title: (Table S6) Nd isotopes of ODP Site 172-1061 and 172-1063 core top samples

description: Neodymium isotopes were analysed using the Nu Plasma HR multi-collector mass spectrometer (MC-ICPMS) at the University of Cambridge, using bracketing of JNdi-1 for standard correction. 146Nd/144Nd was normalised to 0.7219. Reported 143Nd/144Nd are for 30 ratios and the error reported is the internal error of the analysis (2 sigma). The epsilon-Nd is reported with respective external errors (2 sigma) for that particular session, unless the internal error was larger than the external, in which case the combined internal and external error (2 sigma) is reported.

Sr ratios were measured in a static mode and using time resolved analysis (TRA) on a Nu MC-ICPMS and 87Sr/86Sr ratios were corrected for mass-bias using an exponential law and 86Sr/88Sr=0.1194. The long-term average value of the TRA-measured 87Sr/86Sr of NBS 987 is 0.710246 (+/-0.000030, 2 sigma). All reported 143Nd/144Nd ratios were corrected for mass fractionation using 146Nd/144Nd=0.7219. International standard JNdi-1 was analyzed between every 5-6 unknown samples and the average of these standard runs were compared to a long term TIMS JNdi-1 value of 0.512103 to determine a correction factor for each of the samples analyzed on that day. Long term external reproducibility of JNdi-1 analyses on the Nu is 0.000014 (0.3 epsilon-Nd units).

title: Nd and Sm isotopic record from fossil fish teeth recovered from ODP Site 177-1090

description: Neodymium (Nd) isotopes were measured on 181 samples of fossil fish teeth recovered from Oligocene to Miocene sections at Ocean Drilling Program Site 1090 (3700 m water depth) on Agulhas Ridge in the Atlantic sector of the Southern Ocean. A long-term decreasing trend toward less radiogenic Nd isotope compositions dominates the record. This trend is interrupted by shifts toward more radiogenic compositions near the early/late Oligocene boundary and the Oligocene/Miocene boundary. Overall, epsilon-Nd values at Agulhas Ridge are more radiogenic than at other Atlantic locations, and are similar to those at Indian Ocean locations. The pattern of variability is remarkably similar to Nd isotope results from Walvis Ridge (South Atlantic) and Ninetyeast Ridge (Indian Ocean). In contrast, Agulhas Ridge and Maud Rise Nd isotope records do not show similar patterns over this interval. Results from this study indicate that deep water in the Atlantic flowed predominantly from north to south during the Oligocene and Miocene, and that export of Northern Component Water (NCW) to the Southern Ocean increased in the late Oligocene. There is also evidence for efficient exchange of deep waters between the Atlantic sector of the Southern Ocean and the Indian Ocean, although the direction of deep water flow is not entirely clear from these data. The shifts to more radiogenic Nd isotopic compositions most likely represent increases in the flux of Pacific waters through Drake Passage, and the timing of these events reflect development of a mature Antarctic Circumpolar Current (ACC). The relative timing of increased NCW export and ACC maturation support hypotheses that link deep water formation in the North Atlantic to the opening of Drake Passage.

title: Bathymetry measured near Pine Island Glacier during POLARSTERN cruise PS104, link to GeoTIFF

description: Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. Its ice loss has substantially increased over the last 25 years through thinning, acceleration and grounding line retreat. However, the calving line positions of the stabilising ice shelf did not show any trend within the observational record (last 70 years) until calving in 2015 led to unprecedented retreat and changed the alignment of the calving front. Bathymetric surveying revealed a ridge below the former ice shelf and two shallower highs to the north. Satellite imagery shows that ice contact on the ridge was likely lost in 2006 but was followed by intermittent contact resulting in back stress fluctuations on the ice shelf. Continuing ice-shelf flow also led to occasional ice-shelf contact with the northern bathymetric highs, which initiated rift formation that led to calving. The observations show that bathymetry is an important factor in initiating calving events.
description: The bathymetric data was acquired with the hull-mounted Hydrosweep DS3 system during expedition PS104 of RV Polarstern in 2017. The data was gridded at 25 m resolution in Fledermaus and exported as GeoTiff.

description: Abstract: The Intertropical Convergence Zone (ITCZ) encompasses the heaviest rain belt on the Earth. Few direct long-term records, especially in the Pacific, limit our understanding of long-term natural variability for predicting future ITCZ migration. Here we present a tropical precipitation record from the Southern Hemisphere covering the past 282,000 years, inferred from a marine sedimentary sequence collected off the eastern coast of Papua New Guinea. Unlike the precession paradigm expressed in its East Asian counterpart, our record shows that the western Pacific ITCZ migration was influenced by combined precession and obliquity changes. The obliquity forcing could be primarily delivered by a cross-hemispherical thermal/pressure contrast, resulting from the asymmetric continental configuration between Asia and Australia in a coupled East Asian-Australian circulation system. Our finding suggests that the obliquity forcing may play a more important role in global hydroclimate cycles than previously thought.

