Andrey Epimakhov, Daria Kisileva, Igor Chechushkov, Maksim Ankushev & Polina Ankusheva
The present dataset contains measurement of biovalable strontium isotopes (87Sr/86Sr) gathered in the southern Trans-Urals. There are four samples types, such as wormwood (n = 95), leached soil (n = 95), water (n = 93) and freshwater mollusks (n = 74), collected to measure bioavailable strontium isotopes. The analysis of Sr isotopic composition was carried out in the cleanrooms (6 and 7 ISO classes) of the Geoanalitik shared research facilities of the Institute of Geology...

Sedimentology, mineralogy, and geochemistry results of core Arc7-E25 from southern Mendeleev Ridge, Arctic Ocean

Tengfei Song, Claude Hillaire-Marcel, Anne de Vernal & Yanguang Liu
The 320 cm long gravity core E25 (Arc7-E25, 179.4°E, 79.0°N; 1200 m) was retrieved from the southernmost Mendeleev Ridge during the 7th cruise of the Chinese Arctic expedition on the R/V Xue Long in 2016. In combination with the 14C ages, U-Th series measurements analyzed at Geotop-UQAM in 2019 have been used to set up the chronostratigraphy. In addition, TOC and its 13C, grain size distribution, and bulk mineralogy have also been analyzed to evaluate...

Maastrichtian composite bulk carbonate stable isotopes, XRF scanning, biogenic barium, and benthic foraminiferal records from Shatsky Rise, ODP Sites 1209 and 1210

Ji-Eun Kim, Thomas Westerhold, Elizabeth M Griffith, Laia Alegret, Anna Joy Drury & Ursula Röhl
A bulk composite carbonate stable isotope, X-ray fluorescence (XRF) scanning (elemental barium), biogenic barium and benthic foraminiferal record in deep sea sediments from the tropical Pacific was produced from 71.5 to 66 million years ago to determine variations in carbon export in the Pacific during the Maastrichtian. The cores were drilled on Shatsky Rise in the tropical Pacific at Ocean Drilling Program (ODP) Leg 198 Sites 1209 and 1210 whose current locations are 32°39.1081′N, 158°30.3564′E...

Heat flow measurements on METEOR cruise M86/5

Norbert E Kaul & Christian Hensen
Mud volcanoes (MV) are sources of mass and energy, transported from deeper levels of the sediment pile to the surface. Together with fluid and gas, thermal energy is emitted through these structures. Therefore heat flow determination is a sensible tool to detect and quantify the amount of convective flow. In the Gulf of Cadiz several mud volcanoes can be found along major tectonic lines (SWIM faults). We employ geothermal measurements to observe the activity of...

Sun Photometer Data (RAW) from Ny-Ålesund, Svalbard (AWIPEV)

Sandra Graßl & Christoph Ritter
Voltages are measured by a sun photometer, type SP1a by Dr. Schulz & Partner GmbH in 17 wavelengths between λ = 369nm to 1023nm with a field of view of 1° × 1° and a time resolution of 1 minute. In winter 2012/13 a new sun photometer was installed and just 10 of 17 wavelengths remained in the same wavelength range. With the nine out of ten wavelengths optical parameters like the AOD are computed....

A reference section through fast-spread lower oceanic crust, Wadi Gideah, Samail Ophiolite (Sultanate of Oman): Petrographic Data Table and Mineral analyses performed by EPMA

Jürgen Koepke, Dieter Garbe-Schönberg, Tim Müller, Dominik Mock, Samuel Müller & Sobhi Nasir
In the absence of a complete profile through fast-spreading modern oceanic crust, we established a reference profile through the paleo crust of the Samail Ophiolite (Sultanate of Oman), which is regarded as the best analogue for fast-spreading oceanic crust on land. To establish a coherent data set, we sampled hard rocks in the Wadi Gideah in the Wadi-Tayin massif from the mantle section up to the sheeted dikes. This paper reports our studies of the...

Data of magnetic storms and term-day observations from the Prague-Clementinum observatory (1839-1849)

Pavel Hejda, Miloš Revallo & Fridrich Valach
We provide in digital form unique data observed at Prague-Clementinum in years 1839-1849. The data were obtained by digitising and processing the original old records published in the yearbooks of this historical observatory. The data contain two categories of high cadence observations of magnetic declination and horizontal intensity. The first of these categories captures 73 magnetic storms with their magnitude being of at least a moderate level. The second category is the dense observations during...

AMD16_117Q marine sediment core: foraminifera, lipid biomarkers and productivity proxies

Rebecca Jackson
Datasets produced as a result of analyses on calypso giant gravity core (CASQ) AMD-117Q and box core (BC) AMD16-117Q-BC1-1 onboard the CCGS Amundsen GreenEdge/ArcticNet 2016 Leg 1a expedition. Marine sediment cores cover the Holocene period and were recovered off the coast of Qaanaaq, northernmost Baffin Bay. Discrete subsamples were taken from U-channels for analysis of geochemical, palynological and micropaleontological analysis, with the aim of reconstructing palaeoceanographic conditions in the region of the North Water Polynya.

Sporomorph counts, diversity, DCA and climate estimate calculations from ODP Hole 113-696B

Nick Thompson, Ulrich Salzmann, Adrián López-Quirós, Peter K Bijl, Frida Hoem, Johan Etourneau, Marie-Alexandrine Sicre, Sabine Roignant, Emma Hocking, Michael Amoo & Carlota Escutia
A total of 35 samples from the late-middle Eocene to earliest Oligocene (643.73-520.88 mbsf) were analysed for their pollen and spore content. Slides were analysed using a Leica DM500 and Leica DM2000 transmitted light microscopes at 200x and 1000x magnification. Where possible, counts of 300 (excluding reworked grains) sporomorphs were made. Only samples containing 50 or more in situ sporomorphs were used for further analysis and evaluation. Sporomorph diversity was measured using both the Shannon–Wiener...

Friction velocity dependence, cohesion, and XRD data of marine sediments from IODP Site U1301, Juan de Fuca plate

Katja Stanislowski, Alexander Roesner & Matt J Ikari
To investigate the lithostratigraphic position and frictional behavior of the shallow plate boundary fault at the northern Cascadia subduction zone, we conducted laboratory friction experiments on sediments recovered at IODP Site U1301. We used a single-direct shear device under room temperature conditions with 3.5% simulated seawater to perform cohesion tests, plate rate tests and velocity step tests (VST). Friction data from VSTs were inversly modelled to obtain rate- and state friction (RSF) parameters.
