  • Ancient DNA techniques : applications for deep-water corals 

    Waller, Rhian G.; Adkins, Jess F.; Robinson, Laura F.; Shank, Timothy M. (University of Miami - Rosenstiel School of Marine and Atmospheric Science, 2007-11-01)
    The potential applications of ancient DNA (aDNA) techniques have been realized relatively recently, and have been revolutionized by the advent of pCR techniques in the mid 1980s. Although these techniques have been proven ...
  • Deep-sea scleractinian coral age and depth distributions in the northwest Atlantic for the last 225,000 years 

    Robinson, Laura F.; Adkins, Jess F.; Scheirer, Daniel S.; Fernandez, Diego P.; Gagnon, Alexander C.; Waller, Rhian G. (University of Miami - Rosenstiel School of Marine and Atmospheric Science, 2007-11-01)
    Deep-sea corals have grown for over 200,000 yrs on the New England Seamounts in the northwest Atlantic, and this paper describes their distribution both with respect to depth and time. Many thousands of fossil scleractinian ...
  • Dynamic intermediate ocean circulation in the North Atlantic during Heinrich Stadial 1 : a radiocarbon and neodymium isotope perspective 

    Wilson, David J.; Crocket, Kirsty C.; van de Flierdt, Tina; Robinson, Laura F.; Adkins, Jess F. (John Wiley & Sons, 2014-11-20)
    The last deglaciation was characterized by a series of millennial-scale climate events that have been linked to deep ocean variability. While often implied in interpretations, few direct constraints exist on circulation ...
  • GEOTRACES IC1 (BATS) contamination-prone trace element isotopes Cd, Fe, Pb, Zn, Cu, and Mo intercalibration 

    Boyle, Edward A.; John, Seth G.; Abouchami, Wafa; Adkins, Jess F.; Echegoyen-Sanz, Yolanda; Ellwood, Michael J.; Flegal, A. Russell; Fornace, Kyrstin; Gallon, Celine; Galer, Steve; Gault-Ringold, Melanie; Lacan, Francois; Radic, Amandine; Rehkamper, Mark; Rouxel, Olivier J.; Sohrin, Yoshiki; Stirling, Claudine H.; Thompson, Claire; Vance, Derek; Xue, Zichen; Zhao, Ye (Association for the Sciences of Limnology and Oceanography, 2012-09)
    We report data on the isotopic composition of cadmium, copper, iron, lead, zinc, and molybdenum at the GEOTRACES IC1 BATS Atlantic intercalibration station. In general, the between lab and within-lab precisions are adequate ...
  • Interlaboratory study for coral Sr/Ca and other element/Ca ratio measurements 

    Hathorne, Ed C.; Gagnon, Alexander C.; Felis, Thomas; Adkins, Jess F.; Asami, Ryuji; Boer, Wim; Caillon, Nicolas; Case, David H.; Cobb, Kim M.; Douville, Eric; deMenocal, Peter B.; Eisenhauer, Anton; Garbe-Schonberg, Dieter; Geibert, Walter; Goldstein, Steven L.; Hughen, Konrad A.; Inoue, Mayuri; Kawahata, Hodaka; Kolling, Martin; Cornec, Florence L.; Linsley, Braddock K.; McGregor, Helen V.; Montagna, Paolo; Nurhati, Intan S.; Quinn, Terrence M.; Raddatz, Jacek; Rebaubier, Helene; Robinson, Laura F.; Sadekov, Aleksey; Sherrell, Robert M.; Sinclair, Dan; Tudhope, Alexander W.; Wei, Gangjian; Wong, Henri; Wu, Henry C.; You, Chen-Feng (John Wiley & Sons, 2013-09-23)
    The Sr/Ca ratio of coral aragonite is used to reconstruct past sea surface temperature (SST). Twenty-one laboratories took part in an interlaboratory study of coral Sr/Ca measurements. Results show interlaboratory bias can ...
  • Low reservoir ages for the surface ocean from mid-Holocene Florida corals 

    Druffel, Ellen R. M.; Robinson, Laura F.; Griffin, Sheila; Halley, Robert B.; Southon, John R.; Adkins, Jess F. (American Geophysical Union, 2008-05-13)
    The 14C reservoir age of the surface ocean was determined for two Holocene periods (4908–4955 and 3008–3066 calendar (cal) B.P.) using U/Th-dated corals from Biscayne National Park, Florida, United States. We found that ...
  • Primary U distribution in scleractinian corals and its implications for U series dating 

    Robinson, Laura F.; Adkins, Jess F.; Fernandez, Diego P.; Burnett, Donald S.; Wang, S.-L.; Gagnon, Alexander C.; Krakauer, Nir (American Geophysical Union, 2006-05-24)
    In this study we use microsampling techniques to explore diagenetic processes in carbonates. These processes are important as they can affect the accuracy of U series chronometry. Fission track maps of deep-sea scleractinian ...
  • Temporal stability of the neodymium isotope signature of the Holocene to glacial North Atlantic 

    van de Flierdt, Tina; Robinson, Laura F.; Adkins, Jess F.; Hemming, Sidney R.; Goldstein, Steven L. (American Geophysical Union, 2006-11-25)
    The neodymium isotopic composition of marine precipitates is increasingly recognized as a powerful tool for identifying changes in ocean circulation and mixing on million year to millennial time-scales. Unlike nutrient ...
