Decommissioning Research Needs for Offshore Oil and Gas Infrastructure in Australia

Frontiers in Marine Science, Год журнала: 2021, Номер 8

Опубликована: Июль 29, 2021

When offshore oil and gas infrastructure is no longer needed, it either removed, partially left in place, or place but repurposed. These processes are collectively referred to as decommissioning. Australian legislation requires companies develop acceptable plans for the safe removal of all at end a project’s life. Over next 50 years, liability this decommissioning Australia expected exceed US$45 billion. Unlike countries such Norway, United Kingdom Netherlands, activities their infancy, with only three cases (to date) Commonwealth waters where has been removed part Differences between marine environment that other regions around world decommissioning-related research better progressed include very low sedimentation rates, both tropical temperate habitats, different species composition, primary production, frequent cyclones, well unique sociodemographic cultural characteristics. Accordingly, outcomes decision support tools used identify preferred options may not be equally applicable Australia. Here we describe risk impact assessment Australia, full “base case” regulatory default, including partial and/or repurposing might provide similar when environmental, social, economic seafood safety aspects considered. Based on our review propose an integrated framework needs meet legislative requirements gaps need addressed inform decision-making context.

The super wicked problem of ocean health: a socio-ecological and behavioural perspective

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2022, Номер 377(1854)

We are dependent on our oceans for economic, health and social benefits; however, demands escalating, the state of is deteriorating. Only 2% countries track to achieve desired outcomes sustainable development goal (SDG 14) by 2030, changes needed prevent further degradation, or limit impact existing not being undertaken fast enough. This paper uses a socio-ecological lens explore nature actors behaviours change at local, community, state, national international levels, introduces need technology, information- knowledge-sharing, policy as interconnected mediators, that work both in concert, independently, address 'super wicked' problem ocean promote resilience. recommend develop transformational teams leaders, well transformative policies within holistic integrated system ensure initiatives greater than sum their parts actual, realistic, achievable evidence-informed pathways change. article part theme issue 'Nurturing resilient marine ecosystems'.

Climate velocity drives unexpected southward patterns of species shifts in the Western Mediterranean Sea

Ecological Indicators, Год журнала: 2024, Номер 160, С. 111741 - 111741

Опубликована: Март 1, 2024

The Mediterranean Sea is one of the most vulnerable ecosystems in world due to variety and severity cumulative impacts faced, including high climate risk. Species distributions are expected track niches response warming, with meridionalization (i.e. northern spread native warm-water species) as a common documented response. However, environment also highly heterogeneous structured at regional scales, constraining generalized species responses. Based on long-term monitoring data demersal communities Western (1994–2019), we calculated seven indicators characterizing space–time patterns multiple their temporal rates change. Simultaneously, computed velocity based variation sea surface temperature. Subsequently, modeled velocity, taking into account species' temperature depth preferences. Contrary northward expectation consequence communities' meridionalization, large number have shifted toward south southwest higher medium r values averaged warmer conditions. In general, cold-water an affinity for low moderate mean wide narrow ranges were better tracking velocity. Furthermore, distributed over continental shelf towards shallower inshore waters opposed further away contrary priori expectations shifts deeper waters, following bathymetric gradient. dispersion spatial heterogeneity these expanded, although not explicitly suggesting additional synergistic drivers. Our results confirm importance useful metric predicting responses sub-regional levels provide information scales required embracing local management measures.

Operationalising Indigenous data sovereignty in environmental research and governance

In the face of climate change, Western environmental research and governance processes institutions are increasingly seeking to learn from harness Indigenous peoples knowledges, perspectives, practices land water management. There both opportunities risks for groups exploit these (re)connect with their homelands reinvigorate dormant cultural practices. This article considers issues by highlighting barriers, risks, opportunities, across three case study sites – burning, Geographic Information Systems (GIS) mapping, marine science. We offer data sovereignty as guiding principles a practical blueprint that can make safe intercultural collaborations mitigating against perverse or unintended consequences knowledge theft, well maximising foster sustainable self-determination self-governance.

Ancient DNA and osteological analyses of a unique paleo-archive reveal Early Holocene faunal expansion into the Scandinavian Arctic

Science Advances, Год журнала: 2024, Номер 10(13)

Paleo-archives are essential for our understanding of species responses to climate warming, yet such archives extremely rare in the Arctic. Here, we combine morphological analyses and bulk-bone metabarcoding investigate a unique chronology bone deposits sealed high-latitude Storsteinhola cave system (68°50′ N 16°22′ E) Norway. This deposit dates period warming from end Late Glacial [~13 thousand calibrated years before present (ka cal B.P.)] Holocene thermal maximum (~5.6 ka B.P.). Paleogenetic allow us exploit 1000s morphologically unidentifiable fragments resulting high-resolution sequence with 40 different taxa, including not previously found here. Our record reveals borealization both marine terrestrial environments above Arctic Circle as naturally recurring phenomenon past periods providing fundamental insights into ecosystem-wide that ongoing today.

Evaluation of MPA designs that protect highly mobile megafauna now and under climate change scenarios

Marine protected area (MPA) designs, including large-scale MPAs (LSMPAs; >150,000 km2), mobile (fluid spatiotemporal boundaries), and MPA networks, may offer different benefits to species could enhance protection by encompassing scales of animal movement. We sought understand how well LSMPAs benefit nine highly-mobile marine in the tropics now into future by: 1) evaluating current range overlap within a LSMPA; 2) under climate change projections; 3) theoretical designs these species. focused on Palmyra Atoll Kingman Reef, 2000 km2 1.2 million U.S. Pacific Remote Islands National Monument (PRIMNM) that contains megafauna (reef pelagic fishes; sea turtles; seabirds; cetaceans) reflecting behaviors habitat use. Our approach is useful for effectiveness Palmyra-Kingman PRIMNM protecting species, tropical general, informing design. Stationary provided at varying scales. Reef manta rays (Mobula alfredi), grey reef sharks (Carcharhinus amblyrhynchos), green turtles (Chelonia mydas), bottlenose dolphins (Tursiops truncatus) had overall small ranges (<100 km from Palmyra-Kingman) stationary contained heterogenous habitats. Yellowfin tuna (Thunnus albacares), sooty terns (Onychoprion fuscatus), red-footed boobies (Sula sula), great frigatebirds (Fregata minor), melon-headed whales (Peponocephala electra) navigated complex oceanographic processes most shift with features thermal fronts, cyclic regions elevated productivity, eddies, if relationships are established predictable.
