CTD, Short-lived radioisotope, sediment sample location data, and other sediment data types collected aboard R/V Weatherbird cruise WB-0816 in the Gulf of Mexico from 2016-08-05 to 2016-09-09 (NCEI Accession 0226799)

1. GRIIDC dataset R4.x267.179:0026; CTD data and sediment sample location data:
1.1 CTD data - Depth [salt water depth, m]; Temperature [deg C]; Conductivity [S/m]; Salinity [PSU]; Oxygen Saturation [umol/Kg]; Oxygen, SBE 43 [umol/Kg]; Fluorescence, WET Labs CDOM [mg/m^3]; Fluorescence, WET Labs ECO-AFL/FL [mg/m^3]; Turbidity, WET Labs ECO [NTU]; Density [density, Kg/m^3]; Average Sound Velocity [Chen-Millero, m/s]; PAR/Irradiance, Biospherical/Licor; Sound Velocity [Chen-Millero, m/s]; Altimeter [m]; Latitude [deg]; Longitude [deg].

CTD files are named based on the station where the data were collected or based on a pre-cruise equipment test. If the file name is based on the station where the data were collected, then the naming convention is - <cruise-station-date-cast> (if there are more than casts at the station).

For example, file WB0816SIXW75008152016cast1 indicates that the cruise = WB0816, where the station = SIXW750, the date = 08152016 and the cast = cast1.

1.2 Sediment sample location data - Site # [station location, ID]; Collection Date [mm/dd/yyyy]; Latitude [degree minute]; Longitude [degree minute]; Water Depth [meter]; Core Sample Label [text]; Allocation [text]; Length [mm].

2. GRIIDC dataset R4.x267.000:0007; Bulk density/porewater data:
Latitude and longitude of core site (decimal degrees), water depth of core site (m), core collection date (mm/dd/yyyy), site identification (ID), core identification (id), top depth of interval (mm), bottom depth of interval (mm), average depth of interval (mm), sediment wet weight (g), sediment dry weight (g), sample volume (cm3), bulk density (g/cm3), porewater (%), laboratory/facility analysis was performed at. Bulk density was calculated using sediment dry weight (g) and sample volume (cm3). Blank cell denotes analysis not performed for the interval, no data generated.
