Dataset: SeaSoar CTD observations from R/V Oceanus cruises OC340 and OC343 in the Gulf of Maine and Georges Bank in 1999 as part of the U.S. GLOBEC program (GB project)

The seasoar is a towed, undulating vehicle which records CTD and other data. The system records SeaBird CTD data at 24 hz, and it had other sensors on the A/D channels. The seasoar gets towed along different tracklines to map out various survey areas. Each time the seasoar is deployed and recovered is one "tow", and each of the cruises have a number of tows.

  These are flat files, with data every 1-sec for each tow.  The tows are 
  numbered sequentialy (tow1, tow2, etc).

Notes:
1. There are two fields for different fluorometers: flvolt (aka FL-1) is from a WetLabs Wetstar fluorometer, while flvolt_2 (aka FL-2) is from a WetLabs FlashPAK fluorometer.

2. Original field name is shown in parenthesis in the "Description" column.

3. There were some problems in the data fields whenever the lat/lon were interpolated for lack of GPS observations. The OC343 data files were replaced on-line with the reprocessed files October 16, 2000.
