Resumen
Depuis maintenant près d’un siècle, des robots sous-marins ont été développés afin de réaliser des tâches spécifiques aux besoins des grands acteurs historiques du domaine (militaires, pétroliers, câbliers ou explorateurs benthiques) sans vraiment se soucier de la polyvalence et de la modularité de la plateforme. L’objectif de cette thèse est d’avoir une réflexion sur une solution technologique et scientifique avec comme domaine applicatif l’environnement faible fond ou confiné. Il s’agit en d’autres termes de concevoir un robot sous-marin que l’on peut faire évoluer aisément tant sur le plan mécanique, électronique qu’informatique. Cet objectif impose de proprement conceptualiser cette « polyvalence » en s’attachant à apporter de l’abstraction dans l’architecture de contrôle que se soit au niveau de l’automatique avec l’expression de la polyvalence liée à l’étage d’actionnement ou de l’informatique avec une architecture basée services, pouvant être composés, afin de répondre à la diversité des besoins applicatifs. L’ensemble de ces travaux a pour point de départ le robot Jack mis au point par l’entreprise Ciscrea, partenaire industriel, qui apporte un aspect économique à la nécessité de développer une solution polyvalente pouvant être décliné en une gamme de produits. Ce manuscrit traite de la conception, la réalisation et l’expérimentation de ce vecteur que ce soit en piscine où en environnement réel
Since almost a century, underwater robots have been developed in order to respond to the specific needs of historical actors of the domain (military, hydrocarbons exploitation, underwater cabling or benthic exploration), without addressing specifically the question of versatility or modularity of the underwater platform. This thesis aims to address these questions on a technological solution dedicated to shallow water or confined environment. In other words, the objective is to realise an underwater system, able to evolve on the mechanical, electronical or software aspects. This requires to properly conceptualise this « versatility » with an abstraction of the control architecture, on the actuation aspect, with the expression of the versatility linked to the actuation systems, or on the software architecture level, with a Service-Oriented-Architecture (SOA) approach, in order to tackle the diversity of the application requirements. This study is based on the Jack system, developed by the Ciscrea Company, which is the industrial partner of this project, and brings the economical aspect as a central requirement. This underlines another view of the versatility question, the development of a range of product for the Ciscrea Company.This thesis proposes the conception, realisation and experimentation of such a versatile underwater system, with test-tank and field validation

Resumen
Expansion in the number and extent of marine protected areas (MPAs) has been dramatic during the past century, but coverage remains limited and there are concerns that many MPAs are failing to meet their objectives. After updating the global database of MPAs maintained by the Sea Around Us, new estimates of global marine protected area were calculated and revealed a degree of progress towards protecting at least 10% of the global ocean by 2020. It is estimated that more than 6,000 MPAs covering 3.27% of the world’s oceans (∼11.9 million km²) have been designated to date. The protection these MPAs offer is generally weak with about one-fifth (∼2.2 million km²) of their combined area designated as no-take (i.e., where fishing and other extractive activities are prohibited). Additional large tracts of ocean will need to be protected to reach the 10% target, and hypothetical scenarios for such expansion were investigated. To improve understanding of the likely conservation effectiveness of MPAs, trends in their management effectiveness were explored. Results from a self-administered survey questionnaire, distributed to managers and other experts associated with a random sample of MPAs from around the world, revealed a wide range of MPA management effectiveness across different socioeconomic contexts. The results were intended to inform a model of MPA management effectiveness based on socioeconomic, governance and other contextual variables, but no clear relationships between contextual variables and MPA management effectiveness were identified. Overall, the survey findings confirmed results of other studies: while some MPAs are well supported with funding, staff and equipment, others lack even basic management elements. Additional research is essential to understanding the issues preventing MPAs from meeting their objectives, including effectively contributing to biodiversity conservation.

