title: Physical oceanography and current velocity data from mooring AK4-1 in the Arctic Ocean in 2015-2018

description: Time series data of physical oceanography (seawater conductivity, temperature, pressure, salinity) and ocean current velocities were obtained from mooring AK4 in the eastern Arctic Ocean north of Severnaya Zemlya (82.105 °N, 94.772 °E, water depth 1985 m) in 2015 - 2018. The mooring was deployed during Akademik Tryoshnikov expedition AT2015 as part of the NSF-funded NABOS (Nansen and Amundsen Basins Observational System) - program and recovered during AT2018, which was jointly organized between NABOS and the German BMBF-funded CATS (Changing Arctic Transpolar System)-project. The attached archive contains processed current velocities and hydrographic data recorded with Seabird SBE37 microcats, RDI Acoustic Doppler Current profilers and Aanderaa point current meters. Details on data processing can be found in the file description and in Ruiz-Castillo et al. (2022). Instruments types and serial numbers can be found in the attached document.
description: The records include the processed data from mooring AK4. Current velocities were quality-controlled based on thresholds defined for a variety of parameters. Data points meeting any of the following criteria were discarded: error velocities &gt;10 cm/s, beam correlation &lt;64%, percent-of-good &lt;50%, pitch/roll &gt;20°. Bins with &gt;30% of discarded data points were removed entirely. Velocity flags indicate the evaluated quality of the data point (flag=0: good, flag=1: discarded; flag=2: enhanced error velocity (3-10 cm s-1) and or pitch/roll of 10-20°. Velocities were corrected for magnetic declination. The pressure-values provide the actual CTD pressure readings, depth-values provide the nominal instrument depth. Temperature and salinity flags indicate interpolated gaps in the time series. For more details, please refer to Ruiz-Castillo et al. (Structure and seasonal variability of the Arctic Boundary Current north of Severnaya Zemlya. Journal of Geophysical Research-Ocean, under review).The authors are grateful to the captains, crews and technical/scientific staff of the expeditions. Many individuals have contributed to the conception of the research, the preparation of the instruments, the deployment and recoveries, as well as to the retrieval of the data, which we greatly acknowledge.

title: (Table 1) Stable carbon isotope record and total nitrogen concentration in ODP Hole 175-1085B sediments

description: Variations in the strength of coastal upwelling in the South East Atlantic Ocean and summer monsoonal rains over South Africa are controlled by the regional atmospheric circulation regime. Although information about these parameters exists for the last glacial period, little detailed information exists for older time periods. New information from ODP Site 1085 for Marine Isotope Stages (MIS) 12-10 shows that glacial-interglacial productivity trends linked to upwelling variability followed a pattern similar to the last glacial cycle, with maximums shortly before glacial maxima, and minimums shortly before glacial terminations. During the MIS-11/10 transition, several periodic oscillations in productivity and monsoonal proxies are best explained by southwards shifts in the southern sub-tropical high-pressure cells followed by abrupt northwards shifts. Comparison to coeval sea-surface temperature measurements suggests that these monsoonal cycles were tightly coupled to anti-phased hemispheric climate change, with an intensified summer monsoon during periods of Northern (Southern) Hemisphere cooling (warming). The timing of these events suggests a pacing by insolation over precession periods. A lack of similar regional circulation shifts during the MIS-13/12 transition is likely due to the large equatorwards shift in the tropical convection zone that occurred during this extreme glaciation.

title: Geochemical data from the Cenomanian-Turonian interval of ODP Hole183-1138A

description: Geochemical data from Ocean Drilling Program Site 1138A, core 69, spanning the Cenomanian–Turonian boundary interval (~94 Ma). The data were generated from marine sediment in the archive half of the core, which was opened and sampled for this project following approval from the IODP curatorial advisory board. The data consist of: (i) Bulk organic geochemistry (total organic carbon, hydrogen and oxygen indexes, total inorganic carbon) measured by Rock Eval pyrolysis and coulormat titration; (ii) Bulk organic carbon isotopes, measured on decarbonated sediments; (iii) Bulk sediment elemental concentrations measured by ICP-MS; (iv) Bulk sediment molybdenum isotopes, measured by MC-ICP-MS; (v) n-alkane compound-specific carbon isotopes measured by GCMS-IRMS; (vi) Maceral assemblage compositions, measured by visual petrography.

title: REVEALS reconstruction of past vegetation cover with optimized RPP values for European samples

description: This data set presents the reconstructed vegetation cover for 1451 European sites based on harmonized pollen data from the data set LegacyPollen 2.0 and optimized RPP values. Sugita's REVEALS model (2007) was applied to all pollen records using REVEALSinR from the DISQOVER package (Theuerkauf et al. 2016). Pollen counts were translated into vegetation cover by taking into account taxon-specific pollen productivity and fall speed. Additionally, relevant source areas of pollen were also calculated using the aforementioned taxon-specific parameters and a gaussian plume model for deposition and dispersal and forest cover was reconstructed. In this optimized reconstruction, relative pollen productivity estimates for the ten most common taxa were first optimized by using reconstructed tree cover from modern pollen samples and LANDSAT remotely sensed tree cover (Sexton et al. 2013) for Europe. Values for non-optimized taxa for relative pollen productivity and fall speed were taken from the synthesis from Wiezcorek and Herzschuh (2020). The average values from all Northern Hemisphere values were used where taxon-specific continental values were not available. We present tables with optimized reconstructed vegetation cover for all records in Europe. As further details we list a table with the taxon-specific parameters used and a list of parameters adjusted in the default version of REVEALSinR.

title: Magnetic data of profile MSM122_P04-1 over the Oceanographer transform fault, North Atlantic, of MARIA S. MERIAN cruise MSM122

description: During the cruise MSM122 of the German research vessel MARIA S. MERIAN, we recorded densely spaced magnetic field measurement over the Oceanographer and Hayes transform faults in the North Atlantic to the Southwest of the Azores and hence at segment boundries offseting the Mid-Atlantic Ridge. Additional data were recorded to the south of Hayes transform and on the transits to Halifax outside of any territorial water.The total magnetic field was measured using two SeaSpy magnetometers which were towed at 350 m and 450 m, respectively, behind the stern of the ship, sampling the data continuously every 2 seconds. The ships navigation was corrected to match the position of the first magnetic sensor at 350 m behind the vessel. Uncorrected total field magnetic data are available in text/ascii format.
