title: Pore-water analyses of permafrost deposits from Byk_98_Mkh (Bykovsky Peninsula in 1998)

description: In order to get information about the pore-water characteristics from the dry samples, the water-soluble elements in the sediments were determined by shaking the samples with a proportionate amount of ultrapure water for a defined period of time. To obtain the water extracts, approximately 1 g of the freeze-dried sample was shaken for approximately 90 minutes in 50 ml centrifuge tubes with ultrapure water at a soil:water ratio of 1:25 using an overhead shaker (Gerhardt Laboshake). Then the suspension was centrifuged (Heraeus Multifuge 3s) at 4000 rpm for 15 minutes. The decanted extraction was filtered through a 0.45 µm cellulose acetate filter. We measured total dissolved elemental concentrations of Al, Ba, Ca, Fe, K, Mg, Mn, Na, P, Si, and Sr and anion concentrations of F-, Cl-, SO42-, Br-, NO3-, PO43-, and HCO3-.The element concentrations were analyzed using inductively coupled plasma-optical emission spectrometry (ICP-OES, Perkin-Elmer Optima 8300DV), while the anion content was determined by ion chromatography (IC, Thermo ICS2100). Hydrogen carbonate concentrations were measured by potentiometric pH-value titration with 0.01 M HCl using an automatic titrator (Metrohm 794 Basic Titrino). In order to estimate the procedural error, extractions were carried out in duplicate for every 5th to 10th sample and 2-3 blank solutions of ultrapure water were treated in the same manner as the extractions and measured for concentrations. Water EC and pH values were measured using a WTW MultiLab 540 multi-parameter device equipped with a TetraCon 325 cell referenced to 25 °C and a pH Sentix 81 electrode.

title: Coordinates and main environmental parameters of the lakes from the River Pechora basin, East European Russian Arctic

description: We investigated surface sediments from the lakes and a short sediment core (lake Bolshoy Kharbey) from the River Pechora basin, East European Russian Arctic. The twenty three investigated lakes have thermokarst, glacial or floodplain origin and are characterised by low mineralization, mostly hydrocarbonat-calcium type of water and low concentration of biogenic elements. The lakes have close to neutral pH, but in 14 lakes pH is less than or equal to 7 and in 2 lakes less than or equal to 6. These two lakes are classified as acidothrophic.

title: Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2018S70, deployed during ODEN cruise AO18

description: Snow height was measured by the Snow Depth Buoy 2018S70, an autonomous platform, drifting on Arctic sea ice, deployed with the icebreaker ODEN during the Arctic Ocean 2018 campaign (AO18). The resulting time series describes the evolution of snow depth as a function of place and time between 06 September 2018 and 04 June 2019 in sample intervals of 1 hour. The Snow Depth Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on multi year ice. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and an internal ice temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy. The data set has been processed, including the removal of obvious inconsistencies (missing values). Records without any snow depth may still be used for sea ice drift analyses.

title: Nutrient concentrations in water samples collected at Station MARCH-1997-GN36199704601MSB06 in the Aegean Sea

description: For oxygen determination samples were analysed on board immediately after collection with the Winkler method according to Carpenter (1965a, 1965b). Titration was done with a Metrohm Dosimat 665 automatic burette. Precision of the method is estimated at 0.05 ml O2/l.Apparent oxygen utilisation (AOU) was calculated according to difference of measured oxygen values and oxygen saturation given by the equations of Benson and Krause (1984), which are recommended by Millero (1986).Percentage of oxygen saturation in water was calculated from the following equation (at temperature 0-40ºC and salinity 0-40 promille): %O2 = (O2/O2') X100, where O2 is oxygen concentration in a sample, O2' is oxygen solubility in sea water at the same temperature and salinity as in the sample.Samples for determination of nutrients were collected in 100 ml polyethylene bottles and kept continuously under deep freeze (-20°C ) until analysis in the laboratory. Nitrate and nitrite were analysed by a Bran and Luebbe Autoanalyser II according to the procedure of Treguer and Le Corre (1975). Phosphate was measured by a Perkin Elmer Lambda 2S UV/VIS Spectrometer according to the method described by Murphy and Riley (1962). Precision is estimated at ±0.1 µmol/l for nitrate and ±0.02 µmol/l for phosphate and nitrite. Detection limit was 0.08 µmol/l for nitrate and nitrite and 0.01 µmol/l for phosphate.