Texto completo
Resumen
Pseudo-nitzschia multistriata is a toxic marine planktonic diatom that blooms regularly in the Mediterranean Sea. The species has a heterothallic mode of reproduction with two distinct mating types. This thesis aimed at exploring the molecular underpinnings of different stages of the sexual reproduction phase in Pseudo-nitzschia multistriata using genomics and transcriptomics approaches. A comparative transcriptomics approach was used to explore the molecular mechanisms involved in the early stages of sexual reproduction in which the opposite mating type strains engage in complex chemical communication and subsequent intracellular signaling. The present thesis identified a number of MT specific genes that are differentially regulated during sexual reproduction. The majority of these MT specific genes could not be annotated using homology based methods, suggesting that they have unique roles in this species. Further, substantial differences between the two mating types were observed in terms of metabolic processes employed during sex. Interestingly, a cell cycle arrest, a phenomenon extensively studied in yeasts, at the onset of the sexual phase was observed in Pseudonitzschia multistriata. Moreover, the genome of Pseudo-nitzschia multistriata along with other four diatom genomes was searched to look for the genes involved in meiosis. Although the majority of meiosis related genes could be identified, a few meiosis specific genes seem to be absent in diatoms, representing a case of lineage specific independent loss, observed in other sexually reproducing species. Lastly, genetic modification methods such as biolistic transformation and chemical mutagenesis were established for gene function studies in this species and the biolistic transformation is already being used to decipher the function of selected sex specific genes identified from RNA-seq experiments.

Resumen
Idiopathic blindness is an environmental disease observed in the American lobster, Homarus americanus H. Milne Edwards, 1837. The only diagnostic assay for idiopathic blindness has been the histological assessment of the eye, which is a time consuming, invasive, and a delicate procedure. I investigated several tools, including the otolaryngoscope and enhanced counterstaining using Bouin’s fixative as alternative, rapid methods for the detection of idiopathic blindness in lobsters. I applied these new diagnostic techniques to toxicology studies to explore a possible lead on the etiology of this condition. Divalent manganese is a well-established neurotoxin released from sediments under hypoxic conditions. Previous studies have shown that the metal exhibits a high affinity for nervous tissue in the confamilial Norway lobster, Nephrops norvegicus. With this prior knowledge, an acute exposure study was designed to expose H. americanus to 0, 20, 80, 150, and 300 mg Mn L-1 (ppm) for 96 hrs. The objectives were to explore disparities in Mn accumulation within various tissues, and determine a non-lethal or sublethal exposure concentration to be used in a chronic exposure study. A positive correlation between Mn accumulation and exposure concentration was observed in all tissue types. The metal was shown to have a consistent pattern of affinity with respect to internal tissues: Hemolymph > optic nerve > brain > hepatopancreas = muscle. A chronic exposure study was designed to investigate the potential link between Mn exposure and idiopathic blindness. That study consisted of a seven week exposure to 150 ppm Mn, with regular assessment of the eyes of the animals using the otolaryngoscope, histological analysis as an endpoint, and comparisons of Mn in the tissues. Animals that molted in the chronic exposure study were found to have very high levels of Mn in their exoskeletons compared to those that had not molted. There was no apparent relationship between Mn exposure and blindness. Alternative theories concerning the etiology of this disease should be considered in future studies.

