Required Headers

The following headers are requird to be included in every SeaBASS file.

investigators

required

The contributors of the data file. The Principal Investigator (PI) is listed first, followed by any associate investigators, analysts, technicians, and students, etc. (comma-separated, no spaces).

 

affiliations

required

A list of affiliations (i.e., university, institution, or laboratory, etc.) whose number and ordering should match the entry or entries in the investigators header (comma-separated, no spaces).

 

contact

required

An email address for at least one of the investigators or point of contact for the data file. Multiple email addresses may be listed comma-separated, no spaces.

 

experiment

required

The name of the over-arching, long-term research project or funding program. Experiment names are used to generate a dataset-specific DOI and, generally, will contain multiple cruises or deployments and encompass data spanning multiple months or years. The Experiment name should be an acronym or short name, typically limited to maximum of 25 characters (no spaces). Please be consistent with a consensus-selected name if data from the project are being submitted by multiple different investigators.

For example: CalCOFI, CARIACO, EcoHAB, BBOP, BTM

 

cruise

required

The name of the specific cruise (or deployment, or subset of the experiment) where the data in the file were collected. If possible, do not exceed a meximum length of 25 characters (no spaces). Please be consistent and use a consensus-selected name if data from the same cruise are being submitted by multiple different investigators.

Various example include: cal9802, car48, bats143, dep12, EXPORTSNP.

 

station

required (or optional, if station appears in /fields= list)

The name of the station or deployment where data in the file were obtained. If the data file contains measurements from multiple stations, use the value NA and include station as a column in your data matrix. NA may also be used if the data were not assigned station names.

 

data_file_name

required

The current name of the data file (i.e., a self-reference).

 

documents

required

A comma-separated list (no spaces) naming ancillary files such as cruise reports, station logs, digital images, and other associated documentation that are part of the dataset submission (provided in the relevant documents directory) and provide additional information about the experiment and cruise. Every SeaBASS submission must be accompanied by an instrumentation-methods-calibration report that describes methods: the instruments used, how they were calibrated and how data were collected and processed. Include any required checklists.

 

See User Resources for more information.

data_type

required

Data_type is a single keyword label that describes the general contents of the data file. This is typically the collection method or platform, but a few keywords are more specific to measurement type (e.g., pigment). Accepted values are restricted to the following:

 

  • 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)
  • scan for discrete hyperspectral measurements (e.g., spectrophotometrically derived absorption)
  • pigment for laboratory measured pigment data (e.g. fluorometry, spectrophotometry, HPLC)
  • bottle (general category) for any other types of measurements from water samples collected at discrete depths (e.g. nutrients)
  • mooring for moored and buoy data
  • drifter for drifter and drogue data

Other accepted (but less common in SeaBASS) values include:

 

  • airborne for measurements made via an aircraft
  • auv for measurements made by an autonomous underwater vehicle (auv)
  • diver for measurements made by a diver
  • experimental for measurements that have a non-geospatial aspect (e.g., incubations, other special laboratory measurements, etc.)
  • lidar for lidar and other active remote-sensing measurements (e.g. MPL)
  • net_tow for measurements captured via net (e.g., zooplankton via MOCNESS)
  • sediment_trap for measurements from a sediment trap platform
  • sunphoto for sunphotometry data (e.g. MicroTops, PREDE)
  • taxonomy for data whose purpose is the classification or annotation of phytoplankton, zooplankton, or other marine groups

 

calibration_files

required

A comma-separated list (no spaces) of supplementary file names containing coefficients and techniques used to calibrate the instruments used in data collection. The named files can be found within the relevant documents folder accompanying the submitted data files.

start_date

required

The earliest date data in the file were collected (in YYYYMMDD).


For example, a start date of March 14, 2001 would be written as /start_date=20010314

 

end_date

required

The latest date data in the file were collected (in YYYYMMDD).


For example, an end date of March 14, 2001 would be written as /end_date=20010314

 

start_time

required

The earliest time of day measurements were collected during the start_date in the file (in HH:MM:SS). Times are in Greenwich Mean Time. This header requires a [GMT] trailer.


For example: /start_time=12:30:00[GMT]

 

end_time

required

The latest time of day data data were collected during the end_date in the file (in HH:MM:SS). Times are in Greenwich Mean Time. This header requires a [GMT] trailer.


