WMS SL GDI Oberflächenmodelle - DOM Shaded Relief (2016)

Oberflächenmodelle Saarland:Ein DOM ist ein Digitales Höhenmodell, das im freien Gelände dem DGM entspricht, also die natürliche Geländeoberfläche abbildet, ansonsten aber über die Oberflächen der Gebäude und der beständigen Vegetation verläuft. Datengrundlage sind die durch Laserscanning gewonnen dreidimensionalen Messpunkte. DOM bilden die Situation zum Zeitpunkt der Erfassung ab. Bedingt durch unterschiedliche Erfassungszeitpunkte können z.B. bei Vegetations- und Wasserflächen Höhensprünge auftreten. Hohe schmale Objekte wie bspw. Windräder und Strommasten können nur bedingt abgebildet werden.

Molecular and elemental composition of dissolved organic matter in anoxic basins (Mariager Fjord, Denmark; Gotland Basin, Baltic Sea; Black Sea)

The sampling campaigns were conducted in the Black Sea (POS539), Baltic Sea/Gotland Basin (EMB324), and on a boat in Denmark/Mariager Fjord. All three study sites are differently influenced by ocean deoxygenation and anoxia. While Mariager Fjord waters are seasonally anoxic, the deep waters of Gotland Basin and Black Sea can remain anoxic for decades and millennia, respectively. Furthermore, to target potential abiotic reactions, we incubated filtered Gotland Basin waters at low (<1.5µM O2) and high (>200µM O2) oxygen concentrations. All samples were filtered to 0.2 µm pore size and acidified with hydrochloric acid to pH2. DOM was extracted and desalted prior to molecular analysis with ultrahigh resolution mass spectrometry (FT-ICR-MS) following an established method using cartridges filled with a styrene-divinylbenzene copolymer (Agilent Bond Elut PPL, 1 g). This data set contains two files: (1) environmental data, including oxygen concentrations, salinity, temperature, dissolved and solid-phase extractable dissolved carbon (DOC, SPE-DOC), nitrogen (TDN, SPE-DON), sulfur (SPE-DOS), and phosphorus (SPE-DOP), and (2) processed FT-ICR-MS data for all samples.

Environmental parameters, including dissolved organic carbon and molecular indices derived from ultra-high-resolution mass spectrometry (FT-ICR-MS) and infrared spectroscopy (ATR-FTIR)

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a multidisciplinary mesocosm study at the Sea sURface Facility (SURF) of the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany (53.5148 °N, 8.1463 °E). The study was conducted from 18 May to 16 June 2023 as part of the BASS research unit (Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer). This dataset contains environmental data, including dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and DOM molecular indices (MLBwL, Ibio, Iphoto, IDEG) calculated from ultrahigh-resolution mass spectrometry data (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS). Furthermore, we present attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) data from representative samples for each bloom phase. General metadata from the multidisciplinary mesocosm study, including temperature, salinity and chlorophyll a, are provided in Bibi et al. on PANGAEA at the following link: doi:10.1594/PANGAEA.984101.

DOMWSV - Digitale Oberflächenmodelle (DOMWSV00)

Digitale Oberflächenmodelle (DOM) beschreiben neben der nätürlichen Geländeform auch die Oberfläche aller auf der Erdoberfläche befindlichen Objekte durch die räumlichen Koordinaten einer repräsentativen Menge von unregelmäßig angeordneten Oberflächenpunkten. Die DOM-Daten liegen im XYZ-Datenformat (ASCII) vor und sind blockweise im Blattschnitt der Deutschen Grundkarte 1:5.000 zusammengefaßt. Sie haben eine Kachelgröße von 2 km x 2 km. Die geometrische Genauigkeit liegt bei +/- 0,25 m in der Lage (XY) und +/- 0,10m in der Höhe (Z). Das Datenvolumen der XYZ-Datei (ASCII) beträgt abhängig von der Punktdichte (DOM-00) zwischen 1-80 MB pro Block.

