Data Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
SHALLOWCTDID Text Unique ID for CTD Cast: typically cruise/MISSION ID, REGION (optional), 3-letter island code (LOCATIONCODE), last 4 digits of CTD serial number, cast number/id.
100
CTDDATAKEY Long Integer Unique numeric ID for each depth bin within a CTD cast (6-digit number).
100
CTDCASTID Long Integer Unique numeric ID of CTD cast (4-digit number).
100
ASSOC_OCC_SITEID Text An identifier for the fixed climate site associated with the CTD cast, if any. An OCC_SITEID is a 3-dimensional identifier that describes a location (LATITUDE and LONGITUDE) and depth of a fixed NCRMP climate site and includes "OCC" prefix, a 3-letter location code (derived from LOCATIONCODE), and a 3-digit site number. CTD casts are assigned an associated OCC_SITEID (ASSOC_OCC_SITEID) rather than an OCC_SITEID because the CTD profile includes the entire water column rather than a single depth on the benthos. A CTD cast is assigned an ASSOC_OCC_SITEID only if its coordinates are within a 150-m radius of a pre-existing OCC_SITEID; otherwise, no ASSOC_OCC_SITEID is assigned.
100
ASSOC_REA_SITE Text An identifier for the ecological site at the island or atoll (LOCATION) associated with the CTD cast. Combines a 3-letter island code (derived from LOCATIONCODE) with a 2-4 digit site number.
100
CRUISE Text Mission identifier.
100
REGIONCODE Text Code for REGION.
100
REGION Text The name of the region where the CTD cast was conducted in the Pacific Islands region: American Samoa, Pacific Remote Island Areas, Mariana Archipelago, main Hawaiian Islands, Northwestern Hawaiian Islands.
100
LOCATIONCODE Text 3-Letter unique code for LOCATION.
100
LOCATION Text Name of island or atoll where the CTD cast was conducted in the Pacific Islands region (REGION).
100
LATITUDE Double Latitude in decimal degrees, WGS84, for the CTD cast.
100
LONGITUDE Double Longitude in decimal degrees, WGS84, for the CTD cast.
100
UTCDATETIME Date/Time UTC date and time of CTD cast (yyyy-mm-dd hh:mm:ss).
100
CASTYEAR Double 4-digit year the CTD cast was conducted (UTCDATETIME).
100
WATERSAMPLE Text A discrete water sample was/was not (TRUE/FALSE) collected in conjunction with the CTD cast.
100
OFFSHORE_YN Text CTD cast was/was not (YES/NO) conducted offshore, where offshore is defined as a cast location (LATITUDE and LONGITUDE) more than 10km away from land (for islands) or the 20m depth contour (for atolls).
100
SURVEY_DESIGN Text NCRMP survey design associated with the CTD cast. Survey designs include: casts conducted at permanent climate sites (Permanent); casts co-located with fish or benthic stratified random survey sites (Stratified_Random); casts at random sites not associated with climate, benthic, or fish sites (Random); and casts conducted offshore to collect end member data (End_member).
100
PRESSURE_DB Double Measured pressure value in decibars.
100
DEPTH_M Double Calculated depth value in meters.
100
TEMP_DEGC Double Measured temperature value in degrees Celsius.
