The ARSV Laurence M. Gould
is a major research platform for ocean and
climate studies. It is also the principal supply vessel for the U. S.
Antarctic Program research station at Palmer Station, Antarctica. It
routinely travels from Punta Arenas, Chile to the Antarctic Peninsula
region, crossing the Drake Passage 2 to 4 times per month. While the
ship is underway, one or more hull-mounted Acoustic Doppler Current
Profilers (ADCPs) measure the velocity of the upper-ocean currents below
the ship. The NB150 measures the upper 300 m of the water column with 8
m vertical resolution. The OS38, added in late 2004, increases the range
of current profiling to 1000 m depth, with a vertical resolution of 24 m.

a list of all cruises for that year, with links to
vector and contour plots.
The complete processed and edited data sets are archived
at the National Oceanographic Data Center (NODC) Joint Archive for Shipboard
ADCP (JASADCP).
The complete data set is easily located in the JASADCP inventory
under the ship name,
LM Gould,
or follow the individual links provided for each of the cruises listed by the appropriate year.

The collection, processing and dissemination of these data was carried out by the
Chereskin Lab at Scripps Institution of Oceanography, UCSD with support from the
National Science Foundation Office of Polar Programs grant nos. OPP-9816226,
ANT-0338103, ANT-0838750, PLR-1341431 and PLR-1542902. Eric Firing and Jules Hummon

provide critical support for the data acquisition and processing
of these ADCP data through the development and maintenance
of the UHDAS and CODAS software.
