description: aquatic biomarker
basis: As in Pahnke et al., 2007, Paleoceanography: ""in areas of strong contrast between the d D value of precipitation and seawater, and high amounts of rainfall (e.g., in the tropics close to river deltas), any changes in alkenone d D values caused by species or growth rate variations are likely to be secondary to the first order effects caused by freshwater fluxes."

scope: climate

scope: climate
scope: climate
basis: Our results illustrate that changes in atmospheric circulation can trigger changes in precipitation isotopes in a counter-intuitive manner that ultimately impacts surface salinity estimates based on seawater isotopic values.