Resumen
This thesis covers a wide range of research on marine natural products with a focus on their role in drug discovery. Chapter 1 starts with a general introduction to marine natural product chemistry, describing current trends and problems. It gives an insight into the importance of the discovery of new antibiotics in this pressing time where multidrug-resistant bacteria are on the rise. Chapter 2 is a meta-analysis of current trends in marine microbial natural product research and an analysis of how much of their chemistry overlaps with the chemistry of terrestrial microbial natural products. Over the past decade, research has greatly shifted to focus on marine microbial natural products, at the expense of marine macro-organism studies. An assessment of the structural overlap between 55,817 published marine and terrestrial microbe and marine macroorganism natural products, using structural fingerprints and scaffold clustering, was enlightening. The results showed that currently 76.7% of the chemistry found in marine microbes is vastly similar to the chemistry isolated from terrestrial microbes. This overlap is mainly due to the use of terrestrial isolation and culturing methods that select for the growth of terrestrial-like bacteria instead of unique marine bacteria. As a result, the unique chemistry associated with truly marine microbe species that are in close symbiotic relationships with marine macro-organisms is being missed. Chapter 3 describes the antimicrobial assay development and screening of a large collection of Australian marine invertebrate specimens for activity against four different strains of bacteria. It resulted in 12.5% of all the specimens tested, showing activity against the drugresistant strain of Staphylococcus aureus (MRSA) but lower bioactivity rates against Pseudomonas aeruginosa (0.76%) and Escherichia coli (0.76%). This illustrates how much harder it is to find activity against Gram-negative bacteria such as P. aeruginosa and E. coli. To investigate this challenge further, drug combination screening was undertaken to assess the potential of resurrecting antibiotics, for the use against bacterial strains that have developed resistance, by combining the antibiotic with marine invertebrate extracts. The combinatorial assays were unsuccessful, thus for further investigations I concentrated on the specimens that exhibited activity in the main assay. Analysis of the sponge specimen Aaptos aaptos that showed activity against S. aureus resulted in the isolation of demethylaaptamine as the bioactive component. Small quantities of a series of peptides with molecular weights in the range of 3,000- 4,000 Da were also isolated from the sponge. Unfortunately, a detailed structure determination could not be undertaken due to COVID-19 state border restrictions, which prevented recollection of the sponge. The subsequent two chapters report on the chemistry of antimicrobial bioactive marine invertebrate extracts. Chapter 4 describes the structures of two new betaine molecules isolated from the bryozoan Amathia lamourouxi. Their structures were determined through analysis of 1D and 2D NMR and mass spectrometric data. Crude extracts of the specimen showed antimicrobial activity at 2.5 mg/mL. Although the yield of active compounds was too small to be completely isolated and identified they were associated with brominated alkaloids. Unfortunately, recollection of this species was also hindered by state border closure due to the COVID-19 pandemic. Chapter 5 describes the isolation and identification of two new amphiphilic polyamines that together with a mixture of relatives were extracted from the marine sponge Aaptos lobata. The two pure compounds and the mixture of amphiphilic compounds showed moderate bioactivity against both drug sensitive and resistant S. aureus, and P. aeruginosa. Chapter 6 describes a multiplatform investigation of the chemistry of the ascidian B. leachii. This species was targeted because it had a similar chemical profile to Aaptos aaptos, small alkaloid and large (>3500 Da) peptide and was more accessible after the COVID-19 state border closures. The investigation used different analytical tools like LC-MS and advanced NMR techniques, including DOSY to characterise the diversity of compounds found in the mixture, while MALDITOF imaging was used to identify the specific locations of these metabolites within the ascidian tissue. This study demonstrated the power of MALDI imaging to provide an insight into the chemical ecology of marine species and helped to establish relationships between marine invertebrates and their associated microorganisms. This finding will aid future specific targeting of tissue regions within marine invertebrates for symbiotic microbe isolation and identification of natural products. Finally, Chapter 7 combines and discusses all the findings of this thesis and examines the future of marine drug discovery. The research reported here has explored the chemical diversity of microbial natural products, discovered new compounds, some with antimicrobial activity, and investigated the chemistry of marine invertebrates and their interesting symbiotic relationship with microorganisms.

