Abstract:
Depth-discrete plankton samples were collected during CONCORDE cruise PTS02 (March 30th-April 10th, 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 12 and 45 m depth contours between the Chandeleur Islands and the Alabama/Florida border to assess the horizontal and vertical distribution of plankton under high freshwater discharge conditions characteristic of the Spring.

Purpose:
The intent of this dataset is to identify the station, field, and environmental conditions that were encountered during each BIONESS tow on the Spring field campaign of CONCORDE (March-April). The station and field information were recorded at the start and end of the station by field personnel on the vessel whereas the environmental data (temperature and salinity) were collected with a CTD (SBE-19+) mounted to the BIONESS system.
