What's new in the group?
- Excellent new paper by Sally Warner, in which she parses the bottom pressure field into different dynamical parts - some of which contribute to form drag. One key finding is that the usual way of estimating barotropic to baroclinic conversion is a very poor estimate near the headland. Warner, S. J., and P. MacCready (2014), The dynamics of pressure and form drag on a sloping headland: Internal waves versus eddies, J. Geophys. Res. Oceans, 119, doi:10.1002/2013JC009757.

- New paper on modeling Harmful Algal Bloom transport: S. N. Giddings, P. MacCready, B. M. Hickey, N. S. Banas, K. A. Davis, S. A. Siedlecki, V. L. Trainer, R. M. Kudela, N. A. Pelland, and T. P.

- Sarah Giddings, a postdoc in my group 2011-2013, has taken a faculty job at SIO-UCSD. Congratulations, Sarah!
- My recent 4 month mini-sabattical at Microsoft Research Connections is briefly described here. I'll be talking more about this work at the Physical Oceanography lunch seminar on Wednesday May 28, 2104. Room 425 Ocean Sciences Building at UW.
- 4/15/2014 Matthew Alford and I published a paper in GRL about observations of flow in Juan de Fuca Canyon, which cuts across the Washington shelf. It is an important place because it forms a conduit to bring relatively deep, nutrient rich, low DO, low pH water to the incoming branch of the Salish Sea estuarine circulation. The transport of this current is huge, being comparable to the Amazon River, and 20-30 times bigger than all the rivers flowing into the Salish Sea and Puget Sound. That is why we call this the "headwaters of Puget Sound." Here is a short TV story from King 5, and a great UW press release. The paper citation is: Alford, M. H., and P. MacCready (2014), Flow and mixing in Juan de Fuca Canyon, Washington. Geophys. Res. Lett., 41, doi:10.1002/2013GL058967. Here is a nice story on the subject in the Environmental Monitor.
- 4/4/2014 Check out the Vorticity Drifters!
- New review paper on estuaries: Geyer, W. R., and P. MacCready (2014) The Estuarine Circulation. Annu. Rev. Fluid Mech. 2014. 46:175–97, 10.1146/annurev-fluid-010313-141302. [URL]
- 12/2013 Our Coastal Modeling Group has been funded by Washington State, through the new Washington Ocean Acidification Center, to deverlop a daily forecast ocean model for the Washington Coast and Puget Sound. The model will include carbon chemistry, to allow prediction of Ocean Acidification. Here is a recent news story from the College of the Environment, which appeared in this newsletter.
- Here is a wonderful article by Anna Wargula, a student in our recent Friday Harbor Summer School "Estuarine and Coastal Fluid Dynamics," on the joys of doing recearch from a ship in Admiralty Inlet.
- Dr. MacCready joins the new Encyclopedia of Puget Sound as a member of the Editorial Board, handling all contributions on the Sound physical system, from tides and currents to geology and weather, October 2012.
- New website for the PNWTOX Modeling effort
- New website for the UW Coastal Modeling Group
- Congratulations to Dr. Sally Warner who successfully completed her PhD in September 2012. Sally will be joining Jim Moum's group at OSU for a postdoc, after traveling the world for 6 months with the help of a Bonderman Fellowship. Sally also received First Place for Best Graduate Student Talk at the Nov. 2011 CERF meeting. We'll miss you Sally!
- Congratulations to Dr. Sarah Giddings who recently received a highly-competetive NSF postdoctoral fellowship to continue work in our group. She will be studying the physics controlling the exchange of water between estuarine and coastal systems, with a focus on the remarkable flow reversal events that occur when Columbia River plume water reaches to the mouth of the Strait of Juan de Fuca.
- Here is a video of Dr. MacCready giving a seminar at NCAR in Boulder, CO, 10/16/2012, "An overview of the physics of estuarine circulation, with biogeochemical implications."
- Dr. MacCready interviewed about Tsunami Debris 3/30/2012. http://www.king5.com/news/quake/Growing-urgency-over-Japan-tsunami-debris-heading-our-way-145206105.html
