Recently AGES lab members Sidney Hemming and Trevor Williams sailed on International Ocean Discovery Program Expedition 382, to collect long sedimentary records of sources of iceberg rafted sediments around Antarctica and evidence for past history of Antarctica's ice sheets and ocean circulation (https://iodp.tamu.edu/scienceops/expeditions/iceberg_alley_paleoceanography.html ). 

The Paradox Basin is a Paleozoic Basin in the Southwestern United States that holds geologic, hydrologic, and economic importance. As such, it is desirable to understand the history of the Paradox Basin in terms of geologic forcings, hydraulic fluxes, and fluid-flow reactions. Prior work measured (U-Th)/He ages on the abundant Fe- and Mn- oxides found throughout the basin. However, as a ligheight noble gas that is known to leak out of mineral structures at low temperatures, these helium ages frequently record cooling ages rather than actual formation ages.
