55937 Entity Published / External 54894 National Coral Reef Monitoring Program: Diel oceanographic and carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites across the Hawaiian Archipelago since 2016 Data Set Completed Conductivity-Temperature-Depth entities and attributes for diel surveys. If CTD sensor failed to log pressure as in during a deployment in 2016, depth was calculated with pressures as recorded from ADCP. Data Table Yes Conductivity-Temperature-Depth entity for diel surveys. In 2021 columns were renamed and added to standardize data structure. Updated in 2024 to rename CRUISE_COMMON_NAME to CRUISE_ID and DEPTH_M to SITE_DEPTH_M. 1 DSUITEID NUMERIC No No Active Unique identifier for each Diel Suite deployed. 2 EXPOCODE TEXT No No Active Defined as the Ship ICES code + departure date formatted as YYYYMMDD. 3 CRUISE_ID TEXT No No Active A single designation that applies to all the rounds associated with a given mission/cruise. 4 MISSION_CODE TEXT No No Active More descriptive name of cruise/mission and is usually in the format [MissionID]-[REGIONDesignation]-[IslandCode if only one visited]. 5 ASSOC_REA_SITE TEXT No No Active 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. 6 OCC_SITEID TEXT No No Active A 3-dimensional identifier for the fixed site location (LATITUDE and LONGITUDE) and depth. Includes "OCC" prefix, a 3-letter location code (derived from LOCATION), and a 3-digit site number. 7 REGION TEXT No No Active 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. 8 REGIONCODE TEXT No No Active 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). 9 LOCATION TEXT No No Active Name of island or atoll where the sample was collected in the Pacific Islands region (REGION). 10 LOCATIONCODE TEXT No No Active 3-Letter unique code for LOCATION. 11 LATITUDE NUMERIC No No Active Latitude in decimal degrees, WGS84, for the given site. 12 LONGITUDE NUMERIC No No Active Longitude in decimal degrees, WGS84, for the given site. 13 SITE_DEPTH_M NUMERIC No No Active Depth of sensor deployment site in meters. Measured by dive computer at time of deployment. 14 YEAR NUMERIC No No Active Year of the mission. 15 UTCDATETIME DATE No No Active UTC date and time of observation (yyyy-mm-dd hh:mm:ss). 16 CTD_SAMPLEINTERVAL_SEC NUMERIC No No Active Sample interval for CTD data in seconds. 17 PRESSURE_DB NUMERIC No No Active Measured pressure value in decibars. 18 TEMP_DEGC NUMERIC No No Active Measured temperature value in degrees Celsius. 19 SALN_PSU NUMERIC No No Active Calculated salinity value in Practical Salinity Units (PSU). 20 DENSITY_SIGMAT NUMERIC No No Active Calculated sigma-t density value, the density of seawater at atmospheric pressure minus 1000 kilograms/cubic meter. NULL if pressure is NULL. 21 COND_S_PER_M NUMERIC No No Active Measured conductivity value in Siemens per meter. Occasionally conductivity data cannot be recovered from the CTD, resulting in NULL values. gov.noaa.nmfs.inport:55937 Annette DesRochers 2019-03-22T19:24:44 Lori Luers 2026-06-17T17:19:22 2026-06-17 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No 2021-08-06 1 Year 2022-08-06
