Pacific Reef Assessment and Monitoring Program: Geospatial, temperature, and depth data collected during towed-diver surveys of coral reef ecosystems across the U.S. Pacific Islands from 2000-09-09 to 2017-06-20 (NCEI Accession 0189889)

browse graphicPreview graphic
The geospatial, temperature and depth data included in this dataset are from towed-diver surveys (also referred to as towboard surveys) of coral reef ecosystems conducted during Pacific Reef Assessment and Monitoring Program (RAMP) cruises to the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas from 2000 to 2017 by the Ecosystem Sciences Division (formerly known as the Coral Reef Ecosystem Division) at the NOAA Pacific Islands Fisheries Science Center (PIFSC).

Generally, the towed-diver survey method involved towing a pair of SCUBA divers—one benthic and one fish—behind a small boat for 50 minutes, approximately following the ~15-m depth contour and covering a linear distance of about 2-3 kilometers per survey. A complete 50-minute towed-diver survey is divided into ten 5-minute segments, and up to 6 towed-diver surveys were conducted per day.

Each diver was equipped with a towboard outfitted with instrumentation and used to record observations, and the divers attempted to maintain position ~1 meter above the surface of the reef for the duration of the survey. Both towboards were equipped with a SeaBird™ SBE39 temperature/depth sensor that recorded water temperature and depth every 5 seconds. The survey tracks were also recorded every 5 seconds using a GPS receiver located on the small boat. The survey tracks were georeferenced and a script was applied to 1) adjust the GPS waypoints from the boat's position to the estimated positions of the divers while conducting the surveys, 2) correlate the associated temperature and depth data, and 3) lace the waypoints together (with the merged temperature and depth data) into 5-min segments and tow tracks. The dataset includes the adjusted dive points, as well as the segments and tow tracks which are provided as shapefiles.

Purpose The geospatial data are collected to georeference the visual observations from towed-diver surveys of large-bodied fishes and benthic habitats/key benthic species and to provide ancillary temperature and depth data so that biotic observations could be linked to salient physical parameters. Towed-diver surveys are a good method for obtaining a general description of large reef areas, assessing large-scale disturbances (e.g., bleaching), and assessing general distribution and abundance patterns of large-bodied (>50 cm) fishes and macro-invertebrates (e.g., crown of thorns, giant clams). Towed-diver surveys were conducted during Pacific Reef Assessment and Monitoring Program (Pacific RAMP) to support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems. Pacific RAMP, established by the Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) and supported by NOAA's Coral Reef Conservation Program (CRCP), was tasked with documenting and understanding the status and trends of coral reef ecosystems in the U.S. Pacific Islands Region. Pacific RAMP involved interdisciplinary monitoring of oceanographic conditions and biological surveys of organisms associated with hard-bottom habitats in the 0-30 m depth range and aimed to support integrated, consistent and comparable monitoring of coral reef systems. RAMP missions were conducted in each Pacific region, including the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas, every 1-3 years. Starting in 2013, Pacific RAMP was incorporated into NOAA's National Coral Reef Monitoring Program.

Processing Steps
  • Parameter or Variable: DEPTH - SENSOR (measured); Units: meter; Observation Category: in situ; Sampling Instrument: Temperature Sensors; Sampling and Analyzing Method: A SeaBird™ SBE39 temperature/depth logger was mounted to each of the towboards (benthic and fish) and recorded water temperature and depth every 5 seconds. The loggers were set to Greenwich Mean Time and synchronized with the other timing devices each morning using the calibrated clock on the research vessel. Following each day of field operations (up to 6 towed-diver surveys per day), the SBE39 temperature and depth data from each towboard was downloaded in ascii format and post-processed with the corresponding GPS waypoints and metadata (start/end time for each towed-diver survey) using a custom Python script run in ArcGIS. The DIVE POINTS file includes the temperature and depth data recorded (MEASURED) from the benthic and fish SBE39s and also includes the mean temperature and mean depth of the combined benthic and fish SBE39 data (CALCULATED)..
  • Parameter or Variable: WATER TEMPERATURE (measured); Units: degrees Celsius; Observation Category: in situ; Sampling Instrument: Temperature Sensors; Sampling and Analyzing Method: A SeaBird™ SBE39 temperature/depth logger was mounted to each of the towboards (benthic and fish) and recorded water temperature and depth every 5 seconds. The loggers were set to Greenwich Mean Time and synchronized with the other timing devices each morning using the calibrated clock on the research vessel.

