Size and otolith morphometrics of Notoscopelus kroyeri collected during IESSNS south of Iceland in July 2020 and 2021

This dataset contains biological measurements of 338 individuals of the North Atlantic myctophid Notoscopelus kroyeri (Krøyer's lantern fish). Individuals were collected opportunistically as bycatch in pelagic trawls (surface and deep) during the Icelandic portion of the International Ecosystem Summer Survey of Nordic Seas (IESSNS) conducted in south Icelandic waters and the Irminger Sea in July 2020 and south and west Icelandic waters in 2021. Frozen samples were processed on land in 2022 from twelve trawl stations located in four IESSNS strata regions (5, 6,11, and 12). Further details on the trawl methodology, sampling and associated environmental variables can be found in related to references and two survey reports (Ólafsdóttir and Kennedy 2020, Ólafsdóttir et al. 2022). Observations include multiple length and weight measurements, as well as otolith morphometrics, including otolith length, width and area. […]

本数据集收录了北大西洋鲀科鱼类 Notoscopelus kroyeri（克洛伊氏灯笼鱼）的338个个体的生物测量数据。这些个体在2020年7月于南冰岛水域及伊尔明格尔海以及2021年南冰岛及西冰岛水域进行的国际生态系统夏季调查北欧海域（IESSNS）期间，作为远洋拖网作业的附带捕获物而采集。2022年，从位于IESSNS四个层区（5、6、11和12）的十二个拖网站采集的冷冻样本在陆地上进行处理。关于拖网方法、采样以及相关环境变量的更详细信息，可参考相关参考文献和两份调查报告（Olafsdottir和Kennedy 2020，Olafsdottir等人2022）。观测数据包括多个长度和重量测量值，以及耳石形态学指标，包括耳石长度、宽度和面积。
