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.

The Biophysics of Coral Reef Resilience: hydrodynamic and ecological drivers of coral survival under extreme heat http://www2.whoi.edu/site/cohenlab/ The Biophysics of Coral Reef Resilience: hydrodynamic and ecological drivers of coral survival under extreme heat <p><em><strong>NSF Award Abstract:</strong></em><br /> Coral reefs are among the most diverse ecosystems on the planet and support the livelihoods of hundreds of millions of people around the world. Ocean warming and intensifying heatwaves are killing coral reefs and there are urgent efforts underway to identify and protect those capable of surviving future warming. Coral reefs in the central equatorial Pacific have experienced three extreme heat events over the last two decades. Initial observational data obtained by the investigators show that coral mortality during each event was spatially variable, implying that some coral communities have developed resilience to thermal stress. In this study, the investigators are examining the role of fine-scale variations in reef temperature and water flow in promoting coral resilience by providing opportunities for genetic adaptation, by protectively cooling corals through upwelling or internal waves, or by enhancing food supply. Results will provide novel insights into the mechanisms by which coral communities survive extreme heat and a new tool that allows scientists and coral reef managers to identify resilient reefs for protection. Additionally, this project is supporting an early-career scientist, graduate and undergraduate research, opportunities for high school students in the United States to participate in research, as well as participation by Kanton high school students. Outreach will be conducted through presentations and a variety of media, including film. The hydrodynamic model output will be made publicly available, and project outcomes will contribute to a universal map of coral thermal thresholds currently under development by the scientific community.</p> <p>Ocean warming and intensifying heatwaves are devastating coral reefs across the global tropics. Consequently, a coordinated effort is underway to identify and protect coral communities that can survive these changes. This interdisciplinary team of investigators is combining oceanographic observations, 3-dimensional fine-scale hydrodynamic model simulations, benthic surveys, and biological assays to investigate the role of reef hydrodynamics in facilitating coral resilience to thermal stress on Kanton Island in the central equatorial Pacific. The investigators are testing the hypothesis that oceanographic and atmospheric forcing interact with reef bathymetry to induce predictable fine-scale heterogeneity in water temperature and flow across the reef. They are also testing the hypothesis that environmental heterogeneity, in turn, facilitates coral survival of extreme heat by providing opportunities for genetic adaptation, protective cooling, and/or enhanced food supply. Results will provide insights into the biophysical mechanisms underpinning reef resilience and a new tool with which to predict resilience across a broad range of coral reef ecosystems.</p> <p>This project is supported with funds from the Biological and Physical Oceanography Programs.</p> <p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p> Biophysics of Coral Reef Resilience largerWorkCitation project eng; USA oceans 131.843 134.69 2.95346 8.03909 1970-01-01 2014-12-31 Central Tropical Pacific 0 BCO-DMO catalogue of parameters from Average yearly extension rate, calcification rate, and density for each core sample from Porites cf. lobata coral at Palau's Rock Islands Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/894951.rdf Name: Sample Units: unitless Description: <p>Identifier code for sample</p> http://lod.bco-dmo.org/id/dataset-parameter/894952.rdf Name: Site Units: unitless Description: <p>The name of the reef at which the sample was taken</p> http://lod.bco-dmo.org/id/dataset-parameter/894953.rdf Name: Lat Units: decimal degrees North Description: <p>latitude of location</p> http://lod.bco-dmo.org/id/dataset-parameter/894954.rdf Name: Long Units: decimal degrees East Description: <p>longitude of location</p> http://lod.bco-dmo.org/id/dataset-parameter/894955.rdf Name: Core Units: unitless Description: <p>Identifier code for the physical coral core (differs from Sample name)</p> http://lod.bco-dmo.org/id/dataset-parameter/894956.rdf Name: Year Units: unitless Description: <p>Year of coral growth</p> http://lod.bco-dmo.org/id/dataset-parameter/894957.rdf Name: Density Units: grams per cubic centimeter (g cm-3) Description: <p>Average density of core during the designated year of growth</p> http://lod.bco-dmo.org/id/dataset-parameter/894958.rdf Name: ExtRate Units: centimeters per year (cm y-1) Description: <p>Average extension rate of core during the designated year of growth</p> http://lod.bco-dmo.org/id/dataset-parameter/894959.rdf Name: CalcRate Units: grams per square centimeter per year (g cm-2 y-1) Description: <p>Average calcification rate of core during the designated year of growth</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 92703 https://darchive.mblwhoilibrary.org/server/api/core/bitstreams/2a9881b4-8ffd-4bd9-8b12-5a8b38d3dc16/content download https://doi.org/10.26008/1912/bco-dmo.894930.1 download onLine dataset &lt;p&gt;Samples were collected from coral reefs of Palau's Rock Islands.

There are many types of drills: some are powered manually, and others use electricity (electric drill) or compressed air as the motive power. Drills with a percussive action (hammer drills) are mostly used in hard materials such as masonry (brick, concrete, and stone) or rock. Some types of hand-held drills are also used to drive screws and other fasteners.
