Abstract Environmental DNA (eDNA) is a convenient biodiversity monitoring tool, and many studies have focused on river and coastal areas, while deep‐water oceanic surveys are rare. However, using eDNA techniques to learn about oceanic communities m

We conducted shipboard observations in Funka Bay, Hokkaido, Japan, in 2015, 2016 and 2019 to observe temporal variations of isoprene (C5H8) concentration in water and sediment. We found increases in C5H8 concentrations below and within the euphotic z
