Water_Col_Profile_Data

This is the logical folder where the raw data was written at the time of file acquisition

These are the output variables selected for the .MRK file. Scan is always supplied by default. Typical protocol also calls for Depth to be included , denoted by depSM

See Abbreviation Table below for all possible selection option

Indicates the time in UTC when the mark button was pressed and its sequence number for the given cast

Data elements associated with the 1st mark. Values correspond to variable list shown on Line 2. The 1st mark indicates when the cast began and should show the surface depth associated with the cast

Indicates the time in UTC when the mark button was pressed and its sequence number for the given cast

Data elements associated with the 2ndmark. Values correspond to variable list shown on Line 2. The 2nd mark typically indicates when the cast reached its maximum sampling depth. NOTE- the max sampling depth may not be the same as the station depth

Indicates the time in UTC when the mark button was pressed and its sequence number for the given cast

Data elements associated with the 3RD mark. Values correspond to variable list shown on Line 2. The 3rd mark typically indicates when the cast reached its midpoint sampling depth on the upcast.

Indicates the time in UTC when the mark button was pressed and its sequence number for the given cast

Data elements associated with the 4th mark. Values correspond to variable list shown on Line 2. The 4th mark typically indicates when the cast reached the surface sampling depth on the upcast

Scan Number Soak Scans = 24 Default scans per second

Depth, Saltwater in Meters

Primary Salinity Value in PPT (parts per thousand)

Secondary Salinity Value in PPT (parts per thousand)

Primary Dissolved Oxygen in mg/l

Secondary Dissolved Oxygen in mg/l

Fluorescence value from WetStar fluorometer

Transmissivity value from C-Star transmissiometer

Tells the user what type of profiler, or CTD, generated the data

Shows the original path the raw files were generated in at the time of data collection

Indicates the version of SEASAVE software used to collect the data file

The serial number of the PRIMARY temperature sensor associated with the cast. Value is used for quality assurance during both playback and processing of data as this value should match the serial number in the configuration file associated with the data. If the values do not match, data cannot be reviewed or processed

The serial number of the PRIMARY conductivity sensor associated with the cast. Value is used for quality assurance during both playback and processing of data as this value should match the serial number in the configuration file associated with the data. If the values do not match, data cannot be reviewed or processed

Value is used by both SEASAVE and SBE Data Processing as a checksum for each row of data written to the .DAT or .HEX output file

Indicates the number of auxiliary sensors data was collected for during the cast. Auxiliary sensors include oxygen sensors, fluorometers, transmissometers, altimeters, PAR , and backscatterance sensors

Indicates whether averaging of the data took place within the Deck Unit. A value of 1 indicates each output scan was passed to the data file with no averaging, values above 1 indicate how many scans were averaged into each row of data

Date and time of the cast in UTC

Latitude as read from GPS feed at the start of data acquisition

Longitude as read from GPS feed at the start of data acquisition

Time and Date as read from GPS feed at the start of data acquisition

Tells user how the NMEA position data is handled in relation to each scan line of data.

The cruise the cast was conducted on

** indicates entry was prompted for as part of the Header Form entry at the time of collection

The Pascagoula Station Number where the cast was conducted

** indicates entry was prompted for as part of the Header Form entry at the time of collection

Indicates the sequential cast number for CTD Data collected at a given station. If omitted, the user should assume a default entry of 01 for a cast number

** indicates entry was prompted for as part of the Header Form entry at the time of collection

Indicates the Latitude position as observed by the CTD operator. Entry is used as a backup for the NMEA Latitude in case of NMEA failure. ** indicates entry was prompted for as part of the Header Form entry at the time of collection

The SEAMAP Station Number at which the cast was collected. If the location was not considered SEAMAP, no information will follow the : .** indicates entry was prompted for as part of the Header Form entry at the time of collection

The initials of the person running the SEASAVE software and coordinating the CTD operation at the time of data collection. ** indicates entry was prompted for as part of the Header Form entry at the time of collection

Depth, surface to bottom, in meters of the location the cast was conducted

Confirmation of the time the cast began in UTC – only present in files collected beyond 2012

Indicates the logical end of the header file
