Abstract: Abstract written by OBIS-USA using excerpts from CRED homepage.
Corals are the defining species in one of the highest diversity marine ecosystems, coral reefs. CRED studies of corals address basic questions concerning the distribution, abundance, and condition of corals and coral reefs throughout selected areas of the tropical and subtropical Pacific under U.S. jurisdiction.
The suite of ... questions addressed by CRED studies includes:
(1) What is the diversity and relative abundance of corals?
(2) How can the habitats in which corals occur be qualitatively and quantitatively analyzed?
(3) What is the spatial distribution of habitats in which corals occur?
(4) What is the capacity of corals to replenish populations over space and time?
(5) What are appropriate indicators of reef health?
(6) Are the reefs healthy?
(7) How are the reefs changing over time?
Several methods are used to address these questions. Any one method can address only a certain subset of questions; no one method can address them all. Methods used by CRED and its partners include towed diver surveys, Rapid Ecological Assessments (REAs), permanent transects, recruitment plates, and sampling for assessment of reproductive status.
Purpose: The mission of the Coral Reef Ecosystem Division is to provide sound science to enable informed and effective implementation of ecosystem-based management and conservation strategies for coral reef ecosystems of the U.S.-affiliated Pacific Islands Region. To accomplish this mission, the Division leads an integrated, interdisciplinary program of ecosystem assessment and long-term monitoring, ... benthic habitat mapping, and applied research on the coral reef ecosystems of 50 primary islands and atolls in the Hawaiian Archipelago, the Mariana Archipelago (Guam and the Commonwealth of the Northern Mariana Islands), American Samoa, and the Pacific Remote Island Areas (PRIA). The Division's work supports NOAA and other agencies in meeting mandates of the Coral Reef Conservation Act of 2000 and various executive orders issued to ensure conservation and protection of the nation's coral reef ecosystems.

DISTRIBUTION LIABILITY: OBIS-USA renders information prepared by contributors accessible through dynamic on-line publication. It does not peer-review the quality of the data provided. However, ... it is confident that the data are the best available in electronic form. OBIS-USA does not own or try to control or limit the use of any data or products accessible through its website.

Users must recognize that the analysis and interpretation of data requires background knowledge and expertise about marine biodiversity (including ecosystems and taxonomy). Users should be aware of possible errors in the use of species names, geo-referencing, data handing and mapping. They should crosscheck their results for possible errors, and qualify their interpretation of any results accordingly. Appropriate caution is thus necessary in the interpretation of results derived from OBIS-USA.
Use Constraints Prior to use of these records in any analysis or report, the Coral Reef Ecosystem Division (CRED) of the Pacific Island Fisheries Sciences Center must be notified and if used the provenance of the original data must be acknowledged.
