This question will be asked by Dr Matt Donnelly, Lead Data Scientist, UK Argo Programme. The oceans play a key role in the climate and provide a habitat for a wide range of marine life, but with an average depth of 3.7km and a surface area of 360 million km2, how on earth do you collect the data to understand its physical properties, how it moves, and how it supports life?

Find out about the robotic Argo floats used to sustain our observations of this dynamic underwater world.

Dr Donnelly is also the organizer of Kirkby SciBar.
