Short summary

Our isoprene data from field measurements in the mixed layer from the Indian Ocean and the eastern Pacific Ocean show that the ability of different phytoplankton functional types to produce isoprene seems to be mainly influenced by light, ocean temperature, salinity, and nutrients. By calculating in-field isoprene production rates, we demonstrate that an additional loss is needed to explain the measured isoprene concentration, which is potentially due to degradation or consumption by bacteria.
