Infochemicals in the Ocean

Civil and Environmental Engineering

Added almost 6 years ago | 00:00:45 | 14579 views

Marine microbes — though invisible to the naked eye — perform functions that are vital for the health of the ocean. With no vision or hearing, they navigate their environment by following chemical signals. One of these chemicals, DMSP, e...
