In cold pursuit / Sarah Andrews.

Enhanced descriptions from Syndetics:

Sarah Andrews is well known for her popular mystery series featuring forensic geologist Em Hansen. With In Cold Pursuit, she builds on that foundation and introduces a new lead character in this compelling mystery from the last continent.  Valena Walker is a dedicated master's student in geology headed to Antarctica to study glaciology with the venerable Dr. Emmett Vanderzee. Being on the ice is something she's dreamed about since she was a little girl. But when she finally arrives at McMurdo, she discovers that her professor has been arrested for murder, and what's more, that the incident happened a year ago. A newspaper reporter who'd visited Antarctica the previous winter had died from exposure, and though no one was a fanof the guy - he was attempting to contradict Vanderzee's research - by all accounts, everyone was devastated to lose someone on the ice.   Valena quickly realizes that in order to avoid being shipped north immediately and having her grant canceled, she must embrace the role of detective and work to clear his name - and save herself in the process.   Sarah Andrews received a prestigious grant from the National Science Foundation to spend two months on Antarctica to research In Cold Pursuit, and the authenticity of her portrait of this unforgiving land is breathtaking, making for her most compelling novel to date.
