans containing the exo-methylene functionality at C4 has been developed. A useful new route to the pederic acid precursor pederamide has been established. The tetrahydropyran skeleton was formed by a new Lewis acid mediated cyclisation reaction between 3,4-Dimethylpent-4-en-2-ol and trans-cinnamaldehyde, promoted by benzyltriethylammonium aluminium chloride. Further transformations gave us the opportunity to establish the correct oxidation level at the anomeric centre. Methyl ether formation followed by removal of the acetate group furnished a secondary alcohol which could be resolved via formation of the (+)-acetylmandelate ester. The enantiomerically pure tetrahydropyran was subjected to a Dess-Martin oxidation. Treatment with TMSCN followed by borax induced hydrolysis gave pederamide and its diastereoisomer.

Abstract:
This project focuses on the use of sponge genetic transcripts in the form of expressed sequence tags (ESTs) readily available in Genbank to search for novel genes using bioinformatics analysis tools. Marine sponge species are known to house a diversity of marine microbes and are known as the ‘living fossils’ of the animal kingdom because of the large number of ancient genes they house. Genomic mining can be a useful tool in discovering these orthologous genes. This study utilized the techniques of genomic mining of 11 previously described sponge species transcripts. The results of this study provide a better understanding of the genomic structure of the organisms studied by creating a more detailed genetic map and examining a specific environmental snapshot of the genes in each sponge. Novel methods for dissecting beneficial information from large scale data sets available in genomic libraries utilizing bioinformatics search tool MGRAST were examined. The results of this study indicate that sponges house numerous genes that are likely to be evolutionary predecessors of genes in higher eukaryotes. Support was also given to the notion that microbial communities play a role in metabolic pathways of sponges.

Abstract:
The Marine sponge Cinachyrella sp used in this study are commonly found in offshore South Florida and Caribbean waters and appeared to be resilient in closed system aquaculture. Marine sponges host diverse bacterial symbionts that are distinct compared to bacteria found in ambient seawater, however the roles of a large fraction of the bacterial community in marine sponges are unknown. Comparison of symbiotic to aposymbiotic (bacteria-free) sponges could provide information about interactions (metabolic and physiologic) between the bacteria and sponge. In this study, a single Cinachyrella kuekenthali individual was subsectioned into explants (N=240) in order to provide identical bacterial communities to perform comparative studies. Presence of photosymbionts was also analyzed by characterizing bacterial communities from varying light and dark conditions. Tools for characterization included transmission electron microscopy (TEM) and 16S rRNA sequence analysis obtained from Illumina Miseq. High throughput DNA sequencing revealed bacterial taxa belonging to phyla Thaumarchaeota, Chloroflexi, Nitrospira, Acidobacteria and Verrucomicrobia persist in the explants. This study also demonstrated that antibiotics (Ampicillin, Tetracycline, Penicillin-Streptomycin and combination of all) can alter the bacterial community in the marine sponge C. kuekenthali explants in vitro. Bacterial communities of explants treated with different antibiotics were statistically (Unifrac and Bray-Curtis analysis) different from controls (p-value < 0.001, R2=41%). Penicillin-streptomycin and cocktail of antibiotics treatment contributed to the highest difference in the bacterial communities. Also, bacterial communities of explants at difference time points treated with corresponding antibiotics were also statistically significant (p-value<0.05, R2=15%). TEM observations of denatured nucleic acid and osmotic lysis of bacteria, due to the effect of antibiotics were observed, creating a LMA mesohyl. However light versus dark conditions did not produce any statistically significant difference in beta diversity between bacterial communities. These interdisciplinary results indicate that while individual bacterial symbiont taxa may persist after community disruption, significant changes in the overall composition of the bacterial symbiont population can be created

Abstract:
AbstractSponges (Porifera), basal nonbilaterian metazoans, are well known for their high regenerative capacities ranging from reparation of a lost body wall to whole-body regeneration from a small piece of tissues or even from dissociated cells. Sponges from different clades utilize different cell sources and various morphological processes to complete the regeneration. This variety makes these animals promising models for studying the evolution of regeneration in Metazoa. However, there are few publications concerning the regenerative mechanisms in sponges. This could be partially explained by the delicacy of sponge tissues, which requires modifying and fine adjusting of common research protocols. The current chapter describes various methods for studying regeneration processes in the marine calcareous sponge, Leucosolenia. Provided protocols span all significant research steps: from sponge collection and surgical operations to various types of microscopy and immunohistochemical studies.