For example: /end_time=13:30:00[GMT]

 

north_latitude

required

The farthest north data in the file were collected (in decimal degrees). This header requires a [DEG] trailer. Latitudes south of the equator are negative.


For example: /north_latitude=42.750[DEG]

 

south_latitude

required

The farthest south data in the file were collected (in decimal degrees). This header requires a [DEG] trailer. Latitudes south of the equator are negative.


For example: /south_latitude=36.500[DEG]

 

east_longitude

required

The farthest east data in the file were collected (in decimal degrees). This header requires a [DEG] trailer. Longitudes west of the Prime Meridian are negative.


For example: /east_longitude=-68.500[DEG]

 

west_longitude

required

The farthest west data in the file were collected (in decimal degrees). This header requires a [DEG] trailer. Longitudes west of the Prime Meridian are negative.


For example: /west_longitude=-85.750[DEG]

 

water_depth

required

The water (bottom) depth at the station where the data were collected (in meters). Use the value NA if water depth was unknown or if the file contains data from different bottom depths.

 

missing

required

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. Only one (1) missing value is allowed per file. This value MUST be non-zero. A common choice is -9999 or some other negative number large enough to never be accidentally confused with valid measurements. If your file includes below_detection_limit or above_detection_limit values, use different NULL values for each.

delimiter

required

Indicates how the columns of data are delimited. Accepted delimiters include tab, space, or comma. Only a single (1) delimiter is permitted per data file. The default suggestion is to use comma, especially if your data matrix contains strings.

 

fields

required

A list of the field names 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

required

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.

 

Conditionally Required Headers

The following headers are conditionally required to be included in certain SeaBASS files. Some of the most common conditionally required are: /measurement_depth (this MUST be included if a column for "depth" isn't provided) and /below_detection_limit (and its less common counterpart, /above_detection_limit). Some conditionally required headers are specific to certain types of measurements, such as absorption coefficients (see: /volfilt, /null_correction, /area) or HPLC pigment files (see: /HPLC_lab and /HPLC_lab_technician).

above_detection_limit

required IF file contains above_detection_limit values, optional otherwise
Refers to the numeric NULL value used a placeholder for measurements that were made but were above detection limits. If the file contains those types of values, this header is required and those values should be flagged (e.g., set to -7777 or another defined value). Above detection limit values convey some information and are not the same as "missing" values, as missing implies that data were either not measured or invalid.
 
/above_detection_limit=-7777
! Comments
!
! Measurements above detection limit are assigned the value -7777
! upper limit of detection = XYZ concentration
 
If your file contains below detection limit values, then include the header "/above_detection_limit=-7777" followed by comments that describe what the detection limit was for each relevant measurement-type. See also /missing and /below_detection_limit.
 
 

area

optional

(m^2) Use this header to describe the area a sample occupies (e.g., for filter pad absorption measurements.)

 

associated_archives

conditionally required

This header is used in special case submissions where groups of non-SeaBASS format files need to be directly linked to a SeaBASS file (i.e., a bundle of bundles of associated_files). An example of how this has been used includes creating one master TAR bundle consisting of many individual bundles of FASTA DNA data that are each associated with specific rows of data in a SeaBASS file (i.e., the individual bundles are identified on each data row via the field "associated_files").
 
Include this header using the syntax: /associated_archives=my_related_data_bundle.tgz if a SeaBASS file has an accompanying TAR archive bundle of image, auxiliary, or ancillary files. If linking to a list of multiple TAR bundles, separate entries with a comma. Include the file suffix in the entry. This header MUST be used in conjuction with the /associated_archive_types header. Supported formats are listed below (contact the SeaBASS staff if you wish to submit a different format than these):
NOTES: Please contact the SeaBASS staff before you submit a SeaBASS file using this header, as these submissions can be complex and there are restrictions on allowed file types.
 
Note that this header is not for general documentation (use /documents instead), and not for individual calibration files (use /calibration_files instead).

associated_archive_types

conditionally required

Include this header using the syntax: /associated_archive_types=DNA-FASTA if a SeaBASS file has an accompanying TAR archive bundle that is being reported with the /associated_archives header. For multiple entries, separate with a comma.
 
