This research was funded by the Carolinas Coastal Change Project, a study supported by the USGS Coastal and Marine Geology Program. We thank the captains and crews of the R/V Connecticut for their outstanding logistical support for this field measurement program.
This dataset provides information for an oceanographic field study that occurred from January - May 2009 to investigate processes that control the sediment transport dynamics at Diamond Shoals, NC. Tripods were deployed at three sites along the outer perimeter of the shoal. Mounted on the tripods were instruments to measure surface waves, pressure, current velocity, bottom turbulence, suspended-sediment profiles, and sea-floor sand-ripple bedforms; one tripod also held a visual camera system. The measurements will be used to explore the oceanographic and sediment-transport processes responsible for maintaining the and distributing sand on the shoal. The background and experimental setup are described in the open file report "Carolinas Coastal Change Processes Project Data Report for Observations near Diamond Shoals, North Carolina, January-May 2009", on line at: https://pubs.usgs.gov/of/2011/1156/. The locations, deployment depths, sensor type and parameters measured during the deployment are presented in the table displayed by the Basic Sampling Interval link on the stellwagen server ( https://stellwagen.er.usgs.gov/diamondshoals-a.html ).
The North Site had three instrument deployments:
North Flobee at 35.17863N, 75.42292W at a water depth of 14.7 meters - instruments include Acoustic Doppler Current Profile (ADCP), Acoustic Doppler Velocimeters (ADVs), Optical Backscatter Sensors (OBSs), Acoustic Backscatter Sensor System (ABSS), Pulse-Coherent Acoustic Doppler Profiler (PCADP), Sontek hydra system, Seatech transmissometers, Paroscientific (Paros) Pressure Sensors, a Sea-Bird SEACAT, and a Sea-Bird MicroCAT.
North Minipod at 35.1783° N, 75.423355° W at a water depth of 14.8 meters - instruments include ADCP, time series visual image camera with flash, pencil beam and rotating sonar imaging system, Sea-Bird SEACAT, transmissometer, laser in-situ scattering and transmissometer instrument (LISST), and an Aquadopp Acoustic Profiler.
North Surface mooring at 35.177867N, 75.422617W at water surface - instruments include ARGOS (Seimac CML) and Iridium (Xeos melo) satellite beacons on the buoys to track position, a Sea-Bird SEACAT, a Sea-Bird MicroCAT and a pressure and temperature sensor (PT).
South Sites with two deployments:
South Flobee at 35.12958N, 75.49204W at water depth 14.0 meters - instruments include ADCP, ADVs, OBSs, an ABS system, a PCADP, Sontek hydra system, Seatech transmissometers, Paros pressure sensors, a Sea-Bird SEACAT, and a Sea-Bird MicroCAT.
South Surface Mooring at 35.12895N, 75.49187W at water surface - instruments include ARGOS (Seimac CML) and Iridium (Xeos melo) satellite beacons on the buoys to track position, a Sea-Bird SEACAT, and a PT.
Tip Site:
Tip Micropod at 35.098985N, 75.376055W at water depth 23.7 meters - instruments include upward looking ADCP, Sea-Bird SEACAT, and Seatech transmissometer.
The instruments were deployed and recovered aboard the R/V Connecticut, a research vessel owned and operated by the University of Connecticut. Ellyn Montgomery is the contact for this process step and the subsequent process step. Person who carried out this activity:
