12/18/2017 – Chris gave an invited talk at the 2017 AGU Fall Meeting in New Orleans about the connection between Saharan dust transport and hurricanes. Read the abstract here.
11/4/2017 – We have gotten another grant funded by the National Science Foundation to analyze thorium and protactinium on the next U.S. GEOTRACES survey from Alaska to Tahiti, together with colleagues from Columbia University and the University of Minnesota. We are currently seeking a graduate student to work on this project (https://www.usm.edu/marine/student-opportunities).
6/12/2017 – Two new grants have started this summer! (1) Supported by the National Science Foundation, we will be looking at sediment records from the Southern Ocean in the context changing circulation, melting ice sheets, and uranium geochemistry (see here). (2) The National Academies are supporting a pilot project to develop a virtual reality experience about life in the deep ocean. See press release here.
5/4/2017 – Chris is giving an invited talk at PAGES (Past Global Changes) Open Science meeting in Zaragoza, Spain next week on using the protactinium/thorium ratio in sediments as a proxy for past ocean circulation. See program and abstract here.
2/28/2017 – Chris gave a talk about trace metal variations at Station ALOHA in the North Pacific Ocean at the Association for the Sciences of Limnology and Oceanography (ASLO) Aquatic Sciences Meeting in Honolulu. Read the abstract here.
1/12/2017 – We have a new article coming out in Global Biogeochemical Cycles about thorium, uranium and other trace metals between Barbados and Bermuda, including work from Jeff Rosen‘s undergrad thesis! Paper online here. Highlight written up on GEOTRACES.org
1/3/2017 – Chris is looking for a new graduate student to start in Fall 2017. See ad here.
12/12/2016 – Chris is presenting at the 2016 AGU Fall Meeting in San Francisco (14:25-14:45, Moscone West 2012). He’ll talk about work on uranium isotopes in the Southern Ocean as a new proxy for changing oxygenation in the past ocean. See abstract here.
