title: Experimental investigation of liquid interface stability during the filling of a tank in microgravity

description: The storage of propellants in space as well as the transfer and filling of spacecraft tanks is a prerequisite for future long-term space exploration missions. In this work, the vented filling of a partially filled tank, which is envisioned as a spacecraft tank, was investigated experimentally under compensated gravity in the Bremen Drop Tower. Experiments were performed with a partially filled tank and a test liquid HFE-7500. The drop tower provides 9s of compensated gravity. The shape of the free liquid surface inside a right circular cylinder changes from the normal gravity configuration to a free fall configuration during the test. The fillling was initiated after 3.5s and continued until the end at 9s. The interaction of the incoming liquid jet with the liquid interface was studied for different volumetric flow rates. A stable, but not steady liquid interface was characterized by a deformation due to the incoming liquid jet and the formation of a geyser. The growth of the geyser and the following disintegration into liquid droplets indicated an unstable liquid interface. Subcritical, critical and supercritical regimes of the volumetric flow rates were identified to classify stable and unstable liquid interfaces. The critical Weber number was found to be 1.04, which corresponds to a critical volumetric flow rate of 1.30mL/s. This critical Weber number was compared with the existing literature. Additionally, the behaviour of the liquid interface during the reorientation of the liquid inside the tank was observed.

title: Timing and duration of fishing seasons for artisanal bluefin tuna traps at four sites in Italy, 1896-2010

description: This data set contains data for the start, end and duration of the fishing season for artisanal bluefin tuna fishing traps located at four sites in Italy during 1896-2010. The data have been recovered from historical records, reports and archives associated with the traps.
description: Corresponding authors: Teresa Romeo (teresa.romeo@szn.it) and Brian R. MacKenzie (brm@aqua.dtu.dk)The project was supported by the participating institutes. An initial travel grant (Short Term Scientific Mission) was provided to BRM from the EU COST Action IS1403 (Oceans Past Platform: OPP) to visit colleagues (TR, PB, PC, FA) at Milazzo, Italy to discuss and plan project objectives and data recovery.The trap locations Favignana and Formica are close (ca. 10 km) to each other. The data for these two sites were only available as a combined sum for the 1970s and for a few single daily observations in other years. In years when only combined catch data from both traps were available, the event code is listed as "FavignanaFormica" and spatial coordinates are a simple average of latitudes and longitudes for the two individual sites. Similarly, the minimum and maximum depth of the rooms of the trap are averages of the minima and maxima.

title: Particulate organic matter from POLARSTERN cruise PS113 (ANT-XXXIII/4), Punta Arenas - Bremerhaven, 2018-05-08 - 2018-06-11

description: This data set was collected in support of an investigation of the variability of particulate organic matter content and composition across a high-resoultion latitudinal transect across the Atlantic Ocean during the PS113 expedition. 4L of seawater from the clean ships' underway system were filtered on a 0.7 µm pre-combusted GFF filter. Samples were snap-frozen and stored at -80°C while at sea. Samples were acid fumed and dried before analyses. Particulate organic carbon and particulate nitrogen contents were measured using an Euro EA elemental analyzer (CHNS; EuroVector, Italy). This data reflects high-resolution spatial variabilites in particulate organic carbon and particulate nitrogen concentrations in surface waters accompanied by few samples from higher depths (0 - 400 m).

title: Amino acid concentration and isotopic composition in sedimentary 13C-labeling incubation of sediment core HE483/25-2

description: Amino acids derivatization and analysis: Sediment slurries were centrifuged to separate the sediments from the medium and the sediments were freeze-dried and homogenized. 50 mg of samples spiked with the internal reference standard norleucine were decalcified and acid hydrolyzed (6M, 110℃) for 15 h. The hydrolysate was centrifuged to remove the sediments and subsequently defatted with hexane/ DCM mixture (V/V, 2:1) three times. The purification and derivatization of amino acids were performed by following the protocols described by Takano et al.53 and Chikaraishi et al.54, respectively. In brief, the hydrolysates were evaporated under N2 gas to dryness and purified using Dowex 50WX8 200 400 mesh cation exchange resin to eliminate the matrix effects. The purified amino acids were then isopropylated with a mixture of isopropanol and acetyl chloride (4/1, v/v) at 100 ℃ for 2 h. The solution was then evaporated to dryness and followed 3 times with DCM addition and evaporation to remove any remaining reagent. The AA isopropyl esters were then acylated using a mixture of pivaloyl chloride and DCM (1/1, v/v) at 100 ℃ for 2 h to obtain pivaloyl-isopropyl ester (Pv/AA/iPr). The Pv/AA/iPr solution was then evaporated to dryness and followed 3 times DCM addition and evaporation to remove any remaining reagent. Liquid-liquid extraction was performed by using MiliQ water and a hexane/DCM mixture (2/1, v/v). The Pv/AA/iPr were stored frozen (-20℃) and dissolved in ethyl acetate before analysis.

