Dr. Knap's primary research focuses include oceanography, organic geochemistry, environmental science, atmosphere/ocean interactions, oil pollution and dispersant use, and effects of contaminants on the marine environment. Global climate change is another area of interest, particularly climate instability, business/science interactions, renewable energy, marine derived bio-fuels, ocean genomics, ocean acidification. He was Founder and Principal Investigator of the NSF-funded Bermuda Atlantic Time-series Study (BATS) off Bermuda. He was also the Principal Investigator for 30 years of Hydrostation S, founded in 1954 and the longest continuous time-series in the Ocean, also funded by NSF. He most recently was appointed to the Gulf Research Board of the US National Academy of Sciences.
