Prominent Scientist Gordon Hamilton Dies in Antarctica

Gordon Hamilton, a respected glaciologist, died recently while on field research in Antarctica after his snowmobile fell 100 feet into a crevasse. The 50-year-old associate research professor worked at the University of Maine where he studied the effects of climate change on the shrinking glaciers of Greenland and Antarctica.

Dr. Hamilton had been conducting field research about 25 miles south of McMurdo Station, the largest of three U.S. research stations in Antarctica, located on the southern tip of Ross Island. He was driving his snowmobile in a remote area known as the McMurdo shear zone where two large ice shelves meet and crevasses are typically found.

Leigh Stearns, Assistant Professor at the University of Kansas, who worked with Gordon Hamilton for over 17 years, including for 24 months of fieldwork, talked to GlacierHub about the risks facing researchers like Hamilton: “There are certainly dangers associated with doing fieldwork in remote places,” she said. “However, we spend so much time and effort thinking about these risks and trying to mitigate against them, that I think we’re often safer in the field than at home.”

According to Stearns, Gordon was experienced and extremely cautious doing fieldwork. “This trip to Antarctica was no exception. It should be noted that there is nothing anyone could have done to prevent the accident that killed him.”

Jonathan Kingslake, a glaciologist at Columbia University, agreed: “I am keen to point out that the risks are not that great and accidents are actually quite rare.”

According to Kingslake, many observations vital for understanding ice sheets can only be made by moving around on the surface of the ice, even despite advances in satellite and airborne remote sensing.

“Ground-based polar fieldwork involves different risks than you face in normal life,” he said. “For example, extreme cold, light aircraft use, and crevassing. These can be exacerbated by remoteness, but usually the risks can be mitigated successfully. Only rarely do serious accidents happen.”

Dr. Hamilton set fear aside in Greenland and Antarctica frequently, including during a decades-long stretch when he went to Greenland two to three times a year for field work. He supplemented his research by using satellite remote sensing to track the shrinking of the ice sheets in both Greenland and Antarctica. 

According to an interview Hamilton gave last year, “No research had previously been conducted on the oceanic waters of a typical fjord” in Greenland. By going out into the field, despite known dangers, Dr. Hamilton discovered that water temperatures reached 4°C between 200 meters and 1000 meters below the surface, within 20 km of the edge of the ice sheet. Hamilton believed this was the best explanation for the abrupt changes observed in Greenland over the past 15 years. “They’ve all been caused by the ocean,” he said at the time. Although he knew the risks, as all glaciologists do, Hamilton lived his life with courage, in pursuit of a greater truth about our changing climate.

The death of Hamilton in Antarctica has since sent shock waves through the research community. On behalf of the National Science Foundation’s Division of Polar Programs, Dr. Kelly K. Falkner released a statement about the community’s tragic loss. The statement reads: “The U.S. Antarctic Program is a close-knit corps of researchers and support personnel who carry out the nation’s program of research in Antarctica, working at the frontiers of human knowledge, but also at the physical frontiers of human experience. The death of one of our colleagues is a tragic reminder of the risks we all face—no matter how hard we work at mitigating those risks—in field research.”

Dr. Stearns added her own thoughts about her research partner: “He was a fantastic mentor, colleague and friend. He was incredibly generous with his time and ideas and had great humility and humor.”

Dr. Hamilton earned a Bachelor Science at the University of Aberdeen in geography in 1988 and a Ph.D from the University of Cambridge in geophysics in 1992. He also worked at the Norwegian Polar Institute and at the Byrd Polar Research Center, joining the University of Maine in 2000. His research interests included outlet glacier dynamics and kinematics, icebergs, ice-ocean interaction in Greenland, and ice shelf stability in Antarctica.

Although his death was unexpected, one thing remains certain: Hamilton died doing work that he loved. “I love my job,”  Hamilton said in 2013 in a video for the Climate Change Institute. “I can’t think of a better job or another job that I would rather be doing. As a scientist, it is incredibly exciting to be in a field that is evolving so rapidly.”

Prominent Climate Scientist Dies in Antarctica

New York Times: “Gordon Hamilton, a prominent climate scientist who studied glaciers and their impact on sea levels in a warming climate, died in Antarctica when the snowmobile he was riding plunged into a 100-foot-deep crevasse. He was an associate research professor in the glaciology group at the Climate Change Institute at the University of Maine. He was camping with his research team on what is known as the Shear Zone, where two ice shelves meet in an expanse three miles wide and 125 miles long. Parts of the Shear Zone can be up to 650 feet thick and ‘intensely crevassed.’ Dr. Hamilton’s research, aided by a pair of robots equipped with ground-penetrating radar instruments, focused on the impact of a warming climate on sea levels. He was working with an operations team to identify crevasses.”

Antimony Found in the Tibetan Glacial Snow

Journal of Asian Earth Sciences: “Antimony (Sb) is a ubiquitous element in the environment that is potentially toxic at very low concentrations. In this study, surface snow/ice and snowpit samples were collected from four glaciers in the southeastern Tibetan Plateau in June 2015… The average Sb concentration in the study area was comparable to that recorded in a Mt. Everest ice core and higher than that in Arctic and Antarctic snow/ice but much lower than that in Tien Shan and Alps ice cores… Backward trajectories revealed that the air mass arriving at the southeastern Tibetan Plateau mostly originated from the Bay of Bengal and the South Asia in June. Thus, pollutants from the South Asia could play an important role in Sb deposition in the studied region. The released Sb from glacier meltwater in the Tibetan Plateau and surrounding areas might pose a risk to the livelihoods and well-being of those in downstream regions.”

Managing Glacier Related Risks Disaster in Peru

The Climate Change Adaption Strategies: A recently edited book, “The Climate Change Adaptation Strategies – An Upstream – Downstream Perspective,” edited by Nadine Salzmann et al., has several chapters on glaciers. The chapter “Managing Glacier Related Risks Disaster in the Chucchún Catchment, Cordillera Blanca, Peru” discusses some of these glacier related risks: “Glacial lakes hazards have been a constant factor in the population of the Cordillera Blanca due their potential to generate glacial lake outburst floods (GLOF) caused by climate change. In response, the Glaciares Project has been carried out to implement three strategies to reduce risks in the Chucchún catchment through: (1) Knowledge generation, (2) building technical and institutional capacities, and (3) the institutionalization of risk management. As a result, both the authorities and the population have improved their resilience to respond to the occurrence of GLOF.”
