Iceberg Ahead! A New Study Finds Way to Avert Disaster

“When performing offshore operations in the Arctic, there are several challenges. One of those challenges is the threat of icebergs on offshore structures and vessels. Icebergs can exert extremely high loads on vessels, offshore platforms, and seabed installations.”

 Glaciers Retreat Toxic Metals Are on the Move in Tibet

“In mountain ecosystems, the most important natural source of trace metals is from the weathering of parent materials. However, in recent decades, the metals in mountain regions are mainly from anthropogenic sources including mining, refinement, and fuel combustion. Considering the toxicity of trace metals, it is necessary to investigate and evaluate their mobility and eco-risk in mountain ecosystems.”

With Red and Green Snow, Algae Just Misses Christmas Season

“We demonstrate that green and red snow clearly vary in their physico-chemical environment, their microbial community composition and their metabolic profiles. For the algae this likely reflects both different stages of their life cycles and their adaptation strategies. ”
