Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Янв. 2, 2024

Abstract Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field on Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of LCVF has not yet been published, hindering inclusion biogeographic analyses fauna. There is an urgent need to understand diversity, spatial distribution ecosystem function biological communities along AMOR, which will inform environmental impact assesments future deep-sea mining activities region. Therefore, our aim with this paper provide fauna at present insight into food web community. The high degree novelty, five new species previously described another ten awaiting formal description. Most from are either hydrothermal specialists or have reported other chemosynthesis-based ecosystems. highest taxon richness found diffuse venting areas may be promoted by biogenic habitat generated foundation Sclerolinum contortum . isotopic signatures community show clear influence chemosynthetic primary production foodweb. Considering novel specialised documented paper, vents AMOR should regarded as vulnerable marine ecosystems protective measures must therefore implemented, especially considering potential threat resource exploration exploitation near future.

Life in the Midwater: The Ecology of Deep Pelagic Animals

Annual Review of Marine Science, Год журнала: 2024, Номер 16(1), С. 383 - 416

Опубликована: Янв. 17, 2024

The water column of the deep ocean is dark, cold, low in food, and under crushing pressures, yet it full diverse life. Due to its enormous volume, this mesopelagic zone home some most abundant animals on planet. Rather than struggling survive, they thrive—owing a broad set adaptations for feeding, behavior, physiology. Our understanding these constrained by tools available exploring sea, but tool kit expanding along with technological advances. Each time we apply new method depths, gain surprising insights about genetics, ecology, physiology, diversity, dynamics change. These discoveries show structure within seemingly uniform habitat, limits inexhaustible resources, vulnerability impervious environment. To understand midwater need reimagine rules that govern terrestrial ecosystems. By spending more at depth—with whatever are available—we can fill knowledge gaps better link ecology environment throughout column.

Low-Cost, Deep-Sea Imaging and Analysis Tools for Deep-Sea Exploration: A Collaborative Design Study

Frontiers in Marine Science, Год журнала: 2022, Номер 9

Опубликована: Авг. 11, 2022

A minuscule fraction of the deep sea has been scientifically explored and characterized due to several constraints, including expense, inefficiency, exclusion, resulting inequitable access tools resources around world. To meet demand for understanding largest biosphere on our planet, we must accelerate pace broaden scope exploration by adding low-cost, scalable traditional suite research assets. Exploration strategies should increasingly employ collaborative, inclusive, innovative methods promote inclusion, accessibility, equity ocean discovery globally. Here, present an important step toward this new paradigm: a collaborative design study technical capacity needs equitable deep-sea exploration. The focuses opportunities challenges related data collection artificial intelligence-driven analysis. It was conducted in partnership with twenty marine professionals worldwide, covering broad representation geography, demographics, domain knowledge within space. results include set requirements low-cost imaging sensing systems automated image analysis systems. As result study, camera system called Maka Niu prototyped is being field-tested thirteen interviewees online AI-driven video platform development. We also identified six categories open implementation questions highlighting participant concerns potential trade-offs that have not yet addressed current projects but are as considerations future work. Finally, offer recommendations outline work

The current status of deep-sea mining governance at the International Seabed Authority

Marine Policy, Год журнала: 2022, Номер 147, С. 105396 - 105396

Опубликована: Ноя. 18, 2022

This article describes the current state of deep-sea mining governance in areas beyond national jurisdiction, providing an accessible overview structure and functioning International Seabed Authority (ISA), as well some background information on different instruments developed by ISA for regulation, control management. In particular, focuses way environmental considerations are currently being discussed negotiated under Draft Exploitation Regulations. Given that there no official records kept meetings, this thereby also provides a body is difficult to access.

Exposing inequities in deep-sea exploration and research: results of the 2022 Global Deep-Sea Capacity Assessment

Frontiers in Marine Science, Год журнала: 2023, Номер 10

Опубликована: Авг. 9, 2023

The 2022 Global Deep-Sea Capacity Assessment is a baseline assessment of the technical and human capacity for deep-sea exploration research in every coastal area with deep ocean worldwide. From 200 to nearly 11,000 meters below sea level, encompasses single largest—and arguably most critical—biosphere on Earth. Globally, two-thirds all exclusive economic zones combined have water depths between 2,000 6,000 meters, making this particularly critical depth range access. This study includes information 186 countries territories, analyzed by subregional, regional, income groups. data were collected through both an online survey manual research. We found that globally, 52% respondents agreed considered important their community. A third they had in-country technology conduct research, half expertise. Survey results revealed challenges worldwide are funding, access vessels, capacity. top three global opportunities training opportunities, less expensive collection technology, better analysis tools. provides necessary strategically develop, equitably implement, quantitatively measure impact development over coming years. It now possible evolution next decade, indicator progress during UN Decade Ocean Science Sustainable Development.
