A Look Back
By Tommy Dickey UCSB
If I were to choose a single phrase to
characterize the first century of modern
oceanography, it would be a century of
under-sampling.

Recommends Creating Virtual Marine Technology
Centers
Link existing capabilities, researchers and
students. Scientists and engineers work
collaboratively to solve fundamental
oceanographic questions. Large numbers of
platforms and sensors coordinated for
interdisciplinary research. Individuals not
required to acquire and master increasingly
complex instrumentation. Incubators for
innovation and new technologies, multi-purpose
focus enhances education. Located at existing
universities, science centers, etc. Recommendatio
n 27-6 NOAA should establish 4-6 national
virtual marine technology centers at existing
institutions to provide coordinated access,
through electronic means, to cutting-edge,
large-scale research technologies.

Communication
Each glider is equipped with two bi-directional
communication links, located in the tail.
FREEWAVE A high frequency radio (RF)
communication link (Freewave Technologies) allows
for high speed, line of sight data transmission
and a repeater can be used to increase the
distances of communication IRIDIUM Satellite
telephone link (Iridium Satellite LLC) also
provides global communication coverage.
ARGOS ARGOS transmitter is also located in the
tail and broadcasts GPS coordinates to locate the
glider in case of an emergency.

LaTTE 2005 -Post Injection 2 Final shipboard
survey After luring the Cape Hatteras offshore.
The survey began on the Highway. We were near
the glider when it surfaced. We saw currents
ripping southward in a 10 m thick layer of
freshwater along the highway -- perhaps the most
significant freshwater transport we saw all
week. Perhaps the most perplexing to me
is the Highway and why there has been a lack of
a strong coastally trapped flow this week.
