SOLOPC - CTD Profile Data
SOLOPC File Number, Date, Time, Lat, Lon from data file header record
Depth, Temperature, Salinity Profile

SOLOPC Specs (.pdf)

Methods & Sampling

Dataset acquisition description

Data are from standard SOLO-I CTD on the SOLOPC. The SOLOPC is described in Checkley, D.M., R.E. Davis, A.W. Herman, G.A. Jackson, B. Beanlands and L.A. Regier (2008). Assessing plankton and other particles in situ with the SOLOPC. Limnology and Oceanography 53(5): 2123-2136.

Each original file contains three record types:
G 7 19 Apr 2013 1:50 +32 59.40 -117 53.22
Record type (GPS) – profile number – date – time – latitude – longitude

D 7 94 npts
Record type (data amount) – profile number – number of samples

p 7 4.7 16.006 33.541
Record type (CTD data) – profile number – depth (m) – temperature (°C) - salinity

Deployment-specific acquisition description

SOLOPC 2930 and 2931 were deployed during NH1307 and allowed to drift, profile, and sample, during which time CTD and LOPC data were acquired.

Data Processing Description

Dataset Processing Description

The CTD data were archived on the SOLOPC in hex format. The only processing done was to convert the hex to ascii.

Each original file contains three record types:
G 7 19 Apr 2013 1:50 +32 59.40 -117 53.22
Record type (GPS) – profile number – date – time – latitude – longitude

D 7 94 npts
Record type (data amount) – profile number – number of samples

p 7 4.7 16.006 33.541
Record type (CTD data) – profile number – depth (m) – temperature (°C) - salinity

BCO-DMO Processing/Edits
- Generated from SOLOPC CTD data (GK*_txt/ctd_log_*.txt files) contributed by Jessica Forrest-Baldini and David Checkley
- Awk routine "NewHorizon_SOLOPC_CTDlog_2_BCODMO.awk" generated to convert .txt files to bco-dmo formatted files
- Spaces converted to tabs
- BCO-DMO compatible parameter header generated
- File number, Date, Time, Latitude, Longitude extracted from data file header record
- ISO Date/Time Generated
- Date formatted to YYYYMMDD
- Time formatted to HHMM
- Lat deg, decimal minutes converted to decimal degrees
- Lon deg, decimal minutes converted to decimal degrees
- A few (<10) spurious longitude values (signed positive) corrected to negative for West Longitude
