Short summary
The preservation and distribution of alkenones – organic molecules produced by marine algae – in marine sediments allows us to reconstruct past variations in sea surface temperature, primary productivity and CO2. Here, we explore the impact of remobilization and lateral transport of sedimentary alkenones on their fate in marine sediments. We demonstrate the pervasive influence of these processes on alkenone-derived environmental signals, compromising the reliability of related paleorecords.