title: Water stable isotope record of ice core NEEM (early Holocene) measured with Continuous Flow Analysis

description: A new technique for on-line high resolution isotopic analysis of liquid water, tailored for ice core studies is presented. We built an interface between a Wavelength Scanned Cavity Ring Down Spectrometer (WS-CRDS) purchased from Picarro Inc. and a Continuous Flow Analysis (CFA) system. The system offers the possibility to perform simultaneuous water isotopic analysis of d18O and dD on a continuous stream of liquid water as generated from a continuously melted ice rod. Injection of sub µl amounts of liquid water is achieved by pumping sample through a fused silica capillary and instantaneously vaporizing it with 100% efficiency in a~home made oven at a temperature of 170 °C. A calibration procedure allows for proper reporting of the data on the VSMOW-SLAP scale. We apply the necessary corrections based on the assessed performance of the system regarding instrumental drifts and dependance on the water concentration in the optical cavity. The melt rates are monitored in order to assign a depth scale to the measured isotopic profiles. Application of spectral methods yields the combined uncertainty of the system at below 0.1 per mil and 0.5 per mil for d18O and dD, respectively. This performance is comparable to that achieved with mass spectrometry. Dispersion of the sample in the transfer lines limits the temporal resolution of the technique. In this work we investigate and assess these dispersion effects. By using an optimal filtering method we show how the measured profiles can be corrected for the smoothing effects resulting from the sample dispersion. Considering the significant advantages the technique offers, i.e. simultaneuous measurement of d18O and dD, potentially in combination with chemical components that are traditionally measured on CFA systems, notable reduction on analysis time and power consumption, we consider it as an alternative to traditional isotope ratio mass spectrometry with the possibility to be deployed for field ice core studies. We present data acquired in the field during the 2010 season as part of the NEEM deep ice core drilling project in North Greenland.

title: The effects of growth phase and salinity on the hydrogen isotopic composition of alkenones produced by coastal haptophyte algae

description: The isotopic fractionation of hydrogen during the biosynthesis of alkenones produced by marine haptophyte algae has been shown to depend on salinity and, as such, the hydrogen isotopic composition of alkenones is emerging as a palaeosalinity proxy. The relationship between fractionation and salinity has previously only been determined during exponential growth, whilst it is not yet known in which growth phases natural haptophyte populations predominantly exist. We have therefore determined the relationship between the fractionation factor, alpha alkenones-water, and salinity for C37 alkenones produced in different growth phases of batch cultures of the major alkenone-producing coastal haptophytes Isochrysis galbana (strain CCMP 1323) and Chrysotila lamellosa (strain CCMP 1307) over a range in salinity from ca. 10 to ca. 35. alpha alkenones-water was similar in both species, ranging over 0.841-0.900 for I. galbana and 0.838-0.865 for C. lamellosa. A strong (0.85 &lt;= R**2 &lt;= 0.97; p &lt; 0.0001) relationship between salinity and fractionation factor was observed in both species at all growth phases investigated. This suggests that alkenone dD has the potential to be used as a salinity proxy in coastal areas where haptophyte communities are dominated by these coastal species. However, there was a marked difference in the sensitivity of alpha alkenones-water to salinity between different growth phases: in the exponential growth phase of I. galbana, alpha alkenones-water increased by 0.0019 per salinity unit (S 1), but was less sensitive at 0.0010 S 1 and 0.0008 S 1 during the stationary and decline phases, respectively. Similarly, in C. lamellosa alpha alkenones-water increased by 0.0010 S 1 in the early stationary phase and by 0.0008 S 1 during the late stationary phase. Assuming the shift in sensitivity of alpha alkenones-water to salinity observed at the end of exponential growth in I. galbana is similar in other alkenone-producing species, the predominant growth phase of natural populations of haptophytes will affect the sensitivity of the alkenone salinity proxy. The proxy is likely to be most sensitive to salinity when alkenones are produced in a state similar to exponential growth.

description: In-situ sea temperatures have been obtained using two Richter and Wiese protected reversing thermometers mounted on a Nansen bottle. Temperature readings, after correction according to the thermometer's calibration certificates are averaged if the temperature difference among thermometers is lower than 0.2°C and repeated otherwise, so that the accuracy can be set to be lower than 0.2°C. Thermometers are periodically controlled at facilities of the Marine Research Institute (ICM) in Barcelona against a high precision Pt100. which, in turn is annually controlled using Ga and pure H2O melting points.
