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 are 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 adjust the GPS waypoints from the boat's position to the estimated positions of the divers while conducting the surveys, correlate the associated temperature and depth data, and lace the waypoints together into 5-min segments and tow tracks. The dataset includes the adjusted dive points, and the segments and tow tracks are provided as shapefiles. 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.

Tows

Published / External

Tows is a polyline shapefile and it is generated during data processing of the geospatial and SBE39 data. The data represent the estimated survey track of the divers for each 50-minute towed-diver survey. The data is generated by processing the DivePoints using a track processing algorithm, lacing together each of the 5-second survey points, and grouping them by DiveID.

Data Table

Yes

Data table for Tows shapefile from the towed-diver surveys.

ENDTIME

NVARCHAR2

Active The end date and time of the 50-minute towed-diver survey based on the local time zone for the area being surveyed (m/d/yyyy h:mm:ss AM/PM).

FID

NUMBER

Active Sequential unique whole numbers that are automatically generated.

Shape

GEOMETRY

Active Indicates the type of geometry (Polyline), automatically generated in ArcGIS.

DIVEID

NUMBER

Active Unique ID/9-digit serial number for each 50-minute survey. The serial number is formed by concatenating the 4-digit survey year, 2-digit month, 2-digit day, and dive/tow survey number of the day (1-6). The dive number sequence restarts each day and is restricted to values 1-6. For example, the DIVE ID for the first dive on March 13, 2011 is 201103131.

DIVEYEAR

NUMBER

Active 4-digit year the survey was conducted.

REGION

NVARCHAR2

Active 4-letter region code for the geographic region (archipelago) in which the survey was conducted. AMSM: American Samoa MARI: Guam and Commonwealth of Northern Mariana Islands MNHI: Main Hawaiian Islands NWHI: Northwestern Hawaiian Islands PRIA: Pacific Remote Island Areas

ISLAND

NVARCHAR2

Active 3-letter island code for the island at which the survey was conducted. Full name of each island code is listed in the Island_Lookup_Table.csv.

FTEMP_MEAN

NUMBER

Active The mean temperature (in degrees Celsius) recorded by the SeaBird SBE39 mounted on the fish towboard averaged over the 3000 5-second readings made during the 50-minute towed-diver survey. From 2000 to 2009, in most cases the average temperature from the fish and benthic SBE39s is only provided in CTEMP_MEAN, unless the data from a specific time period was reprocessed with a newer version of the Python script (and therefore the mean temperature is provided for both the fish and benthic as well as the combined). All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.

If the SBE39 failed to record temperature data for the majority of the 50-minute survey, this field is left blank.

FTEMP_STDE

NUMBER

Active The standard deviation of temperature (in degrees Celsius) recorded by the SeaBird SBE39 mounted on the fish towboard averaged over the 3000 5-second readings made during the 50-minute towed-diver survey. From 2000 to 2009, in most cases only the average temperature from the fish and benthic SBE39s is provided in CTEMP_MEAN, and therefore the standard deviation of the temperature was provided only in CTEMP_STDE, unless the data from a specific time period was reprocessed with a newer version of the Python script (and therefore the temperature standard deviation is provided for both the fish and benthic as well as the combined). All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.

If the SBE39 failed to record temperature data for the majority of the 50-minute survey, this field is left blank.

BTEMP_MEAN

NUMBER

Active The mean temperature (in degrees Celsius) recorded by the SeaBird SBE39 mounted on the benthic towboard averaged over the 3000 5-second readings made during the 50-minute towed-diver survey. From 2000 to 2009, in most cases the average temperature from the fish and benthic SBE39s is only provided in CTEMP_MEAN, unless the data from a specific time period was reprocessed with a newer version of the Python script (and therefore the mean temperature is provided for both the fish and benthic as well as the combined). All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.

If the SBE39 failed to record temperature data for the majority of the 50-minute survey, this field is left blank.

BTEMP_STDE

Garmin GPSMAP series have been used to collect waypoints in recent years (GPSMAP 76 - GPSMAP 78SC). The datum is set to WGS 1984 with the geographic coordinate system. Seabird SBE 39 Depth and Temperature Recorder has been used to collect temperature in degrees Celsius and depth data in meters. A post-processing script was written in Python 2.5 in 2007, implemented in 2008 and last updated in 2011. The script is run in ArcGIS Desktop environment (ArcGIS 10.3). PIFSC Oracle database: GISDAT.TOW_DIVEPOINTS , TABLESPACE "GISDATA"

Horizontal accuracy is affected by GPS positional error, but should be accurate to within ~10 m. Vertical accuracy to within 1 m based on in situ SBE39 temperature and depths recorder readings. GPS Specifications (Garmin GPSMAP 78 Series): GPS Accuracy is less than 33 ft (10 m) 95% for typical use. Differential correction is not applied. GPS is subject to accuracy degradation to 100 m 2DRMS under the U.S. DoD imposed Selective Availability (SA) Program when activated. Instrument Specifications for SBE39: Temperature (Degrees Celsius): Measurement Range -5 to +45 °C; Initial Accuracy ± 0.002 (-5 to +35 °C); ± 0.01 (+35 to +45 °C), Typical Stability 0.0002 per month, Resolution 0.0001.

The custom built Python script mathematically calculates the diver's positions based on the track, speed, and course of the boat and depth of the divers. However, accuracy of the geolocation estimation (i.e., the true positions of the divers) is greatly influenced by the ocean/underwater conditions, including the current strength and direction, and therefore the accuracy at times is difficult to estimate. This is particularly true when the surface craft is stalled due to currents, the estimation of geolocation is difficult with a python script which assumes the surface craft moves forward. The quality control procedure flags estimated geolocations that are unfit for the further analyses.

