Data Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
DSUITEID NUMERIC Unique identifier for each Diel Suite deployed
100
EXPOCODE TEXT Defined as the Ship ICES code + departure date formatted as YYYYMMDD
100
CRUISE_COMMON_NAME TEXT More descriptive name of cruise/mission and is usually in the format [MissionID]-[REGIONDesignation]-[IslandCode if only one visited]
100
MISSION_CODE TEXT A single designation that applies to all the rounds associated with a given mission/cruise
100
ASSOC_REA_SITE TEXT An identifier for the ecological site at the island or atoll (LOCATION) associated with the diel survey. Combines a 3-letter island code (derived from LOCATIONCODE) with a 2-4 digit site number.
100
OCC_SITEID TEXT A 3-dimensional identifier for the fixed location (LATITUDE and LONGITUDE) and depth where the subsurface temperature logger (STR) was deployed at the island or atoll (LOCATION). Includes "OCC" prefix, a 3-letter location code (derived from LOCATION), and a 3-digit site number. A newly deployed instrument is assigned to a pre-existing OCC_SITEID if its coordinates are within a 100-m diameter and its depth is within a 3-m depth cylinder of a pre-existing OCC_SITEID, otherwise, the instrument is assigned a new OCC_SITEID.
100
REGION TEXT The name of the region where the diel survey was conducted in the Pacific Islands region: American Samoa, Pacific Remote Island Areas, Mariana Archipelago, main Hawaiian Islands, Northwestern Hawaiian Islands.
100
REGIONCODE TEXT Code for the region surveyed in the Pacific Islands region: American Samoa (SAMOA), Pacific Remote Island Areas (PRIA), Mariana Archipelago (MARIAN), main Hawaiian Islands (MHI), Northwestern Hawaiian Islands (NWHI).

100
LOCATIONCODE TEXT 3-Letter unique code for LOCATION.
100
LATITUDE NUMERIC Latitude in decimal degrees, WGS84, for the given Site
100
LONGITUDE NUMERIC Longitude in decimal degrees, WGS84, for the given Site
100
DEPTH_M NUMERIC Calculated depth value (m) from pressure, as logged during the CTD deployment. NULL if pressure is NULL.
100
YEAR NUMERIC Year of the mission
100
UTCDATETIME DATE UTC date and time of CTD cast (m/d/yyyy h:mm:ss), collected every 10 seconds to 5 minutes, depending on the site and year.
100
CTD_SAMPLEINTERVAL_SEC NUMERIC Sample interval for CTD data.
100
PRESSURE_DB NUMERIC Measured pressure value in decibars.
100
TEMP_DEGC NUMERIC Measured temperature value in degrees Celsius.
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. NULL if pressure is NULL.
100
COND_S_PER_M NUMERIC Measured conductivity value in Siemens per meter. Occasionally conductivity data cannot be recovered from the CTD, resulting in NULL values.
