Discover Sri Lanka's ocean through research, education, field stories and experiences that bring marine science closer to everyone.
Sayura (සයුර) is the Sinhala word for "ocean." eSayura takes that name as its purpose: to bring the ocean, vast, largely unseen, and often misunderstood, a little closer to the people who live beside it.
Three ways to explore, learn, and understand the ocean.
Discover Sayura Pasela, Ocean Explorer, and CMST, each offering a different path into ocean education, discovery, and research.
From reef ecology to port biofouling, plain-language explainers of the science, each linking through to the research behind it.
A coastline understood well enough to be protected, by scientists, by students, and by the people who depend on it every day.
Research, field discoveries and ideas shaping the future of Sri Lanka's ocean.
A widely cited global study ranked Sri Lanka among the world's worst contributors to ocean plastic pollution. New field-based research from CMST and collaborators at CSIRO Australia challenges the assumptions behind that ranking and makes the case for policy built on local scientific evidence.
Following recent floods, researchers returned to the upper Sitawaka and Kelani river systems in search of the critically endangered Asoka barb. Their observations highlight growing threats to one of Sri Lanka's most range-restricted freshwater fishes.
A new CMST study traced microplastics across 15 sites along the Attanagalu River, from its headwaters to the river mouth, revealing how plastic pollution moves downstream toward Sri Lanka's coastal seas.
A World Ocean Day keynote examined the urgent pressures facing Sri Lanka's seas, from declining fisheries and damaged coral reefs to maritime disasters, pollution and fragmented ocean governance.
