Shipboard ADCP website
Laurence M. Gould
The US National Science Foundation (NSF) Office of Polar Programs (OPP) funds the operation of two Research Vessel Ice Breakers (RVIB) in the Antarctic: the Nathaniel B. Palmer and the Laurence M. Gould. Both ships now have dual frequency shipboard ADCP systems based on RD Instruments narrowband VM-150 and Ocean Surveyor phased array 38 kHz profilers, with precision (PPS, or P/Y-code) GPS navigation and with heading corrections provided by GPS attitude sensors (Ashtech, Seapath). These systems offer the prospect of routine current profile measurements in the upper 1000 m along a variety of cruise tracks through otherwise rarely sampled waters of the Southern Ocean.
Dr. Teresa Chereskin at Scripps Institution of Oceanography and Dr. Eric Firing and Dr. Jules Hummon at University of Hawaii are funded by the NSF OPP to oversee the operation of these ADCP systems. This link displays the shipboard ADCP website on the ARSV Laurence M. Gould that provides documentation, plots, and data. At sea, the plots and data are updated hourly throughout the cruise. From this link you are seeing plots based on LMG archived data from our shore-based mirror site maintained at University of Hawaii.
