Streszczenie:
A resurgent interest in the gas potential of the Gulf of Papua has been enhanced by the recent announcement of developing new LNG facilities in Port Moresby. Petroleum Geo-Services (PGS) has recently acquired a 6,000-km2 Multi-Client 3D (MC3D) survey in the gulf. Although most of the discoveries in PNG are from the highland areas, the gulf is a proven hydrocarbon province with gas/condensate accumulations previously discovered in several reef build-ups. It is thought that sediments from the Papuan Fold Belt produced clastic dominated deltas in the Gulf area. Although this play is untested offshore, there is evidence these sandy facies exist and could contain hydrocarbons. On the first phase of acquisition/interpretation, an efficient screening workflow called Prospect Scanner, developed to highlight areas of AVO effects in large 3D seismic datasets, was tested. It uses pre-stack seismic time migrated (PSTM) gathers to extract AVO attributes that are then inverted to derive relative acoustic and shear impedance volumes. Using idealised cross-plots, the relationship between Vp/Vs ratio and the Ip values gives a good indication of the fluid and lithology of the tested interval. The results are loaded into a conventional interpretation package for interpretation/visualisation. Prospect Scanner has highlighted previously undrilled turbidite and basin floor fan prospects in the region. The Vp/Vs versus Ip cross-plot shows clustering of the sand anomaly and good separation from the majority of the plot. These points correspond to the idealised location for a gas sand. Past concerns about lateral prediction of reservoir presence and quality associated with the basin floor fans can be addressed through this workflow.

The frontier and underexplored Cape Vogel Basin (CVB), north of the Papuan Peninsula, is thought to be underlain by Late Palaeocene–Eocene oceanic crust and overlain by Cenozoic sediments. Several impartial data provide evidence of working petroleum system(s) including a flow of oil from a 1920s well, and two 1970s wells that encountered minor hydrocarbon traces and good source material. The 1970s wells chased Miocene reef plays (like the discoveries in the Gulf of Papua). No Miocene reefs were encountered, with both wells terminating in volcanics. Integration of open-file 2D seismic, modern 2D PSDM seismic and shipborne gravity and magnetic data improves the subsurface imaging and thus understanding of prospectivity. The data reveal a significant sedimentary section (including Mesozoic sediments) and that the volcanics are not laterally continuous (i.e. products of short periods of volcanism). The data also suggests several Mesozoic–Cenozoic plays (e.g. carbonate reefs, incised canyons). Repeatable sea surface slicks, and observable bottom-simulating reflectors and direct hydrocarbon indicators, also provide evidence of working petroleum system(s). It is hypothesised that the CVB has affinities with the Gulf of Papua with the extension of the Australian craton north of the Papuan Peninsula, with widespread deposition in the Mesozoic–Cenozoic, and with source rocks estimated to be within the hydrocarbon generative window. With incorporation of onshore data and presence of significant gravity low, it is postulated that the central and north-west were less susceptible to Late Cretaceous and Palaeocene differential uplift and erosion (related to Coral Sea breakup and extension), and thus have a higher chance of Late Mesozoic preservation.

Based on the examination of 26 499 female and 17 666 male specimens, the reproductive biology of P. ornatus is discussed with spatiotemporal reference to the annual breeding migration from northern Torres Strait to the Gulf of Papua. Migration commences generally in August with ovary development, mating and initial oviposition occurring during migration. Larval release normally commences once the migration has terminated on the reefs of the eastern seaboard in the Gulf of Papua. At the conclusion of the migration, marked segregation of the sexes occurs, with males entering shallow water (< 3 m) before females, who frequent deeper water (3-15 m) until their eggs have hatched. During the breeding season (November- April), females produce up to three broods. Fecundity is determined for 33 females in the carapace size range 75.4-121.0 mm. No significant egg loss during incubation was detected, but there was an indication of a reduction in the size of each subsequent brood. There appears to be a high post-spawning mortality of migratory lobsters. It is likely that the Gulf of Papua is the major source of larval recruitment in the western Coral Sea, including the east coast of Queensland and Torres Strait.

