title: Benthic nitrate reduction process rates from around the Baltic Sea (May 2016)

description: Nitrate reduction process rates (denitrification, dissimilatory nitrate reduction to ammonium rate - DNRA, anammox) were collected during a research cruise to the Baltic Sea during May-June 2016 as part of the Vici Project “Response of the Iron Biogeochemical Cycle on Continental Shelves to Seawater Deoxygenation” and the BONUS-COCOA project. Sediment sampling and incubation experiments were carried out onboard the RV Pelagia (NIOZ, Netherlands, cruise 64PE411). Whole cores were incubated on board at in situ bottom water temperature and oxygen conditions in the dark. Stable isotopically labelled nitrate (15N-NO3-) was added to overlying water and cores were capped according to Nielsen et al. (1992). Three cores were 'sacrificed' over time (2, 4h, 6h, 8h) after 15-NO3- addition by slurrying the surface and sampling for dissolved gas and solutes. Slurry experiments were also carried out in parallel to core incubations at each site (Risgaard-Petersen et al., 2003; Song et al., 2013). Analysis of 15N compounds was carried out at the University of Southern Denmark (Dalsgaard et al., 2013). Process rates were calculated according to Song et al. (2016). In addition to the calculated process rates, the dataset includes the following in situ parameters: bottom water salinity, temperature and oxygen (obtained from CTD sensors), nitrate (measured spectrophotometrically according to Schnetget and Lehners, 2014) and total organic carbon data (derived from Hermans et al., 2019).

title: Fe(II) kinetic data from from water samples during POSEIDON cruise POS533 (AIMAC)

description: At each station, seawater was collected for trace metals sampling at 20 m depth using a Teflon pump (Furon®) with a 40 m Teflon tube connected with a AcroPakTM 1500 capsule w/Supor Memb 0.8/0.2 μm filter. The pump was left to pump to rinse the inner hose and 1 L sample was collected in LDPE bottles (NALGENE) and stored at -20oC until the land-based laboratory analysis. The material was previously cleaned following the trace metals GEOTRACES protocol and the experiments were done in Class 100 clean laboratory or trace metal analysis (QUIMA- IOCAG TM lab).

title: Snow height on sea ice, meteorological conditions and drift of sea ice from autonomous measurements from buoy 2020S99, deployed during MOSAiC 2019/20

description: Snow height was measured by the Snow Buoy 2020S99, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 2) 2019/20. The resulting time series describes the evolution of snow height as a function of place and time between 10 February 2020 and 06 August 2020 in sample intervals of 1 hour. The Snow Buoy consists of four independent acoustic range finder measurements representing the area (approx. 10 m**2) around the buoy. In addition to snow height, geographic position (GPS), barometric pressure, air temperature, and surface 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.
description: The data set has been processed and contains quality flags for different kinds for erroneous data. Flag values are the sum of individual error codes. The value of 0 refers to no error. Quality flag, position: The geographic position is flagged +1 if the drift velocity, as derived from the GPS longitude and latitude, exceeds a threshold of 10 deg latitude or 50 deg longitude per time step; +2 if the position exceeds extreme values, such as longitude &gt; 360 deg; +4 if the position is exactly 0.0. Quality flag, snow: The snow height is flagged for each sensor +1 for manual corrections during processing (e.g. sensor issues); +2 if the snow accumulation exceeds 0.1 m per hour; +4 if the difference in snow height is larger than 0.03 m compared to values within the last and next 2 hours; +32 if the value exceeds the height of sensor on the platform at 1.5 m.Quality flag, temperature: The air temperature is flagged +1 for manual corrections during processing (e.g. sensor issues); + 32 if the value is below – 50 °C.Quality flag, pressure: The barometric pressure is flagged +1 for manual corrections during processing (e.g. sensor issues).

title: Auxiliary data from radiation station 2018R4

description: Solar radiation over and under sea ice was measured by radiation station 2014R4, an autonomous platform, installed on drifting Multi-Year-Ice (MYI) in the Arctic Ocean during Oden_AO18. The resulting time series describes radiation measurements as a function of place and time between 20 August 2018 and 20 December 2018 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of thermistor chain with 208 sensors and several other sensor packages, which measured water temperature and conductivity at hourly intervals. An underwater lightchain measured counts of red, green and blue light at 49 positions at hourly intervals. All times are given in UTC.

title: Hydrogen evolution activities of metagenomic fosmid clones derived from hydrothermal vent systems along the Mid-Atlantic Ridge

description: Metagenomic fosmid libraries were constructed from hydrothermal chimneys and fluids and screened for hydrogenase activity by means of an activity-based screen. The hydrogen evolution activity of protein extracts from positively screened clones was determined by means of gas chromatography. For the most active clone (SP11F2) the hydrogen evolution activity was determined at different pH conditions and the stability of the respective enzyme ectract under different storage conditions was tested. The datasets contain hydrogen evolution activities of fosmid clones from the Sisters Peak, Nibelungen and Lilliput hydrothermal vent fields.
description: Metagenomic fosmid libraries were constructed from the environmental sample and screened for hydrogen uptake activity (Adam and Perner 2018). The hydrogen evolution activity of the fosmid clones has been determined as described in the related publication.
