We prepare and analyze foraminiferal samples for faunal composition, stable isotopes, and radiocarbon dating.  Equipment includes sieves, binocular microscopes, identification books, a reference slide collection, and more. Our data help reconstruct past marine and glacio-marine environments.

Example project - Studying past climates and ice shelf history of Petermann Glacier and Nares Strait, northwestern Greenland

In the summer of 2015, we spent a month aboard the Swedish icebreaker ship Oden to collect marine sediment cores from Petermann Fjord and northern Nares Strait, a gateway between the Arctic and Atlantic oceans. We processed the cores in a lab on board ship to start reading the history of past climates and ice shelves.  Intensive followup work by ourselves and colleagues took place over subsequent years in multiple labs, including the INSTAAR Micropaleontology Lab.

Video
See Anne Jennings on 60 Minutes in the 2016 video below.  She talks about forams and sediments that hold clues to Petermann Glacier's past.  The video discusses both land and marine research.  The marine section starts at the 7-minute mark; Anne appears at the 9.5-minute mark.
