November 6, 2025, by Nadja Skopljak

Florida-headquartered marine environmental consulting firm CSA Ocean Sciences (CSA) has performed an environmental baseline survey (EBS) off the coast of Mozambique for what it says is a major oil & gas company.

CSA’s project scope included water column profiling, environmental sampling, seafloor imaging, plankton net tows, sediment coring, biodiversity observations, passive acoustic monitoring of vocalizing marine mammals, the installation and recovery of metocean moorings, and a current analysis, over a period of 180 days.

The personnel also carried out air quality measurements using gravimetric and spectral absorbance methods to capture aerosolized particulates and gaseous contaminants, with the validated data to be examined for operator effectiveness and compliance over time.

CSA provided all the necessary equipment, instrumentation, and field personnel, before chartering and mobilizing a dynamically positioned vessel.

“CSA prides itself on the planning and execution of comprehensive marine survey work scopes that support responsible offshore energy development through scientifically robust data analysis,” said Gordon Stevens, CSA’s President.

“Over the past five years, CSA has managed more than 400 projects for offshore oil and gas companies around the globe, and it is this blend of operational experience and scientific expertise that places CSA in a unique position to help guide clients through the local environmental and regulatory landscape, while also prioritizing the need for sustainable E&P activities amid ballooning demand for energy around the world.”
