CTD Data 2010

Listed in NASA Earthdata CMR

This data set contains the raw .hex files and the .cnv from CTD casts conducted near Barrow, AK from August 21 - September 8, 2010.

Description

Details of the latitude, longitude, date, and time are listed in the event log that is archived at this site. Date, time, position, bottom depth, and project sample line also are listed in each file.

Each CTD file is named sequentially; corresponding station numbers are listed in the event log. No CTD data were recorded at stations 45 and 46 because of battery failure so CTD files 45 and 46 are missing from the sequence. Data were collected from the R/V Annika Marie using a SeaBird 19+ conductivity-temperature-depth (CTD) sensor equipped with a Wetlabs WetStar WS3S fluorometer and Biospherical Instrument Inc.

Model QSP2300 PAR/irradiance sensor sensor. No post-processing of the data was done. Fluorescence is reported as mg/m3 chlorophyll a, with conversion from volts according to factory calibrations.

These values were ground-truthed to extracted chlorophyll from samples collected using Niskin bottles. The reported chlorophyll a values in the CTD files need to be corrected according to the equation: Y=0.1334X +0.1437 Where “X” is the value from the WetLabs Fluorometer and “Y” is the corrected value in mg/m3. The files have been zipped into two files for ease.

The .con file used by SeaSoft also is included and is zipped into each of the files.