The Python script in ArcGIS environment has been used since 2008 for post processing. Prior to 2008, ArcView 3.x script was used to process the GPS points, depths and temperature. When the transition from the ArcView 3.x script was implemented, the Python script was tested and the results were compared with the older script.

There are a few scenarios that will affect the completeness of the data: 1) If the GPS points are not collected, associated diver's positions and survey tracks are not generated 2) If the estimation of the divers' positions are erroneous and it is not possible to correct, the tow tracks/points are flagged and removed from further analyses 3) If SEABIRD sensor (SBE 39) is not operational during surveys, temperature and depth data are not available.

The quality control effort has not been consistent over the years, especially prior to 2008. Generally, the latitude and longitude coordinates of the survey track are recorded every 5 seconds using a Global Positioning System (GPS) receiver on-board the tow boat. In 2015, the coordinates were recorded every 15 seconds.

A GIS analyst reviews the tow tracks and waypoints to flag any anomalies and, if possible, makes corrections based on the available information from the physical data sheet. The data is then migrated to the Oracle database.

The data is captured in several locations: output files from the instruments, MS Access cruise database, and PIFSC Oracle database. The output files and MS Access cruise database reside on the cruise server and regularly backed up by the cruise data manager while at sea. The PIFSC Oracle database is regularly backed up by PIFSC ITS.

Methodology to process the geospatial data (GPS points) from towed-diver surveys, including the associated SBE39 temperature and depth data, to generate the resulting files/shapefiles (Dive Points, Segments, and Tows). The geospatial data are processed using a layback script written in Python that uses various GIS functions to estimate the position of the diver.

Survey protocol

During towed-diver surveys, a pair of divers was towed approximately 60 m behind a small boat, with 1 diver tasked with benthic data collection and 1 diver tasked with data collection on large fishes (>50 cm in total length). Each diver made observations over a visually estimated 10-m swath (5 m out on each side of their respective tow lines, which act as transect lines). Towed at typical speeds of 0.5-1.3 m s-1 (1-2.5 knots), divers attempted to maintain their position ~1 m above the seafloor. Divers recorded observations every 5 minutes over a survey segment length of ~200 m, summarizing the benthic composition, ecologically and economically important fishes, and macroinvertebrates encountered throughout each survey segment. Each survey takes 50 minutes and includes a total of 10 segments, although the actual time and length of surveys occasionally varied depending on environmental conditions and diving or logistical constraints. Four to six surveys were generally completed during each field day. To georeference all data collected during towed-diver surveys, a GPS receiver located on the small boat was programmed to record every 5 seconds. The towed-diver platforms, or towboards, used by the divers were constructed of StarBoard (King Plastic Corp., North Port, Fla.) marine polymer sheets ~100 cm x 50 cm x 2 cm. Each tow board was outfitted with an SBE 39 temperature and pressure (depth) recorder set to record at 5 second intervals. All timing devices were set to Greenwich Mean Time and synchronized each morning using the calibrated clock on the research vessel.

Following each day of field operations for towed-diver surveys, the GPS waypoints collected from the GPS receiver, and the temperature and depth data from the SBE39s were downloaded in text and ascii formats, respectively. A metadata file was generated in notepad listing the local time zone difference from UTC, and the start and end time (in local time) of each tow. A custom built Python script (Python Software Foundation, Wolfeboro Falls, NH) run in an ArcGIS environment was used for processing these waypoints and the corresponding depth and temperature data. This data processing generated 4 standard shapefiles: GPS points, DIVE points, SEGMENTS and TOWS. GPS points represent the raw, uncorrelated, GPS waypoints and were used to generate the other three shapefiles. The Python script: 1) clipped the GPS track points to the survey extent (based on start and stop waypoints for the towed-diver survey), 2) re-positioned 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 temperature and depth 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 (e.g., the DIVE ID for the first towed-diver survey on May 16, 2007 is 200705161, and the SEGMENT ID for segment #5 of during the first survey of the day is 20070516105). A 50-minute towed-diver survey typically includes ten 5-minute segments/observations.

The DIVE points file results from these initial post-processing steps, and includes 1) the adjusted LATITUDE and LONGITUDE, 2) the temperature and depth data recorded from the benthic and fish SBE39s, 3) the mean temperature and mean depth of the combined benthic and fish SBE39 data, and 4) the two serial numbers (DIVE ID and SEGMENT ID). 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. These serial numbers are the link between the geospatial data described here (SEGMENTS and TOWS) and the fish or benthic observation data (i.e., the observation data is mapped to specific geographic locations, or georeferenced). The mean benthic and fish temperature and depths provided in the SEGMENTS and the TOWS shapefiles are both calculated from the benthic and fish temperature and depths in the DIVE points file, and the standard deviations for the means are also provided.

Benthic towboard

SCUBA divers conduct towed-diver surveys to assess relatively large areas of reef habitat and to survey large-bodied reef fishes. This method involves towing two divers (one fish, one benthic) behind a small surface craft that is moving at a velocity of 1-2 mph. The benthic towboard is equipped with a digital camera that is pointing in the downward-looking direction, to record the benthos over which the diver and camera are moving. The benthic diver maneuvers the towboard on which the camera is mounted and records selected data pertaining to the habitat using datasheets mounted on the towboard. The towboard is also equipped with a SEABIRD sensor that records depth and water temperature every 5 seconds. A GPS unit on the surface tow vessel records the trackline over which the divers are being towed.
