36762 CTD Entity Entity Published / External 36761 National Coral Reef Monitoring Program: Shallow Water Conductivity-Temperature-Depth (CTD) Profiles for select locations across American Samoa from 2015 to 2023 Data Set Conductivity-Temperature-Depth Entity and Attributes Spreadsheet Yes Conductivity-Temperature-Depth Entity As of 2018, these are the active / relevant fields: SHALLOWCTDID, CTDDATAKEY, CTDCASTID, ASSOC_OCC_SITEID, ASSOC_REA_SITE, CRUISE, REGIONCODE, REGION, LOCATIONCODE, LOCATION, LATITUDE, LONGITUDE, UTCDATETIME, CASTYEAR, WATERSAMPLE, OFFSHORE_YN, SURVEY_DESIGN, PRESSURE_DB, DEPTH_M, TEMP_DEGC, COND_S_PER_M, SALN_PSU, DENSITY_SIGMAT In 2023, CTDDATAKEY was updated to CTDDATAID , SHALLOWCTDID updated to CTDCASTNAME. 1 CTDCASTNAME TEXT No No Active Unique ID for CTDCASTID: typically cruise/MISSION ID, last 4 digits of CTD serial number, date and cast number/id. 2 CTDDATAID NUMERIC No No Active Unique numeric ID for each depth bin within a CTD cast (6-digit number). 3 CTDCASTID NUMERIC No No Active Unique numeric ID of CTD cast (4-digit number). 4 ASSOC_OCC_SITEID TEXT No No Active 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. 5 ASSOC_REA_SITE TEXT No No Active 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. 6 CRUISE TEXT No No Active Mission identifier. 7 REGIONCODE TEXT No No Active Code for REGION. 8 REGION TEXT No No Active 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. 9 LOCATIONCODE TEXT No No Active 3-Letter unique code for LOCATION. 10 LOCATION TEXT No No Active Name of island or atoll where the CTD cast was conducted in the Pacific Islands region (REGION). 11 LATITUDE NUMERIC No No Active Latitude in decimal degrees, WGS84, for the CTD cast. 12 LONGITUDE NUMERIC No No Active Longitude in decimal degrees, WGS84, for the CTD cast. 13 UTCDATETIME DATE No No Active UTC date and time of CTD cast (yyyy-mm-dd hh:mm:ss). 14 CASTYEAR NUMERIC No No Active 4-digit year the CTD cast was conducted (UTCDATETIME). 15 WATERSAMPLE TEXT No No Active A discrete water sample was/was not (TRUE/FALSE) collected in conjunction with the CTD cast. 16 OFFSHORE_YN TEXT No No Active 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). 17 SURVEY_DESIGN TEXT No No Active 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). 18 PRESSURE_DB NUMERIC No No Active Measured pressure value in decibars. 19 DEPTH_M NUMERIC No No Active Calculated depth value in meters. 20 TEMP_DEGC NUMERIC No No Active Measured temperature value in degrees Celsius. 21 COND_S_PER_M NUMERIC No No Active Measured conductivity value in Siemens per meter. 22 SALN_PSU NUMERIC No No Active Calculated salinity value in Practical Salinity Units (PSU). 23 DENSITY_SIGMAT NUMERIC No No Active Calculated sigma-t density value, the density of seawater at atmospheric pressure minus 1000 kilograms / cubic meter. gov.noaa.nmfs.inport:36762 Kevin Trick 2017-02-10T18:56:04 Lori Luers 2025-01-21T19:18:49 2025-01-21 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 2021-03-10 1 Year 2022-03-10
