This graphic is a summit ice core timeline depicting the phenomena that as we drill deeper ice cores, the ice gets older. The graphic compares this timeframe with major milestones in history. It is a concept developed by Zoe Courville and Dr. Mary Albert at Dartmouth University, in partnership with CRREL (Cold Regions Research and Engineering Laboratory).
The Transantarctic Mountains are an extreme example of rift flank uplift, extending over 3500 km across Antarctica and reaching elevations up to 4500 m (see map of the region). The mountain range was formed in the extensional environment associated with the breakup of Gondwanaland. Geological and geophysical work has shown that the Transantarctic Mountains developed along a long-lived lithospheric boundary
CTD Data plots from the Winter Sampling Expedition. CTD is an acronym for Conductivity-Temperature-Depth. It is a device that measures the salinity, temperature, depth in a vertical profile from the surface. The data comes from the Chukchi Sea.
