ONR Ship Time and Marine Technician Support for the RV Endeavor - CY 2018
Abstract
The Research Vessel Endeavor is owned by the National Science Foundation (NSF) and has been operated and managed by the University of Rhode Island’s Graduate School of Oceanography since 1976 in support of our nation’s oceanographic science community. This proposal requests funds for two ONR sponsored science missions aboard the R/V Endeavor during CY 2018. 1). Atlantic Deepwater Ecosystem Observatory Network (ADEON): An Integrated System Principle Investigator: Jennifer Miksis-Olds (University of New Hampshire) Deploy 7 long-term moorings with passive acoustics and full complement of oceanographic and met measurement systems. These moorings will be nominally distributed over a 1000 km line along the 1000 m isobath in the Outer Continental Shelf area of the Atlantic off the southeast of the US. The moorings will be deployed and tested over 2-3 weeks. Long-time series data will be collected over multiple years. After initial deployment it is anticipated that each mooring will need to be visited for serving every 6-12 months. Five research cruises will occur throughout this project at regularly scheduled intervals (Fall 2017, Spring 2018, Fall 2018, Fall 2019 and Fall 2020) to recover and redeploy moorings, launch and recover the HLA glider, and to collect ship-board data for ground-truthing, for inter-calibration of mooring data, and for examination of spatial and temporal patterns in ocean sound and the distribution/abundance of biological organisms in the study region. Cruises approximately two weeks in duration will employ a combination of station sampling (CTD casts, net tow) at each mooring site, as well as fine-scale lawn-mower pattern transect sampling covering an area roughly 18 km by 18 km around each mooring site. Additional transect and station sampling will occur during transits between mooring sites (to further characterize cross-shelf, cross-Gulf Stream, and latitudinal gradients) as conditions and time permit. The glider path plan will be designed ahead of time carefully combining mooring location, ship operations schedule, location of the Gulf Stream, and local currents. High-resolution remote sensing data will be acquired prior to and during each cruise to direct cruise sampling and provide synoptic ancillary data over the entire study region. Level of Support: 43 Days 2.) Secure and robust underwater acoustic networking while under passive and active attacks Principle Investigator: Zhiqiang Liu (Naval Research Laboratory) Deploy/recover multiple acoustic modem moorings from RV Endeavor.
