title: Video footage of the benthos and accompanying oceanographic CTD data recorded along a transect at station 19-10 of RV Meteor cruise M179/2 in the Canal Ballenero / Puerto Engaño (Tierra del Fuego, Chile)

description: A custom-built observation frame (ROVOS) based on Ocean Module V8Sii ROV (Remotely Operated Vehicle) technology was launched from RV Meteor and towed along a 235 m transect in the Ballenero Channel in front of Puerto Engaño, staring in a depth of 51 m progressing slope downward to a depth of 65 m. The sandy seabed is covered by stones and rocks with a dominating community of sessile sea cucumbers.The instrument was equipped with three cameras with different perspectives: one HD camera (Kongsberg oe14-502, 720p50) pointed isometrically forward at an angle of 22.5° to the horizon, the second 4k camera (SubC Imaging Mk6, 2160p25) was oriented downward and an observation camera (Bowtech L3C-650-L, 240p24) provided a low-resolution view forward. Environmental data was recorded with a CTD (RBR Maestro), which included sensors for chlorophyll a, turbidity, oxygen, pH and PAR in addition to standard instruments for conductivity, temperature and pressure. The position of the ROVOS was recorded with the ship's own Posidonia USBL. The global orientation with respect to magnetic north was determined with an internal IMU device. To determine the true image scale on the high-resolution footage, a series of reference lasers indicating 10 cm were used in addition to an altimeter (Tritech) providing acoustically measured heights from the SubC camera to the seabed (see metadata).

title: Grain size in Hashilan Wetland sediment core, western Iran

description: For grain size, prior to grain size analyses, OM was removed by H2O2 (30 %) and carbonates were destroyed with HCl (10 %) from samples. For dispersion, 20 ml of Calgon [(NaPO3)n] was added and agitated overnight. On the next day, analyses were performed with a laser diffraction particle-size analyzer (Beckman Coulter LS 200) after ultrasonic treatment for 30 s. Each sample was measured at least four times for 60 s until a stable distribution was reached. Thereafter, the arithmetic mean was calculated for the best three sample runs. Grain size distributions and all statistical grain size parameters were calculated from the output of the LS 200 as geometric graphical measures according to Folk and Ward (1957) with the MS Excel-based macro Gradistat, Version 8.0 (Blott and Pye, 2001). Analyses were carried out in the GEOPOLAR lab at the University of Bremen.

title: Carbonate content and δ¹³Corg from the Col de Pré Guittard section CPG-2 (Aptian-Albian, Vocontian Basin, France)

description: The calcium carbonate content and δ¹³Corg were measured at Biogeosciences laboratory, Université de Bourgogne/Franche-Comté in Dijon, France. The δ¹³Corg was measured on carbonate-free residues. Sample powders were reacted with HCl (2 N) at room temperature for 24 h to remove carbonate phases. Residues were rinsed with deionized distilled water until neutral, centrifuged (4500 rpm for 15 min), and dried at 50 °C overnight. Aliquots of dried decarbonated samples (~ 7–50 mg) were then weighed in tin capsules. The δ¹³Corg measurements were performed on a Vario MICRO cube elemental analyzer (Elementar, Hanau, Germany) coupled in continuous flow mode to an IsoPrime stable isotope ratio mass spectrometer (Isoprime, Manchester, UK). USGS40 L-Glutamic acid (C = 40.8 wt%; δ¹³CVPDB = -26.39 ± 0.04 ‰) and IAEA-600 Caffeine (δ¹³CVPDB = -27.77 ± 0.04 ‰). The carbon isotopic composition is expressed in delta notation and reported in per mil (‰) relative to the Vienna Pee Dee Belemnite (V-PDB) standard; external reproducibility based on duplicate analyses of samples is better than ± 0.2 ‰ (1σ).

