title: Cell growth and Particulate Organic Carbon / Nitrogen content of Phaeocystis antarctica after exposure to different Fe and Mn availabilities at the end of the experiment

description: Cell counts and POC/PON content of P.antartica for the 4 different treatments were determined at the beginning and at the end of the experiment. The cell density and size were determined using a Beckman MultisizerTM 3 Coulter Counter® with a 100 μm aperture. For the POC/PON, 250 mL of water were filtered onto pre-combusted glass-fiber filters (15h, 500 ̊C, GF/F, ~0.6 μm, 25 mm, Whatman, Wisconsin, USA) and stored at -20°C in pre-combusted glass petri dishes. Prior to analysis with an Euro Elemental Analyzer 3000 CHNS-O (HEKAtech GmbH), the filters were dried for &gt; 12h at 60 °C and then acidified with 200 μL of 0.2N HCL to remove inorganic carbon and dried a second time. Contents of POC and PON were corrected for blank measurements and normalized to filtered volume and cell densities to yield cellular quotas.

title: Cenozoic sea-level relative to modern from deep-sea geochemical and continental margin records

description: We use published Pacific benthic foraminiferal oxygen isotope data and Mg/Ca records to derive a Cenozoic (66 Ma) global mean sea level (GMSL) estimate. This paper is novel in providing the first Pacific benthic foraminiferal oxygen isotopic splice for the entire Cenozoic, a detailed (Myr scale) sea-level record for the last 48 Ma based on the benthic foraminiferal oxygen isotopic and Mg/Ca approach (Mg/Ca records older than 48 Ma are uncertain). We use the 2012 Geological Time Scale (GTS), a 2-Myr smoothed paleotemperatures (Cramer et al., 2011) who used a low-pass filter that passes &gt;80% of the amplitude for frequencies &lt;0.5/Myr (wavelength &gt;2 Myr), ramping down to &lt;20% of the amplitude for frequencies &gt;1.25/Myr (wavelength &lt;0.8 Myr). We used equation 7b Cramer et al. (2011) and a simplified paleotemperature equation for benthic foraminifera T = 16.1– 4.76 [δ18Obenthic – (δ18Oseawater – 0.27)] to solve for oxygen isotopic changes of seawater. We assume that shorter term (&lt;2 Myr) temperature changes comprise ~20% of the oxygen isotopic changes of seawater changes. The resultant oxygen isotopic changes of seawater estimate was scaled to GMSL changes using a revised seawater oxygen isotopes to sea-level calibration of 0.13‰/10 m of Winnick and Caves (2015). Because of temperature effects notable during peak Pleistocene interglacials, we iteratively fit the last interglacial cycle to known sea level during MIS5e and applied these temperatures (1.8°C) to major Middle to Late Pleistocene peak interglacials, tapering the temperature from the long term estimates for the peak interglacials using a Gaussian filter. We applied an empirically correction for carbonate ion change across the Eocene-Oligocene transition, to remove an apparent warming effect of ~1.5°C; we applied their empirical correction to the sea-level curve, reducing the amplitude by 28 meters from 34.17 to 34.30 Ma.

title: (Table S1) Benthic foraminifera at Ancora, Millville and Bass River drill sites

description: We describe seven Paleocene to lowermost Eocene sequences in core holes at Island Beach, Bass River, Ancora, Millville, and Sea Girt, NJ (Ocean Drilling Program Leg 150X, 174AX) and analyze benthic foraminiferal assemblages to assess paleodepth changes within sequences. These sequences are referred to as Pa0, Pa1a, Pa1b, Pa2a, Pa2b, Pa3a, and Pa3b. Paleocene sequence boundaries are identified by unconformities and variations in benthic foraminiferal biofacies. We used Q-mode factor analysis and paleoslope modeling to identify three distinct middle-outer neritic benthic foraminiferal assemblages and their associated water depths. Paleodepths during the early Paleocene and deposition of Pa0, Pa1a, and Pa2b were ~80 m with ~20 m changes across sequence boundaries. A long-term shallowing occurred through the late Paleocene where paleodepths were ~50-70 m in Pa3a. This trend drastically changes in the earliest Eocene where the paleodepths of sequence Pa3b were ~120-150 m. New Jersey Paleocene sequence boundaries correlate with those in other regions and with d18O increases in the deep sea, suggesting Paleocene eustatic lowerings were associated with ice-growth events.

