55945 Entity Published / External 54926 National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites in the Pacific Remote Islands Marine National Monument since 2015 Data Set Completed ADCP entities and attributes for diel surveys where data exists. If the CTD sensor failed to log pressure as in a diel suite deployment in 2016, depth was calculated with pressures as recorded from ADCP. Data Table Yes ADCP entity for diel surveys 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_COMMON_NAME TEXT No No Active More descriptive name of cruise/mission and is usually in the format [MissionID]-[REGIONDesignation]-[IslandCode if only one visited] 4 MISSION_CODE TEXT No No Active A single designation that applies to all the rounds associated with a given mission/cruise 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 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. 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 DEPTH_M NUMERIC No No Active OCC Survey depth (m) from dive computer at diel suite deployment 14 YEAR NUMERIC No No Active Year of the mission 15 UTCDATETIME DATE No No Active UTC date and time of pressure measured from the ADCP, collected every 2 minutes. 16 CTD_SAMPLEINTERVAL_SEC NUMERIC No No Active Sample interval for CTD data. 17 PRESSURE_DB NUMERIC No No Active Measured pressure value in decibars, measured from an ADCP co-located at the SiteID with a CTD that collected only temperature and conductivity (a non-standard CTD for most diel surveys). ADCP pressure is substituted for pressure measured from the CTD in the carbonate chemistry calculations for diel surveys conducted in 2016 in the PRIA. 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 ADCP_SAMPLEINTERVAL_SEC NUMERIC No No Active Sample interval for ADCP data. 22 HEIGHTBIN_M NUMERIC No No Active Height bin above the ADCP. Each height bin is represented as the upper limit of the bin height above the sensor on the seafloor (for example, a 1.4 m bin represents current data collected between 0.4 m and 1.4 m above the ADCP). ADCP data include a blanking region, or a small distance in front of the transducer in which measurements cannot be made, of 0.2-0.4 m, and typically grouped into 1-m height bins, though smaller bin sizes (0.25 m or 0.5 m) are used for shallower deployments (2016). 23 DIRECTION_DEG NUMERIC No No Active Current direction, measured in degrees (0-360). Data are trimmed to a maximum height bin for each time interval using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides. 24 SPEED_MS NUMERIC No No Active Current magnitude (speed), measured in meters per second. Calculated as the square root of the sum of the squared u and v velocities. Data are trimmed to a maximum height bin for each time interval using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides. gov.noaa.nmfs.inport:55945 Annette DesRochers 2019-03-22T19:33:20 SysAdmin InPortAdmin 2022-08-09T17:11:00 2021-08-03 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 2021-08-03 1 Year 2022-08-03
