說明
The data all come from the JC2-2 expedition of the Nansen Legacy to the Nansen and Amundsen Basins in Aug-Sept 2021 (Fransson et al. 2022, https://doi.org/10.7557/nlrs.6413 ) where 5 stations were sampled from sea ice to seafloor. They contain carbon and nitrogen isotope values for pelagic and benthic invertebrates.

計畫資料
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.

取樣方法
Zooplankton samples were collected from WP2 net hauls. Benthic fauna were sampled from surface sediments of box cores which was sieved over 0.25 mm mesh. Due to low densities, fauna were pooled by taxon from replicate box cores per site, frozen onboard at -20 degC and later freeze-dried. Details in Kohlbach et al. (in revision with Elementa) and also refer to Nansen Legacy protocol v.10.

方法步驟描述:
- Dried faunal samples were analyzed at the Alaska Stable Isotope Lab on a Thermo Scientific Conflow IV and Delta VPlus ratio mass spectrometer. For all samples d15N values are from non-acidified samples, while d13C values are from acidified subsamples for calcifying organisms.
