Biological Investigations
KEI has performed marine biological studies that range from monitoring the impacts of offshore drilling operations to understanding the dynamics of benthic and intertidal communities. Our terrestrial biological capabilities range from stream bioassessment surveys to threatened/endangered species monitoring. For the past 50 years, KEI has proven our ability to plan, implement, and conduct comprehensive ecological studies that encompass a diversity of biological regimes. Studies have addressed existing and potential impacts to ecosystems due to natural and human-induced alterations to the environment.
