CRED REA Coral Health and Disease Assessment at Baker Island, Phoenix Islands, 2006
공공데이터포털
Belt transects along 2 consecutively-placed, 25m transect lines were surveyed at 50-cm intervals as part of Rapid Ecological Assessments conducted at 8 sites at Baker Island in January, 2006 from the NOAA vessel Hi'ialakai (HI06-01). Raw survey data included percent cover of benthic parameters, including live coral, dead coral, carbonate pavement, sand, coral rubble, fleshy macroalgae, crustose coralline algae, and other sessile invertebrates along the two transect lines. In addition, an area of 1-2m on each side of each transect was surveyed; within this area, each coral colony was inspected and every diseased/afflicted colony identified to the lowest taxonomic and type of affliction recorded.

Coral health and disease assessments were conducted along 2 consecutively placed 25-m transects, as part of Rapid Ecological Assessments conducted at 6 sites at Johnston Atoll in the Pacific Remote Island Areas (PRIAs) from 24 January to 14 February 2008, aboard the NOAA ship Hi'ialakai, during the Reef Assessment and Monitoring Program (RAMP) Cruise HI0801. Within an area of 1-3m on each side of both transect lines, each colony was inspected and every diseased/afflicted coral enumerated and identified to the lowest taxonomic level. Raw data included: 1) area surveyed, 2) colony size, 3) taxon identification, 4) type of disease/lesion 5) percent live/dead tissue, 6) severity, 7) lesion distribution, and 8) photographic record. Tissue samples of selected cases were procured for histopathological analyses. These data provide the basis for computing quantitative estimates of disease incidence and prevalence. Samples and photographs provide aid in further disease characterization and description. Histological tissue samples are traditionally fixed in a formaldehyde solution prior to preparation for processing and analysis.
CRED REA Belt Surveys of Coral Population and Disease Assessments at Baker Island, Phoenix Islands, Pacific Remote Islands Areas (PRIAs) in 2010
공공데이터포털
To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 6-8 February 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 8 surveys in total conducted at REA sites around Baker Island 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.

Coral health and disease assessments were conducted along 2 consecutively placed 25-m transects, as part of Rapid Ecological Assessments conducted at 9 sites at Jarvis Island in the Pacific Remote Island Areas during 21 March - 12 April 2008, aboard the NOAA Hi'ialakai Reef Assessment and Monitoring Program (RAMP) Cruise HI0803. Within an area of 1-3m on each side of both transect lines, each colony was inspected and every diseased/afflicted coral enumerated and identified to the lowest taxonomic level. For each affected coral the following information was recorded: colony size, type of affliction, area affected, percent live/dead, and severity of the affliction (mild = 1-10%, moderate = 11-25%, marked = 26-50%, severe = 51-75%, acute = 76-100%). Coral afflictions were classified into one of six general categories (following Willis et al., 2004) including: bleaching, tissue loss, black band disease, skeletal growth anomaly, predation, and other lesions. This latter category included algal overgrowth, as well as unidentified syndromes causing deterioration of scleractinian corals. Tissue samples of selected cases were procured for histopathological analyses. These data provide the basis for computing quantitative estimates of disease incidence and prevalence. Samples and photographs provide aid in further disease characterization and description. Histological tissue samples are traditionally fixed in a formaldehyde solution prior to preparation for processing and analysis.
