A new model, developed by a Victoria University of Wellington Ph.D. student, could help to more accurately predict how Antarctica's ice sheets will respond to a warming world and impact global sea level rise.

Dan Lowry, from the University's Antarctic Research Centre, developed the model and has just published an article about it in the well-respected science journal Science Advances.

Article - Deglacial - Line - Retreat - Ross

The article is titled Deglacial grounding line retreat in the Ross Embayment Antarctica, controlled by ocean and atmosphere forcing.

Dan says the purpose of his research is to determine how stable the West Antarctic Ice Sheet is in a warming world to help project future sea level rise.

Findings - Controls - Retreat - Place - Ross

"Our main findings are that ocean and atmosphere warming are the primary controls on the major glacial retreat that took place in the Ross Embayment since the last ice age.

"But significantly, our modeling showed that the dominance of these two controls in influencing the ice sheet was different at different times, with melting from underneath the Ross Ice Shelf due to ocean warming becoming the main driver of ice sheet retreat over time," he says.
