Physical oceanography during G. O. Sars cruise GS2018108 to an Arctic deep-sea sponge ground in 2018

Ulrike Hanz
Deep-sea sponge grounds are hotspots of benthic biomass and diversity. To date, very limited data exists on the range of environmental conditions in areas containing deep-sea sponge grounds and which factors are driving their distribution and sustenance. We investigated oceanographic conditions at a deep-sea sponge ground located on an Arctic Mid-Ocean Ridge seamount. Hydrodynamic measurements were performed along CTD transects and a lander was deployed within the sponge ground that recorded near-bottom physical properties as...

Camille Saurel, Christian Mohn, Kasper Andersen, Lars Andersen, Finn Bak, Pascal Barreau, Janus Larsen, Marie Maar, Niels Peter Nielsen, Ane Pastor & Jens Kjerulf Petersen
As part of a research project supported by the European Marine Fishery Fund and the Danish Fisheries Agency (grant no. 33113-I-16-011) and the Danish Centre for Environment and Energy at Aarhus University, field studies were conducted in two different areas of the Limfjorden, in Lovns Bredning (26th February to 4th March 2017) and in Løgstør Bredning (6-10th March 2017). In each sampling area, 16 fixed-position moorings were deployed in two circular sensor arrays around a...

Soil profiles of pyrite, including underlying drivers, in coastal vegetated habitats

Gloria Maria Susanne Reithmaier & Damien T Maher
Coastal vegetated habitats, including mangroves, saltmarshes and seagrasses, mitigate climate change by storing atmospheric carbon. Previous blue carbon research has mainly focused on organic carbon stocks. However, recent studies suggest that lateral inorganic carbon export might be equally important. Lateral export is a long-term carbon sink if carbon is exported as alkalinity (TAlk) produced via sulfate reduction coupled to pyrite formation. This dataset evaluates drivers of pyrite formation in coastal vegetated habitats and estimates global...

Mats A Granskog, Jørgen Berge, Finlo Cottier, Dmitry V Divine, Christian Katlein, Polona Itkin, Lasse Mork Olsen, Daniel Vogedes & Pedro R De La Torre
Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2020T61 (a.k.a. UiT0206) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 2) in February 2020. The thermistor chain was 5 m long with 250 evenly distributed temperature sensors.The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of...

Schrattenkarst speleothem geochemistry

Paul S Wilcox
This dataset includes speleothem cabon isotopes, oxygen isotopes, U-Th ages, and fluid inclusion hydrogen isotopes used to reconstruct climate in the Swiss Alps during the Last Interglacial period (~129 and 116 ka). The speleothems were collected from caves in the Malchsee-Frutt region of Switzerland (46°47' N, 8°16'E, ~1720 m.a.s.l.). The four speleothems (M37-1-16A, M37-1-16C, M6-73-3, and M37-1-23A) used in this dataset were found broken and inactive in the caves. The speleothems represent a stacked record,...

Irene Esteban, Marion K Bamford, Alisoun House, Charlotte S Miller, Frank H Neumann, Enno Schefuß, Justin Pargeter, Hayley C Cawthra & Erich C Fisher
Waterfall Bluff, in Eastern Mpondoland (Eastern Cape Province, South Africa), is a recently excavated archaeological site with deposits spanning Marine Isotope Stage (MIS) 3 to the Middle Holocene. Here, we present preliminary results of a multi-proxy palaeoenvironmental study combining macro-botanical remains, charcoal, phytoliths, pollen and plant waxes derived from the same archaeological record.

PIES and altimeter derived time series in the eastern North Atlantic (47°N) and in the North Atlantic at the Mid-Atlantic Ridge

Hannah Nowitzki, Monika Rhein, Achim Roessler, Dagmar Kieke & Christian Mertens
For quantification of the exchange of water between the subtropical and subpolar regime in the eastern North Atlantic, data from inverted echo sounders (PIES) that were deployed in 2016-2017 at the 47/48°N transect is used to calculate meridional baroclinic and barotropic transport time series. The baroclinic PIES transport time series is extended to the period 1993-2017 using altimeter data. Furthermore, the correlation between altimeter and PIES derived sea surface height fluctuations is studied using data...

Mg/Ca and oxygen isotope data from the Indo-Pacific

Sindia M Sosdian & Caroline H Lear
Across the middle Miocene, Earth's climate underwent a major cooling and expansion of the Antarctic ice sheet. However, the associated response and development of the tropical climate system is not fully understood, in part because this is influenced by both global climate and also low latitude tectonic gateways and paleoceanography. Here we use combined δ18O and Mg/Ca of planktic foraminifera to reconstruct the thermal history and changes in hydrology from the Indo-Pacific region from 16.5...

Field measurements of fault planes, slip direction, tectonic stylolites, joints and bedding in Mesozoic rocks in Northern Bavaria (Germany)

Saskia Köhler, Jonas Bücker, Nico Hofmann & Daniel Koehn
This data set contains field measurements of the orientation of fault planes, tectonic stylolites, joints and bedding in outcrops consisting of Mesozoic sedimentary rocks in Northern Bavaria (SE Germany). For faults we measured the respective slickensides (striation, teeth) and slip tendency as well. As far as the teeth are perpendicular to the plane of the tectonic stylolites they are measured as planes. In the case of oblique teeth we measured the teeth orientation as linear.In...

Archaeobotanical investigations at Upleward 2, Ldkr. Aurich, Germany

Felix Bittmann & Steffen Wolters
During a rescue excavation in 2003 at the Wurt Upleward, NW-Germany, two houses of early Medieval age were detected. From one of the profile with several cultural layers samples have been taken and analysed. In addition two parallel auger cores were drilled from the lowermost level with the aim to get to or close to the base of the Wurt. Five radiocarbon dates spanned from the late Iron Age to the early medieval.

RTG 2300 - Enrichment of European beech forests with conifers

Christian Ammer, Peter Annighöfer, Niko Balkenhol, Dietrich Hertel, Christoph Leuschner, Andrea Polle, Norbert Lamersdorf, Stefan Scheu & Jonas Glatthorn
Climate change will substantially alter native forest ecosystem dynamics. Increased storm frequencies and severities and longer summer droughts are major threats for the provision of ecosystem goods and services (EG&S) from forests. To adapt forests stands to climate change, two silvicultural measures have been proposed: (i) the promotion of mixed stands and (ii) the integration of exotic tree species that are expected to be adapted to future climatic conditions (in particular from areas with a...
