Znanstvena
istraživanja na Antarktici
Najhladniji,
najnepristupačniji, najsuhlji, najnenaseljeniji, najzagonetniji, najčišći,
najekološkiji, najmirotvorniji, naj, naj, naj,.. najznanstveniji, kontinent.
Antarktika.
Na Antarktici godišnje boravi i radi oko četiri tisuće
znanstvenika različitih znanstvenih profila iz cijeloga svijeta. Proučavanjem
ovog jedinstvenog i najosjetljivijeg ekosistema na Zemlji, pokušavaju
pronaći odgovore i “ključ” za razumijevanje prošlih, sadašnjih i budućih
promjena na našem planetu.

South Pole Gets Colder
The South
Pole has been experiencing the coldest weather since record-keeping began
40 years ago. The National Science foundation which administers research
at Amundsen-Scott South Pole Station, said the average South Pole temperature
during July was minus 86.8 degrees Fahrenheit, breaking the previous record
of minus 83. degrees in July 1965. The coldest daily ttemperature recorded
in the month on July 29, was a minus 108.2.
July is the Southern Hemisphere`s coldest month. But cold
as it is, the South Pole Station has never reached the bitter extremes
recorded at Russia`s Vostok Station on Antarctica`s polar plateu. The
Guinness Book of World records says the world`s coldest temperature was
recorded at Vostok Statio on July 21, 1983: minus 128.6 degrees Fahrenheit.
During the current winter season, 28 men and women are
living at the South Pole. The Pole residents, scientists and technicians,
often observe an annual ceremony entitling them to membership in the “300
Club”. On the first day the outside temperature drops to minus 100 degrees,
initiates briefly roast themselves at 200 degrees Fahrenheit in the station
sauna before rushing naked outside their headquarters building, thereby
experiencing a drop in the temperature of 300 degrees.
The
Coldest Profession
Scientists
have found what appears to be the world`s southernmost red-light district.
Female penguins
on Ross Island (some 800 miles from the South Pole) are prostituting themselves
for small stones, which they use as building blocks for nesting platforms.
“What the
single male gets is copulation”, says Dr. Fiona Hunter of Cambridge University,
who`s observed the avian sex workers in action. “He may also get offspring”.
For the female, there is a reward for a job well done. Satisfied customers
sometimes tip with a second round of stones.

O
autoru
Tko
je Davorin Medaković?
Davorin Medaković, biolog i oceanolog, znanstveni
je suradnik u Zavodu za istraživanje mora Rovinj Instituta Ruđer
Bošković, Zagreb. Bavi se istraživanjima procesa biomineralizacije,
te utjecajem ekoloških uvjeta na promjene procesa biomineralizacije
i kalcifikacije različitih morskih organizama (vapnenih alga,
školjkaša, puževa, rakova vitičara i riba), proučavanjem podmorja
Antarktika, te zaštitom okoliša. Sudjelovao je u mnogobrojnim
ekspedicijama istraživanja podmorja Jadrana, Karipskog mora, Kanara,
Cipra i Antarktike. Autor je tridesetak znantsvenih radova.
