Tamaryn Morris

Tamaryn Morris is a physical oceanographer with extensive field experience in the South-West Indian and South Atlantic Oceans, using a range of ocean-observing instruments and platforms. Her PhD thesis used high-resolution Argo-float profiling to study mesoscale dynamics in the southern Mozambique Channel and the Agulhas Current. Her research interests lie in boundary currents, mesoscale eddies, and the use of autonomous ocean-observing platforms to study them.

She collaborates with researchers on national, regional and international panels. She is the South African focal point on the Argo Steering Team (AST), a Director and Board Trustee of the Partnership for Observations of the Global Ocean (POGO), and an expert on the Ocean Observations Physics and Climate (OOPC) panel of the Global Climate Observing System (GCOS). She is also co-lead of the GOOS Co-Design Boundary Current Exemplar Project, a UN Ocean Decade-endorsed programme.

Tamaryn is the Ocean and Polar Coordinator at the SAEON Egagasini Node, where she oversees a team of ten delivering the marine and polar ocean-observing objectives of the South African marine science community. She also led the Ocean20 social-engagement group under South Africa's 2025 G20 Presidency.
