Investigation of the UK37’ vs. SST relationship for Atlantic Ocean suspended particulate alkenones: An alternative regression model and discussion of possible sampling bias

Controls on Alkenone Carbon Isotope Fractionation in the Modern Ocean

“…Algae have a Lagrangian history and the conditions at the depth of collection are not necessarily identical to those at the depth of production, a phenomenon that has also been observed for alkenone unsaturation ratios (cf. Conte et al, 2006;Gould et al, 2017). Furthermore, in the majority of the water-column samples, we estimated irradiance from satellite-based mean monthly climatological datasets because the measurements were not typically made during alkenone sampling.…”
