INPE Launches Meteo-Oceanographic buoy in Antarctica
Hello
reader!
It
follows a note published on the day (11/06) in the website of the National
Institute for Space Research (INPE) informing that the
institute launches Meteo-Oceanographic Buoy in Antarctica.

INPE Launches Meteo-Oceanographic
Buoy in
Antarctica
Tuesday, November 06, 2012
Studies on the
interactions between the ocean, the coastal zone and the atmosphere in the
region of Deception Island, Antarctica, will benefit from the data collected by
new equipment of the National Institute for Space Research (Instituto Nacional
de Pesquisas Espaciais - INPE). Under the project INTERCEPTION, launch and
docking of a large meteo-oceanographic buoy have been performed between
November 1 and 3, during the 31st Antarctica Operation of PROANTAR.
The buoy
weighs about 700 kg and has 2 meters in diameter, housing a lot of
oceanographic and meteorological sensors and one platform (PCD-ARGOS) that
enables the receipt of measured data in real time.
Meteorologists
Marcelo Santini and Rose Freitas, of the Southern Regional Center of INPE
(CRS/INPE), have coordinated the launch in the bay of Port Foster, Deception
Island, formed by an active volcano whose summit juts out of the water above
sea level - the horseshoe shape allows entry of vessels in the area of
destroyed volcano crater. The geotectonic ambiance affects the characteristic
of water masses and oceanic circulation within Port Foster, which causes impacts
on the surrounding atmosphere in the form of turbulent flows and in the coastal
zone by means of changes in currents systems, waves and tides.
"The
strong warming of coastal waters in Southern Ocean at the bay of the island
locally regulates the heat flows in the interface with atmosphere, in the open
ocean and in the coastal area adjacent to the island," says Ronald Buss,
researcher for CRS/INPE in Santa Maria (RS) who heads the INTERCEPTION
(Ocean-Atmosphere-Coast Micro Scale Interactions in Deception Island,
Antarctica) project of CNPq/PROANTAR motivated by the lack of
meteo-oceanographic data in the region.
Brazilian
Industry
The project
has a lot of national instrumentation. "The system was fully built and
assembled by a Brazilian company. Thus, INPE reaches two important goals of its
performance: advancement of scientific knowledge and its applications and
advancement of national industry qualification for design and manufacturing of
technological products," said Leonel Perondi, director of INPE.
The
meteo-oceanographic buoy that will be used in the automatic collection of data
on the atmosphere and the ocean over the years in shallow sea (20m deep) of
Port Foster bay was produced by NEURON, a partner company of INPE in
oceanographic instrumentation projects.
Unprecedented
This was the first time in PROANTAR history that this
type of instrument was launched into polar waters by a Brazilian ship - the
Almirante Maximiano of Brazil’s Navy. During their stay at Deception Island and
nearby, two Acoustic Doppler Profilers (ADPs) were also anchored for monitoring
ocean currents next the meteo-oceanographic buoy. Launches of atmospheric
radiosondes and oceanic probes XBTs (Expandable Bathy-Thermographs) were also
performed.
The INTERCEPTION team will return to Brazil on Nov. 9 by
Brazilian Air Force plane from the Chilean Base Eduardo Frei, King George
Island, Antarctica.
