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 ... -
Intratest Variations in Trace Element Composition of Amphistegina lessonii Using Femtosecond‐Laser Ablation‐ICP‐Mass Spectrometry: A Field Study From Akajima, Okinawa Prefecture, Japan
Khanolkar, Sonal; Schiebel, Ralf; Singh, Asmita; Saraswati, Pratul Kumar; Jochum, Klaus Peter; Weis, Ulrike; Stoll, Brigitte; Haug, Gerald H. (Geochemistry, Geophysics, Geosystems, 2021-03-09)Amphistegina are common larger benthic foraminifer in coral reefs, with a nearly circumtropical distribution, and are major contributors to the CaCO3 budget of shallow marine environments. The family Amphisteginidae is ... -
Nano-Powdered Calcium Carbonate Reference Materials: Significant Progress for Microanalysis?
Jochum, Klaus Peter; Garbe-Schönberg, Dieter; Veter, Marina; Stoll, Brigitte; Weis, Ulrike; Weber, Michael; Lugli, Federico; Jentzen, Anna; Schiebel, Ralf; Wassenburg, Jasper A.; Jacob, Dorrit E.; Haug, Gerald H. (Geostandards and Geoanalytical Research, 2019)Homogeneity, mass fractions of about forty trace elements and Sr isotope composition of Ca carbonate reference materials (RMs) between original and nano-powdered pellets are compared. Our results using nanosecond and ... -
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 ...
