Roundup: Climate Park, Microbes and Variability

Park in Norway Aims  to Raise Climate Awareness

“Increased ice melting revealed in 2006–2007 many reminiscences of ancient human activity around ice patches near Mt Galdhøpiggen, Norway’s highest mountain peak. The public limited company ‘Klimapark 2469 AS’ was established to develop a heritage interpretation product and to study climate change. A 60-metre long ice tunnel is excavated in the ice patch Juvfonna, where guided walks and a display presenting climate change, archeology, Norse mythology, and glaciology are offered. […] An important outcome is the fruitful exchange of experiences, between public and private partners, tourism and science interests, amateurs and professionals, and between local, regional and national actors.”

Microbial Life Thrives in Glacier Foreland Soil

“To reveal temporal variability of archaeal and bacterial abundance, community structure, as well as microbial biomass and activity, soils of different ages (young, intermediate, mature) were sampled along a glacier foreland in the Austrian Central Alps, at the beginning (summer) and at the end (autumn) of the plant growing season. […] Our results indicate that temporal variations of microbial activities, biomass, and abundance in alpine glacier foreland soils distinctly increased along with the age of the soils and highlight the importance of sampling date for ecological studies.”

Sediments in Lake Reveals Clues About Glacier Variability

“The Arctic is warming faster than anywhere else on Earth. Holocene proxy time-series are increasingly used to put this amplified response in perspective by understanding Arctic climate processes beyond the instrumental period. However, available datasets are scarce, unevenly distributed and often of coarse resolution. Glaciers are sensitive recorders of climate shifts and variations in rock-flour production transfer this signal to the lacustrine sediment archives of downstream lakes. Here, we present the first full Holocene record of continuous glacier variability on Svalbard from glacier-fed Lake Hajeren. This reconstruction is based on an undisturbed lake sediment core that covers the entire Holocene and resolves variability on centennial scales owing to 26 dating points.”
