BIONESS, Depth-Discrete Samples, Salinity, Temperature, Depth
Abstract:
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. Plankton data (e.g., displacement volumes, ichthyoplankton and zooplankton abundances) for BIONESS tows are provided in a separate dataset R4.x260.000:0007 (doi:10.7266/N7XP730K)

Purpose:
The intent of this dataset is to identify the station, field, and environmental conditions that were encountered during each BIONESS tow on the Fall field campaign of CONCORDE (October-November). 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.
