Unraveling Holocene Arctic climate dynamics using sediments from Hajeren, a glacier-fed lake on Mitrahalvøya (RiS ID 6663)

The Arctic shows an amplified response to current warming and is rapidly changing. Data on past polar climate variability is scarce and hampered by a low resolution. My PhD research aims to provide high-resolution data for the Holocene to put current warm ing into perspective. To this end, I analyze sediment records from glacier-fed lakes on Mitrahalvøya, Svalbard. Glaciers are susceptible to climate change as demonstrated by their response to current warming. Glacier-fed lakes therefore record a sensitive climate signal, driven by hydrological changes and temperature variations.
