Description

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

Laurence M. Gould The project PI ships all NOAA Sound Velocity Profiling (SVP) drifters directly to Punta Arenas. The drifters will be stored in the USAP warehouse in Punta Arenas and onloaded to the vessel as required.

After each deployment staff technicians will send an email to the PI indicating the buoy identification number, date and location (latitude/longitude) where it was dropped. This consists of a scanned copy of the log sheet with deployment notes supplied for the technicians by NOAA with each drifter buoy.

For all LMG cruises, one drifter will be deployed by staff technicians during each crossing of the Drake Passage (two per cruise, one southbound and one northbound). For optimal spacing, deployments will be staggered between the southbound and northbound voyages. For example, on the southbound leg a drifter will be deployed at 59?degrees south latitude; on the northbound leg a drifter will be deployed at 60 degrees south latitude. Cruises for deployment in 2017-18:

LMG17-09 LMG17-10 LMG17-11 LMG17-12 LMG18-01 LMG18-02 LMG18-03 LMG18-04 LMG18-05 LMG18-06 LMG18-07

Nathaniel B. Palmer The PI ships all NOAA Sound Velocity Profiling (SVP) drifters directly to Punta Arenas or the port of operation for the NBP. The drifters will be stored in the USAP warehouse in Punta Arenas and onloaded to the vessel for NBP18-01 and shipped directly to Hobart for onload on NBP18-02.

After each deployment staff technicians will send an email to the PI indicating the buoy identification number, date and location (latitude/longitude) where it was dropped. This consists of a scanned copy of the log sheet with deployment notes supplied for the technicians by NOAA with each drifter buoy.

The following cruises and number of deployments are as follows: NBP18-01A: 15-20 drifters, (ex: one deployed every 5 degrees of longitude (90W, 95W, 100W) or once per day)

NBP18-02: 15-20 drifters,

NBP18-06 (CRUISE PENDING)
