Purpose:

Establish spatial variability of exchange flows and study exchange processes at Barataria Bay inlets.

Folder/file naming conventions: The folder "ADCP" contains 5 sub-folders and these folders are named as "Inlet0x" where x is the inlet number (n = 1, 2, 3, 4, 5, 6). The data for inlets 5 and 6 are combined in folder Inlet06. Each sub-folder contains ascii files named as "Inlet0n_00x_ASC.TXT", where x is numbering the files in consecutive order. Missing numbers correspond to files created while the instrument was not in the water. The folder "towed_CT" contains 3 text files, whose names reflect the dates of data collection. The dataset includes a readme file.

Instruments:

The data were collected from two towed instruments, an Acoustic Doppler Current Profiler (towed Teledyne 1200 kHz Workhorse ADCP) and a Conductivity-Temperature (Seabird SBE37) sensor, from a survey across 6 inlets along Barataria Bay.