Abstract:
Industrial development releases plenty of oil/dyes wastes to water making unsafe the environment to live in. This project aims to solve the problems associated with environmental pollution and discharge of industrial effluents to water bodies. This is very important in the global scenario as water is the basis of life. The problem of leaking oil and dyes in water bodies is one of the biggest problems that cause instability in the ecosystem since, it has a negative impact on marine creatures that live in these water bodies. In addition, this damage is transmitted to humans in an indirect way. The current project aims to develop ZnO/PVDF composite nanofibers using electrospun technique. The fabricated nanofibers were analyzed mainly for their morphology by using scanning electron microscope, X-Ray diffraction, mechanical tensile strength, UV light spectroscope and oil separation experiments was mainly targeted for the proposed research and photocatalytic performance. Using these nanoparticles oil absorption was done for the water contaminated with oil and dye. The novelty of this particular proposal is defined by the nontoxic material fabrication method in the form of membrane, the fabricated membrane can be used for both absorbing oil & separating dyes from water. We have successfully synthesized the flower-like ZnO architectures by hydrothermal method, developing oil and dye absorbing membrane using electrospinning techniques. It can absorb oil and dyes from water wastes, can be reused many times. The observed results suggest that the fabricated flexible electrospun nanofibers are suitable for the wastewater treatment. Our future recommendations to test different types of dyes not mentioned in this research involve, mixing two dyes together and check testing by the fabricated membrane, testing mixture of both oil and dye wastes together and develope the membrane to be as a sponge, which can hold the oil then collecting this oil and reusing it again.

Abstract:
A short but productive cruise aboard RV William Kennedy tested various new field equipment near Halifax (port of departure and return) but also in areas that could also benefit science understanding. The GSC-A Gavia Autonomous Underwater Vehicle equipped with bathymetric, sidescan and sub-bottom profiler was successfully deployed for the first time on Scotian Shelf science targets. It surveyed three small areas: two across known benthic sponge, Vazella (Russian Hat) within a DFO-directed trawling closure area on the SE flank of Sambro Bank, bordering Emerald Basin, and one across known pockmarks, eroded cone-shaped depression in soft mud due to fluid efflux. The sponge study sites (~ 150 170 m water depth) were known to lie in an area of till (subglacial diamict) exposure at the seabed. The AUV data identified gravel and cobble-rich seabed, registering individual clasts at 35 cm gridded resolution. A subtle variation in seabed texture is recognized in sidescan images, from cobble-rich on ridge crests and flanks, to limited mud-rich sediment in intervening troughs. Correlation between seabed topography and texture with the (previously collected) Vazella distribution along two transects is not straightforward. However there may be a preference for the sponge in the depressions, some of which have a thin but possibly ephemeral sediment cover. Both sponge study sites depict a hereto unknown morphology, carved in glacial deposits, consisting of a series of discontinuous ridges interpreted to be generated by erosion in multiple, continuous, meandering and cross-cutting channels. The morphology is identical to glacial Nye, or mp;lt;"N-mp;lt;"channels, cut by sub-glacial meltwater. However their scale (10 to 100 times mp;lt;"typicalmp;gt;" N-channels) and the unique eroded medium, (till rather than bedrock), presents a rare or unknown size and medium and suggests a continuum in sub-glacial meltwater channels between much larger tunnel valleys, common to the eastward, and the bedrock forms. A comparison is made with coastal Nova Scotia forms in bedrock. The Emerald Basin AUV site, targeting pockmarks was in ~260 to 270 m water depth and imaged eight large and one small pockmark. The main aim was to investigate possible recent or continuous fluid flux activity in light of ocean acidification or greenhouse gas contribution; most accounts to date suggested inactivity. While a lack of common attributes marking activity is confirmed, creep or rotational flank failure is recognized, as is a depletion of buried diffuse methane immediately below the seabed features. Discovery of a second, buried, pockmark horizon, with smaller but more numerous erosive cones and no spatial correlation to the buried diffuse gas or the seabed pockmarks, indicates a paleo-event of fluid or gas efflux; general timing and possible mechanisms are suggested. The basinal survey also registered numerous otter board trawl marks cutting the surficial mud from past fishing activity. The AUV data present a unique dataset for follow-up quantification of the disturbance. Recent realization that this may play a significant role in ocean acidification on a global scale can benefit from such disturbance quantification. The new pole-mounted sub-bottom profiler collected high quality data, enabling correlation of recently recognized till ridges exposed at the seabed as they become buried across the flank and base of the basin. These, along with the Nye channels, will help reconstruct glacial behavior and flow patterns which to date are only vaguely documented. Several cores provide the potential for stratigraphic dating of key horizons and will augment Holocene environmental history investigations by a Dalhousie University student. In summary, several unique features have been identified, providing sufficient field data for further compilation, analysis and follow-up publications.

