The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Skeletal cores were collected from Porites coral colonies in April 2010 (n =
4), May 2012 (n = 3), September 2012 (n = 6), November 2015 (n = 16), and May
2016 (n = 1). All cores were collected from colonies at 3-17 m depth using
pneumatic or hydraulic drills with diamond drill bits. Cores collected in 2010
and 2012 were sampled from healthy colonies and were between 50 and 200 cm in
length. In 2015, cores were collected from bleached Porites colonies, and were
limited to 5-10 cm length in accordance with United States Fish and Wildlife
Service permitting restrictions.

Core holes left in the coral colonies were filled with cement plugs, sealed
with underwater epoxy, and secured flush with the existing colony surface.
Visual inspections of coral colonies several years after coring demonstrated
full recovery and complete tissue overgrowth of the cement plug.

Coral skeletal cores, were collected during expeditions aboard:

* NOAA ship Hi\u2019ialakai (2\u20134 April 2010, 3\u20135 May 2012)

* Pangaea Exploration S/V Sea Dragon (13\u201316 September 2012)

* R/V Machias (12\u201315 November 2015)

Research activities and sample collection were conducted under U.S. Fish and
Wildlife Service Pacific Reefs National Wildlife Refuge Complex Research and
Monitoring Special Use Permits:

* 12521-10001 (effective date: 15 Jan 2010; expiration date: 30 May 2010)

* 12521-12001 (effective date: 7 Feb 2012; expiration date: 31 Dec 2012)

* 12521-12005 (effective date: 29 Aug 2012; expiration date: 30 June 2014)

* 12521-14001 (effective date: 1 Jan 2015; expiration date: 31 Dec 2015)

* 12513-15001 (effective date: 11 Nov 2015; expiration date: 31 Dec 2015)

attribute NC_GLOBAL projects_0_description String NSF abstract:
Ocean warming kills corals and efforts are underway to identify and protect coral reefs that may withstand the projected 21st century rise in tropical ocean temperatures. Coral reefs in the central equatorial Pacific (CEP) have been exposed to episodes of extreme warmth every 3-7 years for centuries, if not millennia, yet remain highly productive ecosystems. Initial data obtained by the investigator from stress signatures archived in the skeletons of long lived coral species, suggests that CEP reefs lose their symbiotic algae or bleach, sometimes severely, during warm episodes. The observation that CEP reefs bleach repetitively yet remain productive implies uncommon resilience to ocean warming. The investigator will use laboratory experiments and field observations to validate skeletal records of historical bleaching. A successful outcome will provide novel and valuable insights into the resilience of the CEP reefs and a new tool with which to identify thermally tolerant coral reef ecosystems across the tropics. Additionally, this project includes mentorship of a postdoc and six undergraduate or high school students, outreach through presentations and media, and expansion of publically available software for coral stress band analysis.
Ocean warming projections indicate severe impacts to coral reefs will occur on an annual basis within the next few decades. Consequently, a coordinated effort is underway to identify reefs that might survive these changes. The investigator will test the hypothesis that such reefs exist at the epicenter of influence of the El Niño-Southern Oscillation (ENSO), where strong inter-annual temperature variability creates conditions conducive for the development of thermal resilience. The project uses laboratory-based bleaching experiments and actual stress signatures accreted by wild corals during the 2015 El Niño to validate signatures of historical bleaching archived in the skeletons of massive reef building corals. In addition the investigator will use new, long cores from the CEP to build a robust dataset of historical bleaching back to the 1800's. A successful outcome will increase confidence in the interpretation of skeletal stress bands as quantitative bleaching proxies and enable the reconstruction of the history of coral reef bleaching and recovery in the CEP.

attribute NC_GLOBAL summary String This dataset contains tissue thickness measurements for Jarvis Island coral cores from 2010-2015. Coral tissue thickness, measured as the vertical distance between the top of the core to the most recently accreted dissepiment, was measured on a slice of skeleton cut from the top of each core using a Nikon SMZ1500 stereomicroscope and SPOT imaging software.
