Study finds deep ocean is source of dissolved iron in Central Pacific
WHOI
A new study led by scientists at the Woods Hole Oceanographic Institution points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean. This finding highlights the vital role ocean mixing plays in determining whether deep sources of iron reach the surface-dwelling life that need it to survive.

SOCIETY NEWS


Goldschmidt2018 Boston
GS
It is with great pleasure that GS and EAG announce the venue and dates for the 28th Goldschmidt Conference! After careful investigation of a series of venues on the U.S. eastern seaboard a competitive bid from the John B. Hynes Veterans Convention Centre in Boston was selected to host the 2018 Goldschmidt from Aug. 11-17. New England and the greater Boston area offer not only an extraordinary nexus of outstanding scientific institutions (many of whom will be involved in the conference planning and organization), but also a superb location for field trips and social events – all located close to major transportation hubs. A special focus of recent Goldschmidt Conferences has been on community building — with a particular emphasis on the group that is the foundation and future of geochemistry — the students and early career scientists. Mentoring programs and other innovations to attract and support our growing and increasingly international community will be a cornerstone as well.

Interior of the Earth Gordon Research Conference and Seminar — June 7-12 and June 6-7, 2015
GRC
Please consider attending the 2015 Interior of the Earth Gordon Research Conference (GRC) (June 7-12) and Gordon Research Seminar (GRS) (June 6-7), both at Mt. Holyoke College, MA USA. This year's GRC has the theme "Surface Connections. As always, the GRC will include presentations on contemporary topics of interest from those actively engaged in new research and will facilitate extensive discussion after talks. The GRS has the theme "The Structure, Properties and Evolution of Plate Boundariesa" and is meant for post-docs, graduate students, and very junior research scientists/faculty. More detailed programs and meeting info are available at http://www.grc.org/programs.aspx?id=12544 (GRC) and http://www.grc.org/programs.aspx?id=14761. (GRS).
