BIONESS profile and plankton sample collection data, cruise PTS03, northern Gulf of Mexico, July 2016

Depth-discrete plankton samples were collected during CONCORDE cruise PTS03 (July 23rd-July 30th, 2016) using a Bedford Institute of Oceanography Net Environmental Sampling System (BIONESS). The BIONESS (0.25 m2 opening) was fitted with six 333-µm mesh nets and three 202-µm mesh nets. Profile data (depth, temperature, salinity) were obtained with a SBE-19+ CTD (Sea-Bird Electronics) integrated with the BIONESS data logger. Samples were collected generally between the 15 and 32 m depth contours between the Chandeleur Islands and the Alabama/Florida border to assess the horizontal and vertical distribution of plankton under variable freshwater discharge and low dissolved oxygen conditions characteristic of the summer. Related data from this cruise can be found in GRIIDC datasets: R4.x260.000:0009 (zooplankton and ichthyoplankton), R4.x260.000:0028 (mesozooplankton dry weight), R4.x260.000:0006 (Neuston collection data), and R4.x260.000:0036 (mesozooplankton gut fluorescence).本数据集包含2016年7月23日至7月30日CONCORDE航次PTS03期间采集的分层浮游生物样品，采样采用贝德福德海洋研究所网环境采样系统（Bedford Institute of Oceanography Net Environmental Sampling System，简称BIONESS）。该BIONESS采样网的有效开口面积为0.25平方米，配备6张孔径333微米的网具与3张孔径202微米的网具。同步搭载的SBE-19+型温盐深剖面仪（Conductivity Temperature Depth，CTD，Sea-Bird Electronics公司生产）与BIONESS的数据记录仪集成，获取了包括水深、水温、盐度在内的剖面数据。本次采样区域大致覆盖尚德勒尔群岛至阿拉巴马州/佛罗里达州州界之间的15至32米等深线海域，旨在评估夏季典型的可变淡水径流与低溶解氧环境下，浮游生物的水平与垂直分布特征。本航次的相关关联数据可于GRIIDC数据库中查询，具体数据集编号为：R4.x260.000:0009（浮游动物与鱼卵仔稚鱼数据）、R4.x260.000:0028（中型浮游动物干重数据）、R4.x260.000:0006（漂浮生物采集数据）、R4.x260.000:0036（中型浮游动物肠道荧光数据）。
