Boron isotopes in foraminifera from sediment cores and 2 pH scenarios Dataset Description: <p>Isotope data for delta-11B&nbsp;from late Paleocene-early Eocene planktonic foraminifera. The taxa analyzed include Morozovella velascoensis, Acarinina soldadoensis, and Subbotinae.</p>
<p>These data were published in&nbsp;Penman, D. E., B. Hönisch, R. E. Zeebe, E. Thomas, and J. C. Zachos (2014), Rapid and sustained surface ocean acidification during the Paleocene-Eocene Thermal Maximum, Paleoceanography, 29, 357-369, doi:10.1002/2014PA002621.</p> Methods and Sampling: <p>Samples were collected during Ocean Drilling Program (ODP) Leg 198, three holes were drilled at Site 1209 (Shatsky Rise, N. Pacific 32°39.1081'N, 158°30.3564'E) at a water depth of 2387 m [Bralower et al., 2002], equivalent to a paleodepth during the PETM of ~ 1900 m [Takeda and Kaiho, 2007].&nbsp;</p>
<p>Sediment samples, collected at 1-3 cm resolution across a 2m interval spanning the carbon isotope excursion (CIE), were washed and sieved, and specimens of the mixed-layer dwelling planktic species <em>Morozovella velascoensis</em> and <em>Acarinina soldadoensis</em> were picked from the 250-300 and 300-425 µm size fraction. On the basis of shell size-d13C relations, these species likely harbored photosynthetic algal symbionts and were thus restricted to the photic zone of the surface ocean [D’Hondt et al., 1994]. Additionally, specimens of the smooth-walled, thermocline-dwelling genus <em>Subbotina</em> were picked from the 250-300 µm size fraction. Isotopic depth ranking suggests that this taxon was nonsymbiotic and occupied the thermocline [Berggren and Norris, 1997]. Boron isotope analyses at Site 1209 were restricted to <em>M. velascoensis</em> and complemented by low-resolution d11B analyses of the same taxon from Sites 1263 (Walvis Ridge, Southeast Atlantic, 28°31.98'S, 02°46.77'E, 2717 m depth; paleodepth ~1500 m; [Zachos et al., 2004]) and 865 (Allison Guyot, Equatorial Pacific, 18°26.41'N, 179°22.24'W, 1518 m depth; paleodepth ~ 1400 m; [Bralower et al., 1995]) to evaluate whether the Site 1209 record is representative of a global signal or compromised by local or preservational effects.</p>
<p>Trace element data are generated from a Finnegan Element XR Inductively Coupled Plasma Mass Spectrometer monitoring masses 11B, 24Mg, 43Ca, 55Mn (to detect contamination from Fe, Mn oxides), and 238U. Inter- and intra- run variability will be assessed utilizing both a solid foraminiferal standard (mixture of crushed foraminifera that will be cleaned as samples) and a liquid consistency standard of similar composition as the dissolved foraminifera. The solid foraminiferal consistency standard composed of crushed and homogenized Globigerinoides sacculifer from core top KNR 110 2-58 STN40-2 (without final sac; B/Ca = 92 +- 8 µmol/mol). 13C and 18O data from the dual Inlet gas source mass spectrometer systems at the University of California Santa Cruz – Stable Isotope Laboratory are measured against reference gases which have been calibrated relative to international reference materials (NBS-19, NBS-18) obtained from the National Institute of Standards and Technology (NIST) and the International Atomic Energy Agency (IAEA) to ensure accurate measurement and reporting of isotope ratios for the selected samples. These same international standards are analyzed on a daily basis, typically at the start and finish of each analytical round. In addition, internal laboratory standards are analyzed at a much greater frequency during each analytical round to assess data quality during the course of each analytical round. The analytical error on standards measured during the course of analyses conducted for this project will be monitored and reported for each analytical round.</p>
<p>Boron isotope data will be generated from a Thermo TRITON Thermal Ionization Mass Spectrometer at LDEO and from Thermo NEPTUNE multi-collector inductively coupled mass spectrometers at UC Santa Cruz and LDEO. Sample preparation for all analyses will be done in a boron filtered ultraclean environment, to avoid laboratory contamination. The international boric acid standard NBS 951 obtained from NIST is routinely measured on the TIMS with each sample wheel and shows no long-term drift for this method. MC-ICP-MS analyses are subject to daily drift and standard bracketing with NBS 951 will be applied to monitor and correct for drift. Additional routine in-house standards include NBS 951 precipitated in a CaCO3 matrix and seawater. For MC-ICP-MS analyses a natural carbonate from the Geological Survey of Japan (GSJ) geochemical reference sample collection will be used as an additional standard to monitor B purification consistency. Despite standardization to the same boric acid standard, absolute 11B values by TIMS are often higher than those measured by MC-ICP-MS. However, Fig. 4 and an international laboratory intercomparison study (Foster, Hönisch et al., in prep.) confirm that the TPI 7220824 relative difference in foraminiferal and coral 11B over the same pH-difference (determined from laboratory cultures and glacial/interglacial sediment samples) is the same for both methods, thus allowing for sound comparison of data from both methods, as long as method-specific calibrations are applied. 11B of the foraminifer species used in this study can thus be calibrated with Paleocene (pre-CIE) samples using both techniques, and the same slope and inflection point of the delta-11B/pH&nbsp;relationship (Fig. 4) will then be applied to estimate the pH-change during and after the PETM relative to the Paleocene baseline.</p>

