New paper alert! Former SES PhD student Leah Marshall alongside 2 SES profs, 3 former SES undergrads and colleagues investigate 15,800 years of carbon accumulation and environmental change in an Arctic watershed using lake sediment cores. Check it out! doi.org/10.1080/1523...

#newarticle by Marshall et al. investigates a unique pairing of Holocene lake sediment & soil records from central Alaska, highlighting the importance of sediment burial efficiency on carbon accumulation in high-latitude lakes: doi.org/10.1080/15230430.2025.2523083

Ultimately, the carbon sequestration potential of this and other Arctic lakes is highly dependent upon the rate of sediment delivery.

This unique pairing of lake and hillslope sediment records allowed us to investigate millennial-scale changes in carbon accumulation across a watershed.

Check out our new paper about carbon, productivity and climate over 15,800 years in central Alaska. Out in @aaarjournal.bsky.social this paper pairs new sediment records from Eight Mile Lake with soil cores from the adjacent hillslope.

A 15,800 year record of productivity, carbon accumulation and environmental change at Eight Mile Lake and its catchment, central Alaska
Despite their efficient burial of organic carbon (OC), the role of high-latitude lakes in storing and processing OC under changing climates is poorly understood. We investigate a 15,800 year sedime...
