Longline trap data collected during R/V Apalachee cruise AP-1312 in the Northern Gulf of Mexico from 2013-10-08 to 2013-10-15

This dataset reports species caught using longline and trap sets during the R/V Apalachee cruise from October 8-15, 2013. Species data includes species name, sex, weight, length, and maturity state, if available. It also report if samples were collected from individuals for other analyses, though the results of those analyses are not reported here. Information about the sets include bait used, gear, effort, and sea state. Additional files in the dataset report pressure and temperature data collected during longline trapping activities. The overall objectives of this research include using large chevron traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes associated with the eastern and western walls of DeSoto Canyon and the adjacent continental slope (75-2000 m deep) and collecting specimens and samples (including curation of new species) to aid in resolving phylogenetic uncertainties and understanding life history traits in collected taxa.本数据集记录了2013年10月8日至15日阿巴拉契号研究船（R/V Apalachee）航次中，通过延绳钓与陷阱装置捕获的物种信息。物种数据涵盖物种名称、性别、体重、体长及成熟状态（若可获取）。数据集同时记录了是否从个体采集了用于其他分析的样本，尽管此处未披露此类分析的结果。作业相关信息包括所用饵料、渔具、捕捞努力量及海况。数据集中的附加文件记录了延绳钓与陷阱作业期间采集的压强与温度数据。本研究的总体目标包括两部分：一是利用大型人字形陷阱与底层延绳钓，描述并分析德索托峡谷（DeSoto Canyon）东西侧壁及相邻大陆坡（水深75~2000米）区域的底层鱼类物种组合与相对丰度差异；二是采集标本与样本（包括新物种的标本整理），以助力解决系统发育学上的不确定性问题，并解析所采集类群的生活史特征。
