Abstract:

This dataset contains conductivity, temperature, and depth data used to monitor the inner shelf and coastal sounds of Louisiana. The data was collected on 2010-11-01, 2010-12-22, and 2011-01-20 along a cruise track running from Rigolets to the Chandeleur Islands. This dataset also includes depth-integrated samples of particle diameter in suspension using a Sequoia Laser In-Situ Scattering and Transmissometry (LISST) instrument LISST-100x type C sensor.

Purpose:

This monitoring seeks to understand the distribution of particulates and oil in coastal waters, in an attempt to identify the dominant force of transport for different type of oil reaching shallow waters near the inner shelf and coastal sounds, by monitoring the density structure in combination with optical and particulate properties within the interior Sounds and bays and near the inner shelf.

Data Parameters and Units:

Site, Latitude (decimal degrees), Longitude (decimal degrees), Conductivity (uS/cm), Density (kg/m^3), Depth (salt water, m), Density (sigma-t, kg/m^3), Descent Rate (m/s), Oxygen, SBE 43 (mg/l), Oxygen, SBE 43 (% saturation), Pressure, Strain Gauge (db), Salinity (PSU), Temperature (ITS-90, deg C), Time, Elapsed (seconds). LISST data - the filename of each file corresponds to the cruise date which was similar to other parameters collected herein (eg CTD data).- Column 1 (Column A, if opened in Excel): Lines 2-25: Sample ID. (Description: Each of the 24 sample sites in the order that were sampled (1-24) coordinates and map for which are listed in other files of this dataset). Column 2-33 (Column A-AG, if opened in Excel): Volume (mL/L) occupied by the particles in suspension for each diameter and sample. Diameters are listed in line 1 starting at 2.716 microns through 460 microns) Column 34-41 (Column AL-AP, if opened in Excel): These are summations of mass and volume to generate the statistics reported Column 42-48 (Column AQ-AW, if opened in Excel): Particle diameter statistics representing the 35th, 50th, 65th, 75th, and 95th percentile diameter (percent passing), as well as skewness and kurtosis based on a volume weighted analysis of the sample.
