    String acquisition_description 
"During the July-September 2001 Southern Globec cruises of the Palmer and Gould
we installed four buoys. Two of the buoys (07413, 07440) were standard off-
the-shelf Met-Ocean Ice buoys (see above photograph). These buoys measured
barometric pressure, air temperature, and GPS position. The data were
transmitted via ARGOS. A radar reflector was mounted on a wooden 4 x 4 to help
find the site if there was an opportunity to return, however the reflector
return was difficult to discern among all the backscatter clutter caused by
deformed ice and icebergs.
The other two buoys (07949, 07950) were custom made CRREL ice mass balance
buoys (photo on right). These buoys reported barometric pressure, Argos
position, and air temperature. In addition they had a thermistor string that
measured a vertical profile of temperature, at 10 cm spacing, from the air,
through the snow and ice, and into the upper ocean. There were acoustic
sensors measuring the positions of the snow surface and ice bottom. A
fluorometer was mounted under the ice. One of the buoys (07949) had three
spectroradiometers; one mounted about the ice, one mounted directly below the
ice, and one a few meters deep in the upper ocean. Results from all buoys are

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.

Research in the Southern Ocean (SO) indicates strong coupling between climatic processes and ecosystem dynamics via the annual formation and destruction of sea ice. The Southern Ocean GLOBEC Program (SO GLOBEC) will investigate the dynamic relationship between physical processes and ecosystem responses through identification of critical parameters that affect the distribution, abundance and population dynamics of target species. The overall goals of the SO GLOBEC program are to elucidate shelf circulation processes and their effect on sea ice formation and krill distribution, and to examine the factors which govern krill survivorship and availability to higher trophic levels, including penguins, seals and whales. The focus of the U.S. contribution to the international SO GLOBEC program will be on winter processes. This component will focus on the distribution and activities of sea ice microbial communities. This will be accomplished using an integrated combination of sampling (vertical profiles, horizontal surveys, and under-ice surveys) and observational protocols. Experiments will be designed to estimate microbial activity within the sea ice and at the ice-seawater interface. The research will be coordinated with components studying the water column productivity and the sea ice habitat. The result of the integrated SO GLOBEC program will be to improve the predictability of living marine resources, especially with respect to local and global climatic shifts.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
For example,
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
