10/10-13/2018 – Chris visited the University of British Columbia to give two seminars on trace element residence times in the ocean and the protactinium/thorium proxy in paleoceanography. Had a wonderful time meeting old and new colleagues and seeing Vancouver! https://twitter.com/chrishayes228/status/1051198684690407424
8/29/2018 – Two new graduate students have started in the Hayes Lab, Ally Savoie and Neil Redmond. Look out for great stuff from them!
8/13-17/2018 – Sam and Chris gave posters at Goldschmidt, the annual meeting of the Geochemical Society, in Boston. Here we are out to dinner with some other Golden Eagles from USM’s Geochemistry group. Read our abstracts here and here.
8/8/2018 – New paper out! Chris and a team of GEOTRACES colleagues estimated the replacement times of many elements of the periodic table in the North Atlantic Ocean using thorium isotope and trace element data. How long would it take to replace your favorite element in the ocean? Find out at Global Biogeochemical Cycles.
6/19-21/2018 – Chris attended the mid-grant meeting in Huntington Beach, California for our National Academies Keck Future Initiative (NAKFI) project to create a virtual experience of life in the deep ocean.
3/20-23/2018 – Chris and Sam visited the Lamont-Doherty Earth Observatory at Columbia University to sample Southern Ocean sediments (cores RC13-259 and RC13-254) for our project on past changes in ocean circulation using authigenic uranium as a proxy (good work Sam!). Chris was also on the PhD defense committee of LDEO student (now Dr.) Alexandra Bausch (congrats Ali!).
3/7-9/2018 – Chris participated in the pre-cruise planning meeting for the upcoming GEOTRACES transect cruise between Alaska and Tahiti, held at Old Dominion University in Norfolk, VA.
2/10-17/2018 – Chris attended the AGU/ASLO/TOS Ocean Sciences Meeting in Portland, OR, and spoke on a GEOTRACES synthesis paper deriving the fluxes and residence times across the periodic table in the North Atlantic as well as a town hall to organize study of trace elements and isotopes in the Gulf of Mexico.
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.
