Helen Fricker Associate Research Geophysicist at the University of California Helen Amanda Fricker is an Associate Research Geophysicist in the Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography at the University of California, San Diego. Helen received her B.Sc. in mathematics and physics from University College London (UCL) in 1991. It was at UCL that her interest in Antarctica began when she undertook a research project at the Mullard Space Science Laboratory, tracking icebergs in the Southern Ocean using satellite imagery. Helen was awarded her PhD from the Institute of Antarctic and Southern Ocean Studies, University of Tasmania, Australia in 1998. Her research focuses mainly on the marine cryosphere, in particular the floating portions of the Antarctic ice sheet (ice shelves). She uses a combination of satellite radar and laser altimetry, and other remote sensing data, to study the ice shelves. More recently she has applied the same data over the grounded ice sheet to reveal - in a scientific breakthrough that made headlines around the world - a subglacial water system under the west Antarctic ice streams. Helen also studies the propagation and evolution of active ice shelf rifts, which eventually lead to iceberg calving, using fieldwork and satellite remote sensing.