Abstract:
Grand Canyon-Parashant National Monument (PARA) in northwestern Arizona has significant paleontological resources, which are recognized in the establishing presidential proclamation. Because of the challenges of working in this remote area, there has been little documentation of these resources over the years. PARA also has an unusual management situation which complicates resource management. The majority of PARA is administered by the Bureau of Land Management (BLM; this land is described here as PARA-BLM), while about 20% of the monument is administered by the National Park Service (NPS; this land is described here as PARA-NPS) in conjunction with Lake Mead National Recreation Area (LAKE). Parcels of state and private land are scattered throughout the monument. Reports of fossils within what is now PARA go back to at least 1914. Geologic and paleontologic reports have been sporadic over the past century. Much of what was known of the paleontology before the 2020 field inventory was documented by geologists focused on nearby Grand Canyon National Park (GRCA) and LAKE, or by students working on graduate projects; in either case, paleontology was a secondary topic of interest. The historical record of fossil discoveries in PARA is dominated by Edwin McKee, who reported fossils from localities in PARA-NPS and PARA-BLM as part of larger regional projects published from the 1930s to the 1980s. The U.S. Geological Survey (USGS) has mapped the geology of PARA in a series of publications since the early 1980s. Unpublished reports by researchers from regional institutions have documented paleontological resources in Quaternary caves and rock shelters. From September to December 2020, a field inventory was conducted to better understand the scope and distribution of paleontological resources at PARA. Thirty-eight localities distributed across the monument and throughout its numerous geologic units were documented extensively, including more than 420 GPS points and 1,300 photos, and a small number of fossil specimens were collected and catalogued under 38 numbers. In addition, interviews were conducted with staff to document the status of paleontology at PARA, and potential directions for future management, research, protection, and interpretation. In geologic terms, PARA is located on the boundary of the Colorado Plateau and the Basin and Range provinces. Before the uplift of the Colorado Plateau near the end of the Cretaceous 66 million years ago, this area was much lower in elevation and subject to flooding by shallow continental seas. This led to prolonged episodes of marine deposition as well as complex stratigraphic intervals of alternating terrestrial and marine strata. Most of the rock formations that are exposed in the monument belong to the Paleozoic part of the Grand Canyon section, deposited between approximately 510 and 270 million years ago in mostly shallow marine settings. These rocks have abundant fossils of marine invertebrates such as sponges, corals, bryozoans, brachiopods, bivalves, gastropods, crinoids, and echinoids. The Cambrian–Devonian portion of the Grand Canyon Paleozoic section is represented in only a few areas of PARA. The bulk of the Paleozoic rocks at PARA are Mississippian to Permian in age, approximately 360 to 270 million years old, and belong to the Redwall Limestone through the Kaibab Formation. While the Grand Canyon section has only small remnants of younger Mesozoic rocks, several Mesozoic formations are exposed within PARA, mostly ranging in age from the Early Triassic to the Early Jurassic (approximately 252 to 175 million years ago), as well as some middle Cretaceous rocks deposited approximately 100 million years ago. Mesozoic fossils in PARA include marine fossils in the Moenkopi Formation and petrified wood and invertebrate trace fossils in the Chinle Formation and undivided Moenave and Kayenta Formations.
