What happens next? This is not a joke but rather an important geophysical question. Particles of all types can be found settling or rising in the oceans. We present here a brief overview of typical behaviors exhibited by the three main types of particles: solid, fluid, and porous. We focus on interactions between these particles and an ambient stratification. Solid particles may be present in sufficiently large numbers as to create their own density gradients. Fluid particles are separated from the ambient by a fluid-fluid interface that can have a variable surface tension. This in turn leads to sudden accelerations due to Marangoni effects. Porous particles are able to exchange heat or salt with the ambient, but they do so slowly, via diffusive effects, which results in seemingly stagnant periods.</span><span style="color:black"> </span></p></div><div style="font-family:Arial,Helvetica,sans-serif"><p class="MsoNormal" style="text-align:center"><span style="color:black">Bio:<u></u><u></u></span></p></div><div id="m_-4625721781421304128m_-4510783189421802837gmail-m_-5796115816665453277x_x_x_divtagdefaultwrapper" style="font-family:Arial,Helvetica,sans-serif"><div style="margin-bottom:12pt"><p class="MsoNormal" style="text-align:center"><span style="color:black">Professor Blanchette did his undergraduate studies in Montréal, before obtaining a Ph.D. in Mathematics at MIT.

In 2006, he joined the brand new Applied Mathematics program at UC Merced, where he has been since and which he now chairs. He research is in fluid dynamics in general, with an emphasis on multiphase flows and modeling.</span></p></div></div></div><div style="font-family:arial,sans-serif"><p class="MsoNormal">When: Sept 6, Thursday, 12pm – 1pm<u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">Where: SE2-302<u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">Coffee will be provided, please bring your own mugs.<u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">We look forward to seeing you,<u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">Nate & Jing<u></u><u></u></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">Organizers for Fall 2018: Nate Bogie and Jing Yan<u></u><u></u></p><p class="MsoNormal">Faculty coordinator: Asmeret Asefaw Berhe</p></div><br></div></div></div></div>
