Size-based indicators in the deep sea

Supporting data for the paper: Mindel, B.L., Neat, F.C., Webb, T.J. &amp; Blanchard, J.L. Sized-based indicators show depth-dependent change over time in the deep sea. ICES Journal of Marine Science, DOI 10.1093/icesjms/fsx110.<br>Datasets have been summarised to enable replication of figures and analyses from this paper. Data are provided by Marine Scotland from their ongoing deepwater trawl survey. <br><br>Haul level indicators:Data to produce Fig. 2 A, B, C and Fig. 3 from the paper. Values are given at the level of the haul and include temperature, depth, mean body length, mean maximum length, LFI (proportion of biomass made up of individuals greater than 40 cm in length) and LFI60 (proportion of biomass made up of individuals greater than 60 cm in length). <br>Year level indicators:Slope of the normalised biomass spectrum for each year of the survey (as detailed in the Methods section of the paper) to produce Fig. 2D.本数据集为下述学术论文的配套支撑数据：Mindel, B.L.、Neat, F.C.、Webb, T.J. 与 Blanchard, J.L. 发表于《ICES海洋科学杂志（ICES Journal of Marine Science）》的研究《基于体型的指标揭示深海生态系统随时间的深度依赖性变化（Sized-based indicators show depth-dependent change over time in the deep sea）》，DOI：10.1093/icesjms/fsx110。 本数据集已完成标准化整理，可用于复现该论文中的全部图表与分析流程。数据由苏格兰海洋局（Marine Scotland）基于其持续开展的深水拖网调查项目提供。 拖网站位层级指标：包含用于复现论文中图2A、2B、2C及图3的相关数据。数据以单次拖网作业站位为统计单位，涵盖水温、水深、平均体长、平均最大体长、LFI（体长大于40cm的个体生物量占比）以及LFI60（体长大于60cm的个体生物量占比）。 年份层级指标：包含用于复现论文中图2D的相关数据，即该调查各年份的归一化生物量谱斜率（具体细节详见论文方法部分）。