title: Mediterranean-wide pollen-inferred Holocene vegetation classification

description: Fossil and modern pollen data sets are used to infer Holocene vegetation change for 6 case study regions across the Mediterranean and at a pan-Mediterranean scale (described by Fyfe et al., 2018 and Woodbridge et al. 2018). The approach to understanding land cover change employs hierarchical cluster analysis and community classification to derive 16 vegetation clusters from multiple pollen sequences. The results also include reconstructions for a selection of pollen indicator groups e.g. an Anthropogenic Pollen Index (API) and an index for cultivated trees (Olea, Juglans, Castanea and Vitis) (Mercuri et al., 2013). Major patterns in the data sets are summarized by non-metric Multi Dimensional Scaling (nMDS) and Simpson's diversity index. Most of the pollen data derive from the European Pollen Database (Fossil: Leydet, 2007-2018 and modern: Davis et al., 2013), supported by chronologies developed by Giesecke et al (2014) supplemented by additional pollen sites for individual case study regions.

title: Glacier Surface Velocities and Outlet Areas from 2014-2018 on James Ross Island, Northern Antarctic Peninsula

description: These data report the spatial and temporal variability of glacier surface velocities and the area of their outlets throughout James Ross Island at the northern Antarctic Peninsula. Manually digitized calving front positions from panchromatic Landsat-8 data at 15 m resolution were used to calculate outlet areas by using a common-box approach. The common-box outlines were digitized by using the relative steep apparent coastlines of the current glacier bay and the visible brim of the cliff in a Landsat-8 scene from 2017-02-20, as well as side boundaries from Davies et al. (2012). Velocity estimates are retrieved from intensity feature tracking of TerraSAR-X and TanDEM-X scenes between 2014 and 2018 and clipped to the outlet area of the temporally nearest data of the area data set. More details about the processing can be found in Lippl et al. (2019).The naming convention is:Areas: Area_*GlimsID_*LandsatSceneDate (Format: shapefile)Reference Polygon for Common-box approach: Area_*GlimsID_ReferencePolygon (Format: shapefile)Velocities: Velocity_*GlimsID_*LandsatScenceDate_dis_mag+*StartDate--*EndDate_crop.tif_focalStd21_crop.tif (Format: GeoTIFF, Unit: Meter per day)(Parameter after * are variable. StartDate and EndDate are the dates of the used TerraSAR-X and TanDEM-X scenes in intensity feature tracking. When no GlimsID was available for the glacier, the ID used by Davies et al. (2012) or names used in the submitted paper from Lippl et al. (2019) were applied.)

title: Distribution maps of endemic Caspian Sea mollusks in hotspot and non-hotspot areas

description: The Caspian Sea is renowned for its endemic mollusk biodiversity. However, over the past decades, increasing anthropogenic pressures have caused decreases in abundances and even extinction of species. Both key pressures and endemic taxa are distributed spatially unevenly across the Caspian Sea, suggesting that ecologically different taxa such as gastropods and bivalves are also affected differentially. In addition, hotspot and non-hotspot areas for these taxa might differ quantitatively in pressure scores and qualitatively in key individual anthropogenic pressures. To test this working hypothesis, hotspot areas for endemic bivalve and gastropod species were identified using stacked species ranges. Cumulative and individual pressure scores were estimated for hotspot and non-hotspot areas of bivalves and gastropods. Differences in cumulative and individual pressure scores were tested for significance using non-parametric MANOVA and Wilcoxon rank sum tests, respectively. We identified various mollusk biodiversity hotspots across locations and depths, which are differentially affected both in terms of cumulative pressure scores and in the composition of the contributing individual pressures. Similarly, hotspot and non-hotspot areas for both bivalves and gastropods are differentially affected by anthropogenic pressures. By defining endemic hotspot areas and the respective anthropogenic pressures, this study provides an important baseline for mollusk-specific conservation strategies.

title: The Arctic Ocean volume, heat and fresh water transports time series from October 2004 to May 2010

description: This dataset provides 68 months time series of the Arctic ocean heat and FW transports from October 2004 to May 2010. They are estimated based on large amount of mooring data (around 1,000 moored instrument records) in the Arctic main gateways (Davis Strait, Fram Strait, Barents Sea Opening and Bering Strait) using box inverse model method as described in Tsubouchi et al. (2018).Thus, this dataset quantifies inter-annual variability of ocean volume, heat and FW transports. In the heat transport, we find maxima (169 TW) in 2004-2005 and minima (136 TW) in 2007-2008. The size of inter-annual variabilities accounts to 11% in total ocean transport. In the FW transport, we find maxima (127 mSv) in 2005-2006 and minima (67 mSv) in 2007-2008. The size of inter-annual variability accounts to 30% in total ocean FW transport. The quantified ocean transports and associated water mass transformation served as a bench mark dataset to validate various general ocean circulation models.
