OAP PRojects IN CORAL REEF ECOSYSTEMS


Building Robust Reef Carbonate Projections from Synthesized NCRMP Ocean Acidification Datasets

Tom Oliver and Derek Manzello, NOAA Coral Reef Conservation Program

This project will serve to (1) synthesize National Coral Reef Monitoring Program (NCRMP) OA Enterprise observations; (2) compare reef OA observations to oceanic end members to infer reefscale biogeochemical processes, and finally (3) use these synthesis products to better link projection models of oceanic carbonate systems to reef-scale OA impacts. The NCRMP OA enterprise supports: our collection of seawater samples from reef and surface observations; a set of MapCO2 buoys in the Caribbean and Hawaii; diurnal monitoring instruments (e.g. CREP's diurnal suite, AOML's/McGillis' BEAMS); and metrics of ecosystem response to OA (e.g. CAUs, coral coring, etc.). The datasets generated by these activities will be the focus of this wide-ranging synthesis.

Effects of elevated pCO2 and temperature on reef biodiversity and ecosystem functioning using Autonomous Reef Monitoring Structures and hyperspectral technology

Molly Timmers, NOAA Coral Reef Conservation Program

The goal of this project is to improve our understanding of the effects of ocean acidification and warming on coral reef communities by examining responses of entire suites of reef organisms recruiting to Autonomous Reef Monitoring Structures (ARMS) in benthic mesocosms. We will perform a fully factorial experiment that consists of four treatments of low and high temperature and pCO₂ levels. ARMS are the leading long-term monitoring tool to measure biodiversity on reef systems and are integrated into the National Coral Reef Monitoring Program (NCRMP) Class II and Class III climate stations dedicated to monitor and access the physical, chemical and biological impacts associated with climate change over time. We propose to examine the effects of elevated temperature and pCO₂ on recruitment, biomass, biodiversity, and community structure over a multiannual time frame to increase our understanding of how biodiversity, ecosystem function, and their relationship will be impacted under future climate scenarios.
