Argentine is one of the original treaty signatories and had been closely involved into an international level of cooperation. As a matter of fact there are joint projects that are implemented on a regular basis with other countries.

spirit of international collaboration started with the
logistical support to the Dr. Otto Nordenskjöld´s
expedition to the Antarctica and his rescue for the
corvette Uruguay under the command of the Liutenant
Julián Irizar in 1903.
February 22, 1904 a meteorological station in the Laurie
Island (South Orkney Islands) has been operated
continuously for the argentinean government.
present there are six permanent scientific stations in
the Argentine Antarctic Sector : Orcadas, Marambio,
Jubany, Esperanza, San Martín and Belgrano II. The
principal scientist investigations involve biology,
geology, glaciology, geophysics, meteorology,
vulcanology, upper atmospherics, human biology and
medicine, environmental, fisheries, and global change
other hand are seven only-summer scientific stations :
Brown, Matienzo, Primavera, Cámara, Melchior, Petrel and
Decepción. These instalations brings the necesary
infractructure to support specific science programs in
the summer, like studies on biotic communities,
systematic collection of data and samples and
conservation of the historic monuments. In the Antarctic,
people are needed to provide shipping and air services,
to build and mantain scientific stations, to look after
the health of expeditioners, and to help researchers in
Antarctic program is logistically supported by the
icebreaker Almirante Irizar using helicopters and
watercrafts to move personnel and cargo from ship-to-shore
and in the other hand include improving infractructure
to support scientific research, environmental protection,
and waste managment more effectively.
1979 this ship has served every year in the antarctic
continent not only suppliying scientific research
stations but also working as a floating laboratory or
carrying out search and rescue.
has laboratories and has berthing to accommodate
scientists, the cranes and work areas give the
scientists the capability to do at-sea studies of
geology, oceanography, sea-ice physics, and other
several disciplines. At the present time is the only
icebreaker in all the South Hemisphere.
cojunction with the argentinean station Jubany on King
George Island ( Antarctic Peninsula, South Shetland
Islands ) the Alfred Wegener Intitute operates The
Dallmann Laboratoty, together with Argentina and The
Netherlands. In January 1994 the Alfred Wegener
Institute and the Instituto Antártico Argentino jointly
opened the Dallmann Laboratory and this is the first
reseach facility in the Antarctic for wich an
international agreement was concluded for colaboration
between reseachers from Germany, The Netherlands and
Argentina. The Dallmann Laboratory can accomaodate
twelve scientists, it offers living and working space,
and is equipped with four laboratories, storage space,
an aquarium container, diving equipment and some igloo
huts. Although the Jubany station develops her
activities throughout the year, the Dallmann Laboratory
is only open during the summmer months between October
and March. There are few Antarctic areas where the
coastline is not covered by thick shelf ice and this is
the most important quality avaible at Jubany station.
Reseach divers investigate the composition and stability
of algal and faunal communities.
from Argentina, The Netherlands and Germany are jointly
involved in most of the projects. However, the
laboratory is also opened to reseachers from other
The passenger’s ship "CLIPPER ADVENTURER"
been freed from the pack-ice by the Argentine Icebreaker
A.R.A "Almirante Irizar".
January 31, 2000, while the Icebreaker ARA "Almirante
Irizar" (RHAI) was performing repairs on beacons an some
oceanography tasks, on the Bismark narrows at 07:55
local time, a call was received from the Passenger Ship
"Clipper Adventurer" (CA) on position Lat 66º43´S Long
67º31´W asking for the assistance of an icebreaker
because it was trapped by the pack-ice. The distance
from the ship to clear waters was 28 km and the
passenger ship could not sail them. The wind and the
tide on this zone made the ice press the hull of the
ship more as the time was passing.
Clipper Adventurer was north of Belgrano Island, with 70
passengers and 115 crew members. It has 300 feet overall
length and is not prepared to navigate on conditions
with packed ice. She was more than 400 km from the
Almirante Irizar's position.
given by Irizar's Captain was to navigate at maximum
speed possible and to get ready the different rescue
systems for the tow at the same time.
hrs the icebreaker arrived at the Matha narrows. Our
helicopter made a flight to overview the situation,
which was defined as complex. It was going to take
several hours of continuous work to free the Clipper
Adventurer from the pack-ice. The density of the field
was 10 tenths and made the maneuver a difficult one.
minutes before midnight, the Almirante Irizar reached
the ice near the Clipper Adventurer. The intention was
to release the pressure of the ice on the hull of the
ship and create a channel in order to have some free
waters for the return trip. At the same time we had to
turn the ship since it was pointing south and the exit
was on the north. We made several maneuvers close to the
ship, sometimes close to 10 meters.
hrs the first tow line was passed between the bow of the
CA and the stern of the RHAI, turning it 30º to
starboard to drive it inside the channel opened by the
hrs, after turning the ship, we started the tow through
the opened channel.
hrs we had to let go the tow line in order to open a new
channel because the first one was closed and had changed
hrs we passed the tow line again and towed the Clipper
Adventurer to open waters.
minutes later, at 09:10 hrs we finally left the icefield,
and the Icebreaker Almirante Irizar escorts the Clipper
Adventurer until her Captain confirms no damage was
caused and she could sail in perfect conditions.
Breaking the ice
concepts about the technics employed for the icebreakers.
an icebreaker, like the Almirante Irizar, is capable of
breaking very thick ice it takes longer and consumes
more combustible therefore if possible the ship will
avoid the ice.The most efficient form to break through
ice is to find the weakest points and break through
where less force will be required.
normally done by exploting open areas when there are
none, the ship is piloted , when it is possible, over
the first year ice due to one important fact:as sea ice
gets older it becames stronger.
kind of ice is multiple year ice, it has a vissible
quality, a deeper blue color and its hardness is even
more distinctive, and causes the icebreaker to slam and
ship has to back and ram, to proceed forward through
this type of ice.
the pack stop the vessel, it willl back down between one
half and two ship lenghts though the track cut at her
stern, so the icebreaker uses its engines to create as
much forward momentum as possible.The momentum of the
ship ( the product between her displacement and her
speed) will carry it up higher on the ice, and push it
ahead with more force to breaf through, the ice is
pushed down by the weight of the ship wich causes the
ice to break off in chunks.The broken ice is then pushed
out of the way by the hull of the icebreaker as it
other hand this process consumes much greater amounts of
fuel and time. The hull is designed to absorb high-powered
rams into ice.The form of the bow allows the icebreaker
to firts ride up on top of the ice, then the bow is
levered down by gravity through the ice and causes his
