Inventory of Gulf oceanic fauna data including species, weight, and measurements. Cruises DP01 May 1-8, 2015 and DP02 August 9-21, 2015 R/V on the Point Sur in the Northern Gulf of Mexico

This data set includes the biological and environmental data for all of the species collected during the DP01 (May 2015) and DP02 cruises (August 2015). The main gear type used was a 10-m2 Multiple Opening Closing Net and Environmental Sensing System (MOCNESS). The MOCNESS was fitted with 6 nets which were opened according to the following depth scheme: net 0 from the surface to 1500m, net 1 from 1500-1200m, net 2 from 1200-1000m, net 3 from 1000-600m, net 4 from 600-200m, and net 5 from 200m to the surface. Two trawls were conducted at each station sampled to capture diel vertical migration information; one during daylight hours between 9am-2:30pm CDT, and the other at 9pm-2:30am CDT. A dipnet and a neuston net were also used to collect sargassum and other animals from the surface for genetic and stable isotope analyses. A table of the taxonomic hierarchy used in the nekton database will be included with references to those scientific names recently updated which are not yet reflected by the Integrated Taxonomic Information System (www.itis.gov). The MOCNESS sensor data and ship data collected during cruise DP01 are available in GRIIDC datasets R4.x257.226:0002 and R4.x257.226:0003 respectively and for cruise DP02 in GRIIDC datasets R4.x257.226:0006 and R4.x257.226:0011 respectively.

本数据集涵盖了DP01航次（2015年5月）与DP02航次（2015年8月）所采集的全部物种的生物与环境数据。本次采样采用的主要设备为10平方米多网开闭环境感知系统（Multiple Opening Closing Net and Environmental Sensing System，MOCNESS），该系统搭载6张采样网，按以下深度分层开启作业：网0作业层为表层至1500米，网1为1500~1200米，网2为1200~1000米，网3为1000~600米，网4为600~200米，网5为200米至表层。每个采样站位均开展两次拖网作业以获取昼夜垂直迁移相关数据：一次为中部夏令时间（CDT）上午9时至下午2时30分的日间拖网，另一次为当日晚间9时至次日凌晨2时30分的夜间拖网。此外，研究团队还使用抄网（dipnet）与浮拖网（neuston net）采集表层马尾藻及其他动物样本，用于遗传学与稳定同位素分析。本数据集将附带自游生物（nekton）数据库所采用的分类层级表，并标注了近期更新但尚未被综合分类信息系统（Integrated Taxonomic Information System，ITIS，官网：www.itis.gov）收录的物种学名参考资料。DP01航次采集的MOCNESS传感器数据与船舶配套数据，分别可在GRIIDC数据集R4.x257.226:0002与R4.x257.226:0003中获取；DP02航次的对应数据则分别存储于GRIIDC数据集R4.x257.226:0006与R4.x257.226:0011中。
