Abstract:	During 2016, maximum water temperature in the lagoons of Moorea exceeded a threshold for heat stress for 70 straight days from early February through mid-April. In early May 2016, at the peak of accumulated heat stress, coral bleaching surveys were conducted to test the hypothesis that bleaching prevalence and severity were correlated with differences in heat stress and nutrient availability. This material is based upon work supported by the U.S. National Science Foundation under Grant No. OCE 16-37396 (and earlier awards) as well as a generous gift from the Gordon and Betty Moore Foundation. Research was completed under permits issued by the French Polynesian Government (Délégation à la Recherche) and the Haut-commissariat de la République en Polynésie Francaise (DTRT) (Protocole d'Accueil 2005-2019). This work represents a contribution of the Moorea Coral Reef (MCR) LTER Site.

Description:

We surveyed 167 sites around Moorea and recorded bleaching on colonies of Pocillopora and Acropora, which were present at 149 of the sites. Sites were at least 0.5 km apart, and at each site two snorkelers conducted 10-minute swims in opposite directions recording all observed colonies of Pocillopora and Acropora. Sites were distributed around the entire island, and were categorized by habitat (fringing reef and back reef) and by the dominant cardinal direction of the coastline (North, East, West). We surveyed the two most common and widespread genera of branching corals in the system, Acropora and Pocillopora. The most common Acropora species were Acropora hyacinthus, Acropora retusa, and Acropora clathrata, while the most common Pocillopora species were Pocillopora verrucosa, Pocillopora meandrina, and Pocillopora eydouxi. Pocillopora damicornis and Acropora pulchra were present at some sites but were not included in the surveys since they were largely restricted to the fringing reef sites. For each colony, we estimated the water depth (from 0-3 m deep), and its size class (size classes were 0-10 cm diameter, 11-20 cm, 21-30 cm, 31-40 cm, >40 cm). We then recorded whether bleaching was present (prevalence), and if so, estimated the percentage of the colony surface area that was bleached (severity). Because corals undergo natural, seasonal variation in Symbiodiniaceae density that can affect their coloration, we defined bleached tissue only as tissue that had lost all pigmentation.

To assess nitrogen availability at each site, we measured the N content in the long-lived brown macroalga Turbinaria ornata at each site. The nutrient content of macroalgae is often used as a proxy for ambient nutrient conditions as these macroalgae integrate nutrients over a relatively long time frame (i.e., weeks to months). During January and May 2016, we sampled 10 individual thalli of T. ornata at each site around the island for analysis of N content while we also surveyed coral bleaching (there was minimal bleaching in January 2016). Samples were immediately placed on ice and transported to the lab. One blade from each thallus was sampled at 5 cm below the apical tip of the thallus. These blades were scrubbed of epiphytes and briefly rinsed with fresh water before being dried at 60°C to a constant weight and ground to powder. Total N content was determined via elemental analysis using a CHN Carlo-Erba elemental analyzer (NA1500) CN Analyzer at the University of Georgia, Center for Applied Isotope Studies. We also measured δN15 in the tissues of T. ornata at the Marine Science Institute Analytical Laboratory at the University of California, Santa Barbara, using standard elemental analyzer isotope ratio mass spectrometer (EA-IRMS) procedures. We averaged values from January and May to represent nutrient conditions throughout the Austral summer.

The following is from the NOAA Coral Reef Watch Methodology Page : Coral Bleaching Degree Heating Weeks (DHW) accumulates any HotSpots greater than 1 °C over a 12- week window, thus showing how stressful conditions have been for corals in the last three months. It is a cumulative measurement of the intensity and duration of thermal stress, and is expressed in the unit °C-weeks. DHWs over 4 °C-weeks have been shown to cause significant coral bleaching; values over 8 °C-weeks have caused widespread bleaching and some mortality.
