MCR LTER: Coral Reefs: Coral bleaching and mortality in July 2019; data for Speare et al. 2021 Global Change Biology

These data are from field surveys conducted at seven sites at 10m depth on the outer reef of Mo’orea following a marine heatwave and coral bleaching event in the Austral Summer of 2019. These data describe the size, percent of the colony that was bleached, and the percent of the colony that recently dead for corals in the genera Acropora and Pocillopora. At six sites (LTER 1-6) coral colony size was quantified using ordinal size bins and observers collected data on all coral colonies > 5cm diameter. At one site on the north shore of Mo’orea (LTER Experimental Site) coral colony size was measured to the nearest centimeter. At this site researchers did two separate sets of surveys, one to collect data on all corals > 5cm diameter, and one to collect data on all individuals ≤ 5cm diameter. Additionally, data on survivorship of newly-settled coral recruits on coral settlement tiles are included. Tiles were deployed at 10m depth at one site on the outer reef of Moorea. Survivorship of coral recruits between March and July was assessed in 2017 and 2019. These data are in support of a publication Speare et al. (2021) Global Change Biology.
