title: Physical oceanography from CTD measurements during Akademik Tryoshnikov cruise AT2018 to the Arctic Ocean

description: RV "Akademik Tryoshnikov" left Arkhangelsk on August, 17 2018 and on August 22-30, observations in the western part of the Laptev Sea under the auspice of CATS (The Changing Arctic Transpolar System)/Transdrift program were carried out. 42 CTD stations were made.Conductivity, Temperature, and Depth (CTD) profiles of the water column were taken by using a Seabird SBE911plus CTD system. This system measures conductivity, temperature, and pressure at a 24Hz sample rate. Pressure was measured by a Digiquartz® sensor with accuracy of ±0.015% of full-scale range. For temperature measurements an SBE 3T sensor was used with accuracy of 0.005°C. Conductivity was measured by an SBE 4C sensor with accuracy of 0.0003 S/m.All Seabird sensors had been returned to the manufacturer after the 2015 expedition for servicing and calibration, and stored unused since then.This study was supported by the Russian Ministry of Science and Higher Education, project: RFMEFI61617X0076.

title: Particle positions of numerical experiments 1 to 4

description: In mixed sediment beds, erosion resistance can change relative to that of beds composed of a uniform sediment because of varying textural and/or other grain-size parameters, with effects on pore water flow that are difficult to quantify by means of analogue techniques. To overcome this difficulty, a three-dimensional numerical model was developed using a finite difference method (FDM) flow model coupled with a distinct element method (DEM) particle model. The main aim was to investigate, at a high spatial resolution, the physical processes occurring during the initiation of motion of single grains at the sediment–water interface and in the shallow subsurface of simplified sediment beds under different flow velocities. Increasing proportions of very fine sand (D50=0.08 mm) were mixed into a coarse sand matrix (D50=0.6 mm) to simulate mixed sediment beds, starting with a pure coarse sand bed in experiment 1 (0 wt% fines), and proceeding through experiment 2 (6.5 wt% fines), experiment 3 (10.5 wt% fines), and experiment 4 (28.7 wt% fines). All mixed beds were tested for their erosion behavior at predefined flow velocities varying in the range of U 1-5=10–30 cm/s. The experiments show that, with increasing fine content, the smaller particles increasingly fill the spaces between the larger particles. As a consequence, pore water inflow into the sediment is increasingly blocked, i.e., there is a decrease in pore water flow velocity and, hence, in the flow momentum available to entrain particles. These findings are portrayed in a new conceptual model of enhanced sediment bed stabilization.

title: Physical oceanography on board of POLARSTERN (1983-11-22 to 2016-02-14)

description: Measuring temperature and salinity profiles in the world's oceans is crucial to understanding ocean dynamics and its influence on the heat budget, the water cycle, the marine environment and on our climate. Since 1983 the German research vessel and icebreaker Polarstern has been the platform of numerous CTD (conductivity, temperature, depth instrument) deployments in the Arctic and the Antarctic. We report on a unique data collection spanning 33 years of polar CTD data. In total 131 data sets (1 data set per cruise leg) containing data from 10 063 CTD casts are now freely available. During this long period five CTD types with different characteristics and accuracies have been used. Therefore the instruments and processing procedures (sensor calibration, data validation, etc.) are described in detail. This compilation is special not only with regard to the quantity but also the quality of the data - the latter indicated for each data set using defined quality codes. The complete data collection includes a number of repeated sections for which the quality code can be used to investigate and evaluate long-term changes. Beginning with 2010, the salinity measurements presented here are of the highest quality possible in this field owing to the introduction of the OPTIMARE Precision Salinometer.

title: Colored dissolved organic matter (CDOM) and dissolved organic carbon (DOC) measured during cruise TRANSDRIFT-XXIV, Laptev Sea

description: The data set includes the light absorption coefficient of colored dissolved organic matter (CDOM) from 200 nm to 700 nm wavelength and dissolved organic carbon (DOC) together with physical oceanographic observations (temperature and salinity) from the Laptev Sea. Sampling was carried out August and September 2018. During the ship-based expedition, we operated a CTD profiler (conductivity temperature-depth; Seabird 911+) to sample the basic hydrographic parameters. The CTD is operated on a carousel water sampler (SBE 32), which can take water samples at the selected depths.The dataset is part of a multi-year study (different seasons over a period of 9 years: 2010-2019) of the dissolved organic matter (CDOM), which includes observations in marine waters from the coastal zone to the shelf edge of the Laptev Sea and East Siberian Sea, the river Lena and ice and water samples from the land-fast in the south-eastern Laptev Sea.

