During the past decade, Antarctica's massive ice sheet lost twice the amount of ice in its western portion compared with what it accumulated in the east, according to Princeton University researchers (Prof. Frederik Simons and Res. Sch. Christopher Harig) who came to one overall conclusion — the southern continent's ice cap is melting ever faster.
If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links three out of four such days to man's effects on climate.
On two ~25 day long, trans-Atlantic cruises, the Ward Lab ventured to the subarctic ocean. In collaboration with the Sigman Lab, they studied the contribution of pico- to meso-sized plankton to the cycling of carbon and nitrogen. These late summer (2013) and spring (2014) subarctic North Atlantic cruises followed-up the cruises in the western subtropical gyre (Sargasso Sea) and provided the opportunity to compare the roles of plankton functional groups between two very different ocean biomes.
At issue is the use of airguns, the standard tool for studying the 70 percent of Earth below the seabed. Environmental groups claim the airguns will bring death and destruction to marine life. In making this claim, they ignore the fact that for some 40 years of using airguns, no significant impact on marine life has been demonstrated.
Observation and numerical climate model prediction do not always match when it comes to atmospheric temperature trends in Earth’s tropics. Some skeptics have focused on the mismatch, and the question of a systematic problem in the models has been raised. Recently, AOS researcher Thomas Flannaghan, The Fueglistaler Group, and AOS Prof. Issac Held (EtAl) set out to find the source of the problem.
In a recent investigation led by Dr. Maggie C.Y. Lau, scientists in the Department of Geosciences, Princeton University, McGill University and the University of Tennessee‐Knoxville have identified a surprising sink for atmospheric methane (CH4): the mineral soils of the Canadian high Arctic.
GEO grads Pathikrit Bhattacharya, Jaya Khanna, Jahnavi Punekar and the Association of South Asians at Princeton invite you to attend a unique classical dance and music festival in Princeton, NJ, featuring world renowned maestros.
Professor of Geosciences Jeroen Tromp and his team project SPECFEM is among the 13 partnership projects selected by the Oak Ridge Leadership Computing Facility (OLCF) to participate in the Center for Accelerated Application Readiness (CAAR) program. CAAR is a program in preparation for the next-generation supercomputer “Summit” that will power up and be released to the Department of Energy (DOE) research community in 2018.
If a picture is worth a thousands words, a computer graphic is worth millions. With that in mind, Princeton University has formed a consortium that will share efforts to turn mountains of scientific data into eye-friendly computer visualizations.
Bess B. Ward, the William J. Sinclair Professor of Geosciences and Chair of the Department of Geosciences, is pleased to announce Satish Myneni’s promotion to Professor of Geosciences.
