Celebrate the continued excellence of Michelle Mack and her recent paper in Nature
Friday, July 18, 2014
Thermokarst lakes formed across vast regions of Siberia and Alaska during the last deglaciation and are thought to be a net source of atmospheric methane and carbon dioxide during the Holocene epoch1. However, the same thermokarst lakes can also sequester carbon5, and it remains uncertain whether carbon uptake by thermokarst lakes can offset their greenhouse gas emissions. Here we use field observations of Siberian permafrost exposures, radiocarbon dating and spatial analyses to quantify Holocene carbon stocks and fluxes in lake sediments overlying thawed Pleistocene-aged permafrost. We find that carbon accumulation in deep thermokarst-lake sediments since the last deglaciation is about 1.6 times larger than the mass of Pleistocene-aged permafrost carbon released as greenhouse gases when the lakes first formed. .
How did the peacock get his eyespots? An exciting paper in Proceedings of the Royal Society B from the Kimball lab, including our own Kelly Meiklejohn as well as Rebecca Kimball and Ed Braun, will tell you more!
