計畫資料

The Arctic Marine Biodiversity Observing Network (AMBON) project is part of the US MBON program. The Arctic Marine Biodiversity Observing Network (AMBON) is designed to provide high-quality biodiversity data from the Arctic Chukchi Sea across trophic levels, from microbes to whales. Here, data on the epifainal communities are provided

研究區域描述 The northern Bering Sea and the Chukchi Sea are shallow Arctic shelf systems in US waters. They are characterized by high nutrient inputs, which makes them very productive. These Arctic Ocean marginal seas are among the fastest-warming regions in the world, with ecosystem changes across all trophic levels that carry repercussions to ecosystem function.

取樣方法

Samples were taken with a plumb-staff beam trawl with a 2.26-m opening and a 7-mm mesh net with a 4-mm cod end liner. Tows were generally between 3-5 min at a tow speed of 1.5 knots.

研究範圍 Epibenthic data were collected in early fall 2024 in the northern Bering Sea and Chukchi Sea

方法步驟描述:

  1. Once on deck, the catch was sorted into major taxa and weighed and counted on board. Based on the trawled area, overall biomass and abundance as catch per unit effort (CPUE) were determined in g wet weight 1000 m-2 and number of individuals 1000 m-2, respectively.

額外的詮釋資料

致謝 These data were collected as part of the Arctic Marine Biodiversity Observing Network (AMBON), a member of the Marine Biodiversity Observing Network (MBON). The work was funded through The National Aeronautics and Space Administration (NASA, 80NSSC22K1780) and the Office of Naval Research (ONR, N00014-22-1-2792).
Introduction Epibenthic communities play important roles in Arctic shelf systems based on their high biomass that is critical in pelagic-benthic coupling, mineralization of organic matter, and as a food source for many higher trophic levels such as fish, whales, seals, walrus, and humans. 
目的 This dataset provides quantitative biomass and abundance data for a wide range of epifaunal taxa collected with a beam trawl. Taxa are mostly identified to species or genus level but many also identified to higher taxonomic levels. These data collected in 2024 can be compared to other data from previous of later years for temporal patterns.