title: Photophysiological responses of Southern Ocean phytoplankton to changes in CO2 concentrations: Short-term versus acclimation effects

description: The present study examines how different pCO2 acclimations affect the CO2- and light-dependence of photophysiological processes and O2 fluxes in four Southern Ocean (SO) key phytoplankton species. We grew Chaetoceros debilis (Cleve), Pseudo-nitzschia subcurvata (Hasle), Fragilariopsis kerguelensis (O'Meara) and Phaeocystis antarctica (Karsten) under low (160 µatm) and high (1000 ?atm) pCO2. The CO2- and light-dependence of fluorescence parameters of photosystem II (PSII) were determined by means of a fluorescence induction relaxation system (FIRe). In all tested species, nonphotochemical quenching (NPQ) is the primary photoprotection strategy in response to short-term exposure to high light or low CO2 concentrations. In C. debilis and P. subcurvata, PSII connectivity (p) and functional absorption cross-sections of PSII in ambient light (sigma PSII') also contributed to photoprotection while changes in re-oxidation times of Qa acceptor (tQa) were more significant in F. kerguelensis. The latter was also the only species being responsive to high acclimation pCO2, as these cells had enhanced relative electron transport rates (rETRs) and sigma PSII' while tQa and p were reduced under short-term exposure to high irradiance. Low CO2-acclimated cells of F. kerguelensis and all pCO2 acclimations of C. debilis and P. subcurvata showed dynamic photoinhibition with increasing irradiance. To test for the role and presence of the Mehler reaction in C. debilis and P. subcurvata, the light-dependence of O2 fluxes was estimated using membrane inlet mass spectrometry (MIMS). Our results show that the Mehler reaction is absent in both species under the tested conditions. We also observed that dark respiration was strongly reduced under high pCO2 in C. debilis while it remained unaltered in P. subcurvata. Our study revealed species-specific differences in the photophysiological responses to pCO2, both on the acclimation as well as the short-term level.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne et al, 2014) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation is 2014-07-01.

title: (Table 1) Gas tie points used to correlate the ice cores NGRIP and EDML

description: Water isotope records from the EPICA Dronning Maud Land (EDML) and the NorthGRIP ice cores have revealed a one to one coupling between Antarctic Isotope Maxima (AIM) and Greenland Dansgaard-Oeschger (DO) events back to 50 kyr. In order to explore if this north–south coupling is persistent over Marine Isotopic Stage 5 (MIS 5), a common timescale must first be constructed.Here, we present new records of d18O of O2 (d18Oatm) and methane (CH4) measured in the air trapped in ice from the EDML (68–147 kyr) and NorthGRIP (70–123 kyr) ice cores. We demonstrate that, through the period of interest, CH4 records alone are not sufficient to construct a common gas timescale between the two cores. Millennial-scale variations of d18Oatm are evidenced over MIS 5 both on the Antarctic and Greenland ice cores and are coupled to CH4 profiles to synchronise the NorthGRIP and EDML records. They are shown to be a precious tool for ice core synchronisation.With this new dating strategy, we produce the first continuous and accurate sequence of the north–south climatic dynamics on a common ice timescale for the last glacial inception and the first DO events of MIS 5, reducing relative dating uncertainties to an accuracy of a few centuries at the onset of DO events 24 to 20. This EDML-NorthGRIP synchronisation provides new firm evidence that the bipolar seesaw is a pervasive pattern from the beginning of the glacial period. The relationship between Antarctic warming amplitudes and their concurrent Greenland stadial duration highlights the particularity of DO event 21 and its Antarctic counterpart. Our results suggest a smaller Southern Ocean warming rate for this long DO event compared to DO events of MIS 3.

Note that synchronisation uncertainties are minimal for DO events 19, 20 and 21 thanks to the use of d15N.
