The world’s glaciers, many of which have been around for millions of years, are in danger. Glaciers today are retreating faster than ever recorded. Some glaciers in tropical regions are on the verge of disappearing in the coming decades. Climate scientists and glaciologists are on the frontlines of understanding how climate change is threatings iconic glaciers, impacting tourism, ecosystems, and communities dependant on glaciers for water.
The Journal of Glaciology has recently brought on several new science editors. Although the journal is now over 70 years old, it’s gained importance and readership over the years as awareness of climate change has grown. The journal and its editors cover mostly the natural sciences such as chemistry, biology, and physics as well as the impacts of climate change on human societies.
GlacierHub interviewed several of the journal’s incoming authors. They come from a wide variety of scientific backgrounds, from a focus on the Greenland ice sheets to the glaciers and water cycle of the Himalayas. Experts told us about their goals for working with the journal and their expectations for the future of the field of glaciology and climate science.
Karen Cameron is research fellow at Aberystwyth University in the United Kingdom. As a glacial microbial ecologist, she studies the effects of microbiota on glacier surfaces, and how they may contribute to ice darkening, a driver of glacier melt. Cameron is an expert on Greenland ice sheets. In one of her most recent studies, she and other researchers examined the potential expansion of Greenland’s “dark zone,” an area of the ice sheet covered in dust, black carbon, and pigmented algae.
“I look forward to contributing towards the scientific community by helping to shape and encourage outputs relating to the ecology of glacial environments. Over the coming years, there should be many exciting developments in this field. For example, I expect to see a surge in reports relating to the effect of microbial communities on reducing albedo (surface reflectivity), which enhances glacial and sea ice melt. I also expect to see more robust estimations of the contributions that glacial and permafrost microbial communities make to current and future methane budgets. Similarly, investigations into the role of microbial communities in cycling valuable nutrients and making them available to downstream ecosystems, will likely feature. Finally, there should be exciting developments in the exploration of cryospheric organisms for potential drug development and biotechnological usage.”
Shad O’Neel is a research geophysicist at the Alaska Science Center. His area of expertise includes glacier and ice sheet contributions to sea level rise, which is consequential to millions of people living along coastlines experience more frequent flooding. O’Neel also examines seismic activity at glaciers and iceberg calving events, which presents a considerable environmental hazard. Some of his more recent work focused on river discharge in subarctic Alaska suggests a link between glacier retreat, aquifer recharge, and lowland river discharge.
“I was brought on to the editorial staff to work on papers related to mountain glaciers due to my background working on them. My goal is to help promote high-quality papers related to processes and changes ongoing across Earth’s mountain glaciers. In particular, I am interested in mass balance. At the basin scale, emerging methods (e.g. ground penetrating radar) show potential to reduce uncertainties in mass change. How we aggregate observations and use them to constrain regional mass balance estimates and/or inform models is another topic I hope passes through my Journal of Glaciology inbox.”
Iestyn Barr specializes in applications of remote sensing, GIS, and modeling in high-latitude environments. As a senior lecturer at Manchester Metropolitan University, he instructs courses in glacial systems and geomorphological processes. His most recent publication compares effects of soil erosion and flooding from 1.5 degrees Celsius warming versus 2°C. Much of Barr’s previous research assesses historic glacial morphology and retreat, with substantial work done on the history, dimensions, and dynamics of the glaciers in Kamchatka, Russia.
“My goal in working for the journal is to promote glaciology in general, and particularly to continue the excellent (and long running) success of the Journal of Glaciology. One of my particular areas of interest is looking at interactions between volcanoes and glaciers (‘glaciovolcanism’). Specifically, looking at volcanic impacts on glacier dimensions and dynamics; using glacio-volcanic landforms to reconstruct past glaciers; and considering the possibility that future glacier retreat might not only be driven by, but also force, volcanic activity.”
Argha Banerjee is a glaciologist knowledgeable in the Himalayan glaciers. He is a professor of earth and climate sciences at the Indian Institute of Science Education and Research Pune. In a recent study, Banerjee, along with three other researchers, evaluated the effects of avalanches on mass balance in glaciers. They developed methods to attempt to quantify net avalanche contributions to mass balance, a feat which hasn’t been done before, and applied their methods to three Himalayan glaciers.
“My academic and personal experience over the past few years have made me appreciate the strong connections that Himalayan glaciers share with Himalayan climate, water cycle, landscape evolution, ecology, and so on. To be able to explore these connections is what makes Himalayan glaciology fascinating to me. I would love see more articles related to Himalayan climate, hydrology, and geomorphology in the journal. More studies of Himalayan snow/precipitation processes over all scales, too. I think we need to do a bit more about some of these gap areas to gain more confidence on the projections that we are making.”
Elisabeth Isaksson studies climate history and variability through analyzing ice cores in the Arctic and Antarctic. She is a senior research scientists at the Norwegian Polar Institute. Isaksson is also interested in organic contaminant pollution in snow and ice from Svalbard. Some of her previous work looks at amplified levels of black carbon in the Arctic and the impacts from climate change in the region. In places like Tibet and the Arctic, black carbon concentrations on glaciers are becoming well understood by scientists to be a strong force for increased retreat and melt.
“In the three decades that have passed since I started working with polar glaciers, the situation and challenges related to glaciology have indeed changed a lot. Back in the 1980s, we just started looking for signs of any changes that could be related to global climate warming in the Antarctic; now the signs are obvious, and things are changing rapidly. To make progress and move science forward I think that we need to find new ways of working together across scientific disciplines, which at times can be time-consuming and challenging because of our traditions in scientific training. There are also new scientific areas related to melting glaciers that are particularly interesting; one example is biological production (bacterial biomass, for instance) both on melting glaciers and at glacier fronts. As a scientific editor for an important glaciological journal I am looking forward to learn more about these research fields.”
