The History Of Human Impacts In The Clear Lake Watershed (California) As Deduced From Lake Sediment Cores *

Peter J. Richerson, Thomas H. Suchanek, Jesse C. Becker, Alan C. Heyvaert et autres

120 We have raised sediment cores to investigate multiple stresses on Clear Lake, CA over the past 250 years. Earlier work suggested the hypothesis that the use of heavy earthmoving equipment was responsible for erosion, mercury, and habitat loss stresses. Such stresses …

Incandescence‐based single‐particle method for black carbon quantification in lake sediment cores

Nathan J. Chellman, Joseph R. McConnell, Alan C. Heyvaert, Boris Vannière et autres

Abstract Refractory black carbon (rBC) is an important contributor to radiative forcing, so quantifying rBC emissions and transport is critical for accurate climate modeling. Formed during incomplete combustion of fossil fuels or biofuels, rBC is emitted to the atmosphere from large wildfires …
