title: Currents based on ADCP data in a small shallow Lake Vendyurskoe in Russia during 27 March-6 April 2020: AQ1_EXP102_b1

description: The measurements were carried out 27 March–6 April 2020 on small ice-covered shallow Lake Vendyurskoe (62.215784N, 33.262784E, North-Western of Russia). Surface area of the lake is 10.4 km2, its mean and maximal depths are 5.3 and 13.4 m. The maximal length of the lake is 7 km; and the average width is 1.5 km.The mooring equipment was deployed on the ice 350 m from the northern shore, with a location depth of ~ 7 m. The measuring complex included a pyranometer placed directly under the ice to measure downwelling irradiance (a M-80m universal pyranometer, produced in Russia, accuracy 1 W m-2, sampling frequency one minute), two Star-shaped pyranometers (Theodor Friderich & Co, Meteorologishe Gerate und Systeme, Germany, accuracy 0.2 W/m2, sampling interval one minute) placed at one meter above ice surface to measure downwelling and upwelling irradiance, thermistor chain (13 temperature sensors TR-1060 RBR, Canada, accuracy ±0.002°C, resolution ±0.00005°C, sampling frequency 10 s; sensors were placed at intervals of 0.5 m, starting from 0.2 m from the ice bottom to a depth of 6.2 m), and two ADCPs (2 MHz HR Aquadopp current velocity profiler, Nortek AS, Norway).The two ADCPs were mounted on a special retaining frame that rigidly fixed the instruments on the ice and to each other. Both devices were installed in a hole with emitters located 3 cm below the lower ice boundary. For the entire measurement period, the devices were set up as follows: signal discreteness was one minute (32 pulses with a frequency of 2 Hz), depth scanning range was 2.875 m (115 cells with a size of 25 mm). To exclude the mutual influence of the two ADCPs, the emitters were set in an asynchronous mode with a 30 s delay.In the first stage of experiment – from 17:00 LT (local time = UTC + 3 h) on 27 March 2020 to 09:30 LT on 30 March 2020 – the ADCPs emitters were located at a distance of 1.5 m from each other, and at a depth of 1.61 m one beam from each of the devices intersected. In the second stage – from 10:00 LT on 30 March 2020 to 10:00 LT on 6 April 2020 – the distance between the emitters was 0.75 m and two pairs of beams intersected at the same depth.

title: Total carbon and Total organic carbon of sediment core M40/4_SL87, Balearic Rise, Western Mediterranean Sea

description: The data were raised to compare the history of sea-surface temperature (based on the alkenone unsaturation index UK'37), organic and inorganic carbon accumulation, and the ratio of stable nitrogen isotopes 15N and 14N in the Western Mediterranean Basin to that of coeval cores from the Eastern Mediterranean basin. There, periodic anoxia caused the deposition of organic-carbon-rich sapropels over the same time interval in the late Quaternary, but are not expressed in the western basin. The gravity core was taken on the Balearic Rise and was recovered during expedition Meteor 40/4 from 1900 m water depth.
description: Methods:Samples were obtained from cores taken aboard r/v Meteor either during the expedition or in the Core Repository of the Institute of Baltic Sea Research. Samples were punched out of the working halves with sawn-off syringes, wrapped in plastic, and stored frozen until freeze-drying in the shore-based laboratory. The dried bulk sample was homogenized by mortar and pestle.A second subsample was used to determine concentrations of total carbon and organic carbon. Total carbon (TC) analysis was carried out by combustion at 1200°C, followed by coulometric determination of the evolved CO2 (Eltra C-S Analyzer). TOC determination was conducted by combustion, followed by coulometric determination of the evolved CO2 of subsamples that were soaked in 0.1 molar HCl over night and dried to constant weight. The precision determined on replicate sub-samples was 0.1 wt% for TOC contents.

There, periodic anoxia caused the deposition of organic-carbon-rich sapropels over the same time interval in the late Quaternary, but are not expressed in the western basin.

The dried bulk sample was homogenized by mortar and pestle.A third subsample was analysed for the delta15N of bulk sediment nitrogen in a Carlo Erba/Fisons 1108 Elemental Analyzer connected to an isotope-ratio mass-spectrometer (Finnigan Delta S). The reference gas was pure N2 nitrogen from a cylinder calibrated against IAEA standards N-1 and N-2. The standard deviation for replicate samples was less than 0.2‰.

title: Alkenone sea surface temperature estimates of gravity core M40/4_SL67 (eastern Mediterranean Sea)

description: Water column stratification increased at climatic transitions from cold to warm periods during the late Quaternary and led to anoxic conditions and sapropel formation in the deep eastern Mediterranean basins. Here we report downcore sea surface temperature estimates of gravity core M40-4/67 taken in the region of the Rhodes Gyre (eastern Mediterranean Sea) that elucidate the influence of glacial/interglacial temperature changes in determining density of surface waters and formation of sapropels.
description: Methods:Samples were obtained from cores taken aboard r/v Meteor either during the expedition or in the Core Repository of the Institute of Baltic Sea Research. Samples were punched out of the working halves with sawn-off syringes, wrapped in plastic, and stored frozen until freeze-drying in the shore-based laboratory.Subsamples (~1-2 g dry weight) of the homogenized bulk samples were used to extract lipids and to estimate the alkenone unsaturation index, a SST indicator (Brassell et al., 1986). Weighted splits of freeze-dried and homogenized sediments were extracted by ultrasonic agitation with 35-mL CH2Cl2 (2 ' 10 min). Elemental sulfur was removed by the addition of copper foil during the extraction. After each extraction step, samples were centrifuged, and the solvent was collected by pipette. The two lipid extracts were combined and dried in a rotary evaporator. The extracts were redissolved in CH2Cl2 and precleaned over a silica gel column (conditioned with 30-mL CH2Cl2) by elution with 14-mL CH2Cl2 and dried again in a rotary evaporator. The extracts were redissolved in n-hexane and subsequently fractionated using high-pressure liquid chromatography (HPLC). The HPLC column, packed with silica gel was MERCK LiChrospher Si 100-5. Four fractions were obtained using 5.5-mL n-hexane, 14-mL n-hexane/dichloromethane, 9-mL dichloromethane, and 9-mL acetone as eluents. The ketones (here: alkenones) were isolated in the second fraction. The first fraction contained the aliphatic hydrocarbons, and the third and fourth fractions yielded the more polar compounds.Gas chromatographic (GC) analyses were carried out on a HR 8000 Fisons gas chromatograph (FID, cold on-column injection) equipped with a 30-m (0.32 mm ID) glass capillary column (DB5HT). Helium was used as a carrier gas (column head pressure 110 kPa). Oven temperature programming conditions were from 35°C to 300°C at 15°C min-1 followed by an isothermal period of 15 min at 300°C and from 300°C to 330°C at 15°C min-1 followed by an isothermal period of 10 min at 330°C. Alkenones were identified by comparing retention times with those of standards. Peak areas were converted to the UK'37 index, and SSTs calculated according to a global coretop calibration (Müller et al., 1998): SST (°C) = (C37:2 / (C37:2 + C37:3) - 0.044) / 0.033. Alkenone concentrations were determined from GC analyses of the ketone fractions based on peak responses relative to 5alpha-cholestane as an external standard. Results of duplicate analyses (n = 10) are also given.
