Oceanswell is Sri Lanka's first marine conservation and research education organisation and was founded by marine biologist Asha de Vos.
Oceanswell is known for the Blue Whale Project which is the first long-term study on blue whales in the Northern Indian Ocean. The project focuses on the conservation of blue whales from threats such as ship strikes. De Vos founded the Blue Whale Project which is the flagship project of Oceanswell.
Research includes the COVID-19 and Fisheries Project, natural variability of Mount Lavinia Beach, effectiveness of shark fishing bans and advocacy research against beach nourishments conducted without Environmental Impact Assessments. Recent publications advocate against 'parachute science' which is practice of Western scientists collecting data in developing countries and leaving without training in the region.
Oceanswell conducts educational sessions for school children, skill building courses, marine conservation field courses, monthly gatherings for individuals of different fields to discuss marine conservation issues, rscues stranded marine animals and conducts awareness on species.