title: Carbonate associated trace metal and uranium isotope data for the PETM

description: The Paleocene Eocene Thermal Maximum (PETM) represents a major carbon cycle and climate perturbation that was associated with ocean de-oxygenation, in a qualitatively similar manner to the more extensive Mesozoic Oceanic Anoxic Events. Although indicators of ocean de-oxygenation are common for the PETM, and linked to biotic turnover, the global extent and temporal progression of de-oxygenation is poorly constrained. Here we present carbonate associated uranium isotope (δ238UCAU) data to reconstruct the evolution of global seawater δ238U, and hence quantify the expansion of anoxic U sinks on a global scale.This dataset contains trace element and U isotope data (238U/235U, expressed as δ238U) for the carbonate fraction of three well studied PETM sites; Site 865 (equatorial Pacific), Site 401 (Bay of Biscay) and Site 690 (Walvis Ridge). Samples are carbonate rich pelagic sediments, with a mixture of carbonate nannofossils, foraminifera and detrital clays. Bulk samples were selectively leached for the carbonate fraction using 1M ammonium acetate (pH 5) at room temperature for 24hrs. Trace element concentrations were measured on a Thermo-Finnigan Element XR and reported normalized to Ca. Uranium was purified by ion exchange chromatography and isotopes measured on a Thermo-Finnigan Neptune Plus. Uranium isotopes are reported as δ238U, where CRM-145 = 0‰.Sites 690 and 401 both show elevated U/Ca and δ238UCAU during the PETM and recovery interval, indicative of locally reducing conditions. By contrast, Site 865 records the global seawater δ238U and shows no resolvable change across the PETM. The lack of resolvable perturbation to the U-cycle during the event suggests a limited expansion of seafloor anoxia on a global scale. In the related publication we use this result, in conjunction with a biogeochemical model, to set an upper limit on the extent of global seafloor de-oxygenation. The model suggests that the new U isotope data, whilst also being consistent with plausible carbon emission scenarios and observations of carbon cycle recovery, permit a maximum ~10-fold expansion of anoxia to cover &lt;2% of seafloor area.

title: Protective effects of adenosine triphosphate, thiamin, thiamin pyrophosphate, and their combination against linezolid-induced renal injury and lactic acidosis in rats

description: Linezolid, an oxazolidinone antibiotic effective against Gram-positive pathogens, may cause nephrotoxicity and lactic acidosis during prolonged therapy. This experimental study investigated the protective effects of adenosine triphosphate (ATP), thiamin, thiamin pyrophosphate (TPP), and their combination (ATTP) on linezolid-induced renal injury and lactic acidosis in rats. Thirty-six male Wistar rats were randomly divided into six groups (<i>n</i> = 6): healthy control (HG), linezolid only (LZD), ATP+linezolid (ATLZD), thiamin + linezolid (TLZD), TPP+linezolid (TPLZD), and ATP+thiamin + TPP+linezolid (ATTPL). Linezolid (125 mg/kg, orally) was administered twice daily, while ATP (4 mg/kg), thiamin (20 mg/kg), and TPP (20 mg/kg) were given intraperitoneally once daily for 28 days. At the end of treatment, kidney tissues were examined for oxidative stress markers [malondialdehyde (MDA), total glutathione (tGSH), superoxide dismutase (SOD), catalase (CAT)] and histopathology, and blood samples were analyzed for blood urea nitrogen (BUN), creatinine, and lactate. Linezolid increased oxidative stress, suppressed antioxidants, and elevated BUN, creatinine, and lactate levels. ATP partially improved the oxidative balance in renal tissue but failed to prevent hyperlactatemia and impaired renal function. Thiamin did not produce significant changes. TPP markedly improved oxidative stress markers and reduced renal dysfunction. The triple combination provided the most pronounced protection, restoring antioxidant defenses, kidney function, and lactate levels to near-control values. Histopathological evaluation revealed marked tubular degeneration, interstitial hemorrhage, and mononuclear cell infiltration in the linezolid group, which were markedly improved by TPP and combination therapy. These findings indicate that TPP protects against linezolid-induced nephrotoxicity and lactic acidosis, with its efficacy further enhanced by ATP.
