Alkenones as a proxy for lake temperature?

In this edition of Papers ‘n’ Cake, we discuss an article by Jaime Toney and colleagues (Toney et al., 2010) that explores the occurrence of long-chain alkenones in lacustrine settings and their application as a paleotemperature proxy. Alkenones in the marine realm: During the late 1970s and early 1980s, researchers from Delft University of Technology (Boon et al, 1978; De … More Alkenones as a proxy for lake temperature?

The leaf wax composition and stable carbon isotope value of conifers: should we care?

The stable carbon isotopic composition (δ13C) of organic matter provides key information about fundamental metabolic pathways used by the organism and the environmental conditions during formation. … More The leaf wax composition and stable carbon isotope value of conifers: should we care?
