2020-2021 USAP Field Season
NOAA’s Global Drifter Program (GDP)
Dr. Shaun R Dolk
Supporting Stations: ARSV Laurence M. Gould, RV/IB Nathaniel B. Palmer
The Global Drifter Program (GDP) is the principal component of the Global Surface Drifting Buoy Array, a branch of NOAA's Global Ocean Observing System (GOOS) and a scientific project of the Data Buoy Cooperation Panel (DBCP). Its objectives are: (1) to maintain a global 5x5 degree array of 1,250 ARGOS-tracked surface drifting buoys to meet the need for an accurate and globally dense set of in-situ observations of mixed-layer currents, sea-surface temperature, atmospheric pressure, winds, and salinity; and (2) to provide a data processing system for scientific use of these data. These data support short-term climate predictions as well as climate research and monitoring.
Field Season Overview
For ARSV Laurence M. Gould (LMG) cruises, one drifter will be deployed by ASC technicians during each crossing of the Drake Passage (one southbound and one northbound). ASC technicians will also deploy drifting buoys while underway onboard the RV/IB Nathaniel B. Palmer (NBP) during various cruises throughout the year.
