Harry Hess Postdoctoral Research Associate in Geosciences

The Department of Geosciences at Princeton University is accepting applications for a Postdoctoral Research Associate


Life below the seabed
The Scientist
Tiny fissures in 3.5-million-year-old rock hundreds of meters below the seabed are home to microbes that gain their energy from the rock itself, according to a paper published in Science. The study suggests that the largest ecosystem on the planet depends on energy, not from the sun, but from chemical reactions.

Karl K. Turekian 1927-2013
Karl Turekian, who was the Sterling Professor of Geology and Geophysics at Yale University, passed away March 15. Turekian was a world-renowned geochemist, past President of the Geochemical Society, editor or associate editor for eight geochemistry journals, author of numerous books and hundreds of papers. He received his A.B. from Wheaton College in 1949 and his Ph.D. from Columbia in 1955 then started what turned out to be a 50 year career as Professor at Yale. Turekian was a larger-than-life personality whose infectious enthusiasm for geochemistry contributed hugely to the development of the field. His personality shines through in his autobiography which chronicles his path through the wide range of geochemical topics to which he contributed over his remarkable career, and well displays his ability to tell a good story.

IEDA invites applications for Data Rescue Mini-Awards
IEDA Integrated Earth Data Applications (IEDA), the NSF data facility that operates EarthChem and the Marine Geoscience Data System, is accepting applications through April 5, 2013, for four Data Rescue Mini-awards. Applications selected by the program shall be awarded grants up to US $7,000 each as part of a Data Rescue Initiative. This initiative is intended to ensure that valuable legacy data sets that are in danger of being lost in the near future due to impending retirement or degradation of the original data source are preserved and made accessible to the community for re-use by inclusion in the IEDA data collections. Program details, as well as application instructions are available on the Mini-awards webpage.

10th Applied Isotope Geochemistry Conference
Abstract submission and early registration are now open for AIG10 to be held Sept. 22-27, 2013, in Budapest. The conference provides a forum where a wide range of applications of isotope analyses in geosciences and related fields are presented. The techniques cover the whole range of isotope analyses from light element stable isotope ratios to dating used in paleoclimate studies. AIG meetings are organized by the Applied Isotope Geochemistry Working Group of the International Association of GeoChemistry (IAGC).

Ozone layer above North Pole expected to recover by end of century
Good news for the ozone layer above the Arctic. The Montreal Protocol is showing effects: according to recent measurements, the ozone layer over the North Pole should recover by the end of the century. This is one of the main findings of the EU project RECONCILE, which was completed in February 2013.

Glaciers contribute significant iron to North Atlantic ocean
All living organisms rely on iron as an essential nutrient. In the ocean, iron's abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean's food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies a unexpectedly large source of iron to the North Atlantic — meltwater from glaciers and ice sheets, which may stimulate plankton growth during spring and summer.

Extreme water in Earth's interior
Earth is the only known planet that holds water in massive quantities and in all three of the main phase states. But the earthly, omnipresent compound water has very unusual properties that become particularly evident when subjected to high pressure and high temperatures.
