(1) Depth Charge

Hali Felt
This is the story about the pioneering woman scientist, Marie Tharp, who created the underwater topography map. In the 1940’s, things were more tough for a woman scientist!
Nature (Letters)
(2) Deglacial sea level rises caused by ice sheet saddle collapses
doi:10.1038/nature11257
Lauren, J. Gregorie, Antony, J. Payne & Paul, J. Valdes
*Melt water pulse 1A (MWP-1A) seemed to be caused by the separation of Laurentide and Cordilleran ice sheets around 14,000 years ago. Also, another 8,200 event could be from the separation of Labrador and Baffin ice dome.
Science (NewsFocus) Volume 337 (07/13/2012)
(3) Rising acidity brings an ocean of trouble
doi: 10.1126/science.337.6091.146
Robert, F. Service
*Ocean acidification caused the death of oyster larvae on the West coast of the U.S. This happened because the surface water was undersaturated for aragonite build up
Science (Reports)
(4) A reduced organic carbon component in Martian basalts
A. Steele et al.
doi: 10.1126/science.1220715
*11 Martian meteorites were analyzed to investigate the carbon cycles in Mars. This paper researched the origin of reduced carbon by the method called Raman Spectra. The samples seemed to be indigenous to Martian interior.
(5) Ice volume and sea level during last interglacial
A. Dutton and K. Lambeck.
doi: 0.1126/science.1205749
*Interglacial coral samples from 17 sites in the world were analyzed, and the authors concluded that the sea level was 5.5 to 9 m higher during last interglacial. This sea level rise seemed to be caused mainly by ice sheets melting, not radiation changes.
(6) Rapid progression of ocean acidification in the California current system.
Nicholas Gruber et al.
doi: 10.1126/science.1216773
* Eddy-resolving model revealed that California current systems are already low in carbornates, and by 2050 the saturation level of aragonite would drop to below 1 in most of the water.
PNAS Volume 109 (07/10/2012)
(7) Very high-temperature impact melt products as evidence for cosmic airbursts and impacts 12,900 years ago
Ted E. Buncha et al
doi: 10.1073/pnas.1204453109
*This paper confirmed the previous hypothesis: meteorite fragments deposited silica and iron rich macrospherules and caused Younger Dryas. The authors detected the evidences at 18 sites over 3 continents, and they were similar to the known cosmic impacts from 1945.
(8) Younger Dryas cooling and Greenland climate response to CO2
Zhengyu Liua et al.
doi:10.1073/pnas.1202183109
*The authors challenged the previous suggestion: Younger Dryas was as cool as Older Dryas. Their model showed Younger Dryas was 5℃ warmer than Older Dryas in response to CO2 rise.
