The geodynamic and limnological evolution of Balkan Lake Ohrid, possibly the oldest extant lake in Europe

Boreas, Volume 52, Issue 1, Page 1-26, January 2023., 2023
Studies of the upper 447 m of the DEEP site sediment succession from central Lake Ohrid, Balkan Peninsula, North Macedonia and Albania provided important insights into the regional climate history and evolutionary dynamics since permanent lacustrine conditions established at 1.36 million years ago (Ma).

Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

Millennial‐scale oscillations and an environmental regime shift around the Middle to Late Holocene transition in the North Atlantic region based on a multiproxy record from Isfjorden, West Spitsbergen

Boreas, Volume 52, Issue 1, Page 42-59, January 2023., 2023
Palynological and sedimentological analyses were performed on the sediment core HH16‐1205‐GC retrieved from the central Isfjorden, West Spitsbergen. The sequence, which spans the last 7000 years, revealed an overall cooling trend with an important climate shift between 4.4 and 3.8 cal. ka BP, in addition to millennial‐scale oscillations.

Shrubs Strongly Influence Snow Properties in Two Subarctic Watersheds

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding changes in snow distribution in permafrost ecosystems is fundamental to predicting their response to future climate change. The expansion of tall shrubs into tundra ecosystems can trap snow and insulate permafrost ecosystems during the winter, but the overall insulation effect is dependent upon many ecosystem properties. To study

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.

Quantifying Permafrost Degradation Processes: Real‐Time Analysis Using Environment‐Based Particle Image Velocimetry and Weather Data

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT We present an innovative approach to understanding permafrost degradation processes through the application of new environment‐based particle image velocimetry (E‐PIV) to time‐lapse imagery and correlation with synchronous temperature and rainfall measurements.
