Cobertura Geográfica

The data sets contains information on occurrence, counts and weights (per 11.7 diameter core) of benthic macrofauna at one locations (P8) in the Nansen Basin, one location on the Gakkel Ridge (P9) and two locations (P10, P11) in the Amundsen Basin, sampled in Aug/Sept 2021.

Dados Sobre o Projeto

The Nansen Legacy is a novel and holistic Arctic research project providing integrated scientific knowledge on the rapidly changing marine climate and ecosystem. A new knowledge base is required to facilitate a sustainable management of the northern Barents Sea and adjacent Arctic Basin through the 21st century. The Nansen Legacy unites about 280 researchers, students, and technicians from ten Norwegian research institutions. The research team includes interdisciplinary arctic marine expertise within physical, chemical, and biological oceanography, as well as geologists, modelers and underwater robotic engineers. Jointly we investigate the past, present and future climate and ecosystem of the northern Barents Sea. In total, the project has spent over 350 days at sea between 2018 and 2022, using the new Norwegian research icebreaker ‘Kronprins Haakon’ as main research platform. The ship-based sampling is complemented by the use of underwater robotics, year-round moored observing platforms and satellite-based observations. Complementary model tools are used to integrate field-based observations, and to investigate the dynamics of the physical and biological components of the northern Barents Sea climate and ecosystem at present and in the future. The Nansen Legacy is home to over 70 early career scientists, providing them with a unique collaborative community and supervision across institutions and disciplines. This gives rise to a new generation of holistic thinking Arctic research leaders. The Nansen Legacy runs for seven years (2018–2024), and is funded by the Research Council of Norway and the Norwegian Ministry of Education and Research. They provide 50% of the budget while the participating institutions contribute 50% in-kind. The total budget for the Nansen Legacy project is 740 mill. NOK.

Métodos de Amostragem

Sediment samples for analysis of macrofaunal diversity, abundance and biomass were taken from multiple 11.7 cm diameter cores inserted in 50x50 cm box cores. These cores were first used for sediment community oxygen respiration and then gently sieved completely through 250 µm for macrofaunal community estimates with cold seawater. The remaining biota was then preserved in a 4% buffered formaldehyde-seawater solution that was rose Bengal-stained. This work is part of RF3 of the Nansen Legacy project, cruise JC2-2, August/September 2021. Protocol version 9 was used (10.3.9, but smaller sieve size and different contact person).

Descrição dos passos do método:

1. In the home lab, samples were sorted to major taxa first under a stereomicroscope (partly at UiT, partly at IOPAN). Subsequently macrofauna taxa were identified to the lowest possible taxonomic level, enumerated and the weight taken. Meiofauna in the samples was identified to phylum level only. Fragments were not enumerated but weighed. Taxonomic identification my be improved for some individuals in the future.
