Data are from an 18-month field experiment on the fore reef of Moorea, testing how different forms of nitrogen (nitrate vs. urea) impact coral bleaching and mortality during two mild thermal stress events in the Austral summers of 2016 and 2017. These data are associated with a manuscript currently in review at Ecosystems. Tentative mansucript title and author list are: Nitrogen source drives differential impacts of nutrients on coral bleaching prevalence, duration, and mortality Deron E. Burkepile, Andrew A. Shantz, Thomas C. Adam, Katrina S. Munsterman, Kelly E. Speare, Mark C.

Caged tiles were placed at various sites to measure short-term algal accumulation in the absence of grazing by fishes or large invertebrates. These data document biomass of algae that accumulated on unglazed ceramic tiles (2.5 cm X 2.5 cm) placed inside cages (mesh size = 2.5 cm x 2.5 cm) at various sites around the island of Moorea for a period of 3 to 4 weeks. Three separate experiments were conducted (one during July-August 2010 and two in July-August 2011).

These data were generated from a one-time experiment in support of a coral ecophysiology manuscript; published in Marine Biology. Edmunds (2012) Marine Biology 159: 2149-2160 doi:10.1007/s00227-012-2001-y The hypothesis that was tested stated that high pCO2 (76.6 Pa and 87.2 Pa vs. 42.9 Pa) has no effect on the metabolism of juvenile massive Porites spp. after 11 days at 28 °C and 545 lmol quanta m-2 s-1. The response was assessed as aerobic dark respiration, skeletal weight (i.e., calcification), biomass, and chlorophyll fluorescence.

For many marine invertebrates, the maximum size of an individual is influenced heavily by environmental factors and may be limited by energetic constraints. In this study, an energetic model developed originally for anemones was applied to the free-living scleractinian Fungia concinna (Verrill) from Moorea, French Polynesia to test the hypothesis that energetic constraints limit the size of this solitary coral.

Samples of two common macroalgal species (Sargassum mangarevense, Turbinaria ornata) are collected yearly from fringing, backreef, and reef crest sites at each of the sites (LTER 1 through LTER 6) around Moorea. CHN analyses of dried, ground samples of each individual are made using standard methods. CHN data are used to track sustained variation in nutrient availability. Water column nutrients in coral reef systems usually are low to undetectable and their inputs tend to be episodic and ephemeral.

Rates of community primary production and respiration can be calculated from the data presented here. For two sites on the north shore of Moorea, these measurements are sampled upstream and downstream: dissolved oxygen, water column velocity (speed and direction), in situ light (PAR) levels, incident solar radiation, temperature, wind speed, and transect length. Estimates are made yearly across approximately 160 m of the backreef community.

This data package contains measurements of the sedimentation rate of particulate matter to the seafloor on the forereef, backreef and fringing reef of the north shore of Moorea, French Polynesia, during 2 to 4 seasons per year from August 2005 to January 2011. Measurements include estimates of the accumulation rate of particulate organic carbon (POC), particulate organic nitrogen (PON), and dry mass. Samples were collected with 2 different types of sediment traps.