title: Video footage of the benthos and accompanying oceanographic CTD data recorded along a transect at station 15-9 of RV Meteor cruise M179/2 in the Canal Magdalena (Tierra del Fuego, Chile)

description: Underwater video recordings of the benthos and accompanying oceanographic CTD data of the environment recorded during 19 seabed transects (depth between 15-320 m) in the fjords and channels near the Strait of Magellan, the Beagle Channel and Cape Horn. The study areas cover a large part of south-western Tierra del Fuego.A custom-built observation frame (ROVOS), based on Ocean Module V8Sii ROV (Remotely Operated Vehicle) technology, was launched from the RV Meteor and towed along 100-500 m transects at an average velocity of 0.1 kn. The device was equipped with three cameras with different perspectives: One HD camera (Kongsberg oe14-502, 720p50) pointed isometrically forward, the second 4k camera (SubC Imaging Mk6, 2160p25) was oriented downward and an observation camera (Bowtech L3C-650-L, 240p24) provided a low resolution view forward. Environmental data was recorded with a CTD (RBR Maestro), which included chlorophyll a, turbidity, oxygen, pH and PAR sensors, in addition to standard conductivity, temperature and pressure instruments. Additional CTD data are available from water profiles (Schwalfenberg, in preparation). The position of the ROVOS was recorded with the ship's own Posidonia USBL. The global orientation with respect to magnetic north was determined with an internal IMU device.The video footage gives a comprehensive impression of the unique local cold-water ecology and particularly highlights the different composition of the prevailing communities at different depths and on changing substrates. Some of the 19 stations are repeated transects that were already carried out on a research trip in 1994 in order to analyse long-term developments.

title: Radiocarbon dating of Hashilan Wetland sediment core, western Iran

description: Eleven samples including organic sediment, seeds, and charcoal fragments were picked from the Hashilan sediment core and submitted to the Beta Analytic Radiocarbon Dating Laboratory, Miami. The AMS 14C dates were calibrated using the Northern Hemisphere terrestrial calibration curve IntCal20 (Reimer et al., 2020). The Bayesian age-depth model was generated using the rbacon package (Blaauw and Christen, 2011) and the RStudio software (R Development Core Team, 2013). The 95% confidence intervals are based on a 2σ range of average iterations.

title: Inorganic nutrients measured on water bottle samples from CTD/Water sampler-system during RV POLARSTERN cruise PS129

description: The aim of the sub-project HAFOS-nutrients was to determine the nutrients phosphate, nitrate, silicate, nitrite and ammonium in water samples from the entire water column in order to obtain nutrient sections through the Weddell Sea: 954 water samples were taken, in total; 4770 data points for all the different nutrients were measured. The determination of nutrients and biogeochemical parameters is closely connected with physical and biological investigations. The development of phytoplankton blooms and particulate organic matter flux is especially dependent on the available nutrients. Nutrients are also well suited as tracers for the identification of water masses. This work was carried out to continue the investigation of the seasonal as well as the interannual variability of nutrients in the Antarctic Circumpolar Current (ACC) and the Weddell Gyre. In comparison to similar transects of former years, our work focused especially on the transect from Kapp Norvegia to Joinville Island (Hoppema et al., 2015).

title: Mooring-based (YS03) data collected in the period October 2013-June 2014 in Young Sound, Greenland

description: Time series of currents were obtained in the period October 2013 and May 2014 by use of an ice-tethered mooring in Young Sound, Greenland. At YS03 (74.310 N, 20.304 W) The mooring consisted of a 300 kHz downward-looking Teledyne RDI Workhorse Sentinel acoustic Doppler current profiled (ADCP) measuring horizontal and vertical current velocities. Velocity precision and resolution were ±1% and ±5 cm s, respectively, while compass accuracy and resolution were ±2 and 0.1 degrees. The ADCP was set to sample 39 bins (bin size of 2m), where each 10 min sample consists of averages of 20 pings. The first and last bins were set at 6 and 84 m depth. Velocities were corrected for magnetic deviation (18.5) and samples with insufficient acoustic backscatter in the water column were eliminated with the RDI ADCP software. For further details see Boone et al., 2017 (Circulation and fjord-shelf exchange during the ice-covered period in Young Sound-Tyrolerfjord, Northwest Greenland (74o N). Estuar. Coast. Shelf Sci., 15, 194-205. https://doi.org/10.1016/j.ecss.2017.06.021 ).
