DGPS A DGPS system from the WHOI OBS group was used along with acoustic ranging to locate the 6 OBS on seafloor. Navigation (no data reported)
Ocean Bottom Seismometer 6 WHOI ARRA OBS deployed, and each instrument was configured with a 3-component Trillium Compact intermediate-period seismometer and Cox-Deaton-Webb Differential Pressure Gauge. Data from these sensors is recorded using a Quanterra® Q330 datalogger and Quanterra® Packet Baler 44. Timing is provided by a Symmetricom® chip-scale atomic clock. All channels were recorded at a sample rate of 50 Hz. Ocean Bottom Seismometer (no data reported)
