MCR LTER: Coral Reef: Data in support of Wall and Edmunds 2013 Biological Bulletin, v225 no. 2, 92-101

These data were generated from a one-time experiment in support of a coral ecophysiology manuscript published in The Biological Bulletin. Wall and Edmunds (2013) The Biological Bulletin vol. 225 no. 2: 92-101 Juvenile colonies of massive Porites spp. were exposed to manipulated pH and bicarbonate ([HCO3 -]) in situ to test the hypothesis that ocean acidification (OA) does not affect respiration and calcification. Incubations lasted 28 h and exposed corals to ambient temperature and light with ecologically relevant water motion.

MCR LTER: Coral Reef: Porites growth, respiration, and photophysiology data in support of Edmunds 2012 Marine Biology, v159, 2149-2160

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.

MCR LTER: Coral Reef: Data in support of Edmunds 2012 Global Change Biology, v18 2173-2183

These data were generated from a one-time experiment in support of a coral ecophysiology manuscript; published in Global Change Biology 2012. Edmunds et al. (2012) Global Change Biology 18: 2173-2183 doi:10.1111/j.1365-2486.2012.02695.x These data were collected to test the hypothesis that the response of corals to temperature and pCO2 is consistent between taxa. Juvenile massive Porites spp. and branches of P.

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.

MCR LTER: Coral Reef: Patterns and implications of spatial covariation in herbivore functions on resilience of coral reefs

These data and code were generated in support of the manuscript: Cook DT, Holbrook SJ, and Schmitt RJ, Scientific Reports. In 2017, we collected biological and physical data from 20 sites along the north shore of Moorea, French Polynesia, to investigate spatial patterns in grazing and browsing functions of herbivorous fishes, environmental correlates, and implications for coral resilience.

MCR LTER: Coral Reef: coral mortality in the lagoon of Moorea in 2019

The data included in this data package were collected in the lagoon of Moorea, French Polynesia. Data on coral mortality were collected in July 2019. Data on nitrogen content (%N) in the long-lived brown macroalga Turbinaria ornata were collected during six sampling campaigns between January 2016 and May 2021 to characterize nitrogen availability at each site. Data on seawater temperatures at six LTER sites in the back reef were collected from 2005-2019, but temperature loggers at two sites (LTER 1 and LTER 6) only recorded partial ocean temperature records during the heatwave from 2018-2019.

MCR LTER: Coral Reef: Dead coral skeletons impair key recovery processes following coral bleaching; data for Kopecky et al., 2024 Global Change Biology

The data included in this data package were collected on the North shore of Moorea, French Polynesia, from 2015-2023 to explore how dead coral skeletons (e.g,, left after coral bleaching events) influence critical processes tied to coral reef resilience.

MCR LTER: Coral Reef: Modeling the effects of selectively fishing key functional groups of herbivores on coral resilience; data for Cook et al., 2023 Ecosphere

These data and code were generated in support of the manuscript: Cook DT, Schmitt RJ, Holbrook SJ, and HV Moeller, Ecosphere. To investigate the impacts of selectively harvesting functional groups of herbivorous fishes on coral resilience, we used a dynamic model that is grounded by the coral reef system in Moorea, French Polynesia. Our model simulates the fraction of a reef occupied through time by classes of key benthic spaceholders (coral, two stages of macroalgae, and turf). Benthic and fishing dynamics are linked through the harvesting of two functional groups of herbivorous fishes.

MCR LTER: Coral Reef: Material legacy disturbance type model; data for Kopecky et al., 2023 Ecology

This data package contains the code necessary to create a mathematical model of coral reef recovery dynamics following different types and intensities of disturbances that either remove dead coral skeletons (e.g., tropical storms) or leave standing dead skeletons (e.g., coral bleaching) and run associated analyses. We explored the sensitivity of the model to variation in key parameters, such as the strength of herbivory, and the degree to which dead skeletons protect algae from herbivory.

MCR LTER: Coral Reef: pH Time Series from Bottom-mounted SeaFET on the Fringing Reef, January-February 2011

Bottom-mounted instrumentation (SeaFET, Seabird thermistors) sampled for 6 weeks on the fringing reef of Moorea Island, French Polynesia at site LTER Fringe 1. Sampling began in January 2011. The instruments were secured to a cement piling at 3.3 meters depth and 0.7 meters above the sandy bottom. The SeaFET recorded voltages from a thermistor and pH electrodes at a 10-minute sampling interval.

MCR LTER: Coral Reef: Island-Wide Lagoon Benthic Water Temperature, ongoing since 2021

Beginning in August 2021, a continuous time series of benthic water temperature is measured with bottom-mounted thermistors (SBE 56s) at 49 sites around the lagoons of Moorea. The thermistor array consists of a backbone of 36 thermistors placed on the backreef approximately 200 m shoreward of the reef crest and spaced approximately 1 km apart. In addition, there are three cross-shore transects (one on each of the three sides of the island). Each cross-shore transect consists of five bottom-mounted thermistors spaced at 100 m intervals, starting at the reef crest and ending 400 m inshore.

MCR LTER: Coral Reef: Temperature and Salinity subset of moorings FOR01, FOR04 and FOR05 from 2005-2014

This dataset is derived as a subset from three separate much larger more complex datasets: knb-lter-mcr.30, knb-lter-mcr.31, and knb-lter-mcr.32. Sampling began in 2005 and continues (as of 2019) for those time series. This dataset knb-lter-mcr.1040 was an experimental workflow that ended with 2014 data. Moored instrumentation measures water temperature and salinity year-round on the forereef of Moorea, French Polynesia at sites FOR01, FOR04 and FOR05 on the forereef of the north, east, and west shores, respectively. Data are interpolated onto a 20 minute grid.

MCR LTER: Coral Reef: Water Column: Offshore Ocean Acidification: Water Profiles, CTD, and Chemistry from 2005 to 2012

This data package contains water chemistry measurements taken 2 to 4 times per year at a station 5 km offshore of the north shore of Moorea, French Polynesia. Measurements include standard CTD parameters, phosphate, silicate, total alkalinity (TA) and total dissolved inorganic carbon (DIC). Sampling began in August, 2005. All water samples were collected with Niskin Bottles. This data includes excerpts from CTD data were collected with a SBE19-Plus Seacat Profiler. CTD and bottle samples were taken on separate casts at each station. (For full CTD data refer to knb-lter-mcr.10.)

MCR LTER: Coral Reef: Bathymetry Grid for North Shore

These bathymetric data are a combined product of digitized SHOM nautical charts, SRTM30plus bathymetry, small boat surveys, and bathymetry derived from Worldview-2 satellite imagery. Satellite data were collected in collaboration with Le centre de L'Environment de Moorea (CRIOBE). Data products are (x,y,z) point data and images in Coordinate system: UTM zone 6S and Datum: WGS-84.

MCR LTER: Coral Reef: Benthic Water Temperature, ongoing since 2005

A continuous time series of benthic water temperature is measured with bottom-mounted thermistors at six sites around the shores of Moorea, on the fringing reef, backreef, and forereef. The forereef temperature is recorded with SBE 39s or SBE 56s at 10, 20, 30 and 40 m, starting between 2005 to 2007, except FOR00 starting in 2010. These are ongoing except the 40 m deployments were discontinued after August 2019. The backreef SBE 39s/56s are mounted on plates at 1 m depth at LTER 1 and at 2 m depth at the other five sites.

MCR LTER: Coral Reef: Ocean Currents and Biogeochemistry: Moored Thermistor String Data - CBYTS; from 2005 to 2011

A vertically moored thermistor string sampled year-round on the reef at Cook's Bay in Moorea, French Polynesia. Sampling began in 2005 and ended in August 2011. All data have been interpolated onto a 20 min grid. Thermistors were spaced vertically along the mooring line 4, 8, 12, 16, and 20 meters above the bottom. Pressure measurements are also provided from two of the instruments typically located at 4 and 20 meters above the bottom.

MCR LTER: Coral Reef: Ocean Currents and Biogeochemistry: salinity, temperature and current at CTD and ADCP mooring FOR05 from 2005 ongoing

Moored and bottom-mounted instrumentation (ADCP, CTD, thermistors, wave-tide meters) sampled year-round on the reef of Moorea Island, French Polynesia at LTER 5 fore reef site (FOR05). Sampling began in 2005. All data have been interpolated onto a 20 min grid. ADCP data are organized into 1-meter bins, measured as height from the bottom, to a maximum of 20 bins. All bins may not be filled, and although post-processing attempted to exclude data from bins 'above the surface', users need to exercise caution with the near-surface bins.
