Coral cover Jarvis Dataset Description: <p>These data were published in Barkley <em>et al., </em>2018 (Figure 2).</p>
<p>This dataset contains percent coral cover which was collected from photographic surveys conducted along triplicate 50 m transects spanning 5 m to 25 m depth on the east and west side of Jarvis Island in 2015, 2016, and 2017. Jarvis Island is an uninhabited coral reef ecosystem within the US Pacific Remote Islands Marine National Monument (0.37°S, 159.99°W).</p> Methods and Sampling: <p>Repeat transect surveys were conducted at Jarvis during the height of the bleaching event (November 2015), at six months (May 2016), and again at sixteen months (April 2017) post-bleaching. Three 50 m surveyed at each of three depths (shallow: 5-14 m, mid-depth: 15-19 m, and deep: 20-25 m) on the west (all depths: 0.369 ºS, 160.008 ºW) and east sides (shallow: 0.374 ºS, 159.983 ºW, mid and deep: 0.367 ºS, 159.979 ºW) of the island. Each replicate 50 m transect was laid approximately 5 m apart in the cross-shore direction, and a photograph of a 0.5m x 0.5m quadrat taken every meter.</p>

Skeletal Records of Coral Reef Bleaching in the Central Equatorial Pacific

Skeletal Records of Coral Reef Bleaching in the Central Equatorial Pacific
<p><em>NSF Award Abstract:</em><br />
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.</p>
<p>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.</p>

<p>Photographs were analyzed using Coral Point Count with Excel extensions (Kohler and Gill 2006).&nbsp; Benthic cover of each photograph was evaluated by randomly overlaying ten points on each image and identifying the type of cover beneath, with 500 points identified per transect and 1500 points identified per depth. In 2015, random points that fell on live coral were identified as healthy (pigmented tissue) or bleached (non-pigmented living tissue), with the bleached cover calculated as the total number of random points located on bleached tissue divided by the total number of points identified as live (healthy + bleached) coral. In 2016 and 2017, no corals in the transects were still bleached, and were therefore identified as either live or dead.</p>
