Uconn Student is Outstanding Student Paper Award Recipient

Danielle Boshers, a graduate student with Julie Granger, received an Outstanding Student Paper Award (OSPA) for her talk at the American Geophysical Union 2016 Fall Meeting. OSPAs are awarded to promote, recognize, and reward the top 3-5% of student presenters for quality research in the geophysical sciences. The topic of her presentation was Oxygen Isotope Composition of Nitrate Produced by Freshwater Nitrification.

Emily Seelen spending nine months in Sweden to study the bioavailability of methylmercury using a molecular approach

Emily Seelen, a graduate student with Robert Mason who has a NSF Graduate Fellowship, was recently awarded a GROW (Graduate Research Opportunities Worldwide) fellowship to spend nine months working with Dr. Erik Björn at the University of Umeå in Sweden. Emily left in October to begin her study: “A molecular approach to understanding the bioavailability of methylmercury associated with various sources of natural dissolved organic matter (DOM)”. The focus is on coastal and oceanic DOM interaction with methylmercury, which has been studied very little relative to its interaction with other DOM pools. Emily’s research will involve the use of high resolution instrumentation to characterize the DOM and it’s methylmercury binding capacity including x-ray near edge adsorption structure spectroscopy, Orbitrap LC-MS, and other related approaches. Emily has been a NSF Graduate Fellow since July 2013.

Prof. Pieter Visscher publishes evidence of Arsenic-based life from 2.72 billion years ago in Nature Geosciences

An article by Prof. Visscher and colleagues was recently published in Nature Geosciences.  The group assessed the chemistry and nature of cell-like globules found in 2.72-billion-year-old fossil stromatolites from Western Australia.   The globules were composed of organic carbon and arsenic and their investigation suggests that life existed as a result of arsenic cycling before the Earth’s atmosphere and ocean were oxygenated.   Details about this important finding can be found at:
