Entity Information

Entity Type:	Spreadsheet
Active Version?:	Yes
Description:	Column descriptions for CTD datasets.
Change Summary:	As of 2022, SHALLOWCTDID was deprecated and CTDCASTNAME was generated. LOCATION and LOCATIONCODE (used in 2013, 2016, 2024) are equivalent to ISLAND and ISLANDCODE (used in 2019).

Data Attributes

Attribute Summary

	Name	Type	Description
100	CTDCASTNAME	Text	Unique ID for CTDCASTID: typically cruise/MISSION ID, last 4 digits of CTD serial number, date and cast number/id.
100	CTDDATAID	Numeric	Unique numeric ID for each depth bin within a CTD cast (6-digit number).
100	CTDCASTID	Numeric	Unique numeric ID of CTD cast (4 or 5-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	Numeric	Latitude in decimal degrees, WGS84, for the CTD cast.
100	LONGITUDE	Numeric	Longitude in decimal degrees, WGS84, for the CTD cast.
100	UTCDATETIME	Date	UTC date and time of CTD cast (yyyy-mm-dd hh:mm:ss).
100	CASTYEAR	Numeric	4-digit year the CTD cast was conducted (UTCDATETIME).
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	Numeric	Measured pressure value in decibars.
100	DEPTH_M	Numeric	Calculated depth value in meters.
100	TEMP_DEGC	Numeric	Measured temperature value in degrees Celsius.
100	COND_S_PER_M	Numeric	Measured conductivity value in Siemens per meter.
100	SALN_PSU	Numeric	Calculated salinity value in Practical Salinity Units (PSU).
100	DENSITY_SIGMAT	Numeric	Calculated sigma-t density value, the density of seawater at atmospheric pressure minus 1000 kilograms / cubic meter.