Resumen
Cette thèse s’inscrit dans un contexte d’investigations du métabolome de souches fongiques marines en vue de l’étude des interactions chimiques entre organismes marins et de la valorisation de produits naturels. La souche Penicillium restrictum MMS417 a été isolée de moules Mytilus edulis. Lors d’un screening biologique réalisé au sein du laboratoire MMS (Mer, Molécules, Santé), cette souche a présenté une activité cytotoxique sur lignée cellulaire tumorale. Notre travail s’est donc porté sur cette souche avec trois axes de recherche : premièrement, une approche OSMAC couplée à un profilage métabolique par UHPLC-HRMS/MS a été réalisée sur 7 milieux de culture, dont un milieu original à base d’extrait de moules (MES -Mussel Extract Sucrose). Deux conditions osmotiques pour chaque milieu ont été utilisées : l’une utilisant de l’eau distillée (ED) et l’autre de l’eau de mer reconstituée (EDM). L’étude métabolomique non-ciblée et la construction du réseau moléculaire de l’extrait MES-EDM ont montré que la souche MMS417 exprimait spécifiquement la voie de biosynthèse aboutissant à des composés de type pyran-2-one sur milieu MESEDM dont des analogues originaux. A partir d’une culture à grande échelle, des travaux d’isolement et de purification guidés par la spectrométrie de masse puis d’analyse structurale ont abouti à la description de douze pyran-2-ones dont sept produits naturels originaux. Une évaluation biologique préliminaire de certains de ces composés a été réalisée (cytotoxicité sur lignée cancéreuse humaine KB, tests antibactériens, test anti Quorum Sensing), ainsi qu’une évaluation in silico d’inhibition de la protéine phosphatase PTP1B. Le second axe de recherche a concerné l’étude de la biosynthèse des différentes pyran-2-ones produites par cette souche. Une étude cinétique sur milieu MES-EDM a été effectuée pendant une durée 11 jours pour comprendre l’enchaînement des différentes étapes biosynthétiques menant à la production des pyran-2-ones observées chez MMS417. Un réseau moléculaire « dynamique » a été élaboré à partir des profils UHPLC-HRMS/MS, qui montre l’évolution des clusters d’ions au cours de la croissance fongique. L’analyse ciblée de l’évolution cinétique du sous-réseau des pyran-2-ones, et l’isolement d’un précurseur biosynthétique original, a permis de proposer des hypothèse sur cette voie de biosynthèse. Enfin, une troisième approche a concerné l’étude du lipidome de la souche MMS417, celle-ci produisant une fraction lipidique extrêmement abondante sur milieu MES-EDM. Pour cela, les extraits issus de l’étude OSMAC ont été analysés à la fois par UHPLC-HRMS (méthode lipidomique, ionisations positive et négative) et par profilage GC-MS des extraits lipidiques totaux après transesterification en esters méthyliques d’acides gras. Une analyse multi-blocs a été développée pour concaténer et traiter de façon globale les quatre jeux de données disponibles : profils UHPLC-HRMS « métabolites spécialisés », profils « lipides-(+/-) » et profils « GC-MS acides gras ». Cela a mis en évidence l’influence de la présence de moules et d’eau de mer sur la production de globale de lipides et en particulier de certains acides gras inhabituels
This thesis falls within the context of investigations of the metabolome of marine fungal strains for the study of chemical interactions between marine organisms and the valorization of natural products. A Penicillium restrictum MMS417 strain was isolated from blue mussels Mytilus edulis. During a biological screening carried out in the MMS laboratory (Mer, Molécules, Santé), this strain exhibited a cytotoxic activity on a tumor cell line. Our work, therefore, focused on this strain with three scopes of research: first, an OSMAC approach coupled with UHPLC-HRMS/MS metabolic profiling was carried out on 7 culture media, including an original medium based on mussel extract (MES -Mussel Extract Sucrose). Two osmotic conditions were also used for each medium: one using distilled water (ED) the other using artificial seawater (EDM). An untargeted metabolomics study together with the construction of the molecular network of the MES-EDM extract showed that the MMS417 strain specifically expressed on MES-EDM medium a biosynthetic pathway leading to pyran-2-one type compounds including original analogues. From a large-scale culture, a mass spectrometry- guided isolation and purification work followed by structural analyses resulted in the description of twelve pyran-2-ones, including seven original natural products. A preliminary biological evaluation of some of these compounds was carried out (cytotoxicity on human cancerous line KB, antibacterial tests, anti Quorum Sensing test), as well as an in silico evaluation of inhibition of the PTP1B protein phosphatase. The second line of research concerned the study of the biosynthesis of the different pyran-2-ones produced by this strain. A time-series study on the MES-EDM medium was carried out for 11 days to understand the sequence of the different biosynthetic steps leading to the production of pyran-2-ones observed in MMS417. A "dynamic" molecular network was developed from UHPLC-HRMS/MS profiles, which showed the evolution of ion clusters during fungal growth. The targeted analysis of the kinetic evolution of the pyran-2-ones subnetwork, and the isolation of an original biosynthetic precursor, allowed us to propose hypotheses on this biosynthetic pathway. Finally, a third approach concerned the study of the lipidome of the MMS417 strain, this latter producing an extremely abundant lipid fraction on MES-EDM medium. For this purpose, extracts from the OSMAC study were analyzed both by UHPLC-HRMS (lipidomic method, positive and negative ionizations) and by GC-MS profiling of the total lipid extracts after transesterification into fatty acids methyl esters. A multi-block analysis has been developed to concatenate and comprehensively process the four available datasets: UHPLC-HRMS “specialized metabolites” profiles, “lipid - (+/-)” profiles, and “GC-MS fatty acid” profiles. This highlighted the influence of the presence of mussel and seawater on the production of lipids and on some unusual fatty acids

