Marine Investigations

KEI has performed numerous multidisciplinary marine investigations that have included baseline studies as well as impact assessments for both industrial clients and regulatory agencies. Some of these studies were very large-scale, multiyear programs led by large firms where KEI played a key role in the success of the project. Investigations have included physical and chemical oceanography; marine biology; sediment dynamics; water and sediment characterization; toxicity evaluations; and bioaccumulation testing. Many of these investigations have focused on assessment of potential impacts from marine development including oil and gas operations, wastewater discharges and outfall construction, marine terminals, and ports and harbors.


  • Oceanographic moorings

  • Meteorological monitoring

  • Fisheries

  • Zooplankton and ichthyoplankton

  • Benthic infauna and epifauna

  • Intertidal communities

  • Hard-bottom communities

  • Marine mammal observations

  • Sediment transport and dynamics

  • Forensic chemistry in water, sediments, and tissues

  • Marine toxicity and bioaccumulation

  • Water and sediment quality

KEI’s monitoring expertise includes current meter studies; water column profiling; dye dilution assessments; moorings construction and deployment; diver and ROV surveys; boat and barge operations; and the collection and analysis of water, sediment, and micro/macro organisms. KEI has performed this work throughout California in near- and offshore waters as well as in Alaska in both the Arctic and sub-Arctic regions.
