BIONESS profile and plankton sample collection data for plankton samples collected off Alabama (2007-2015)

Depth-discrete plankton samples were collected during cruises off the coast of Alabama during May-August periods (2007-2015) using a Bedford Institute of Oceanography Net Environmental Sampling System (BIONESS). The BIONESS (0.25 m2 opening) was fitted with 333-µm and 202-µm mesh nets. The BIONESS can fish as many as 9 plankton nets during a given tow, though not all nets were used during every tow. Each BIONESS tow therefore will have multiple net samples associated with it. Profile data (depth, temperature, salinity) were obtained with a SBE-19+ CTD (Sea-Bird Electronics) integrated with the BIONESS data logger. Samples were collected at stations located on the 20 m and 35 m contours. Data from 2007-2012 were collected as part of the Dauphin Island Sea Lab's Fisheries Oceanography of Coastal Alabama (FOCAL) program. Data from 2013-2015 were collected with support from GoMRI. All months were not sampled due to inclement weather or gear malfunction.

本数据集的深度分层浮游生物样本采集于2007年至2015年每年5至8月的阿拉巴马州近岸航次，采用贝德福德海洋学研究所网具环境采样系统（Bedford Institute of Oceanography Net Environmental Sampling System，缩写BIONESS）完成。该BIONESS系统有效开口面积为0.25平方米，配备了孔径分别为333微米和202微米的浮游生物网。单次拖曳作业中，BIONESS最多可搭载9台浮游生物网，但并非每次拖曳都会启用全部网具，因此每一次BIONESS拖曳作业都会对应多份网采样本。同步搭载于BIONESS数据记录仪的SBE-19+型温盐深仪（Sea-Bird Electronics）获取了包括水深、温度及盐度在内的剖面数据。样本采集站位设置在水深20米和35米的等深线处。2007年至2012年的数据采集工作作为多芬岛海洋实验室阿拉巴马州近岸渔业海洋学（Fisheries Oceanography of Coastal Alabama，缩写FOCAL）项目的一部分完成。2013年至2015年的数据采集工作得到了墨西哥湾研究倡议（Gulf of Mexico Research Initiative，缩写GoMRI）的资助。由于恶劣天气或设备故障，部分采样月份未能完成数据采集。