Resumen
This thesis is about the historical geography of scientific knowledge production at sea. It focuses on three expeditions of exploration and discovery undertaken, respectively, by France, the United States of America, and Britain, that in the late 1830s sailed into the southern oceans. These voyages marked the last such expeditions to travel by sail alone and came before an acknowledged period of specialized interest in investigating the oceans and the marine environment, exemplified by the sailing of HMS Challenger in 1872. The expeditions share a commonality of period and of destination: their study together provides a hitherto overlooked opportunity to analyse practices of experimentation on, and investigation of, the natural history and physical properties of the marine environment that were integral to the construction of scientific knowledge about the oceans at that time. By attention to archival records, personal correspondence, diaries, published travel narratives and representations of marine phenomena in the form of illustrations, sketches, preserved specimens and displays of numerical material, this thesis examines quotidian shipboard practices to show how the production of scientific ‘facts’ was a matter of constant negotiation between people, weather, instruments and vessels – that occurred as a by-product of the running of the ship as well as of more defined programmes of study by civilian naturalists and naval staff. Informed by work in the history of science, Science and Technology Studies (STS) and Actor-Network Theory (ANT), this thesis highlights how attending to practice in the ambiguous, heterotopic space that was the expedition vessel can reveal the origins of a new, specialized, discipline: what I call here a proto-oceanography. This covers those scientific practices undertaken primarily at sea and from the ship: depth measurement, sea temperature and chemistry, the height of waves, collection of marine specimens and coastal topography, but not those primarily land-based activities such as astronomy, meteorology and terrestrial magnetism. By focusing on work carried out on board ship rather than on land, this thesis offers new insights into the practices of marine investigation and experimentation and the complexities of interrogating a space which was visualised primarily through instruments. This thesis examines how at-sea cultures of collection, measurement and representation can inform geographically nuanced analyses of the production of scientific knowledge.

Wagner, Daniel. The Ocean Exploration Trust 2023 Field Season. Ocean Exploration Trust, abril de 2024. http://dx.doi.org/10.62878/vud148.

Texto completo
Resumen
This annual report marks the fifteenth year anniversary of Ocean Exploration Trust’s (OET) E/V Nautilus exploring poorly known parts of our global ocean in search of new discoveries. Since its first season in 2009, E/V Nautilus has conducted a total of 158 expeditions that explored our ocean throughout the Black Sea, Mediterranean, Atlantic, Caribbean, and Pacific for a total of 1,970 days at sea (~5.5 years). These scientific expeditions included a total of 1,017 successful ROV dives, as well as mapped over 1,053,000 km2 of seafloor. The results of these exploratory expeditions have been summarized in over 300 peer-reviewed scientific publications covering a wide range of scientific disciplines, including marine geology, biology, archaeology, chemistry, technology development, and the social sciences. Throughout its 15-year history, E/V Nautilus has been not only a platform for ocean exploration and discovery, but also an inclusive workspace that has provided pathways for more people, especially those early in their careers, to experience and enter ocean exploration professions. It has also catalyzed numerous technological innovations, multi-disciplinary collaborations, and inspired millions through OET’s extensive outreach initiatives. The 2023 field season was no exception, with E/V Nautilus undertaking 12 multi-disciplinary expeditions that explored some of the most remote and poorly surveyed areas in the Pacific, all of which included numerous activities to share expedition stories with diverse audiences across the globe.