The Gulf of Papua, Papua New Guinea, is a rapidly changing geomorphic and cultural landscape in which the ancestral past is constantly being (re)interpreted and negotiated. This paper examines the importance of subsurface archaeological and geomorphological features for the various communities of Orokolo Bay in the Gulf of Papua as they maintain and re-construct cosmological and migration narratives. The everyday practices of digging and clearing for agriculture and house construction at antecedent village locations bring Orokolo Bay locals into regular engagement with buried pottery sherds (deposited during the ancestral hiri trade) and thin strata of ‘black sand’ (iron sand). Local interpretations and imaginings of the subsurface enable spatio-temporal interpretations of the ancestors' actions and the structure of ancestral settlements. These interpretations point to the profound entanglement of orality and material culture and suggest new directions in the comparative study of alternative archaeologies.

Papua shoreline has the most extensive area of mangrove in Indonesia. Since this area was rarely studied due to various reasons, the scientific data was difficult to be found. Wondama mangrove, part of Cendrawasih National Park – West Papua, had a promising mangrove forest to be discovered. Preliminary study was carried out in this area to identify how pristine the mangrove area is. The objectives of this study was to analyze mangrove community health and structure. Vegetation structure and canopy coverage data were collected from 107 circular plots included three plot areas (radian: 5 m, 2.5 m and 1 m) which were distributed to determine three plant classes i.e. tree, sapling and seedling, respectively. Present study showed that Wondama mangrove is a pristine mangrove community. It had large size of tree trunk diameter by 19.77± 6.55 cm averagely. Its diameter size affected on low tree density which was less than 1000 tree/ha. Those two parameters were strongly negative-correlated each other. On the other hand, community canopy was highly covered mangrove area by 82.46±6.43%. Rhizophora has mostly dominated in the forest. Mangrove regeneration in Wondama was excellent referring to density and species composition of sapling-seedling levels.

A sequence stratigraphic study was conducted on the Mendi and Darai Limestone Megasequences in the foreland area of the Papuan Basin in Papuan New Guinea. It involved the integrated use of seismic, wireline log, well core and cuttings, strontium isotope age and biostratigraphic data. This study enhanced the understanding of the structure, stratigraphy and depositional architecture of the limestones, and the morphology of the basin at the time of deposition. The results of the study were integrated with published geological and tectonic models for the Papuan Basin to develop a consistent and coherent model for the depositional history of the limestones. Eleven third-order sequences were delineated within the Mendi and Darai Limestone Megasequences. Eight depositional facies were interpreted across these sequences, namely deep-shelf, shallow-shelf, backreef, reef, shoal, forereef, basin margin and submarine fan facies. Each facies was differentiated according to seismic character and geometry, well core and cuttings descriptions, and its position in the depositional framework of the sequence. Deposition of the Mendi Limestone Megasequence commenced in the Eocene in response to thermal subsidence and eustatic sea-level rise. Sedimentation comprised open-marine, shallow-water, shelfal carbonates. During the middle of the Oligocene, the carbonate shelf was exposed and eroded in response to the collision of the Australian and Pacific Plates, or a major global eustatic sea-level fall. Sedimentation recommenced in the Late Oligocene, however, in response to renewed extensional faulting and subsidence associated with back-arc extension. This marked the onset of deposition of the Darai Limestone Megasequence in the study area. The KFZ, OFZ and Darai Fault were reactivated during this time, resulting in the oblique opening of the Omati Trough. Sedimentation was initially restricted to the Omati Trough and comprised deep and shallow-marine shelfal carbonates. By the Early Miocene, however, movement on the faults had ceased and an extensive carbonate platform had developed across the Gulf of Papua. Carbonate reef growth commenced along topographic highs associated with the KFZ, and led to the establishment of a rimmed carbonate shelf margin. Shallow to locally deeper-marine, shelfal