Title:
CRED REA Belt Surveys of Coral Population and Disease Assessments at Palmyra Atoll, Pacific Remote Island Areas in 2010
Abstract:
To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 7-13 April 2010, belt transect surveys of coral population and diseases quantitative assessments were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) Cruise HI1001 in the Pacific Remote Island Areas at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, there were 17 surveys in total conducted at REA sites around Palmyra Atoll in the Pacific Remote Island Areas. At the specific REA sites, coral biologists along with algal biologists and marine invertebrate zoologist entered the water and conducted a fine-scale (~300 m2) and high degree of taxonomic resolution REA survey to assess and monitor species composition, abundance, percent cover, size distribution, diversity, and general health of corals, macro-invertebrates, and algae in shallow-water (< 35 m) habitats. As a part of REA surveys, the coral belt surveys were focused on quantifying the diversity, abundance, density, and size-class distribution of the anthozoan and hydrozoan corals as well as the condition and health state of the coral reef populations. The surveys were conducted along two consecutively-placed, 25m transect lines. The belt width was 1-m wide, 0.5-m on each side of the transect line. Within each 25m transect, five 2.5-meter segments were surveyed (beginning at points: 0, 5, 10, 15, and 20 meters), whereby in each segment, all coral colonies whose center fell within 0.5m of either side of the transect line were identified to the lowest taxonomic level possible (genus or species) and two planar size metrics were collected: maximum diameter and diameter perpendicular to the maximum diameter. In addition, the extent of mortality, both recent and old, was estimated for each colony. Observers paid special attention to identifying as best as possible the extent of the former live colony. When a coral colony exhibited signs of disease or compromised health, additional information was recorded including type of affliction (bleaching, skeletal growth anomaly, white syndrome, tissue loss other than white syndrome, trematodiasis, necrosis, other, pigmentation responses, algal overgrowth, and predation), severity of the affliction (mild, moderate, marked, severe, acute), as well as photographic documentation and sometimes tissue samples. Tissue samples were catalogued and fixed in buffered zinc-formalin solution for further histopathological analyses. Raw survey data included species presence and relative abundance, colony counts per taxon, size (width and length), mortality, predation, and health status. A surveyed area was ranging from 10m2 to 25m2 per site.

    REA surveys are investigations that provide a high degree of taxonomic resolution for coral, algae, and other macroinvertebrate communities. The majority of REA surveys were conducted along the forereef slopes of individual islands at depths between 10 and 20 m. However, additional habitats including lagoonal-type patch reef and offshore oceanic banks were surveyed when they existed. During REA surveys, biological assessment teams follow highly structured protocols that are repeated at each REA site. Upon arrival at an REA site, divers entered the water and deployed two 25 m transect lines which are shared with coral surveys that gather community structure, diversity, recruitment, and health status data. The sampling effort takes between 60 and 80 min to complete. The selection of REA sites was made in close consultation with local agencies. Factors considered during REA site selection included: (1) ensuring a range of sample sites representative of the benthic and reef fish habitats around each island; (2) selecting a mixture of sites within and outside of marine protected areas; (3) selecting a mixture of both 'impacted' and 'least impacted' sites; (4) selecting some sites adjacent to local villages; and (5) selecting a number of sites that could be compared to and complement previous assessment and monitoring work as well as future coral reef monitoring proposed by local agencies. It is important to note that access to REA sites can be limited by wave exposure, weather conditions, and other environmental factors such as currents, which can affect the ability to re-survey sites between years. Transect placement was guided by: (1) a focus on hard-bottom communities; (2) deploying lines along an isobath to the extent possible at each site, and (3) laying the transect lines into the prevailing current.
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Observations were made by two divers who are experts in coral biology. The population parameter survey is conducted one time per site per survey year; it is not replicated.
  2. How accurate are the geographic locations?
    GPS unit
  3. How accurate are the heights or depths?
    Dive computer and SCUBA depth gauge
  4. Where are the gaps in the data? What is missing?
    The survey sites were selected to be representative of the dominant habitats at this reef system. Efforts were made to include broad spatial coverage of the reef area, but weather conditions or other environmental constraints may have precluded the team from surveying windward or exposed sites.
  5. How consistent are the relationships among the observations, including topology?
    With the exception of the non-quantitative survey along the backreef, the same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists.