Texto completo
Resumen
A digital compilation of updated postglacial marine limits was completed in the coastal regions of central mainland Nunavut and northern Manitoba between Churchill and Queen Maud Gulf. The compilation builds on and updates previous mapping of the marine limits at an unprecedented scale, making use of high-resolution digital elevation models, new field-based observations of the marine limit and digital compilations of supporting datasets (i.e. marine deltas and marine sediments). The updated mapping also permits a first-hand, knowledgedriven interpolation of a continuous limit of marine inundation linking the Tyrrell Sea to Arctic Ocean seawaters. The publication includes a detailed description of the mapping methods, a preliminary interpretation of the results, and a GIS scalable layout map for easy access to the various layers. These datasets and outputs provide robust constraints to reconstruct the patterns of ice retreat and for glacio-isostatic rebound models, important for the estimation of relative sea level changes and impacts on the construction of nearshore sea-transport infrastructures. They can also be used to evaluate the maximum extent of marine sediments and associated permafrost conditions that can affect land-based infrastructures, and potential secondary processes related to marine action in the surficial environment and, therefore, can enhance the interpretation of geochemical anomalies in glacial drift exploration methods. A generalized map of the maximum limit of postglacial marine inundation produced for map representation and readability also constitutes an accessible output relevant to Northerners and other users of geoscience data.

Lane, L. S., K. M. Bell y D. R. Issler. Overview of the age, evolution, and petroleum potential of the Eagle Plain Basin, Yukon. Natural Resources Canada/CMSS/Information Management, 2022. http://dx.doi.org/10.4095/326092.

Texto completo
Resumen
New mapping, biostratigraphy, geochemistry, and organic petrology results have led to new insights into the structural evolution, depositional history, and resource potential of the Eagle Plain Basin. Apatite fission-track modelling resolves at least two distinct heating-cooling cycles and suggests that sediment was sourced from the east, as well as from the south. A recently identified marine-slope setting in the west of the basin represents a new petroleum play. Advances in understanding the age and depositional history of the Eagle Plain Group derive from new fossil localities, a new bentonite age, and detrital zircon data. Initiated in the Cenomanian, or possibly latest Albian, deposition continued until the late Maastrichtian, although post-Coniacian deposits may have been subsequently eroded, or bypassed across southern parts of the basin. New petroleum resource appraisals include new petroleum exploration-play concepts, as well as qualitative assessments of unconventional oil and gas potential.

Texto completo
Resumen
Exploration for hydrocarbons began in the Labrador-Baffin Seaway in the 1960s; activity along the Labrador margin is still ongoing. A moratorium on exploration activities in the Canadian Arctic was enacted in 2016, halting drilling and data acquisition in western Davis Strait and along the Baffin Island margin. The exploration for hydrocarbons along the West Greenland margin ceased in 2021. Despite the presence of all hydrocarbon system elements as well as direct indicators of at least one working hydrocarbon system (e.g. slicks and/or seeps, oil and/or gas shows), no commercially viable accumulations of hydrocarbons have been discovered in the region. Potential sea-surface hydrocarbon slicks have been identified throughout the study region using synthetic aperture radar, but only the slick offshore Scott Inlet (Nunavut) has been directly linked to seafloor hydrocarbon seepage.