title: Column-averaged dry-air mole fractions of CO2, CH4, and CO from direct sunlight measurements above the Pacific during the MORE-2 campaign 2019

description: Measurements of atmospheric column-averaged dry-air mole fractions of carbon dioxide (XCO2), methane (XCH4), and carbon monoxide (XCO) have been collected across the Pacific ocean during the Measuring Ocean REferences 2 (MORE-2) campaign in June 2019. We deployed a ship-going variant of the EM27/SUN Fourier Transform Spectrometer (FTS) on board the German research vessel 'Sonne' which, during MORE-2, crossed the Pacific ocean from Vancouver, Canada, to Singapore. Equipped with a custom-built fast solar tracker, the FTS operated in direct-sun view during the ship cruise reliably delivering solar absorption spectra in the shortwave infrared spectral range 4000 to 11000 1/cm. After filtering and bias correcting the dataset, we report on XCO2, XCH4, and XCO measurements for 19 days along a trajectory that largely aligns with 30° N of latitude between 140° W and 120° E of longitude. The dataset has been adjusted to the TCCON (Total Carbon Column Observing Network) station in Karlsruhe, Germany, before and after the MORE-2 campaign through side-by-side measurements. During the campaign the precision for hourly means is found 0.24 ppm, 1.1 ppb, and 0.75 ppb for XCO2, XCH4, and XCO, respectively.

title: DIC concentration and isotopic composition in sedimentay 13C-labeling incubation of sediment core HE483/25-2

description: DIC measurement: an aliquot of the slurry was filtered with a 0.2-µm filter to remove cells and other particles. After filtration, 1 mL of samples were acidified with 100 μL 45% phosphoric acid overnight in an Exetainer® vial pre-purged with CO2-free air before analysis. All samples were measured with a Delta Ray Isotope Ratio Infrared Spectrometer (IRIS) with URI Connect and autosampler (Thermo Fisher Scientific, Germany) with an analytical error of ±1‰. All isotopic values are reported in the delta notation as δ13C relative to the Vienna PeeDee Belemnite (VPDB) standard. Deviations of triplicate isotopic measurement of sample DIC were between ± 1‰ and ± 1,000‰ (for DIC with label uptake of &gt;10,000‰). DIC concentration was calculated from the released amount of CO2 by calibration with sodium hydrogen carbonate solution.

title: Current and echo backscatter measurements on the Laptev Sea shelf in 2013-2014 at mooring site Vilkitzky-13

description: The Vilkitzky-13 mooring was deployed in September 2013 at a water depth of 320 m in the ~250 km-long submarine 'Vilkitzky Trough' in the seasonally ice-covered Laptev Sea (Siberian Arctic) and recovered in September 2014. The location of the mooring is characterized by the transport of water masses from the shallow shelf of the Kara and Laptev Seas to the Arctic boundary current. The 291-m-long mooring was equipped with RDI-Workhorse ADCPs for current measurements and Seabird SBE37 CTDs for temperature and salinity measurements (doi.org/10.1594/PANGAEA.924043). The current was recorded at intervals of 2 m (300 kHz ADCP, 5 to 25 m water depth) and 5 m depth (150 kHz ADCP, 46 to 171 m water depth). The measurement interval was 1 hour. The ADCP current measurements were corrected for declination. The declination was calculated using the Enhanced Magnetic Model (EMM2017 on NOAA.gov.). Due to erroneous measurements caused by a technical problem, the data from the 150 kHz ADCP recorded between the seabed and a water depth of 176 m were discarded. A total of four moorings (1893, Taymyr, Kotelny, Vilkitsky) were deployed on the shelf of the Laptev Sea in September 2013 during the Transdrift 21 expedition and recovered in September 2014 during Transdrift 22 on board the research vessel Viktor Buinitsky (doi.org/10.1594/PANGAEA.908837). The expeditions were carried out as part of the German-Russian partnership Laptev Sea Systems and the BMBF-funded Transdrift project.
