title: Stable carbon and oxygen isotope ratios of foraminifera from DSDP Site 94-606

description: Stable-isotope analysis of two species of benthic foraminifers (Planulina wuellerstorfi and Globocassidulina subglobosa) and one planktonic species (Globigerina bulloides) from DSDP Site 606 reveals the evolution of late Pliocene climate change. No 'stepwise' increase is evident in the delta18O record at 3.2 Ma, but events of 18O-enrichment of increasing magnitude occurred at 3.1, 2.7, 2.6, and 2.4 Ma. The two youngest events are correlated with events indicating glaciation at northeast Atlantic DSDP Hole 552A (Shackleton et al., 1984, doi:10.1038/307620a0). The oldest delta18O spike, centered within the Mammoth Paleomagnetic Event, is the most prominent feature of results for the interval between 3 and 4 Ma. This isotope event is interpreted as evidence of 2°C bottom-water cooling combined with minor glaciation.Carbon-isotope results for P. wuellerstorfi indicate that Site 606 has been under the influence of North Atlantic Deep Water for most of the interval from 2 to 4 Ma. A significant change in 'vital effect' on G. subglobosa at 2.4 Ma is evident in the delta13C record. Specimens dating from that time become smaller and less abundant than older specimens, and have delta13C values lowered by as much as lâ. This effect could introduce a significant artifact into data sets where various species are 'corrected' to P. wuellerstorfi.

title: (Table 1) Datasets used in the South Sandwich arc bathymetric compilation

description: The South Sandwich Islands and associated seamounts constitute the volcanic arc of an active subduction system situated in the South Atlantic. We introduce a map of the bathymetry and geological setting of the South Sandwich Islands and the associated East Scotia Ridge back-arc spreading centre that consists of two sides: side 1, a regional overview of the volcanic arc, trench and back-arc, and side 2, detailed maps of the individual islands. Side 1 displays the bathymetry at scale 1:750 000 of the intra-oceanic, largely submarine South Sandwich arc, the back-arc system and other tectonic boundaries of the subduction system. Satellite images of the islands on side 2 are at scales of 1:50 000 and 1:25 000 with contours and main volcanological features indicated. These maps are the first detailed topological and bathymetric maps of the area. The islands are entirely volcanic in origin, and most have been volcanically or fumarolically active in historic times. Many of the islands are ice-covered, and the map forms a baseline for future glaciological changes caused by volcanic activities and climate change. The back-arc spreading centre consists of nine segments, most of which have rift-like morphologies.

title: (Table 967ARMCD) Color reflectance data sets of Hole 160-967A

description: We have developed revised postcruise composite depth sections over the ~100-m-long, Pliocene-Holocene sediment sequences at four paleoceanographic sites (Site 964: Ionian Basin; Sites 966 and 967: Eratosthenes Seamount; Site 969: Mediterranean Ridge), which are located in different tectonic and oceanographic settings and water depths in the Eastern Mediterranean Sea. These revised composite sections were constructed using correlation intervals of a few centimeters instead of the 1- to 10-m intervals used in the shipboard composite construction procedure. These revised composite depth sections now take into account differential stretching and squeezing within a core and correct depth differences between holes caused by coring artifact and tectonic disturbances that resulted in attenuated and incomplete sections. The revised composite depth sections were constructed by combining digitized color images of split cores, visual core descriptions from shipboard operations, and color reflectance measurements with a 2-cm sampling resolution. The detailed revised depth sequences not only enable us to correlate sapropels between holes, but also other lithofacies, such as pale nannofossil oozes, reddish oozes, dark clays, and ash layers. Depending on the location of the drill site, over 80 individual sapropels are recognized in the revised composite depth sections. During Leg 160, use of the advanced piston coring system on the JOIDES Resolution typically resulted in an average gap between cores of 1-2 m, with a maximum of 8 m. Gaps within cores, resulting from faulting, slumping, or mass flows, also averaged 1-2 m in length. These revised composite depth sections can be used as starting points for the development of highresolution time scales and paleoceanographic time series in the Mediterranean.

title: Pollen profile from sediment core Eich-Gimbsheimer Altrhein

description: Stratigraphy: 0-5.76 m light grey clay and silt (above sand), humous and less solid in the uppermost half meter.Devices: Hiller corer (0-0.96 m), Dachnowski corer (below 0.8 m)A proper interpretation of the pollen data has to consider that the site was originally a meander of the river Rhine which was cut off from the main stream and thus became an oxbow lake. Accordingly the profile should consist of fluvial sediment in its lower part and of lacustrine sediment further up. The distribution of the pollen grains of Picea and Abies throughout the profile parallels the expected change of sediment. Although both tree species have never grown in the area during the Holocene, but stayed restricted to the mountainous regions further south (e.g. the Black Forest), their pollen is found in rather large quantities in the lowermost samples of the profile, but is almost absent further up. As the two pollen types can easily swim the distinct decrease of their frequencies most likely reflects the change from fluvial to lacustrine conditions. The few pollen grains of Picea and Abies in ''post-fluvial time'' samples were brought to the site by the occasional aestival floods and of course by the wind. The distribution of the pollen grains of aquatic and swamp plants - frequent in the samples with little pollen of Picea and Abies - confirms this interpretation and reflects the silting up of the lake.

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. Additionally, the JUDAY oceanic model JOM with 300 µm mesh size and 80 cm ring diameter was used. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

title: Pollen profile from sediment core KB1, Holzminden, Northern Germany

description: The Nachtigall clay pit near Holzminden, northern Germany, is located in a subrosional basin filled with 43 m of interglacial, interstadial and stadial deposits adjacent to the Weser River. The succession separates the Older Middle Terrace from the Younger Middle Terrace of the Weser River. Nachtigall core KB1 (1998) mainly contains silt and clay with intercalated peat layers. The layers of fen peat and intercalated humic silt are between 36 and 22.5 m depth. According to palynological studies, the peat layers and some humic silts were deposited during interglacial and interstadial periods marked by forest vegetation, termed Nachtigall 1 and Nachtigall 2. They are subdivided by a stadial, termed Albaxen. The peat of Nachtigall 1 is interrupted twice by silt and clay strata (Allochthonous Unit I, II) which are reworked sediments of older glacial periods, possibly of late Elsterian or early Holsteinian age. The palynological sequences of Nachtigall and Göttingen/Ottostrasse show the same pattern. Moreover, the contemporaneous pollen profiles of Nachtigall and Göttingen/Ottostrasse can be compared with the Velay pollen sequence (France). The Nachtigall core section 36-26.02 m corresponds to Bouchet 2 - Bonnefond - Bouchet 3 in Velay. The profiles of Velay and Nachtigall are independently correlated to the MIS-timescale and correspond to MIS 7c, 7b, and 7a. TIMS 230Th/U-dating shows ages ranging from 227 + 9/-8 to 201 + 15/-13 ka, which are in good agreement with the inferred MIS 7 age.

description: In 2015 the Marine Ecology lab. (Eriksson Lab. at the Groningen Institute for Evolutionary Life Sciences [GELIFES], University of Groningen, The Netherlands); tested the effect of different intertidal bioengineering bivalve habitats on the sediment community. We did this by adding different small scale (0.5 by 0.5 m) bivalve assemblages to the intertidal; the treatments included blue mussel reefs, cockle beds, dead shell assemblages, different types of fencing a to protect the bivalves from bird and crab predation; and fencing controls to test for fence effects. We measured effects on sediment conditions (OM, cohesion, erosion), diatom community composition and development (species composition based on cell counts and biovolume, chlorophyll a concentrations), and infauna abundance. The field experiment in the intertidal ran from 30 April to 10 June 2015 and complementary field samples were collected around a natural blue mussel bed on the same tidal flat on 7 October 2015 (N 53.489, E 6.230 degrees).

title: Clay mineral distribution in sediment core AND-2A

description: Clay mineral assemblages in sediments from ANDRILL drill core AND-2A were used to reconstruct the Neogene palaeoenvironment. For the first time a clay mineral data set can be presented for southern McMurdo Sound, Ross Sea, Antarctica, that covers an expanded and fairly continuous Lower and Middle Miocene section. Although the occurrence of some authigenic smectites, zeolites and opal-CT documents diagenetic processes, the clay mineral assemblages allow a subdivision of the core into three intervals that reflect changes in provenance and volcanic activity. Interval I (1000–440 mbsf, 20.0–16.5 Ma) is characterised by a dominant sediment source in the Transantarctic Mountains. Frequent and short-term changes in the illite and smectite concentrations were caused by the influx of volcanic sediment components from southern McMurdo Sound and by diagenesis. Interval II (440–225 mbsf, 16.5–15.0 Ma) has much more uniform illite and smectite contents. The assemblage is derived from the Transantarctic Mountains. Interval III (225–0 mbsf, 15.0–0 Ma, containing major hiatuses) shows a distinctly enhanced volcanic influence and sediment components that come from the south of McMurdo Sound. The AND-2A clay mineral assemblages indicate persistent physical weathering conditions and do not mirror the Mid-Miocene Climatic Optimum. They indicate that the climatic changes were probably not strong enough to cause a modification in the weathering regime on the Antarctic continent.
