Compilation of new data on stable nitrogen and carbon isotope ratios of marine biota from the subarctic and temperate Atlantic, and western Mediterranean Sea

Isotopic data are valuable to investigate species interactions and food web structure. This file compiles δ13C and δ15N values of various marine taxa; most of data correspond to mesopelagic fish, but mesopelagic cephalopods, decapods and zooplankton, and cetaceans are also represented. This dataset follows a previous data file presented in Silva et al. (2022b) (https://doi.pangaea.de/10.1594/PANGAEA.945917) and maintains the same layout. A total of 1045 records are included, of which 612 correspond to mesopelagic fish (55 species), 18 to non-mesopelagic fish (1 species), 168 to decapods (7 species), 68 to marine mammals (12 species), 5 to Cephalopoda (2 species) and 174 to zooplankton (14 taxa). Data are available for the subarctic and temperate Atlantic, the northeast Atlantic (off the Iberian Peninsula, Azores, and Bay of Biscay), and the Western Mediterranean. Samples come from years 2002 to 2021, and expand to all seasons. […]

同位素数据对于研究物种相互作用和食物网结构具有重要意义。本文件汇编了多种海洋生物的δ13C和δ15N值；其中大部分数据对应于中层海洋鱼类，但中层海洋头足类、甲壳类动物、浮游动物以及鲸类亦有所涉及。该数据集遵循Silva等（2022b）先前提出的文件格式（https://doi.pangaea.de/10.1594/PANGAEA.945917），并保持相同的布局。共计包含1045条记录，其中612条对应中层海洋鱼类（55种），18条对应非中层海洋鱼类（1种），168条对应甲壳类动物（7种），68条对应海洋哺乳动物（12种），5条对应头足类（2种）以及174条对应浮游动物（14个类群）。数据涵盖了亚北极和温带大西洋、东北大西洋（伊比利亚半岛、亚速尔群岛和比斯开湾附近）以及西地中海。样本采集自2002年至2021年，并涵盖所有季节。
