BIONESS profile and plankton sample collection data, cruise PTS01, northern Gulf of Mexico, October – November 2015

Depth-discrete plankton samples were collected during CONCORDE cruise PTS01 (October 28th-November 5th, 2015) 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 40 m depth contours between the Chandeleur Islands and the Alabama/Florida border to assess the horizontal and vertical distribution of plankton under low freshwater discharge conditions characteristic of the Fall.

2015年10月28日至11月5日，在CONCORDE航次PTS01执行期间，科研人员采用加拿大贝德福德海洋研究所网式环境采样系统（Bedford Institute of Oceanography Net Environmental Sampling System, BIONESS）采集分深度离散的浮游生物样本。该采样系统开口面积为0.25平方米，配备6张333微米孔径的网具与3张202微米孔径的网具。研究人员通过与BIONESS数据记录仪集成的SBE-19+型CTD（Sea-Bird Electronics）获取水深、水温、盐度等剖面数据。本次采样主要覆盖尚德勒尔群岛至阿拉巴马州与佛罗里达州边界之间的15至40米等深线区间，旨在评估秋季典型低淡水径流条件下浮游生物的水平与垂直分布格局。