Valid entries for this header are: DNA-FASTQ, DNA-FASTA (for files relating to DNA analysis), benthic, or planktonic (for files relating to accompanying scientific imagery).
 
Please contact the SeaBASS staff if your tar bundle archive does not fit into one of these types.
 
NOTE: this header MUST be used in conjuction with the /associated_archives header.

associated_files

conditionally required

This header is used in unique submissions where a non-SeaBASS format file (or other special raw data) must be directly linked to a SeaBASS file (e.g. - a bethic cover analysis could be accompanied by benthic cover photomosaic images using this header). This header is not for general documentation (use /documents instead), and not for most individual calibration files (use /calibration_files instead). This header is also NOT for generic images of instrumentation, etc; rather, this header is to be used to identify scientific imagery that is part of an observation set or used to support scientific analyses that are being reported in a SeaBASS file.
 
Include this header using the syntax: /associated_files=my_related_data_file.jpg if a SeaBASS file has an accompanying image, auxiliary, or ancillary file. For multiple files, separate entries with a comma.
 
Please explicitly include the file suffix in the entry. If submitting imagery, supported formats are: JPG, PNG, and TIF. Please contact the SeaBASS staff if you plan to submit another format than these.
 
NOTE: Please contact the SeaBASS staff if you plan to submit a SeaBASS file using this header, as there are restrictions on allowed file types. This header MUST be used in conjuction with the /associated_file_types header.

associated_file_types

conditionally required

Include this header if a SeaBASS file has an accompanying auxiliary or ancillary file that is being reported with the /associated_files header. For multiple entries, separate with a comma.
 
Valid entries for this header are:
Please contact the SeaBASS staff if your associated_files do not fit into one of these types.
 
NOTE: this header MUST be used in conjuction with the /associated_files header.

below_detection_limit

required IF file contains below_detection_limit values, optional otherwise
 
Refers to the numeric NULL value used a placeholder for measurements that were made but were below detection limits. If the file contains those types of values, this header is required and those values should flagged (e.g., set to -8888 or another negative number that is distinct from the range of valid measurements). Below detection limit values convey some information and are not the same as "missing" values, as missing implies that data were either not measured or invalid for other reasons.
 
/below_detection_limit=-8888
! Comments
!
! Measurements below detection limit are assigned the value -8888
! lower limit of detection = XYZ concentration
 
If your file contains below detection limit values, then include the header "/below_detection_limit=-8888" followed by comments that describe what the detection limit was for each relevant measurement-type. You do not need to list the limit of detection for every measurement-type in your file, only those that use the below detection limit value (i.e. -8888.) Also, you may consolidate information where practical, for example if the limit of detection for all HPLC pigments is the same concentration (e.g. 0.001 mg/m^3) then a comment like "! HPLC pigments limit of detection = 0.001 mg/m^3" will suffice rather than listing every pigment individually. See also /above_detection_limit and /missing.
 
 

chemical_formula

 conditionally required

The chemical formula of a reported compound, typically associated with the PTR-TOF/MS instrument measuring VOCC concentrations.

Use the syntax "/chemical_formula=...,(C3H6O)H+,(C5H8)H+,...", where each relevant "/fields=...,C3H6O_H,C5H8_H,..." entry has its true chemical formula expressed.

If it is necessary to list multiple chemical formulas, then list all the values in a row, separated by commas.

 

data_use_warning

conditionally required
This header must be included using specific keywords to alert users if the file contains one or more data points that were measured under atypical conditions, or derived experimentally (see below for more information). If a SeaBASS file contains this header, then users should consult the comments in the metadata header or the documentation to learn more and to decide if it is appropriate to use such data for their specific application.
 
Allowed keywords include: optically_shallow, experimental
 
  • optically_shallow: one or more data points were known or suspected to be in optically shallow conditions where the bottom reflectance would impact water leaving values
  • experimental: data are either non-geospatial (e.g., non-field measurements derived under laboratory conditions) or subjectively non-geospatial (e.g., derived from measured water samples but with adjusted light levels or other experimental parameters)
  • negative_data_values: the file contains one or more negative values for types of data that are nominally positive. This warning is used when calibrations or data corrections yielded negative values. Investigators generally must remove or flag negative values prior to submitting to SeaBASS, but there are cases when it is helpful to preserve (slightly) negative values.
  • negative_depths: data contains one or more negative depth or pressure values, which are only allowed if it is necessary and meaningful to retain measurements above the sea-surface
If multiple keywords are applicable, the correct syntax is to list the multiple keywords separated by commas and no spaces (e.g., /data_use_warning=optically_shallow,experimental)
 
To Submitters: Since most of these headers deal with special cases, discuss details with SeaBASS staff before submitting these types of data

HPLC_lab

conditionally required

Applicable (and required) for HPLC data. This header should contain the name of the lab where the HPLC analysis was run.