  • Parameter or Variable: LATITUDE (calculated); Units: decimal degree; Observation Category: in situ; Sampling Instrument: GPS; Sampling and Analyzing Method: A GPS receiver located on the small boat recorded the boat’s position at the same interval as the SeaBird™ SBE39 temperature/depth logger (every 5 seconds). The GPS was set to Greenwich Mean Time and synchronized with the other timing devices each morning using the calibrated clock on the research vessel. Following each day of field operations (up to 6 towed-diver surveys per day), the GPS data was downloaded in txt format and post-processed with the corresponding SBE39 data and metadata (start/end time for each towed-diver survey) using a custom Python script run in ArcGIS. The script: 1) clipped the GPS track points to the survey extent (based on start and stop waypoints), 2) repositioned the GPS track points to the divers’ location (based on the track, speed, and course of the boat and the divers’ depths), 3) imported the corresponding SBE39 data using the metadata time stamps, and 4) added two unique serial numbers. The serial numbers include DIVE ID that represents the date of the 50-minute tow survey (YYYYMMDD) plus the single-digit tow number for the day (1-6), and SEGMENT ID that represents DIVE ID plus the 2-digit segment (01-10) within the tow (a 50-minute towed-diver survey typically includes ten 5-minute segments/observations). The DIVE POINTS file results from these initial processing steps, and includes the adjusted LATITUDE and LONGITUDE (CALCULATED), the SBE39 data (recorded and combined mean), and the serial numbers. The DIVE POINTS are then laced together and 1) grouped by SEGMENT ID to generate the SEGMENTS polyline shapefile, and 2) grouped by DIVE ID to generate the TOWS polyline shapefile..

The serial numbers include DIVE ID that represents the date of the 50-minute tow survey (YYYYMMDD) plus the single-digit tow number for the day (1-6), and SEGMENT ID that represents DIVE ID plus the 2-digit segment (01-10) within the tow (a 50-minute towed-diver survey typically includes ten 5-minute segments/observations). The DIVE POINTS file results from these initial processing steps, and includes the adjusted LATITUDE and LONGITUDE (CALCULATED), the SBE39 data (recorded and combined mean), and the serial numbers. The DIVE POINTS are then laced together and 1) grouped by SEGMENT ID to generate the SEGMENTS polyline shapefile, and 2) grouped by DIVE ID to generate the TOWS polyline shapefile..
  • Parameter or Variable: DEPTH - SENSOR (calculated); Units: meter; Observation Category: in situ; Sampling Instrument: Temperature Sensors; Sampling and Analyzing Method: The mean benthic and fish depths provided in the SEGMENTS and the TOWS shapefiles are both calculated from the benthic and fish depths in the DIVE POINTS file.; Data Quality Method: The standard deviations for the mean benthic and fish depths are provided in the SEGMENTS and the TOWS shapefiles..
  • Parameter or Variable: WATER TEMPERATURE (calculated); Units: degrees Celsius; Observation Category: in situ; Sampling Instrument: Temperature Sensors; Sampling and Analyzing Method: The mean benthic and fish temperatures provided in the SEGMENTS and the TOWS shapefiles are both calculated from the benthic and fish temperatures in the DIVE POINTS file.; Data Quality Method: The standard deviations for the mean benthic and fish temperatures are provided in the SEGMENTS and the TOWS shapefiles..
