Zooplankton abundance and distribution from the middle corridor and mixing array region of the Point Sur (PTS01) cruise track, northern Gulf of Mexico, October-November 2015

Depth-discrete and surface plankton samples were collected during CONCORDE cruise PTS01 (October 28th-November 5th, 2015) using two gear types: a Bedford Institute of Oceanography Net Environmental Sampling System (BIONESS) and a Neuston. The BIONESS (0.25 m2 opening) is a depth-discrete sampler that was fitted with 333-µm mesh nets and 202-µm mesh nets and the Neuston (1 x 2 m frame) was fitted with a 505-µm mesh net that sampled at the air-sea interface. Biological 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, species composition, and abundance of zooplankton and ichthyoplankton under low freshwater discharge conditions characteristic of the Fall.

本数据集的分层与表层浮游生物样品采自2015年10月28日至11月5日执行的CONCORDE航次PTS01，共采用两类采样装置：贝德福德海洋研究所网环境采样系统（Bedford Institute of Oceanography Net Environmental Sampling System，BIONESS）与浮表采样网（Neuston）。其中，BIONESS（开口面积0.25 m²）为分层采样器，搭载了333微米与202微米网目的网具；浮表采样网（框架尺寸1×2 m）配备505微米网目的网具，用于采集气海界面处的样品。生物样品的采集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米至40米等深线海域，旨在评估秋季典型低淡水径流量条件下，浮游动物与鱼类浮游生物的水平、垂直分布特征，物种组成及丰度。
