“Прекрасные долгие споры” между американским ученым и российским исследователем помогли прояснить несколько фундаментальных предположений о таянии вечной мерзлоты.
Changing climate in the Arctic leads to a shorter snow season but deeper snow in the depths of winter. Under the insulating snow, biological processes are accelerated leading to higher nutrient availability and carbon losses.
Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
As beavers expand their range northward into the Arctic tundra, changes in bacterial, archaeal, and fungal communities appear to be following.
Frozen flume experiments reveal the sensitivity of permafrost riverbank erosion to water temperature, bank roughness, and pore-ice content.
Higman specializes in human-powered research expeditions in Alaska’s epic landscape.
A machine learning model trained using data on the chemical composition of magmatic rocks yields comparable, if not better, results to previously developed geochemical proxies.
A visit to an Alaskan wetland with some of the world’s highest lake marsh methane emissions brings scientists one step closer to understanding the phenomenon.
The Arctic is warming up, but instead of large rivers migrating faster, they’re actually slowing down because of shrubification.