carbonates were deposited on this shelf, and forereef, submarine fan and basin margin carbonates were deposited basinward of the shelf margin. The Uramu High and parts of the Pasca High became submerged during this time and provided sites for pinnacle reef development. During the middle of the Early Miocene, a major global eustatic sea-level fall or flexure of the Papuan Basin associated with Early Miocene ophiolite obduction subaerially exposed the carbonate shelf. This resulted in submarine erosion of the forereef and basin margin sediments. Towards the end of the Early Miocene, however, sedimentation recommenced. Shallow-marine, undifferentiated wackestones and packstones were deposited on the shelf; forereef, submarine fan and basin margin sediments were deposited basinward of the shelf margin; and reef growth recommenced along the shelf margin and on the Pasca and Uramu Highs. By the end of the Early Miocene, however, the pinnacle reef on the Pasca High had drowned. During the middle of the Middle Miocene, subtle inversion associated with ophiolite obduction subaerially exposed the carbonate shelf, and resulted in submarine erosion of the forereef and basin margin sediments. Sedimentation recommenced towards the end of the Middle Miocene, however, in response to eustatic sea-level rise and flexure of the crust associated with foreland basin development. Shallow marine, undifferentiated wackestones, packstones and grainstones were deposited on the shelf; carbonate shoals were deposited along the shelf margin; and forereef, submarine fan and basin margin carbonates were deposited basinward of the shelf margin. Carbonate production rapidly outpaced accommodation space on the shelf during this time, resulting in highstand shedding and the development of a large prograding submarine fan complex basinward of the shelf margin. By the Late Miocene, carbonate deposition had ceased across the majority of the study area in response to a major global eustatic sea-level fall or inversion associated with terrain accreation events along the northern Papuan margin. Minor carbonate deposition continued on parts of the Uramu High, however, until the middle of the Late Miocene. During the latest Miocene, clastic sediments prograded across the carbonate shelf, infilling parts of the foreland basin. Plio-Pleistocene compression resulted in inversion and erosion of the sedimentary package in the northwestern part of the study area. In the southeastern part of the Papuan Basin, however, clastic sedimentation continued to the present day.

This thesis takes Kerewo historical consciousness as the frame for an analysis of the ways in which reflections on the past are fundamentally informed by orientations towards the future. In particular, I draw on various representations of the historical event of the killing of missionary James Chalmers in 1901, and its consequences, to explore local conceptions of modernity as a moral state withheld from Kerewo in the absence of a reconciliation with their past. This particular historical episode occupies a central place in contemporary Kerewo understandings of their perceived marginality within the post-Independence state of Papua New Guinea, and more widely in the world system. This marginality is manifest in Kerewo daily experience as a lack of services and infrastructure, despite the presence in the area of a multi-billion dollar resource extraction enterprise. The roots of this perceived lack of ‘modernity’ are sought in the colonial past, and articulated in moral terms through historical narratives. The colonial era emerges from these narratives as the period in which Kerewo were exposed to modernity in its ideological and material forms. Yet, the promises and expectation of an amelioration of life conditions engendered by several colonial discourses never materialised, leaving contemporary Kerewo people with a sense of frustrated modernity. It is the conflation of the colonial era with the idea of modernity that informs Kerewo historical consciousness, and thus it is by ritually addressing the colonial past that Kerewo people seek to transform the ‘frustrated modernity’ of the present into a better future. What emerges from the analysis of the historical and ethnographic material that constitutes the core of this dissertation is that historical consciousness consists fundamentally of a social process – which emerges from the social labour of history- making – to apprehend present conditions through reflection on the past informed by competing orientations toward the future.

