ANTARCTICA - The only shipboard analysis we are doing for the JPCs on this particular cruise is for magnetic susceptibility (MS). MS gives us clues as to the geologic provenance of the sediments and entrained coarse material, which serves as a proxy for the depositional environment: a high MS indicates the presence of terrigenous material likely to have fallen out of the bottom of a glacier, whereas a low MS indicates a more open-water depositional environment and the absence of an overlying glacier. By running MS on the JPC and JGCs (and JTC, the trigger core), we can see what sediment we collected and start to loosely define different sedimentary and climatic events.

ST. PETERSBURG, FL - Congratulations to Tasha Snow on receiving a 2014 Antarctic Science Bursary award for her East Antarctic margin PhD research. The award is £4800, which in real money terms (and a weak US $) is $8140.
Here is more information on the program, which is run by Antarctic Science (a Cambridge University journal) and the British Antarctic Survey.
