  • Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere 

    Hammes, Karen; Schmidt, Michael W.I.; Smernik, Ronald J.; Currie, Lloyd A.; Ball, William P.; Nguyen, Thanh H.; Louchouarn, Patrick; Houel, Stephane; Gustafsson, Orjan; Elmquist, Marie; Cornelissen, Gerard; Skjemstad, Jan O.; Masiello, Caroline A.; Song, Jianzhong; Peng, Ping'an; Mitra, Siddhartha; Dunn, Joshua C.; Hatcher, Patrick G.; Hockaday, William C.; Smith, Dwight M.; Hartkopf-Froder, Cristoph; Bohmer, Axel; Luer, Burkhard; Huebert, Barry J.; Amelung, Wulf; Brodowski, Sonja; Huang, Lin; Zhang, Wendy; Gschwend, Philip M.; Flores-Cervantes, D. Xanat; Largeau, Claude; Rouzaud, Jean-Noel; Rumpel, Cornelia; Guggenberger, Georg; Kaiser, Klaus; Rodionov, Andrei; Gonzalez-Vila, Francisco J.; Gonzalez-Perez, Jose A.; de la Rosa, Jose M.; Manning, David A. C.; Lopez-Capel, Elisa; Ding, Luyi (2007)
    Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ...

  • Diagnostic Foraminifera and Paleocology of the Pungo River Formation, Central Coastal Plain of North Carolina 

    Katrosh, Mark R.; Snyder, Scott W. (1982-12)
    Benthic foraminiferal assemblages of the Pungo River Formation (middle Miocene) from the central North Carolina Coastal Plain indicate deposition in continental shelf environments. In Beaufort and Pamlico Counties, part ...

  • Impact of Hurricane Katrina (2005) on deltaic evolution and shelf organic carbon cycling 

    Allison, M.A.; Dellapenna, T.M.; Gordon, Elizabeth S.; Mitra, Siddhartha; Petsch, S.T. (2010)
    Sediment cores from the continental shelf adjacent to the Mississippi River delta immediately after the passage of Hurricane Katrina were used to examine the magnitude, and implications for the carbon budget, of sediment ...

  • Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico 

    Mitra, Siddhartha; Kimmel, David G.; Snyder, Jessica; Scalise, Kimberly; McGlaughon, Benjamin D.; Roman, Michael R.; Jahn, Ginger L.; Pierson, James J.; Brandt, Stephen B.; Montoya, Joseph P.; Rosenbauer, Robert J.; Lorenson, Thomas D.; Wong, Florence L.; Campbell, Pamela L. (2012)
    Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ...

  • Oceanic loading of wildfire-derived organic compounds from a small mountainous river 

    Hunsinger, Glendon B.; Mitra, Siddhartha; Warrick, Jonathan A.; Alexander, Clark R. (2008)
    Small mountainous rivers (SMRs) export substantial amounts of sediment into the world's oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and ...