Example: /HPLC_lab=NASA_GSFC

 

Use in conjunction with the /HPLC_lab_technician header.

HPLC_lab_technician

conditionally required

Applicable (and required) for HPLC data. This header should contain the name of the lab technician who ran the HPLC analysis.

Example: /HPLC_lab_technician=Crystal_Thomas

 

Use in conjunction with the /HPLC_lab header.

id_fields_definitions

conditionally required

This header is a list of one or more user-defined classification categories that modify field names. This header is required if the _id modifier is used in fields.

 

Use the syntax "/id_fields_definitions=#id:<definition>" by listing numbered id suffix followed by the user definition. Multiple definitions may be provided; list them separated by commas. Here is an example of this metadata header paired with its use in /fields:

 

/id_fields_definitions=1id:nanoeukaryotes,2id:picoeukaryotes

/fields=u_ph_1id,u_ph_2id,...

 

 

mass_to_charge

conditionally required

The numeric expression of the mass to charge ratio for a chemical compound, typically associated with the PTR-TOF/MS instrument measuring VOCC concentrations.

Use the syntax "/mass_to_charge=...,mz33.0335,mz34.0335,...", where each relevant "/fields=...,C3H6O_H,C5H8_H,..." entry has its mass to charge (m/z) ratio expressed.

If it is necessary to list multiple mass to charge raatios, then list all the values in a row, separated by commas.

 

measurement_depth

conditionally required

If all the data in the file were collected at a discrete depth, this is that depth (in meters). Applicable (and required) for bottle samples, and buoys and moored radiometers. This header should be excluded or have the value "NA" if a single measurement depth does not apply to the file.

Default is 0 for measurements made above the sea surface.

 

null_correction

conditionally required

Only required if a null correction was applied while calculating absorption coefficients. Generally, null corrections should be performed using absorbance, also known as optical density measurements (unitless). Please note that absorbance data should be submitted without null correction applied. List a null correction by pairing a field name with its null correction value separated by a colon. To report multiple null corrections, separate them by commas. Units are assumed to be the same as the fields used for null correction. Examples: 

/null_correction=abs_ag:0.005,abs_ap:0.001,abs_ag:0.005

/null_correction=ag:0.005 

 

 

optical_depth_warning (deprecated)

conditionally required

This header (/optical_depth_warning=true) was used if a file contained measurements known or suspected to be in optically shallow conditions where the bottom reflectance would impact water leaving values. Using default SeaBASS search settings, files with this header will be excluded from results.
 
NOTE: This header is no longer supported. It has been replaced by "/data_use_warning=optically_shallow" (additional warnings may also be listed as a comma-separated list).

volfilt

conditionally required

The volume filtered (in units of liters) corresponding to one or more fields in a file. This header is only applicable for files with measurement(s) from a discrete sample (for example, to indicate the volume of water filtered for the ap absorption coefficient.)

Use the syntax "/volfilt=FIELD_NAME:#" by listing the field name and volume separated by a colon. For example, /volfilt=ap:0.1

If it is necessary to list multiple volumes filtered for different fields, separate the pairings with a comma.

 

Optional (but recommended) Headers

 While not mandatory, it is recommended that you include as many of the following headers as possible if the relevant information can be provided.

calibration_date

optional

The most recent relevant calibration date for the primary instrument (as YYYYMMDD, e.g., 20190122). This header is optional but highly recommended, or may be set to "NA" if not applicable.

For example: 0 indicates no clouds and 100 indicates completely overcast.

 

data_status

optional

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 users 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.

 

instrument_manufacturer

optional

The instrument manufacturer of the measurements that are being reported (e.g., Biospherical_Instruments_Inc.) Replace any spaces in the name with underscores. If the file contains measurements from multiple sources, list them comma separated.
