Marine sediment as a likely source of methyl and ethyl iodides in subpolar and polar seas

Abstract

Elevated methyl and ethyl iodide concentrations in bottom waters may be linked to diatom aggregates and phytodetritus from the spring bloom settling to the sea floor, according to shipborne observations and laboratory-based incubation experiments in the Bering and Chukchi Seas and Funka Bay, Japan.
