Frontiers in Fluid Dynamics is an interdisciplinary workshop that aims to bring together researchers in academia, industry, and government working on all aspects of environmental and applied fluid dynamics, including forecasting, atmosphere-ocean modeling, observations and experiments.
Abstracts are invited for oral and poster presentations. Registration is free and lunch is provided. Students and early career researchers are particularly encouraged. The workshop will be followed by the AMOS-NSW public lecture and a workshop dinner in neighboring Surry Hills (self-funded).
When: 8:30am-5:30pm, 14 December 2018 (lunch provided).
Where: Bureau of Meteorology, 16/300 Elizabeth St, Sydney
Plenary lecture (9:00am): “Ensemble ocean forecasting and other next generation developments: what are the likely impacts to defence and other applications in Australia and NSW?” Dr Gary Brassington (Australian Bureau of Meteorology)
AMOS-NSW public lecture (6:00pm): “Schools weather and air quality (SWAQ): where citizen science meets urban climate research.” Dr Angela Maharaj (UNSW).
Patterns in dispersion and accumulation of plastic litter by ocean currents and eddies
Erik van Sebille, Institute for Marine and Atmospheric Research, Utrecht University, Netherlands
Date: Mon, 15/10/2018 – 4:00pm
Venue: RC-3085, The Red Centre, UNSW
Ocean currents and eddies carry floating plastic litter from coastlines into the infamous garbage patches in the centres of the gyres. However, the time scales and pathways on which this happens are unknown. In order to assess the impact of the plastic, it is key to know where it gets carried through vulnerable ecosystems.
In this talk, Dr Van Sebille will first discuss how tracks of satellite-tracked drifting buoys can be used to create a Markov model of dispersion at the surface of the ocean. He will show that this simple model accurately simulates the formation of the garbage patches, and can be used as a quick and easy tool to assess pathways of floating stuff.
Dr Van Sebille will then introduce more complicated models of passive particulates in the ocean, based on a Lagrangian description of the flow field from high-resolution models. While Lagrangian particle tracking is widely used in oceanography to track tracers, here the challenge is to make the virtual particles actually ‘behave’ like plastic.
About the speaker:
Erik is an oceanographer and climate scientist. His research focuses on how ocean currents transport heat, nutrients, marine organisms and plastic litter between different regions of the ocean.
He currently leads the “Tracking Of Plastic In Our Seas” (TOPIOS) project, funded by a 5-year (2017-2022) European Research Council Starting Grant.
Erik is the winner of the 2016 European Geosciences Union (EGU) Ocean Division Outstanding Young Scientist Award. In 2013, Erik was awarded a Discovery Early Career Researcher Award (DECRA) by the Australian Research Council.
Erik is a strong science communicator, with appearances on international television, radio and newspapers. He was a Media Fellow with the Australian Government Climate Commission and has co-hosted a section on sea level rise in Tuvalu in the international documentary series Tipping Points.
He is a sought-after international expert on oceanography, having done over 250 interviews on ocean circulation and plastic pollution with media outlets including CCN, BBC, NBC, ABC, New York Times, Wall Street Journal, Guardian, TIME magazine, AP, and Reuters.
The world’s leading society of Earth and space science, the American Geophysical Union, has elected UNSW Professor Trevor McDougall to its class of 2018 Fellows. Professor McDougall adds the award to an already impressive array of honours, including the Jaeger medal, awarded by the Australian Academy of Sciences, and the Prince Albert I medal, awarded by International Association for the Physical Sciences of the Oceans. Earlier this year, Trevor was appointed a Companion of the Order of Australia (AC).
Trevor’s research focuses on the mathematical and physical foundations of the mixing in the ocean. His work has advanced our understanding of the thermodynamics of seawater, resulting in dramatic improvements in the accuracy of climate models. He is a Scientia Professor and ARC Laureate Fellow at the School of Mathematics and Statistics at UNSW Sydney.
The American Geophysical Union (AGU) is the premier scientific body dedicated to the geophysical sciences, including atmospheric and ocean sciences, geology, hydrology, and space science.Each year, the AGU elects as Fellows scientists whose “visionary leadership and scientific excellence have fundamentally advanced research in their respective fields”. The honor is bestowed on only 0.1% of AGU’s 62,000 members from around the world.
