Earlier ice melt increases hypolimnetic oxygen despite regional warming in small Arctic lakes

open access: yesLimnology and Oceanography Letters
Although trends toward earlier ice‐out have been documented globally, the links between ice‐out timing and lake thermal and biogeochemical structure vary spatially.

Signature of explosive volcanic eruptions in the sediments of a high-altitude Swiss lake [PDF]

open access: yes, 2018
The analysis of 125years of well-dated varved sediments in Lake Silvaplana, located at 1,791m a.s.l. in the Upper Engadine region of south-eastern Switzerland, reveals that 7 out of the 8 climatically relevant explosive volcanic eruptions between A.D ...

Geographic Variation of Cirques on Iceland: Factors Influencing Cirque Morphology

open access: yes, 2017
Cirques are one of the most common glacial landforms in alpine settings. They also provide important paleoclimate information (e.g. Meierding 1984; Evans 2006). The purpose of this study is to fill in gaps in the climate record of Iceland by conducting a
