A number of drifters have been deployed in the Southern Ocean
since 1994.  Two types of drifters have been used: physical
drifters that measure the location and sea surface temperature,
and optical drifters that measure the same parameters as well as
downwelling irradiance at 490 nm just above the sea surface and
upwelling radiance at seven visible wavebands just below the sea
surface.

This set of documents describes the instrument characteristics,
deployments, data processing and data format.  Access to the data
is also provided.

This study is part of an ongoing research effort in the Southern
Ocean by the Oregon State University (O.S.U.) Remote Sensing
Ocean Optics (ORSOO) group.
