Secret Ecosystem In Antarctica?

Secret Ecosystem In Antarctica?

Anyone know Dr. Ceridwen Fraser, the scientist who have discovered this, “secret ecosystem of plants and animals”?  Would be fascinating to hear more about her discoveries and research.

Researchers find secret, warm oasis beneath Antarctica’s ice that could be home to undiscovered species

Postdoc: NewZealand.MarinePhylogeography

Postdoctoral Fellow - Marine Phylogeography Department of Zoology Division of Sciences University of Otago NEW ZEALAND Applications are invited for the 3-year, fixed-term position of Postdoctoral Fellow at the University of Otago, New Zealand. We seek an energetic and dedicated scientist to carry out marine phylogeographic research. The successful candidate will be working on a Marsden-funded research project titled 'Founder Takes All? Tracking the colonisation of New Zealand's newly uplifted shores. The project is led by Professor Jon Waters, Associate Professor Ceridwen Fraser, Dr Erasmo Macaya, and Professor Dave Craw, The research will combine evolutionary genomic techniques with marine biogeography, in a geologically-active coastal setting. A PhD and research experience in evolutionary/population genetics/genomics is essential. Experience in marine phylogeography, GBS, and bioinformatics would be an advantage. The appointment is expected to start within the period March-May 2019.

The research reported today in Nature Climate Change by an international, multidisciplinary team of scientists including Professor Jon Waters from the University of Otago's Zoology Department and led by former PhD student Dr Ceridwen Fraser, shows kelp had drifted 20,000km to reach the Antarctica -- making it the longest known biological rafting event ever recorded.

To get there, the kelp -- which drifted all the way from the Kerguelen Islands in the Southern Indian Ocean -- had to pass through barriers created by polar winds and currents that were, until now, thought to be impenetrable.

DNA samples taken from the kelp revealed it had drifted from the Kerguelen Islands and another specimen from South Georgia. This meant the routes they took to reach Antarctica must have been tens of thousands of kilometres long.

"This study shows that Antarctica is not as biologically isolated as previously thought -- by demonstrating that rafting biological material can cross Southern Ocean barriers to reach the shores of Antarctica," Professor Waters explains.

The research changes the way scientists think about Southern Ocean oceanography, where storms can play a big role moving drifting material. The findings have important implications for the science of ocean drift that is used to track plastics, aeroplane crash debris and other floating material across our seas.
