Description

Initial positions of drifters deployed from 1995 to 1999 in support of the U.S. GLOBEC Georges Bank program. For drifter tracking, see the 'drifter_tracks' dataset.

Notes:
¹Drifters named with a leading 'g' were generally deployed in US terriorial waters and drifters identified with a leading 'n' were deployed in Canadian Waters by Peter Smith from the Bedford Institute of Oceanography (BIO). Also, drifter types containing a gps system reported positions every 30 minutes.

²'inst' parameter is a combination of: Manufacturer code (se = Seimac, cw = Clearwater, met = MEtocean, to = Technocean) + Center depth of drogue (10 or 40 meters) + Shape of drogue (W = wide, versus a square drogue) + Presence of gps system (gps)

Methods & Sampling

Satellite-tracked drifters with holey sock drogues centered at 10, 15 and 40-m depths were deployed over Georges Bank during 1995-99 in support of the U.S. GLOBEC/Georges Bank Program. Some drifters were deployed in regions of strong vertical shear over the Bank and these drifters had a drogue that was twice as wide and half as long as the standard drogue and are designated as having ‘wide’ drogues (see note 2 above). Drifter types containing a gps system reported positions every 30 minutes.

Data Processing Description

BCO-DMO corrected unknown/missing cruise ID's for the following drifters:
g31- corrected to EN274. (Cruise report for EN274 documents the deployment of g31.)
g47- corrected to EN278. (Original data has EN278 listed.)
g84 and g85 - corrected to EN291. (EN291 cruise report documents the deployment of these drifters.)
g98 and g99 - corrected to EN294. (EN294 cruise report documents the deployment of these drifters.)
g140 and g142 - corrected to EN300. (EN300 cruise report documents the deployment of these drifters.)
g157 and g158 - corrected to OC315. (Original data has OC315 listed and Oceanus schedule confirms dates, locations, and investigators.)
g159 - corrected to OC316. (Original data has OC316 listed and cruise report confirms this.)
n6 to n10 - corrected to PAR98-078. (Cruise report for PAR-98-078 documents the deployment of these drifters.)

Instruments

Drifter Buoy

Supplied Description:

Satellite-tracked drifters with holey sock drogues centered at 10, 15 and 40-m depths were deployed over Georges Bank during 1995-99. The GLOBEC Georges Bank drifters were made by Clearwater (CW), Seimac (SE), Technocean (TE), and MEtocean (ME).

Instrument Type

Generic Name: Drifter Buoy

Generic Description:

Drifting buoys are free drifting platforms with a float or buoy that keep the drifter at the surface and underwater sails or socks that catch the current. These instruments sit at the surface of the ocean and are transported via near-surface ocean currents. They are not fixed to the ocean bottom, therefore they "drift" with the currents. For this reason, these instruments are referred to as drifters, or drifting buoys.

The surface float contains sensors that measure different parameters, such as sea surface temperature, barometric pressure, salinity, wave height, etc. Data collected from these sensors are transmitted to satellites passing overhead, which are then relayed to land-based data centers.
