MCR LTER: Coral Reef: Early life stage bottleneck determines rates of coral recovery following severe disturbance; Data for Speare et al., 2024, Ecology

The data included in this data package were collected on the north shore of Moorea, French Polynesia, from 2011-2018 to evaluate drivers of different recovery rates of corals at two depths (10m and 17m). Data on juvenile coral densities, growth, and mortality, were collected from annual time series photoquadrats. Data from two experiments on coral settlement tiles were used to evaluate how exclusion of fishes influences the density of coral recruits, and the survival of coral recruits at 10 and 17m.

MCR LTER: Coral Reef: Quantifying 2019 coral bleaching; data for Kopecky et al., 2023 Remote Sensing

This data package contains a dataset generated using image AI-assisted image segmentation of live and dead corals within ortho-photomosaics of benthic reef habitat on the North shore fore reef of Moorea, French Polynesia. The orthophotomosaics were produced through a rigorous method of underwater photogrammetry that allowed for spatial and temporal co-registration of ortho-photomosaics of the same location over time (for full photogrammetric methods, see Nocerino et al. 2020: https://doi.org/10.3390/rs12183036). Using the image segmentation software, TagLab (see Pavoni et al.

MCR LTER: Coral Reef: 3D photogrammetry improves measurement of growth and biodiversity patterns in branching corals; data for Curtis 2023, Coral Reefs

These data and code were generated in support of the manuscript: Curtis JS, Galvan JW, Primo A, Osenberg CW, and AC Stier, Coral Reefs. We collected manual and photogrammetry-based measurements of coral size and volume to examine which method best described short-term coral growth and links between coral habitat and biodiversity of CAFI (coral-associated fishes and invertebrates).

MCR LTER: Coral Reef: Asynchrony in coral community structure contributes to reef‑scale community stability, data for Srednick et al., Nature 2023

These data were generated in support of the manuscript: Srednick G, Davis K, and Edmunds P, Nature To evaluate whether spatial insurance effects are important on coral reefs, we explored variation over 2006–2019 in coral community structure and environmental conditions in Moorea, French Polynesia. We studied coral community structure at a single site with fringing, back reef, and fore reef habitats, and used this system to explore associations among community asynchrony, asynchrony of environmental conditions, and community stability.

MCR LTER: Coral Reef: Coral bleaching with nitrogen and heat stress: 2016 data in support of Donovan et al. submitted to PNAS

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.

Rosman, in press, Collapsing complexity: metrics to quantify multi-scale properties of reef topography.

MCR LTER: Coral Reef: Coral size, temperature and turbulence data in support of Edmunds and Burgess MarBio 2017

In this study, we tested the effects of colony size and seawater turbulence on the response of the common Indo-Pacific branching coral, Pocillopora verrucosa, to different seawater temperatures. Using whole-colony calcification as a response variable, 12 tanks (each 150 l) were used in two trials lasting 14 days to contrast the effects of seawater turbulence (two levels) and temperature (25.5°C vs 29.5°C) on colonies varying in size from ~4 to 13-cm diameter.

MCR LTER: Coral Reef: Recruitment during El Niño, Edmunds PLOS1 2017

The negative implications of the thermal sensitivity of reef corals became clear with coral bleaching throughout the Caribbean in the 1980’s, and later globally, with the severe El Niño of 1998 and extensive seawater warming in 2005. These events have substantially contributed to declines in coral cover, and therefore the El Niño of 2016 raised concerns over the implications for coral reefs; on the Great Barrier Reef these concerns have been realized.

MCR LTER: Coral Reef: Coral Growth in Temperature and Alkalinity Treatments: Edmunds 2011 Limnology & Oceanography

Edmunds, PJ (2011) Limnology and Oceanography 56: 2402-2410 doi: 10.4319/lo.2011.56.6.2402 I tested the hypothesis that the effects of high pCO2 and temperature on massive Porites spp. (Scleractinia) are modified by heterotrophic feeding (zooplanktivory). Small colonies of massive Porites spp. from the back reef of Moorea, French Polynesia, were incubated for 1 month under combinations of temperature (29.3 C vs. 25.6 C), pCO2 (41.6 vs. 81.5 Pa), and feeding regimes (none vs. ad libitum access to live Artemia spp.), with the response assessed using calcification and biomass.

MCR LTER: Coral Reef: Water Column: Bay Water Profiles: CTD Transects

This dataset contains vertical water column profiles along transects in Opunohu Bay and Cook’s Bay on the north side of Moorea. The SeaBird SBE19-Plus Profiler (CTD), outfitted with WetLabs FLNTURT-221 fluorometer, was cast at closely-spaced stations along transects down the length of the bays. Standard CTD parameters (conductivity, temperature, and density) were used to calculate salinity, depth, and other physical quantities. No bottle samples were collected on these cruises. Profiles in the bays were obtained when sea conditions offshore prohibited sampling over the forereef.

MCR LTER: Coral Reef: Water Column: Offshore Water Profiles: CTD Transects

This dataset contains vertical water column profiles along transects heading offshore over the forereefs on the three sides of Moorea. These sides are designated north, southeast, and southwest. This process study intended to look for a hypothesized buoyant flow that would account for the counter-clockwise (CCW) circulation around the island. These transects were designed to look for cross-shore density gradients associated with the CCW flow.

MCR LTER: Coral Reef: Sensor Network: Bottom-mounted CTD Data - GUMPR, 2006-2012

Physical oceanographic data from bottom-mounted instrumentation (Seabird 16+ CTD) were sampled year-round on Gump reef in Cooks Bay on Moorea, French Polynesia (GUMPR site). Sampling began in 2006 until early 2012. The CTD measured conductivity, temperature, pressure, from which density and salinity were calculated. Data were collected every 5 minutes, processed and reported every 20 minutes. The instrument is mounted 2 m above the bottom in 6 m of depth.
