Average yearly extension rate, calcification rate, and density for each core sample from Porites cf. lobata coral at Palau's Rock Islands from 1970-01-01 to 2014-12-31 (NCEI Accession 0291938)

This dataset contains biological, chemical, and physical data collected in the North Pacific Ocean and Philippine Sea from 1970-01-01 to 2014-12-31. These data include calcification, density, and growth. The instruments used to collect these data include Computerized Tomography (CT) Scanner and Drill. These data were collected by Anne L. Cohen and Hanny Rivera of Woods Hole Oceanographic Institution as part of the "The Biophysics of Coral Reef Resilience: hydrodynamic and ecological drivers of coral survival under extreme heat (Biophysics of Coral Reef Resilience)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-05-23.

Palau Coral Growth

Dataset Description:
Acquisition Description:
Samples were collected from coral reefs of Palau's Rock Islands. Coral cores (N = 121) were taken using an underwater pneumatic drill equipped with a diamond-tipped drill bit powered by compressed air from a SCUBA tank. Cores ranged from 10 to 204 centimeters (cm) long, covering years from 1970 to 2014. Cores were dried in an oven and imaged using a Volume Zoom Helical Computerized Tomography (CT) Scanner at Woods Hole Oceanographic Institution. Scans were analyzed using an automated computer program. Cores that displayed high levels of bioerosion, inconsistent banding patterns, partial mortality, or other deformities preventing accurate identification of annual growth bands, and as a result, correct identification of years corresponding to bleaching events, were excluded from analysis (N = 42). Of the remaining 80 cores, 11 had unsuccessful DNA extractions or failed other downstream genetic data filters, leaving 69 corals for final analyses. Coral samples were imported to the U.S. under CITES permit numbers: PW14-163, PW15-022, PW18-121. RAD-sequencing data are available in the National Center for Biotechnology Information (NCBI) Sequence Read Archive (SRA) under accession number PRJNA801929.
