BEES Graduate Research Seminar: David Burdige
Thursday, April 25, 2013
12:00 PM-1:00 PM
Title: "Dissolved organic matter cycling in marine sediments and its linkages to oceanic elemental cycles"
Speaker: David Burdige, Old Dominion University, Department of Ocean, Earth and Atmospheric Sciences (hosted by Dr. David Velinsky)
Description: Dissolved organic carbon (DOC) is an important intermediate in organic carbon remineralization and may also play a role in carbon burial and preservation in marine sediments. Net DOC production in sediments results in a benthic flux of this material to the water column, and the magnitude of this flux may be comparable to the riverine DOC flux to the oceans. This talk will review past work in this area and discuss the results of recent studies in which isotopic studies of DOC (both 13C and 14C) are used to further define the sources and reactivity of sediment pore water DOC.
Refreshments will be served.
The BEES Graduate Research Seminar is a weekly series of scientific presentations by faculty, graduate students and outside speakers. The seminars are opportunities for learning about and discussing ongoing research in the department and current issues in biodiversity, earth and environmental science.
