Science Objectives | |
| The PEACH project will identify the processes that control the exchange of waters between the shelves along the eastern seaboard of the US (Middle Atlantic Bight and Southern Atlantic Bight) and the open ocean. The processes will be investigated to determine the dominant forcing mechanisms (e.g., Gulf Stream, atmosphere, buoyancy). The understanding of shelf-deep ocean exchange gained through PEACH will be applicable to other regions where shelf and basin-scale currents converge. The detailed examination of shelf response made possible by the sampling scheme, the dynamical understanding achieved by a coupled observation-model exploration of dynamics, and the simulation skill developed over the wide seasonal and interannual variation in forcing will transform our capacity to anticipate the response of the coastal ocean to forecasted climatic evolution of forcing in the coming decades. | |
Science Activities | |
Steam cross-shelf to Pioneer Array, then transit directly to study area near Cape Hatteras. At the study-site (exact order of operations is strongly weather dependent) turn around moorings and conduct a CTD cast at each site. - Turn around 2 met-moorings (at sites B1 and B2) in 30 m of water. During each turn around, a small boat may be required so the techs can climb on the mooring to re-connect the battery and set the antenna. - Turn around 5 ADCP moorings (at sites B1, B2, A1, A2, A3) in water depths ranging from 30 m to 100 m. If releases do not work for ADCPs near B1 and B2 dive operations may be necessary to recover instruments - Complete a bathymetric survey near Cape Hatteras that was half completed in April - Conduct high-horizontal resolution CTD transects across features of interest to be determined real-time via satellite info from SSH and SST as well as glider data (i.e. eddies, shelfbreak front). This may extend into the transit home.
During the transit from the study-site home to Woods Hole - complete any CTD feature transects - Cross-shelf CTD section from Pioneer Array to 40 m isobath | |
