Large single-cell organisms found on past marine sediments
Good size for single-celled organisms! Benthic forams in Eocene marine sediments, Corbières #DerbyGeo pic.twitter.com/I4gu1BmeP3— Roger Suthren (@RSuthren) May 10, 2019
Past organisms living on sediments
The presence of diverse Eocene dinoflagellate assemblages in addition to intertidal sediments suggests that portions of the coal-bearing Latrobe Group were deposited in marginal-marine/tidal settings! #FossilFriday #Palynology #NewResearch pic.twitter.com/itWS5WeaD2— Vera Korasidis (@VeraKorasidis) May 10, 2019

Denitrification, Anammox, and N2 Production in Marine Sediments

Abstract: Fixed nitrogen limits primary productivity in many parts of the global ocean, and it consequently plays a role in controlling the carbon dioxide content of the atmosphere. The concentration of fixed nitrogen is determined by the balance between two processes: the fixation of nitrogen gas into organic forms by diazotrophs, and the reconversion of fixed nitrogen to nitrogen gas by denitrifying organisms. However, current sedimentary denitrification rates are poorly constrained, especially in permeable sediments, which cover the majority of the continental margin. Also, anammox has recently been shown to be an additional pathway for the loss of fixed nitrogen in sediments. This article briefly reviews sedimentary fixed nitrogen loss by sedimentary denitrification and anammox, including in sediments in contact with oxygen-deficient zones. A simple extrapolation of existing rate measurements to the global sedimentary denitrification rate yields a value smaller than many existing measurement-based estimates but still larger than the rate of water column denitrification.

Session, with feature speaker Anthony C. Janetos (Boston University), “The
National Climate Change Assessment: Climate Change Impacts in the United States
and Beyond.”
Tuesday-Thursday, January 13-15
·
4 panel discussions
