<u>Title</u>: <span lang="EN-US">Whose plastic is that? Combining
ocean physics with Bayesian inference to attribute microplastic
sources and sinks<br>
<u>Presenter</u>: Eric van Sebille, </span><span lang="EN-US"><span lang="EN-US">professor of oceanography and public engagement at
Utrecht University<br>
<u>Abstract</u>: </span></span><span lang="EN-US">The world's
ocean currents can potentially transport material like plastic
over vast scales, connecting sources on one continent to impacts
on another. On the other hand, it had recently become clear that
most plastics found at any particular location are relatively
local, often originating from within the same country. Effective
policies to reduce the impact of plastic pollution require
knowledge of whose plastic ends up where.</span><span lang="EN-US">
</span><span lang="EN-US">In this seminar, I will present some
recent work on using a Bayesian framework to analyze the sources
of plastics found on beaches around the world. The input to this
analysis comes from Lagrangian ocean analysis simulations with the
OceanParcels.org tool, which I will also showcase. I will
particularly highlight results from the Indian Ocean, the
Galapagos, the South Atlantic and the North Sea.

<p class="MsoNormal"><span lang="EN-US"><u>Short bio</u>: </span><i><span lang="EN-US">Erik van Sebille is professor of oceanography and
public engagement at Utrecht University. He investigates how
ocean currents move 'stuff' around. He is co-author of the
textbook 'Ocean Currents - Physical Drivers in a Changing
World' with Professor Robert Marsh. Until 2022, he led the ERC
Starting Grant project 'Tracking Of Plastics in Our Seas'. In
parallel to his ongoing work on physical oceanography, he has
recently started a new research team on how scientists can be
effective and inclusive in their communication and engagement
with society, specifically on the climate crisis.</span></i></p>

visiting FSU and COAPS Monday November 14 to Thursday November
17. Please contact me if you want to schedule some time with
him.</span><i><span lang="EN-US"><br>