Streszczenie:
The Papua New Guinean (PNG) landscape is young and rapidly evolving, with high uplift rates and precipitation rates that exceed 10 m/yr producing high erosion rates. Consequently, the Gulf of Papua, an active foreland basin in southern PNG, receives a large terrigenous sediment flux of ~384 Mt/yr. The fresh and tectonically active Papuan landscape makes the Gulf an ideal location for studying tectonic and climatic impacts on source-to-sink surface processes and basin stratigraphy. This thesis aims to (1) constrain a range of parameters, including tectonic uplift rates, upland erodibility and marine sediment distribution, in order to calibrate a numerical model simulating the Late Quaternary landscape evolution of the Gulf of Papua foreland basin. In addition, this study aims to (2) use the calibrated model to identify temporal and spatial patterns in erosion, fluvial sediment transportation and sediment distribution and composition in the basin. This thesis uses the open-source landscape evolution code Badlands to simulate surface processes in PNG. However, to simulate source-to-sink sediment transfer in the Gulf of Papua it was first necessary to constrain a range of parameters with tectonic and geological constraints specific to the basin. The magnitude, timing and spatial variations in uplift across the Papuan Peninsula were constrained using the present-day elevation of remnants of late Miocene volcanics that were deposited near sea level during the Miocene and have subsequently been uplifted. To constrain upland erodibilities, a series of simulations of the landscape evolution of the Gulf of Papua were run in Badlands, testing the impact of a range of erodibility coefficients on the sediment flux into the Gulf. The sediment loads of simulated rivers were compared to the present-day natural sediment loads of the Fly, Kikori and Purari Rivers to find both an averaged erodibility coefficient for the Gulf of Papua catchment and lithology-specific coefficients. Comparing simulation results to observed sediment accumulation rates in the deep-sea Gulf assisted in constraining the distribution of sediment in the marine environment in Badlands. The calibrated model was then used to simulate the sediment routing system in the Gulf of Papua catchment. Results show an increase in the Plio-Quaternary uplift rate from negligible at sea level along the south-western coast of the Papuan Peninsula to > 600 m/Myr in the peaks of the Owen Stanley Range. Comparisons with present-day fluvial sediment loads constrain the averaged erodibility coefficient in Badlands for the Gulf of Papua to within the range 5.53 – 7.41 x 10−6 yr−1, with an estimated averaged erodibility coefficient of ~7 x 10−6 yr−1 for a resolution of 500 m. Erodibility coefficients for specific lithologies range from ~6.5 x 10−6 yr−1 for metamorphics and granites to ~13.0 x 10−6 yr−1 for soft sediments. Subsequently, the marine accommodation variable was constrained to within the range 0.005 − 0.009, so that the largest depocentres in the Gulf are on the continental slope. A sensitivity analysis reveals that the simulated sediment flux into the Gulf of Papua is more sensitive to changes in precipitation rate than to changes in the uplift rate. These findings permit the simulation of sediment transfer processes in the Gulf of Papua during the Late Quaternary, informing our understanding of the catchment’s surface evolution and the stratigraphy of the deep sea basin. Simulation results suggest that sediment delivered to the eastern Gulf is largely composed of metamorphics and volcanics sourced from the Owen Stanley Range. Changes in sea level have a limited impact on sediment deposition in the east as the narrow, steep continental shelf allows rivers to deliver sediment directly into the deep-sea depocentres, which are compositionally distinct from one another. The mature rivers in the west of the catchment transfer sediment derived from soft sediment, mafics, metamorphics and granites in the Papuan Orogen to the western Gulf of Papua. Marine transgression and highstand in the last 14 Kyr have submerged the wide continental shelf in the western Gulf and prevented rivers from delivering sediment directly into the deep sea. Thus, there has been increased sediment accumulation on the submerged shelf. These results highlight basin morphology, the surface distribution of lithologies and the glacio-eustatic cycle as major controls on the sediment distribution and composition in the marine environment.

