Basic geochemical data of DSDP Site 80-550, from the latest Paleocene to the late Early Eocene, including PETM, ETM2 and ETM3

Simon D'haenens, André Bornemann, Philippe Claeys, Ursula Röhl, Etienne Steurbaut & Robert P Speijer
Calculated ages relative to the onset of the PETM (based on Westerhold et al., 2009, EPSL and our age model) are shown as are linear sedimentation rates (LSRs) and mass accumulation rates (MARs).

Stress-tolerant corals of Florida Bay are vulnerable to ocean acidification

Remy Okazaki, Peter K Swart & Chris Langdon
In situ calcification measurements tested the hypothesis that corals from environments (Florida Bay, USA) that naturally experience large swings in pCO2 and pH will be tolerant or less sensitive to ocean acidification than species from laboratory experiments with less variable carbonate chemistry. The pCO2 in Florida Bay varies from summer to winter by several hundred ppm roughly comparable to the increase predicted by the end of the century. Rates of net photosynthesis and calcification of...

(Table 1) Age determination on various planktonic foraminifera from Ontong Java Plateau core top sediments

Stephen Barker, Wallace S Broecker, Elizabeth Clark & Irka Hajdas
Shells of coexisting species of planktonic foraminifera from the Ontong Java Plateau reveal radiocarbon age offsets of up to 2200 years. Similar offsets are found between fragments and whole shells of single species. Steady state modelling of dissolution and bioturbation within the sedimentary mixed layer predicts age differences of up to several kiloyears due to the interplay between differential dissolution and fragmentation of foraminifer shells and bioturbation. The observation that fragile foraminiferal shells are systematically...

(Table 1) Nd isotope ratios of ODP Leg 208 samples

Deborah J Thomas & Rachael K Via
We present new Nd isotope records from Walvis Ridge Ocean Drilling Program (ODP) sites 1262–1264 (southeastern Atlantic) spanning the past 24 Ma to investigate the Neogene evolution of Atlantic thermohaline circulation. The new data indicate that deepwater epsilon-Nd(t) values from ODP Site 1262 decrease from -11.0 at 10.6 Ma to -12.5 by 7.3 Ma. This decrease parallels the Nd isotope trends contained in Fe-Mn crust records from the northwestern Atlantic; however, the shift at ODP...

Response of benthic foraminifera to ocean acidification in their natural sediment environment: a long-term culturing experiment

Kristin Haynert, Joachim Schönfeld, Ralf Schiebel, Brent Wilson & Jörn Thomsen
Calcifying foraminifera are expected to be endangered by ocean acidification; however, the response of a complete community kept in natural sediment and over multiple generations under controlled laboratory conditions has not been constrained to date. During 6 months of incubation, foraminiferal assemblages were kept and treated in natural sediment with pCO2-enriched seawater of 430, 907, 1865 and 3247 µatm pCO2. The fauna was dominated by Ammonia aomoriensis and Elphidium species, whereas agglutinated species were rare....

Calcium and sodium concentrations of the Talos Dome ice core, Antarctica

Simon Schüpbach, Urs Federer, Patrik R Kaufmann, Samuel Albani, Carlo Barbante, Thomas F Stocker & Hubertus Fischer
In this study we report on new non-sea salt calcium (nssCa2+, mineral dust proxy) and sea salt sodium (ssNa+, sea ice proxy) records along the East Antarctic Talos Dome deep ice core in centennial resolution reaching back 150 thousand years (ka) before present. During glacial conditions nssCa2+ fluxes in Talos Dome are strongly related to temperature as has been observed before in other deep Antarctic ice core records, and has been associated with synchronous changes...