Resumen
ALKOR cruise AL583 took place as part of the EMFF (European Maritime and Fisheries Fund)‐funded projects BASTA (Boost Applied munition detection through Smart data detection in and AI workflows; https://www.basta‐munition.eu) and ExPloTect (Ex‐situ, near‐real‐time detection compound detection in seawater) (also EMFF‐funded). It was the continuation of the munition monitoring started within the BMBF‐funded project UDEMM (Environmental Monitoring for the Delaboration of Munition in the Sea; https://udemm.geomar.de/) and is already part of the new project CONMAR (https://conmar‐ munition.eu/) as part of the DAM mission sustainMare (https://www.sustainmare.de/). Additional sampling supported chemical analysis method development within the MarTERA project AMMOTRACe (Marine AMMunitiOn dump site exploration by surface‐ and underwater‐based laser mass spectrometric TRACing technology; https://www.geomar.de/en/ammotrace ). The original plan was to first work for one week in the North Sea and have a crew change after one week in Kiel and continue working in the Baltic Sea. This plan changed; ALKOR worked instead in Baltic Sea in support of for the Federal Public Prosecutor General and the Federal Police during the first week. The change of crew happened on 18th October in Kiel and the original Baltic Sea cruise was conducted as planned.

Resumen
The city’s relationship with its margins in the context of how state affects the lives of the people has increasingly become an important site of research—especially how pressures of governance split the nature of power and violence of the state at the margins vis-à-vis the city—where the experience of the state and how it operates is starkly different from how it unfolds for the middle-classes of the city. Education in this context has been an under researched area.

Herring, Theodore, Justin Tweet y Vincent Santucci. Wind Cave National Park: Paleontological resource inventory (public version). National Park Service, junio de 2023. http://dx.doi.org/10.36967/2299620.

Texto completo
Resumen
Wind Cave National Park (WICA), the first cave in the world to become a national park, is famous for the park’s namesake feature. Wind Cave, named for the noticeable wind-flow patterns observed as air moves in and out of the natural cave entrance, is currently the third longest cave system in the United States and seventh longest in the world. Wind Cave formed when groundwater dissolved buried layers of the fossiliferous Madison Limestone, which were deposited during the Mississippian subperiod approximately 359 to 347 million years ago. In addition to the Madison Limestone, several other formations are exposed within the park, dating from the early Proterozoic to the Holocene. The presence of fossils within the park has been known since at least the late 19th century when early settlers explored the cave to turn the geologic feature into a tourist attraction. However, most of the geologic work conducted during the park’s history has focused on the exploration and development of the cave itself, rather than its fossils. Paleontology became a bigger focus in the late 20th century when the park partnered with the South Dakota School of Mines and Technology to recover and research fossils found within the cave and on the park’s surface. Other partnerships include those with the Mammoth Site of Hot Springs and Northern Arizona University, through which researchers have studied Quaternary cave deposits found across the park. In ascending order (oldest to youngest), the geologic formations at WICA include undifferentiated lower Proterozoic rocks (Precambrian), Harney Peak Granite (Precambrian), Deadwood Formation (Cambrian–Ordovician), Englewood Limestone (Devonian–Mississippian), Madison Limestone (Mississippian), Minnelusa Formation (Pennsylvanian–Permian), Opeche Shale (Permian), Minnekahta Limestone (Permian), Spearfish Formation (Permian–Triassic), Sundance Formation (Middle–Upper Jurassic), Unkpapa Sandstone (Upper Jurassic), Lakota Formation (Lower Cretaceous), Fall River Formation (Lower Cretaceous), White River Group (Eocene–Oligocene), and Quaternary alluvium, conglomerate, and gravel deposits. The units that are confirmed to be fossiliferous within the park are the Deadwood Formation, Englewood Limestone, Madison Limestone, and Minnelusa Formation, which contain a variety of marine fossils from a shallow sea deposition environment; the Sundance Formation, which has much younger marine fossils; the Lakota Formation, which has yielded petrified wood; and the White River Group and Quaternary deposits, which contain vertebrate and invertebrate fossils deposited in and near freshwater streams, lakes, and ponds. Many of the fossils of WICA are visible from or near public trails and roads, which puts them at risk of poaching or damage, and there is evidence that fossil poaching occurred at several of the Klukas sites soon after they were discovered. Furthermore, there are several fossil sites on the tour routes within Wind Cave, which are of value to interpretation and the park experience. WICA has implemented cyclic fossil surveys in the past to monitor site conditions, and it is recommended that this paleontological resource monitoring be continued in the future.