Streszczenie:
The mixed carbonate-siliciclastic depositional system in the Gulf of Papua (GoP) was studied by standard sequence stratigraphic method based on a large industry seismic and well datasets, in addition to gravity, multibeam bathymetry, Landsat imagery, and core data. The Cenozoic geological history of the mixed system is represented by four-phase evolutionary model, which includes (1) tectonic, (2)carbonate, (3) carbonate system demise, and (4) siliciclastic phases, defined based on the intensity of such factors as tectonics, eustasy, climate, carbonate production, and siliciclastic supply. During the Late Cretaceous - Paleocene tectonic phase, the Coral Sea spreading triggered extensional tectonics, consequent uplift, and erosion which formed a structural configuration controlling the later evolution of the system. During the Eocene and late Oligocene - middle Miocene carbonate phase, basinal scale sedimentary geometries are largely controlled by eustatic seal level fluctuations. Because the geometry pattern identified within the carbonate sequences in the GoP mimics contemporaneous sedimentary geometry pattern observed in other pure carbonate and even siliciclastic depositional systems around the world, eustasy had to be the major factor influencing the GoP mixed system during this second phase. Although partial carbonate demise was observed during the early Miocene, the demise phase per se occurred during the late middle Miocene exposure of the system and its subsequent drowning in the early late Miocene, and was probably related to a major sea level rise enhanced by fold belt loading. During the Oligocene Peninsular Orogeny, the siliciclastics did not influence the carbonate system because they were trapped in the Aure Trough, a foreland basin to the northeast of the study area. The siliciclastic phase in the GoP was initiated during the late Miocene Central Range Orogeny. At that time and in the early Pliocene, siliciclastic infill was limited to the deep troughs in northeast corner of the GoP. The major siliciclastic input and progressive burial of the GoP carbonate system only occurred in the late Pliocene, as a response to the contemporaneous renewed uplift and exhumation of Peninsular region. During this fourth phase, the siliciclastics infilled 3-4 km deep troughs and completely buried the most of the carbonate system. The northern end of the Great Barrier Reef along with several large isolated carbonate platforms located far away from the siliciclastic sources are still active today.

Streszczenie:
The elasmobranch fauna of Papua New Guinea (PNG) and its interaction with fisheries has been poorly studied in the past. Fisheries generally adversely impact elasmobranchs due to their low productivity life histories. Without fishery and region specific data on elasmobranchs the impact on their populations cannot be fully understood and subsequent development of appropriate fisheries management and conservation measures cannot be achieved. The objectives of this thesis were to address some of these data gaps for the Gulf of Papua Prawn Fishery (GoPPF) in PNG through the assessment of biological and ecological parameters of species caught as bycatch and the development of an ecological risk assessment for all elasmobranch species caught in the fishery. The ecological component of this work focused on the feeding relationships among the Australian blackspot shark Carcharhinus coatesi, the milk shark Rhizoprionodon acutus and the Australian sharpnose shark Rhizoprionodon taylori. Rhizoprionodon acutus had a more specific diet compared to the other species, feeding almost exclusively on teleosts while C. coatesi and R. taylori had more diverse diets that had greater overlap. The limited sampling in this study did not fully characterise the diets of the three species, however, it does provide the first empirical evidence of trophic relationships between these sympatric sharks and their prey for the Gulf of Papua. The biology of R. taylori and C. coatesi was investigated through determination of their age, growth and maturity. Ages were determined from vertebrae samples. Length at age data were fitted to several models in a multi-model information theoretic approach to determine which model provided the best fit. Maturity was analysed using logistic regression of maturity categories recorded from samples combined with size and age data. These studies provide an understanding of the growth rate and pattern of each species and the length and age which males and females of each species reach reproductive maturity. To assess the biology of R. taylori, 186 samples were collected comprising 131 females (31-66 cm TL) and 55 males (31-53 cm TL). The lack of small individuals close to the size at birth made fitting of growth curves more difficult, two methods (fixed length at birth and additional zero aged individuals) accounting for this were trialled. The von Bertalanffy growth model provided the best fit to the data when used with a fixed length-at-birth (L0 = 26 cm TL). Males (????