Putting the brakes on runaway ice sheet retreat in antarctica christina hulbe tedxscottbase
Christina Hulbe, an Antarctic researcher, as of 2016 serves as Professor and Dean of Surveying at the University of Otago in New Zealand. Hulbe was previously Chair of the Geology Department at Portland State University in Portland, Oregon. She leads the NZARI project to drill through the Ross Ice Shelf and is the namesake of the Hulbe glacier.

Interview with portland state university glaciologist christina hulbe
Early life and education
Hulbe grew up in Sacramento, California, spending a lot of time in the Sierra Nevada and the Warner Mountains to the north. Her father was a geologist and professor (at Sacramento City College and Sacramento State University). She completed a degree in geological engineering from the Montana College of Mineral Science and Technology. She completed her MSc in 1994 at Ohio State University followed in 1998 by a Geophysics PhD from the University of Chicago.
Career and impact
In 1998 she held a NRC Research Associateship, NASA Goddard Space Flight Center. From there she moved to Portland State University in Portland, Oregon.
Her work in the late 1990s constituted the first melding together of the types of ice-sheet thermomechanical models (simulating ice-stream dynamics embedded within the flow of the inland ice sheet that behaves according to a different set of dynamics). She contributed to the understanding of ice-shelf instability, with some of the first papers that identified surface meltwater as an agent in the break-up of Larsen B ice shelf (in 2002).
She has developed methods used to identify ice-shelf and ice-stream flow variability as observed by the geometry of flow streaks and other indicators, and this is one of the few ways in which the history of glacial flow over the “medium past” (the past between the reach of direct observation and the more distant reach of ice coring).
Hulbe’s work in the understanding of Heinrich Events of the North Atlantic was informed by her experience with Antarctic-based ice-shelf and ice-stream instability (and sedimentology), and this has led to a mechanism that is currently popular in understanding Heinrich Events (the idea of deeper waters warming and destabilizing an ice shelf in the Labrador Sea is her idea). Most recently, Hulbe is lead investigator in a New Zealand project seeking to drill through the Ross Ice Shelf which would be the first mid-shelf peneration since J9 in the late 1970s.
Hulbe has been heavily involved with the International Glaciological Society (IGS) and over-saw its transition from a mode of service to the community to an open access publishing provider.
Awards and honours
Hulbe was Vice President (2009 – 2012) of the International Glaciological Society as well as a Fulbright Senior Scholar (New Zealand, 2009). She was awarded the Portland State University College of Liberal Arts and Sciences, John Elliot Allen Outstanding Teaching Award in 2004 and 2007. She also chairs the University of Otago Equity Advisory Committee and has written a history of women in glaciology and has campaigned extensively against armed conflict.
A glacier on the Siple Coast is named after her.
