HEADERS CURRENTLY SUPPORTED BY SeaBASS (last updated 06.16.2000)

~~~~~~~~~~~~~~
/investigators
Principal investigator is listed first, followed by any associate investigators.

~~~~~~~~~~~~~
/affiliations
A list of affiliations (e.g. university, laboratory) for each investigator.

~~~~~~~~
/contact
An email address for one of the investigators or point of contact for the data 
file.

~~~~~~~~~~~
/experiment
The name of the long~term research project (e.g. CALCOFI, CARIACO, EcoHAB, BBOP,
BTM).

~~~~~~~
/cruise
The name of the specific cruise (or subset of the experiment) where the data in
the file were collected (e.g. cal9802, car48, BBOP98, dep12).

~~~~~~~~
/station
The name of the station or deployment where data in the file were collected.

~~~~~~~~~~~~~~~
/data_file_name
The current name of the data file.

~~~~~~~~~~~~~~~~~~~
/original_file_name
(OPTIONAL) The original name of the data file, if different from the current 
/data_file_name. Originally designed to reference the investigators' working 
data file before SeaBASS headers were added.

~~~~~~~~~~
/documents
Refers to cruise reports, station logs, digital images, and other associated 
documentation that provide additional information about the experiment and 
cruise.

~~~~~~~~~~~~~~~~~~
/calibration_files
Refers to supplementary files containing coefficients and techniques used to 
calibrate the instruments used in data collection.

~~~~~~~~~~
/data_type
Describes the general collection method for the data. Accepted values include: 
cast for vertical profiles (e.g. optical packages, CTD), flow_thru for 
continuous data (e.g. shipboard, underway flow through systems), above_water 
for above surface radiometry data (e.g. ASD, SIMBAD, Satlantic SAS), sunphoto 
for sunphotometry data (e.g. MicroTops, PREDE), mooring for moored and buoy 
data, drifter for drifter and drogue data, scan for discrete hyperspectral 
measurements, and pigment for laboratory measured pigment data (e.g. 
fluorometry, sspectrophotometry, HPLC).

~~~~~~~~~~~~
/data_status
The condition, or status, of the data file. The value preliminary is used when 
the data are new and the investigator intends to analyze the data further. The 
value update indicates the data are being resubmitted and informs the SIMBIOS 
Project that an additional resubmission will occur in the future. The value 
final is used when the investigator has no intention of revisiting the data set.

~~~~~~~~~~~
/parameters
(OPTIONAL) A generic listing of field data included in the data file. Each 
field should be listed in parameters, but they need not be wavelength specific. 
For example, '/parameters=Lu,Ed,CHL,Wt' would be appropriate for a file with 
upwelling radiance, downwelling irradiance, fluorometric chlorophyll~a, and 
water temperature.

~~~~~~~~~~~
/start_date
The earliest date data in the file were collected (in YYYYMMDD). Example: 
/start_date=19990110.

~~~~~~~~~
/end_date
The latest date data in the file were collected (in YYYYMMDD). Example: 
/end_date=19990211.

~~~~~~~~~~~
/start_time
The earliest time of day data in the file were collected (in HH:MM:SS and 
Greenwich Mean Time). This does not necessarily correspond with the time data 
collection began. Requires [GMT] trailer. Example: /start_time=02:45:30[GMT].

~~~~~~~~~
/end_time
The latest time of data data in the file were collected (in HH:MM:SS and 
Greenwich Mean Time). This does not necessarily correspond with the time data 
collection ended. Requires [GMT] trailer. Example: /end_time=02:56:20[GMT].

~~~~~~~~~~~~~~~
/north_latitude
The farthest north data in the file were collected (in degrees). Requires [DEG] 
trailer. Example: /north_latitude=45.223[DEG].

~~~~~~~~~~~~~~~
/south_latitude
The farthest south data in the file were collected (in degrees). Requires [DEG] 
trailer. Example: /south_latitude=31.884[DEG].

~~~~~~~~~~~~~~~
/east_longitude
The farthest east data in the file were collected (in degrees). Requires [DEG] 
trailer. Example: /east_longitude=-65.225[DEG].

~~~~~~~~~~~~~~~
/west_longitude
The farthes west data in the file were collected (in degrees). Requires [DEG] 
trailer. Example: /west_longitude=-83.117[DEG].

~~~~~~~~~~~~~~
/cloud_percent
Percent cloud cover for the entire sky (e.g. 0 = no clouds, 100 = completely 
overcast).

~~~~~~~~~~~~~~~~~~
/measurement_depth
If the data in the file were collected at a discrete depth, this is that depth 
(in meters). Applicable for bottle samples, and buoys and moored radiometers.

~~~~~~~~~~~~~
/secchi_depth
The secchi depth at the station where the data were collected (in meters).

~~~~~~~~~~~~
/water_depth
The water depth at the station where the data were collected (in meters).

~~~~~~~~~~~~
/wave_height
The wave height at the station where the data were collected (in meters).

~~~~~~~~~~~
/wind_speed
The wind speed at the station where the data were collected (in meters per 
second).

~~~~~~~~~~
! COMMENTS
A space for additional comments. Common comments include additional ancillary 
information about the data file, sea and sky states, difficulties encountered 
during data collection, methods of data collection, instruments used, and a 
description of nonstandard SeaBASS field names included in the data file.

~~~~~~~~
/missing
Refers to the NULL value used as a numeric placeholder for any missing data in 
the data file. Note that each row of data must contain the same number of 
columns as defined in the /fields and /units headers.

~~~~~~~~~~
/delimiter
Indicates how the columns of data are delimited. Accepted delimiters include 
tab, space, and comma. Only a single (1) delimiter is permitted per data file.

~~~~~~~
/fields
A list of the fieldnames for each column of data included in the data file. 
Each entry describes the data in a single (1) column, and every column must 
have an entry.

~~~~~~
/units
A list of the units for each column of data included in the data file. Every 
value in /fields must have an appropriate value listed here.
