Registros de Dados
Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 19 registros.
Também existem 2 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Dados Sobre o Projeto
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

| Descrição da Área de Estudo | 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. |

Métodos de Amostragem
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.
| Área de Estudo | Epibenthic data were collected in early fall 2023 in the northern Bering Sea and Chukchi Sea |
|---|
Descrição dos passos do método:
- 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.

| 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. |
| Propósito | 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 2023 can be compared to other data from previous of later years for temporal patterns. |