Dissolved organic matter (DOM) dynamics obtained through ultra-high resolution mass spectrometry (FT-ICR-MS) in the anoxic basin Mariager Fjord, Gotland Basin, and Black Sea

We studied dissolved organic matter (DOM) dynamics in the anoxic basin Mariager Fjord, Gotland Basin, and Black Sea. Therefore, we performed a mass spectrometric analysis of DOM extracts via FT-ICR MS on a 15 Tesla solariX XR Fourier-transform ion cyclotron resonance mass spectrometer (Bruker Daltonik GmbH, Bremen, Germany). The system was equipped with an electrospray ionization source (ESI, Bruker Apollo II) applied in negative ionization mode. Methanol extracts were mixed with ultrapure water (50:50 v/v) for FT-ICR MS analysis and diluted to a final DOC concentration of 2.5 mg C/L. 200 single scans with an ion accumulation time of 0.1 s were recorded over a mass range of m/z 100 to 1,000 Da and added to one spectrum. Data processing, molecular formula assignments, and compound category classifications were done with the software pipeline ICBM-OCEAN. All sample data was normalized to the intensity sum of 1. FT-ICR-MS data from Mariager Fjord (Denmark), Gotland Basin (Baltic Sea), Black Sea, and an abiotic (de)oxygenation experiment are provided. The data consists of the molecular formula with corresponding m/z measured at an FT-ICR-MS and relative intensities for each sample of these molecular formulas. Additionally, we included common molecular parameters, including H/C, O/C and S/C ratios for each molecular formula.

Dissolved organic matter composition in the sea surface microlayer during a Mesocosm study in Wilhelmshaven, Germany (FT-ICR-MS and ATR-FTIR), spring 2023

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a mesocosm study at the Sea sURface Facility (SURF) of the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany (53.5148 °N, 8.1463 °E). The study was conducted from 18 May to 16 June 2023 as part of the multidisciplinary BASS research unit (Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer). SURF was filled with pretreated natural seawater from the nearby Jade Bay (53° 28' 42'' N, 8° 12' 15'' E) to replicate natural conditions. We selected this approach to examine the regrowth of surviving phytoplankton cells after the initial water treatments, simulating a native microbial community starting with almost no bioproduction or pre-existing bioproduction products. To induce and maintain the phytoplankton bloom, inorganic nitrogen, phosphorus, and silicate were added on May 26, May 31, and June 01, 2023. By that, we induced an algal bloom of Emiliania huxleyi and Cylindrotheca closterium. Water samples were collected using a glass plate for the SML and a tube at 40 cm depth for the underlying water (ULW). This dataset contains DOM molecular data from ultrahigh-resolution mass spectrometry (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS), molecular indices calculated from FT-ICR-MS data (Ibio, Iphoto, IDEG) and environmental data, including dissolved organic carbon (DOC) and dissolved organic nitrogen (DON). Furthermore, it contains attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) data from representative samples for each bloom phase. By combining molecular analyses with nutrient and bloom-phase data, we highlight the in situ production of carbohydrate-like and laminarin-derived DOM as a significant contributor to SML composition. General metadata from the multidisciplinary mesocosm study, including temperature, salinity and chlorophyll a, are provided in Bibi et al. on PANGAEA at the following link: doi:10.1594/PANGAEA.984101.

Digital surface model of the watercourses Elbe and Lower Havel (Germany), DGM-W Elbe project, DOM Elbe 2022

The high-resolution digital surface model (DSM1, DOM1) of the watercourses Elbe and Lower Havel is based on the airborne laser scanning data, undertaken from 06 January 2022 to 18 March 2022 in the Elbe area and from 20 to 22 December 2021 in the Havel area. It was produced and published by Germany’s Federal Institute of Hydrology (BfG), on behalf of the River Basin Community Elbe (RBC Elbe, FGG Elbe). The work was supported by the German Federal Waterways and Shipping Administration (WSV) and the surveying offices and water management administrations of six German states - Saxony, Saxony-Anhalt, Brandenburg, Lower Saxony, Mecklenburg-Vorpommern and Schleswig-Holstein. The data cover both the area around the inland water stretches of the Elbe from the Czech-German border to the village of Zollenspieker (part of the city of Hamburg) and the Lower Havel waterway from the town of Rathenow to its confluence with the Elbe. Since the dataset has a large coverage of 4,043 km², it is split into 62 sections. They were either labelled *HW in case of flood relevant areas (in German: “hochwasser-relevante Gebiete”) or *AU in case of historical floodplains (in German: “Altauengebiete”). Financing was divided according to these categories: In the HW areas, the project was co-funded by BfG, the WSV and the federal states, while in the AU areas, BfG covered all project costs. For each section we provide hillshade (*HS) and height maps (*NHN). The data are available in a raster resolution of 1 meter in GeoTiff format; Coordinate reference frame: ETRS89.DREF91.R16; Coordinate projection: UTM Zone 33N; EPSG-Code: 25833; Height reference system: DHHN2016, national vertical reference frame in Germany (2022).
