Title:
CRED and partners: Environmental Monitoring of Coral Bleaching and Disease in the Hawaiian Islands; belt Surveys of Coral Population and Disease Assessments at Hawaii, Hawaii in 2011
Abstract:
The field data described herein are part of a joint NESDIS-NMFS project aimed at advancing the understanding of the occurrence, abundance, and outbreak of coral bleaching and disease in the Hawaiian Archipelago through expanded field surveys and in-situ and remotely-sensed temperature data. To this end Line-Point-Intercept (LPI), belt-transect surveys of coral population, and diseases quantitative assessments were conducted on HAWAII in the MAIN HAWAIIAN ISLANDS by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) and partners. At the specific sites, coral biologists conducted Line-Point-Intercept (LPI) and coral belt surveys, focused at quantifying the composition, relative abundance, density, and size-class distribution of the anthozoan and hydrozoan corals, as well as the condition and health state of the coral populations. The surveys were conducted along two consecutively-placed, 25m transect lines. The LPI surveys documented the composition of the coral reef community at 25 or 50cm intervals, for 50 or 100 points per transect. The belt width was 1-m wide (0.5-m on each side of the transect line), for community structure assessments, and 1 or 2 m wide (0.5 or 1.0 m on each side of the transect line), for coral condition and health surveys. Within each 25m transect, up to 15, 1.0-meter segments were surveyed, 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 colony size visually estimated and binned by its maximum diameter in one of 7 size classes: 0-5cm, 5-10cm, 10-20cm, 20-40cm, 40-80cm, 80-160cm, or >160cm. 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. Raw survey data included species presence and relative abundance, colony counts per taxon, size (width and length), mortality, predation, and health status. The surveyed area ranged from 25m2 to 50m2 per site.

Why was the data set created?

Expanded field surveys to advance the understanding of the occurrence, abundance, and outbreaks of coral bleaching and disease in the Hawaiian Archipelago.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: Unknown (process 1 of 1)
    Surveys are investigations that provide a high degree of taxonomic resolution for coral. The majority of surveys were conducted along the forereef slopes at depths between 3 and 20 m. During surveys, the biological assessment team follows highly structured protocols that are repeated at each site. The selection of survey sites was made in close consultation local partners. Factors considered during site selection included: (1) budgetary feasibility; (2) accessibility; (3) replicability; (4) overlap with other local/Federal monitoring efforts; and (5) NOAA-CRCP programmatic site prioritization.
  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 and disease surveys are conducted one time per site per survey visit, with temporal replication within the survey year.
  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 for this type of work. Efforts were made to include broad spatial coverage of the reef area, but weather conditions or other environmental constraints may have precluded some surveys.
  5. How consistent are the relationships among the observations, including topology?
    The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists.
