OAP Projects in the NORTHEAST U.S.


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.

OA products for the Gulf of Mexico and East Coast

Ruben van Hooidonk and Rik Wanninkhof, AOML

Dedicated research cruises are used to obtain subsurface measurements and a comprehensive suite of biogeochemical observations to gain a process level understanding of OA. OAP provides funds to carry out the Gulf of Mexico and East Coast Carbon (GOMECC) research cruises every 5 years. These cruises provide a data set of unprecedented quality of physical and chemical coastal ocean parameters that is used both for improved spatial understanding of OA and also to provide a general understanding of changing patterns over time by comparison with previous cruises. The monitoring component is an essential part of the OAP, providing a long-term assessment of changes of biogeochemistry and ecology in response to increasing CO2 atmospheric levels and large-scale changes in coastal dynamics.

The climate quality data from the research cruises provide an important link to the Global Ocean Acidification Network (GOAN) effort, and contribute to a long-term record of dynamics and processes controlling OA on the coastal shelves. The data are used for validation measurements of autonomous assets, applying the data 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.
