The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson,.odvTxt
attribute NC_GLOBAL acquisition_description String The status of drogue presence is indicated by timing the submergence of the
surface float. When the drogue is attached, its drag will cause the surface
sphere to submerge occasionally as a wave passes. If the drogue has been lost,
the surface sphere remains at the surface and is not buried by waves. When the
surface float submerges, contacts on top of the sphere are shorted out by the
seawater and the PTT controller starts counting the length of time (seconds)
the contacts are shorted. Every 30 minutes the accumulated submergence time is
scaled by 0.1 (for example, 1000 seconds is scaled to 100) and loaded into the
first byte of the data string and a new submergence time is started. Typical
submergence values are 10 to 100. Consistent submergence values of 0 indicate
the drogue has been lost. The maximum submergence value is 180 and indicates
the surface float is sinking, or heavily fouled.

Those drifters with identifications starting with a \"g\" were generally
deployed in US territorial waters and those with an \"n\" deployed in Canadian
waters by the Bedford Institute of Oceanography.

attribute NC_GLOBAL instruments_0_description String Drifter buoy to include the Beardsley Drifter. Generic drifter buoys may be surface or sub-surface buoys that move with the current. They have a variety of instruments attached, providing a platform that allows for the measurement of surface drifts, air pressure and other variables. The Beardsley Drifters are near-surface satellite-tracked drifters used for observations of circulation patterns. They are WOCE-style drifters featuring holey sock drogues. Each drifter has a small (~ 30 cm diameter) surface float with ARGOS transmitter and batteries tethered to a holey sock drogue centered at 15 m below the surface. The drogue, about 10 m tall and 1 m in diameter, is designed to "lock" itself to the water so that the surface float follows the mean water motion at 15 m depth with very little slippage even in high winds. Thus measuring the drifter's position as a function of time provides a Lagrangian measurement of the 15-m ocean current.

attribute NC_GLOBAL projects_0_acronym String GB
attribute NC_GLOBAL projects_0_description String The U.S. GLOBEC Georges Bank Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, Haddock, and two species of zooplankton (Calanus finmarchicus and Pseudocalanus) - in terms of their coupling to the physical environment and in terms of their predators and prey. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.
The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).
Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.
The U.S. GLOBEC Georges Bank Executive Committee (EXCO) provides program leadership and effective communication with the funding agencies.