∞= 46 cm TL, k = 3.69 yr-1, L50 = 41.7 cm TL and A50 = 0.5 years) grew at a faster rate and matured at smaller sizes and younger ages than females (????∞ = 58 cm TL, k = 1.98 yr-1, L5o = 47.0 cm TL and A50 = 0.93 years). However, none of the methods to account for the lack of small individuals fully accounted for this phenomenon, and hence the results remain uncertain. Despite this, the results reaffirm the rapid growth of this species and suggest that the Gulf of Papua population may grow at a faster rate than Australian populations. Rhizoprionodon taylori is possibly well placed to withstand current fishing pressure despite being a common bycatch species in the GoPPF. However, further research needs to be undertaken to estimate other key life history parameters to fully assess the population status of this exploited shark species. Carcharhinus coatesi is a similar small bodied coastal shark to R. taylori but some differences were observed in its growth and maturity parameters. The von Bertalanffy growth model also fit the data best for C. coatesi; parameters were L0 = 40.6 cm ± 0.8, L∞ = 74.8 cm ± 2.1, k = 0.33 year1 ± 0.06. Length-at-maturity analysis indicated that males reach maturity at L50 = 66.3 cm (CI: 63.8, 71.4) and L95 = 71.6 (C1: 64.6, 74.2) cm while females matured at L50 = 71.4 cm (CI: 61.5, 72.01) and L95 = 72.5 cm (CI: 62.7, 74.0). Age-at-maturity estimates showed that both males (A50 = 5.1 years (CI: 4.6, 7.1), A95 = 6.4 years (CI: 5.1, 7.2) and females (A50 = 5.3 years (CI: 3.5, 8.7) and A95 = 7.4 (CI: 3.6, 8.8) years) reach maturity at about the same age, but in comparison to other small bodied carcharhinids, C coatesi has slower growth in early life stages and reaches maturity at a later age. This biological trait along with a small litter size indicates that the population of C. coatesi in the Gulf of Papua may be more susceptible to decline as a result of fishing. An Ecological Risk Assessment (ERA) was conducted to estimate the susceptibility of species caught in the fishery and the potential for a species to recover from population declines due to fishing if they occur. Of the 39 elasmobranch species encountered as bycatch in the fishery 10 were classified as being at low risk, 26 subjected to medium risk and 3 at high risk. The species at high risk were the Australian blackspot shark C. coatesi, the eyebrow wedgefish Rhynchobatus palpebratus and the blackspotted whipray Maculabatis astra. This is the first ERA conducted for this fishery. The findings provide fishery managers with information to implement an ecosystem-based approach to managing the fishery to reduce bycatch and improve the sustainability of the GoPPF. This thesis has provided new information on the diet, age, growth, maturity and the potential risk of species suffering population declines from being caught in the GoPPF. These outcomes have implications for fisheries management and conservation of species in PNG and the surrounding regions. The areas of study begin to address current data gaps for this fishery and also set the foundation for future work to improve fisheries management and protect the survival of species through conservation measures in PNG.

Streszczenie:
The Great Barrier Reef (GBR) margin, located on the continental margin between Papua New Guinea and northeast Australia, is the largest extant example of a tropical mixed siliciclastic-carbonate depositional system. It is constructed by the combined input of terrigenous siliciclastic sediment delivered through riverine transport and biogenous carbonate sediment from neritic and pelagic production. This study investigates late Quaternary changes in sediment dispersal and accumulation on the slopes of this margin. Sedimentation across the GBR mixed system also serves as an important analog for understanding deposition on other extant and ancient systems and provides insight into global change, geochemical cycling, and resource management. Several concepts (e.g., reciprocal sedimentation, coeval sedimentation) have been proposed to explain spatial and temporal variations in siliciclastic and carbonate components. While these concepts are frequently used to evaluate ancient tropical mixed systems, they are rarely assessed in the Quaternary, an interval where the magnitude and timing of sea level are relatively well-constrained, and precise dating techniques can be used. These studies of the GBR mixed system integrate a full suite of data including core, seismic, and multi-beam bathymetry to gain a quantitative understanding of the GBR system and to evaluate reciprocal sedimentation concepts. Results indicate that slopes along the GBR margin have a complex depositional history. Sea level, climate, and margin physiography are all important depositional controls affecting timing, location, and mechanism of sediment dispersal. Reciprocal sedimentation can be used to predict carbonate accumulation. However, this approach must be combined with a firm understanding of sedimentary controls and processes to accurately predict siliciclastic accumulation along this margin.
