Abstract
Isoprene, emitted by terrestrial and marine life, influences atmospheric chemistry and climate. Oceanic isoprene emissions are poorly constrained due to a lack of knowledge regarding oceanic sinks. This study uses ship-based seawater incubation experiments from various oceans to determine chemical and biological isoprene consumption. Results show a constant chemical loss rate and a biological consumption rate correlated with chlorophyll-a concentration. Isoprene consumption rates are comparable to or exceed atmospheric ventilation rates, particularly in chlorophyll-rich waters.
