title: Vertical profiles of nitrous oxide, methane and nutrients in coastal water of eastern South Pacific

description: Between February 8th and March 4th 2007 an oceanographic cruise (Galathea 3 expedition) on board of Research Vessel Vædderen (Denmark) was performed Legs 13 and 14 of that expedition were devoted to the study of the oxygen minimum zone off northern Chile and Peru The cruise track covered the area between Valparaiso-Chile (32°S) and northern Peru (7.5°S) from total amount of 18 stations visited, we present 21 station with relatively high vertical resolution of Nitrous oxide and other variables. The main objective of the cruise was to study of low oxygen conditions over microbial communities and metabolic pathways related to the N and C cycles. In this region, an emblematic Oxygen Minimum Zone (OMZ), mainly defined by the presence of Subsurface Equatorial Waters (ESSW) between 50 and 400 m depth. These waters determine an important role of the eastern South Pacific in global climate related to the production of green house gases such as CO2, CH4 and N2O. During the cruise researcher was focused on several mechanisms of N and C transformation in the OMZ such as Fixation of molecular nitrogen (N2) and nitrous oxide (N2O) in surface waters and the core of the oxygen minimum zone and production and consumption of N2O by denitrificion and even nitrification. Continuously sampled variables are temperature, salinity and disolved oxygen, obtained unsing a CTD-O probe (SeaBird). Discretely sampled variables are water samples, collected using Niskin bottles attached to rosette sampler, in order to obtain discrete measurements of dissolver oxygen (O2) and nutrients (NO3, NO2, SiO4 and PO43). Discrete samples of DO (in triplicate) were analyzed using the AULOX measurement system, an automatic Winkler method. Samples for NO2, NO3 and PO4 (15 mL in triplicate) were filtered (using a 0.45 μm GF/F glass filter) and stored (frozen) until analysis, using standard colorimetric techniques (Grasshoff, 1983). Measurements of NH4 (40 mL, in triplicate) were carried out using the fluorometric method proposed by Holmes et al. (1999). N2O and CH4 samples were taken in triplicate in 20 mL vials and carefully sealed to avoid air bubbles. They were then preserved with 50 μL of saturated HgCl2 and stored in darkness until analysis. N2O and CH4 was analyzed by creating a 5 mL headspace of ultrapure Helium and then equilibrated to 40◦C. Mesurements were carried out through gas chromatography using an electron capture detector (Varian 3380) and Flame Ionization detector (Shimadzu 17A), respectively. The calibration curves used 0.1, 0.5, and 1 ppm of N2O standards and 1, 2.5, 5 and 10 ppm of CH4 standards, both curves used pure He as 0 value. The analytical error for N2O measurements was ~3% and ~5% for CH4. CH4 was manually analyzed through a capillary column GS-Q (J&W, 0.53 mm×30 m) and 30°C oven temperature The uncertainty of the measurements was calculated from the standard deviation of the triplicate measurements by depth. Samples with a variation coefficient above 10% were not considered.

title: Chlorophyll pigments and total organic carbon measured during POLARSTERN cruise PS94 (TransArcII) to the Barents Sea and central Arctic

description: Chlorophyll pigments:Subsamples of the top first cm of sediment were obtained using cut-off plastic syringes. Samples for chlorophyll pigment analyses were stored dark and frozen at -20°C until further analyses in the home laboratory. Chlorophyll pigments were extracted as described in Boetius et al. (1998, https://doi.org/10.1016/S0967-0637(97)00052-6). Briefly, pigments were extracted in 90% acetone, after addition of glass beads and grinding in a cell mill. Extracts were centrifuged and concentrations of chlorophyll a and phaeopigments (after acidification with HCl) were determined with a Turner Trilogy fluorometer. The sum of chlorophyll a and phaeopigments is expressed as chloroplast pigment equivalents (CPE). The proportion of chlorophyll a from CPE (% chla) is an indicator of the freshness of phytodetritus.Total organic carbon:Subsamples of the top first cm of sediment were also obtained using cut-off plastic syringes. Samples were stored frozen at -20°C until further analyses in the home laboratory. The total carbon content of sediment samples was determined by combustion and gas chromatography with a Carlo Erba NA-1500 CNS elemental analyzer. An aliquot of the sample was acidified to remove the fraction of inorganic carbon and to determine the total amount of organic carbon.

title: Monosaccharide compositions of oligosaccharides extracted by non-porous graphitised carbon solid phase extraction from filtered seawater collected on cruises MSM107 and EN683 in 2022

description: Water samples were collected with CTD rosette samplers (SeaBird SBE 911Plus) at two depths (deep chlorophyll maximum and bottom water) during two cruises in 2022: the RV Maria S. Merian cruise MSM107 to the western Irish shelf and the RV Endeavor cruise EN683 to the northwest Atlantic. Water was collected at one station during each cruise. Immediately after collection seawater was filtered through a 0.22 µm polyethersulfone filter and oligosaccharides were extracted with Supelclean™ ENVI-Carb™ SPE cartridges (60 mL, 10 g) from 600 mL samples. Processing blanks were also extracted on board using Sigma sea salts dissolved in MilliQ-water. Extracts were acid hydrolysed (1 M HCl, 24 h, 100°C), and the released monosaccharides were derivatised with 1-phenyl-3-methyl-5-pyrazolone (PMP) and quantified by LC-MS/MS (Xu et al., 2018, doi:10.1039/C7AN01530E). Sugar derivatives were separated on a C18 column and detected with a SCIEX qTRAP5500 mass spectrometer in multiple reaction monitoring (MRM) mode. The monosaccharide concentration file contains the calculated concentrations of monosaccharides in samples after normalisation with respect to internal standards, calibration against standard curves and division by the concentration factor. Processing blanks are referred to as having sample type of 'Artificial seawater extract' and seawater extracts as 'Seawater extract'.

title: Whale sightings during POLARSTERN cruise PS82 (ANT-XXIX/9)

description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS82 (Cape Town – Cape Town) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken if possible for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.

title: Sierra Nevada Spain Snow Surface Data at the Ski Area 2024

description: We collected snow surface data on 2024-04-19 at the Sierra Nevada (Spain) ski area focusing on a groomed ski slope and an adjacent, natural (ungroomed) area. We used a 60-cm long snow roughness board and an iPad with the 3-D Scanner app to create two and three dimensional representations of the surface, respectively. The resolution of the snow roughness board and iPad scanning are about 0.2 mm and 1.5 cm. The roughness board is orange with a black edge. At each location, the snow roughness board were inserted into the snow so that the interface of the snow surface was highlighted by the orange of the roughness board. This interface was photographed and the raw snow roughness board are those images. The iPad scanning covered a 2-m wide swath over a 15-meter length. The data are in ASCII format as relative location (X,Y,Z) and colour (R,G,B).
