WCS ST DOM1

Dieser OGC konforme WebCoverageService stellt das Digitale Oberflächenmodell (DOM) bereit. Das Digitale Oberflächenmodell (DOM) beschreibt im Gegensatz zum Digitalen Geländemodell - DGM nicht die Höhe des natürlichen Erdbodens (Gelände), sondern die Höhe der Oberfläche der auf der Erde befindlichen natürlichen und künstlichen Objekte (z. B. Vegetation, Gebäude, Fahrzeuge). Es handelt sich hierbei um ein auf einer Laserscanbefliegung basierendes Situationsmodell. Maßstab: 1:null; Bodenauflösung: 1m; Scanauflösung (DPI): null; Erläuterung zum Fachbezug: WCS Service

ATKIS - DOM1 (2025)

Digitale Oberflächenmodelle (DOM) sind digitale, numerische, auf ein regelmäßiges Raster reduzierte Modelle der Höhen und Formen der Erdoberfläche und der darauf befindlichen Objekte wie z.B. Vegetation und Bauwerke. Sie 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.

Ferrybox underway observations of physical and optical surface water variables during HE626/2 from 2023-10-27 to 2023-11-07

The data presented here were collected during the cruise HE626-2 with RV Heincke from Bremerhaven to Bremerhaven (2023-10-27 to 2023-11-07). The water intake of the autonomous measurement system was in approx. 3 m depth. All data have been subjected to automated quality checks (see processing report) and visual control. The chlorophyll-a data were additionally calibrated by comparison with discrete samples. Details on all quality control steps and the calibration can be found in the data processing report. The resulting data set contains the quality-controlled data and corresponding quality flags. The data set contains data during transect and station. The rawdata are also available on request from the principal investigator.

Colored dissolved organic matter (CDOM) absorption coefficients in the sea-surface microlayer and the underlying water during a mesocosm phytoplankton bloom in 2023

The effects of a phytoplankton bloom and photobleaching on colored dissolved organic matter (CDOM) in the sea-surface microlayer (SML) and the underlying water (ULW) were studied in a month-long mesocosm study, in May and June of 2023, at the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany. The mesocosm study was conducted by the DFG research group BASS (Biogeochemical processes and Air–sea exchange in the Sea-Surface microlayer, Bibi et al., 2025) in the Sea Surface Facility (SURF) of the ICBM. The facility contains an 8 m × 1.5 m × 0.8 m large outdoor basin with a retractable roof, which was closed at night and during rain events. The basin was filled with North Sea water from the adjacent Jade Bay. Homogeneity of the ULW in the basin was achieved by constant mixing of the water column. The daily SML and ULW samples were collected alternating in the morning, about 1 h after sunrise, and in the afternoon, about 10 h after sunrise. The alternation of sampling times intended to capture a potential effect of sun-exposure duration on DOM transformations and elucidated the day and night variability of the layers. The SML was collected via glass plate sampling (Cunliffe and Wurl, 2014). The ULW was sampled via a submerged tube and a connected syringe suction system in 0.4 m depth. The removed sample volume was refilled with Jade Bay water every day. SML and ULW samples were filtered through pre-flushed 0.7 µm Whatman GF/F and 0.2 nucleopore filters into brown bottles and were stored dark and at 4 °C until measurement within weeks of the study. The brown bottles were previously combusted at 500 °C. CDOM was measured with three liquid waveguide capillary cells (LWCC, WPI, USA) of different pathlengths (10 cm, 50 cm, 250 cm) to increase the measurement sensitivity following the protocols of Röttgers et al. (2024) using a spectral detector (Avantes, Netherlands) for a total spectral range from 230 to 750 nm. A sodium chloride (NaCl) solution was used for the salinity correction. The blank-corrected absorbance spectra were then converted into Napierian absorption coefficients (Bricaud et al., 1981).

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.
