East Coast OA (ECOA) Cruise

Joe Salisbury (University of New Hampshire) & Wei-Jun Cai (University of Delaware)

NOAA academic partners Salisbury and Cai will organize and lead a 34-days cruise covering 12 transects of the U.S. and Canadian coast oceans from Nova Scotia in the north to the Gulf of Maine, Long Island Sound, Mid-Atlantic and Southern Bight regions, ending with a transect off of mid Florida. This cruise will serve as a synoptic characterization of the marine carbonate parameters of the coastal ocean with increased coverage in nearshore areas that have not surveyed in the previous cruises and subsurface dynamics that are not captured from using buoyed assets or ships of opportunity. The climate quality data from these cruises provide an important link to the Global Ocean Acidification Network (GOAN) effort, and serves as a start of a long-term record of dynamics and processes controlling Ocean Acidification (OA) on the coastal shelves. To this end there is an increasing focus on these cruises to perform rate measurements (e.g. NPP/NEP/NEC) for validation measurements of autonomous assets and buoyed assets, for algorithm development utilizing remotely sensed signals that are used to characterize saturation states, and to project the future state of ocean acidification in the project area.

Service and Maintenence of the Gray's Reef OA Mooring

Wei-Jun Cai & Scott Noakes

This project will provide service and maintenance of sensors and ground-truthing of the mooring data at the Gray's Reef OA monitoring site, as well as data quality control and synthesis. Specifically, we will accomplish the follow three tasks: 1. Deployment and maintenance of the sensors (pCO2, pH, and dissolved oxygen); 2. Collection of underway pCO2 data and bulk water samples for analyses using ship-of-opportunity and dedicated cruises about four times a year; and 3. Data quality control and data synthesis.

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.

NCRMP – OA Enterprise

Jessica Morgan, Derek Manzello, Adrienne Sutton, Charles Young

NCRMP‐OA is a Joint Enterprise designed to address the Tier 1 Ocean Acidification (OA) components of the larger NCRMP strategic framework at Class 0, II, and III stations. Field work and laboratory analyses for the Atlantic/Caribbean region (Florida, Puerto Rico, U.S. Virgin Islands [USVI], and Flower Garden Banks [FGB]) are executed by the OAR Atlantic Oceanographic and Meteorological Laboratory (AOML) and by the University of Puerto Rico (UPR) Caribbean Coastal Ocean Observing System (CariCOOS). Field work in the Pacific region (Main Hawaiian Islands [MHI], Northwestern Hawaiian Islands [NWHI], Guam, Commonwealth of the Northern Mariana Islands [CNMI], American Sāmoa, and the Pacific Remote Island Areas [PRIA]) is executed by the NMFS Pacific Islands Fisheries Science Center [PIFSC] Coral Reef Ecosystem Division (CRED); laboratory analyses for the Pacific region are executed by the OAR Pacific Marine Environmental Laboratory (PMEL). NCRMP‐OA Teams closely coordinate with other NCRMP elements (benthic, fish, water temperature, satellite, and socioeconomic teams), including PMEL’s NOAA Ocean Acidification Observing Network (NOA‐ON), other NOAA offices, Federal, State, and Territory agencies, and academic partners, in both the Atlantic and Pacific regions.  

This project monitors changes to coral reef carbonate chemistry over time, at US affiliated coral reef sites, through quantifying key chemical parameters that are expected to be impacted by ocean acidification. This effort addresses OAP programmatic themes 1 and 5 by maintaining the coral reef portion of the OA monitoring network and developing a procedure for data synthesis, assimilation, and distribution. Incorporating an interdisciplinary approach, this project will collect, process, analyze, and steward dissolved inorganic carbon (DIC) and total alkalinity (TA) water sample data to document seawater carbonate chemistry at Class 0, II, III climate monitoring sites in coral reef areas of the US Atlantic and Pacific regions.