International Ocean Discovery Program
The International Ocean Discovery Program (IODP) is an international marine research collaboration that explores Earth's history and dynamics using ocean-going research platforms to recover data recorded in seafloor sediments and rocks and to monitor subseafloor environments. IODP depends on facilities funded by three platform providers with financial contributions from five additional partner agencies. Together, these entities represent 26 nations whose scientists are selected to staff IODP research expeditions conducted throughout the world's oceans.
IODP expeditions are developed from hypothesis-driven science proposals aligned with the program's science plan Illuminating Earth's Past, Present, and Future. The science plan identifies 14 challenge questions in the four areas of climate change, deep life, planetary dynamics, and geohazards.
IODP's three platform providers include:
The U.S. National Science Foundation (NSF)
Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT)
The European Consortium for Ocean Research Drilling (ECORD)
More information on IODP, including the Science Plan and Policies/Procedures, can be found on their website at http://www.iodp.org/program-documents.

Establishing The Magnitude Of Sea-Surface Acidification During The Paleocene-Eocene Thermal Maximum

Establishing The Magnitude Of Sea-Surface Acidification During The Paleocene-Eocene Thermal Maximum
<p><em>Extracted from the NSF award abstract:</em></p>
<p>At projected rates of anthropogenic carbon emissions, the pH of the surface ocean is expected to decline by 0.3 pH units by the end of this century, and 0.7 pH units by 2300. The only other time the ocean might have experienced a similar change in pH in the past is during the Paleocene-Eocene Thermal Maximum (PETM; 56 Mya) as a consequence of a massive carbon release, which also warmed the planet. The mass of carbon released is estimated to have been as large as that projected for the future but over thousands of years rather than centuries, thus allowing for greater buffering of the saturation state of the surface ocean. Nonetheless, planktonic calcifiers and coral reefs both experienced significant reductions in diversity, likely in response to a combination of factors, including pH and carbonate saturation state. Efforts to quantify changes in carbonate chemistry, however, have relied on indirect methods, that is with numerical models of the carbon cycle constrained by observations of changes in ocean carbonate chemistry such as carbon isotopes and the distribution of carbonate sediments. In computing the mass and rate of carbon release, the models also simulate changes in ocean pH and saturation state. While the range of model estimates continues to narrow, testing has been limited by the lack of more direct information on ocean carbonate chemistry, specifically changes in the pH and/or carbonate ion concentration.</p>
<p>To address this deficiency, a team of scientists from the University of California at Santa Cruz, the Lamont-Doherty Earth Observatory of Columbia University, and the University of Hawaii are conducting a 3-year study to quantify changes in the sea-surface carbonate chemistry during the PETM. The project will focus on the application of two boron-based proxies, B/Ca and B isotopes as recorded in planktonic foraminifera, to quantify pH and possibly carbonate ion concentration. The team will develop detailed proxy records for a number of globally distributed locations, with the goal of establishing regional anomalies in surface ocean carbonate chemistry relative to longer-term trends. The data will be interpreted with numerical models utilizing information from laboratory-based calibration studies of modern foraminifera, and compared with plankton assemblage records. The results will also provide an independent means of testing model simulations of the rate and duration of carbon release, and ultimately the rise in atmospheric CO2.</p>

Despite standardization to the same boric acid standard, absolute 11B values by TIMS are often higher than those measured by MC-ICP-MS. However, Fig. 4 and an international laboratory intercomparison study (Foster, Hönisch et al., in prep.) confirm that the TPI 7220824 relative difference in foraminiferal and coral 11B over the same pH-difference (determined from laboratory cultures and glacial/interglacial sediment samples) is the same for both methods, thus allowing for sound comparison of data from both methods, as long as method-specific calibrations are applied. 11B of the foraminifer species used in this study can thus be calibrated with Paleocene (pre-CIE) samples using both techniques, and the same slope and inflection point of the delta-11B/pH&nbsp;relationship (Fig. 4) will then be applied to estimate the pH-change during and after the PETM relative to the Paleocene baseline.</p>
