A chance meeting between a pair of treasure-hunting brothers and Tony Irving, an affiliate professor in the Department of Earth and Space Sciences, has led to the discovery of some the most extraordinary and valuable meteorites in history. Read more here.
The coldest deep ocean water that flows around Antarctica in the Southern Ocean has been mysteriously disappearing at a high rate over the last few decades, scientists have found. Sarah Purkey, graduate student in oceanography and lead author of the study, is quoted. Read more here.
Professor Norbert Untersteiner – Department of Atmospheric Sciences in UW’s College of the Environment – passed away earlier this month; he was 86. Read about his remarkable life and legacy – from his childhood in Austria to his adventures and work in the Arctic – in this Seattle Times piece.
Geologists in the Department of Earth and Space Sciences at the College of the Environment have discovered a new type of landform to which there are not many analogs here on Earth. To learn more, click here.
UC Santa Barbara resource economists Christopher Costello and Robert Deacon, and SAFS‘ Ray Hilborn and Trevor Branch will be undertaking an examination of the ongoing effects of a West Coast fisheries management system implemented by NOAA in January 2011. This effort is funded as part of a $1 million West Coast Sea Grant social science initiative, funded by NOAA Sea Grant and its partners. Read more about this effort here.
(Credit: NOAA) A layer of Antarctic Bottom Water colder than 0ºC (colors, with darkest blue areas having the thickest layer, and white none) covers the ocean floor around Antarctica (center, shaded grey). Rates at which this layer is thinning during the study period (red numbers in meters per decade) are shown for for each deep basin (outlined by thin grey lines). These rates are estimated using data from repeated oceanographic expeditions (ship tracks shown by thick black lines). Note that seawater at the ocean surface stays liquid even at temperatures approaching -2ºC because of its high salt content.
Oceanographers have found that Antarctic “Bottom Water”, the coldest deep ocean water, has been disappearing at an average rate of about 8 million metric tons per second over the past few decades. This new study suggests that significantly less of this bottom water has been formed during that time than in previous decades. The School of Oceanography‘s Sarah Purkey and Gregory Johnson are co-authors of this study. Read more here!
A new online portal and iOS app, announced just a little over a year from the devastating tsunami in Tohoku, Japan, will help Oregon and Washington residents figure out whether they are in harm’s way should a tsunami hit. People can enter addresses and store and share evacuation routes for multiple locations. Oceanography’s Jan Newton is a key member of this project. Read more here!
