title: Drake passage benthic foraminiferal abundance during the last deglaciation

description: The Antarctic Cold Reversal (ACR; 14.7 to 13 ka) phase of the last deglaciation saw a pause in the rise of atmospheric pCO2 and Antarctic temperature, contrasted with warming in the North. Mechanisms associated with interhemispheric heat transfer have been proposed to explain features of this event, but the response of marine biota and the carbon cycle are debated. The Southern Ocean is a key site of deep-water exchange with the atmosphere, hence deglacial changes in nutrient cycling, circulation, and productivity in this region may have global impact. Here we present a new perspective on the sequence of events in the deglacial Southern Ocean, that includes multi-faunal benthic assemblage (foraminifera and cold-water corals) and geochemical data (Ba/Ca, 14C, δ11B) from the Drake Passage. Our records feature anomalies during peak ACR conditions indicative of circulation, biogeochemistry, and regional ecosystem perturbations. Within this cold episode, peak abundances of thick-walled benthic foraminifera and cold-water corals are observed at shallow depths in the sub-Antarctic (~300 m), while coral populations at greater depths and further south diminished. Geochemical data indicate that habitat shifts were associated with enhanced primary productivity in the sub-Antarctic, a more stratified water column, and poorly oxygenated bottom water. These results are consistent with northward migration of primary production in response to Antarctic cooling and widespread biotic turnover across the Southern Ocean. We suggest that expanding sea ice, suppressed ventilation, and shifting centres of upwelling drove changes in planktic and benthic ecology, and were collectively instrumental in halting CO2 rise in the mid-deglaciation.

title: Planktonic foraminiferal assemblages in sediment core KC01B

description: Planktonic foraminiferal assemblages were studied at high-resolution in core KC01B from the Ionian Sea. Quantitative analysis allowed us to distinguish the main climatic features and associated paleoceanographic changes, that occurred between Marine Isotopic Stages (MIS) 13 and 9 (~500-300 ka).MIS 12 and MIS 10 are characterized by relatively temperate conditions and an oligotrophic oceanographic regime in the early part and by colder conditions and nutrient supply in the sub-surface water masses in the upper part. During these intervals, small but distinct peaks of Neogloboquadrina pachyderma sinistral (sin) are detected at times of extremely negative values of the planktonic foraminifera paleoclimatic curve. Their co-occurrence with similar episodes in the Atlantic suggests that the climate in the Central Mediterranean was associated with north-Atlantic millennial-scale climate instability. MIS 11 and MIS 9 are dominated by surficial warm-water taxa. The climate optimum is reached in the middle part of each of these stages, as denoted by the presence of Globigerinoides sacculifer, and persists for approximately 20 and 6 ka during MIS 11 and MIS 9 respectively. This warming is not constant but is characterized by three distinct intervals with elevated winter temperatures and/or weak winter mixing.Distribution of Globigerina bulloides, Turborotalita quinqueloba and N. pachyderma dextral (dex) indicates that significant environmental changes occur across the transitions from glacial to interglacial MIS 12/MIS 11 (Termination V) and MIS 10/MIS 9 (Termination IV).The studied record documents a close linkage between Mediterranean climate evolution and higher- and lower-latitude climate change throughout MIS 13-9.

title: Mineralogical composition from different surface sediment samples of Lake Towuti, Indonesia

description: For granulometric, geochemical and mineralogical analyses, approximately 25 ml of each surface sample was frozen for 24 hours and subsequently lyophilized using a Christ BETA 1-8 LDplus (Martin Christ Gefriertrocknungsanlagen GmbH, Osterode am Harz, Germany). The freeze-dried samples were homogenized and split into two aliquots. The other aliquot of the freeze-dried surface samples was ground to &lt;63 µm with a Planetary Mill Pulverisette 5 (FRITSCH GmbH, Idar-Oberstein, Germany) and used for mineralogical and geochemical analyses. The bulk mineralogy was determined on powder samples using an X-ray diffractometer (D8 Discover; Bruker, Billerica, MA, USA) with a Cu X-ray tube (λ = 1.5418 Å, 40 kV, 30 mA) and a LYNXE XE detector (opening angle = 2.9464°). The spectrum from 3° to 100° 2-theta was measured in 0.02° steps at 1 second exposure time. Mineral identification was carried out using the software packages SEARCH (Stoe and Cie GmbH, Darmstadt, Germany) and Match! (Crystal Impact 2014, Bonn, Germany), supported by the data base pdf2 (ICDD 2003, Newton Square, PA, USA). The concentration of the minerals was evaluated using the program TOPAS Rietveld (Coelho Software, Brisbane, Australia), which yields a standard deviation of analyzed minerals varying from +/- 2 % (for quartz) to +/- 5 to 10 % (for feldspars and clay minerals; Środoń et al., 2001; Vogt et al., 2002). For the clay mineral group illite the error range can be even higher (Scott 1983). Given these uncertainties, a detection limit of 5 % is considered in the discussion of the mineralogical composition of the surface sediments.

description: Two Pacific Ocean manganese nodules, one from the ocean basin and one from a sea-mount, were examined in transmission electron microscopes at 100 and 650 kV. Of the many specimens examined, ten electron diffraction crystal spot patterns were identified. Sodium birnessite was observed six times and todorokite, Giavanoli's synthetic birnessite, hydrohausmanite and -Fe2O3 one time each. Ferric hydroxide was synthesized in the laboratory and shown to be the same as the primary iron mineral observed in the manganese nodules. The ferric hydroxide had a particle size range from 30 to around 450. Manganese oxide particles were frequently embedded in a mass of smaller ferric hydroxide particles.

description: Data were collected using GNSS survey methods, with a differential GPS operating in Real Time Kinematic (RTK) mode. Data from prior to 2013 were typically collected with a Magellan ProMark 3 traditional RKT-DGPS system (i.e. local base station and rover), with the base station sited on survey control markers installed in 1996, with survey control coordinates referenced to NAD83(CORS91). Starting in 2013 survey data were typically collected with an AshTech ProMark 200 RTK-DGPS system connected to the Washington State Reference Network. Survey data collected between January and November 2013 are referenced to NAD83(CORS96), and after November 2013 to NAD83(2011). Vertical data for surveys in 2012 and 2013 are referenced to NAVD88, presumably using Geoid96 (the survey control documentation does not specific a geoid). For all subsequent surveys the vertical data are referenced to NAVD88(Geoid09). No conversion were applied to these data to account for variations in horizontal or vertical coordinate system adjustments through time, but an error analysis suggests a standard deviation for the elevation data of between 0.03 and 0.05 m across the entire sampling period (2011-2018). All survey data were collected with the GNSS system mounted on a 2.05 m rover pole, held level as a transect line was traced in a cross-shore orientation on the beach. The associated text files include the horizontal (HRMS) and vertical (VRMS) root-mean-square errors estimated by the GNSS system, as well as the RTK-DGPS status reported by the GNSS system at the time each point was collected. Times are referenced to local Pacific time (either PST or PDT).
description: Portions of these data have been published previously, including in Gelfenbaum et al. 2015.
