Presentation Abstract
How does stuff wash ashore in the Salish Sea? The shores of the Salish Sea are covered in logs and trash ranging from large half-destroyed floats down to small pieces of plastic. How does it all get there? Over the past 6 years nearly 500 drifters, equipped with GPS to record positions with an accuracy of a few meters every 10-20 minutes, have been released in these waters (see drifters.eos.ubc.ca), and they have washed ashore more than 700 times. This resulted in plenty of interesting anecdotes, as tracks show a variety of surprising behaviors (including getting run down by ships). But, in addition, a statistical analysis was used to answer some interesting general questions about the Salish Sea. For example: where do things like to wash ashore? Can they escape the Salish Sea by going out into the Pacific? At what stage of the tide does stuff tend to run aground? What's the probability of grounding for items floating 20, 50, or 100m offshore? What are ocean currents like near the shore? The answers to these questions may improve modelling and policy (and they are fun science).
