Conductivity-Temperature-Depth Entity

Entity Information

Entity Type
Spreadsheet

Data Attribute / Type Description
CTDCASTNAME
TEXT 		Unique ID for CTDCASTID: typically cruise/MISSION ID, last 4 digits of CTD serial number, date and cast number/id.
CTDDATAID
NUMERIC 		Unique numeric ID for each depth bin within a CTD cast (6-digit number).
CTDCASTID
NUMERIC 		Unique numeric ID of CTD cast (4-digit number).
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.
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.
CRUISE
TEXT 		Mission identifier.
REGIONCODE
TEXT 		Code for REGION.
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.
LOCATIONCODE
TEXT 		3-Letter unique code for LOCATION.
LOCATION
TEXT 		Name of island or atoll where the CTD cast was conducted in the Pacific Islands region (REGION).
LATITUDE
NUMERIC 		Latitude in decimal degrees, WGS84, for the CTD cast.
LONGITUDE
NUMERIC 		Longitude in decimal degrees, WGS84, for the CTD cast.
UTCDATETIME
DATE 		UTC date and time of CTD cast (yyyy-mm-dd hh:mm:ss).
CASTYEAR
NUMERIC 		4-digit year the CTD cast was conducted (UTCDATETIME).
WATERSAMPLE
TEXT 		A discrete water sample was/was not (TRUE/FALSE) collected in conjunction with the CTD cast.
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).
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).
PRESSURE_DB
NUMERIC 		Measured pressure value in decibars.
DEPTH_M
NUMERIC 		Calculated depth value in meters.
TEMP_DEGC
NUMERIC 		Measured temperature value in degrees Celsius.
COND_S_PER_M
NUMERIC 		Measured conductivity value in Siemens per meter.
SALN_PSU
NUMERIC 		Calculated salinity value in Practical Salinity Units (PSU).
DENSITY_SIGMAT
NUMERIC 		Calculated sigma-t density value, the density of seawater at atmospheric pressure minus 1000 kilograms / cubic meter.
