1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:
Guam Long-term Coral Reef Monitoring Program Coral Colony Size and Condition Surveys since 2010
1.2. Summary description of the data:

The Government of Guam's Comprehensive Long-term Monitoring at Permanent Sites in Guam project, also known as the Guam Long-term Coral Reef Monitoring Program (GLTMP), is a NOAA-funded project currently coordinated through the University of Guam Marine Laboratory. The program involves the regular, intensive collection of data for a suite of coral reef ecosystem health parameters at high priority reef areas (HPRAs) around Guam, as well as critical support for coral bleaching response and other activities carried out by the multi-partner Guam Coral Reef Response Team. The program currently utilizes a split-panel sampling approach, whereby a mix of permanent and non-permanent sampling stations (one sampling station = one transect) are visited within each HPRA. The HPRAs were selected by an advisory body comprised of reef managers, researchers, and technicians; these reef areas were not intended to be representative of Guam's reefs more broadly. The locations of the sampling stations within each HPRA are generated randomly using GIS software. Various coral reef surveys are carried out on an annual basis along the seaward slope between 7 and 15 m depth in the Tumon Bay Marine Preserve and in East Agana Bay, while surveys are carried out biennially within the Piti Bomb Holes Marine Preserve, the Achang Reef Flat Marine Preserve, the eastern side of the Cocos Barrier Reef (Cocos-East), and Fouha Bay. Surveys were also carried at along reef margin (1-2 m) and slope (2-15 m) of Western Shoals, in Apra Harbor, in 2011. The surveys, which are currently conducted by University of Guam Marine Laboratory biologists, and which were supported by NOAA PIRO through 2019, currently include benthic photo transects, stationary point count fish surveys, macroinvertebrate belt transects, and chain-length rugosity surveys. The GLTMP has conducted surveys at the Tumon and East Agana HPRAs since 2010 and the Piti HPRA since 2012. Data collection for the Achang and Cocos-East HPRAs began in 2014 and at the Fouha Bay HPRA in 2015. Baseline data is available for the Western Shoals HPRA from 2011 but this site has not been re-visited since its establishment due to shifting management priorities.

Corals are the main contributor to coral reef accretion, provide critical habitat for numerous reef organisms, and serve as a food source for some reef organisms. In recognition of the critical important of corals, coral colony size and condition surveys were carried out by the GLTMP at several HPRAs on a regular basis between 2010 and 2019. Nearly all of the coral quadrat surveys were carried out by a single observer. The size and condition are assessed for all coral colonies found within quadrats placed every 5 meters along 30-m transects (15-m transects for the Western Shoals HPRA, 25 m for other HPRAs prior to 2018). These monitoring data on coral communities provide results on coral colony density, size, condition, and diversity; allow for exploration of community structure by functional group and size; and can be used to detect changes in coral communities over time. The coral quadrat surveys were eliminated beginning in 2020 due to staff capacity limitations, but the nails marking the quadrat locations at some sampling stations have been been maintained opportunistically.

IMPORTANT NOTE: The plate-and-pillar coral, Porites rus, was excluded from the coral quadrat survey during the 2019 and 2020 field seasons due to the considerable time required to properly assess the size and condition of this abundant species and the limited availability of the program coordinator to carry out the specialized survey.

(describe or provide URL of description):

Lineage Statement:
The Coral Colony Size and Condition (or Coral Quadrat) Survey methodology, employed by the Guam Long-term Coral Reef Monitoring Program since 2010

Process Steps:

  • Coral colony size and condition surveys are carried out at all sampling stations when program capacity is sufficient to do so. All sampling stations have been selected in hard-bottom habitats using a stratified random sampling design, and the stations have been designed using the split-panel approach (combination of fixed and non-fixed transects).
  • Each sampling station is located using a GPS receiver. Upon reaching a given station, a small weight and line tied to a buoy is carefully lowered to the ocean floor. In optimal situations where four divers are available, two divers enter the water first to carry out the fish surveys. Starting at the weight tied to the buoy, a 30 m transect is laid out [25 m-long transects were used prior to 2017]. The transect is laid out in a clockwise direction relative to the island, following the depth contour if it is readily determined; if the area is relatively flat and a depth contour is not readily discernible the transect is laid at an angle parallel to the reef margin (which is determined prior to entering the water). Compact digital point and shoot cameras and housings are used by individual observers to document unknown organisms, incidences of coral disease, and species/behaviors of special interest. For the initial establishment of fixed sampling stations, 24 inch rebar is installed at the beginning of the transect and 12 inch rebar is installed at the center and end of the transect; four-inch concrete nails are installed in at least two of the corners of each quadrat used for coral size and condition surveys. For the Western Shoals site, rebar and concrete nails were not used and instead a small PVC float was tied to dead coral with a line at the beginning of the transect and large zip ties were placed at the beginning, middle, and end of the transect. Two small zip ties were used to mark two corners of each permanent quadrat location. To minimize diver disruptions, the two divers conducting the benthic surveys enter the water after the fish team has finished enumerating fish. In situations where only three divers are available, all three divers enter the water at the same time and remain as a three-person buddy team to ensure diver safety throughout the survey. A fish diver partners with a benthic diver when two fish divers are not available. In this situation, the fish diver lays the transect and conducts the first SPC at 22.5 m while the benthic diver works from 0-15 m; they then switch positions along the transect so that the fish diver can carry out the second SPC.
  • Shortly after a benthic team diver begins the photo transect on the left side of the transect, another diver then identifies and measures all coral colonies within a 0.5 x 0.5 m quadrat (1 x 0.75 m quadrat for the Western Shoals and Fouha Bay sites) placed at 0 m, 5 m, 10 m, 15 m, 20 m and 25 m along the right side of the transect. In rare instances time limitations prevented data collected for all six quadrat positions, and when 25 m-long transects were used (prior to 2017) quadrats were usually not placed at the 25 m mark. For each quadrat location, the bottom-left corner of the quadrat is coincident with the appropriate meter mark (0 m, 5 m, etc.) along the transect. Only those colonies whose geometric center is within the quadrat are counted. Percent old dead, percent recent dead, and disease type and severity are recorded for each colony. The cause of tissue mortality is also noted if it can be determined with a reasonable degree of confidence. Measurements of the longest dimension and the width of the colony perpendicular to the longest dimension are made. An effort is made to carefully count all visible colonies, including recruits/juvenile corals. Care is taken to prevent the count of remnants of larger colonies as coral recruits/juvenile corals. Any tissue isolate suspected of being a remnant of a larger colony is noted as such, in order to prevent the calculation of erroneous coral colony density. At least two planar view photos are taken of each quadrat in order to maintain a photographic record of all quadrats. Photos are also taken of corals for which species identification is uncertain, of unidentified sources of mortality, or of species or conditions of particular interest.
  • Raw data include individual colony records with the corresponding methodological information and physical data that reflect the description of the site. An individual colony record for all corals includes colony species/genus identification; maximum diameter (cm); perpendicular diameter (cm); percent old dead; percent recent dead; and condition type and severity; photo (y/n); collected (y/n); fragment (y/n), tissue remnant (y/n); and additional comments. The physical and methodological data for all records includes the following: site, station, station type, date (day, month, year), latitude (dd), longitude (dd), transect number, transect length, quadrat, quadrat size, depth (m), habitat.

5.2. Quality control procedures employed
(describe or provide URL of description):

All observations entered into the database through the online data entry system are compared against observations recorded on the raw data sheet. Once all database records are verified the quality control process is marked as complete for all observations associated with a given station/sampling period. This process is currently carried out by the Program Coordinator or the full-time field technician. It should also be noted that the data management system employs hard and soft validation to minimize data entry errors.
