Northern Ecosystems are Shaped by Snow
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.

Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
