Ice Age‐Holocene Similarity of Foraminifera‐Bound Nitrogen Isotope Ratios in the Eastern Equatorial Pacific
Studer, Anja S.; Mekik, Figen; Ren, Haojia; Hain, Mathis P.; Oleynik, Sergey; Martínez‐García, Alfredo; Haug, Gerald H.; Sigman, Daniel M. (Paleoceanography and Paleoclimatology, 2021-05-19)Bulk sediment δ15N records from the eastern tropical Pacific (ETP) extending back to the last ice age most often show low glacial δ15N, then a deglacial δ15N maximum, followed by a gradual decline to a late Holocene δ15N ... -
The Nitrogen Isotopic Composition of Tissue and Shell-Bound Organic Matter of Planktic Foraminifera in Southern Ocean Surface Waters
Smart, Sandi M.; Fawcett, Sarah E.; Ren, Haojia; Schiebel, Ralf; Tompkins, Emily M.; Martínez-García, Alfredo; Stirnimann, Luca; Roychoudhury, Alakendra; Haug, Gerald H.; Sigman, Daniel M. (Geochemistry, Geophysics, Geosystems, 2020)We present the first nitrogen isotope (δ15N) measurements of planktic foraminifera, paleoceanographically important zooplankton, from the nutrient-rich waters of the modern Southern Ocean. Foraminifera were collected from ...
