A Global Dataset of Bathymetric Features Identified with Prominence and Isobaths Analysis

This dataset comprises 125,514 submarine bathymetric features derived from the GEBCO_2025 Grid at 15 arc-second resolution (GEBCO Compilation Group, 2025) through computational analysis. Features were identified globally (excluding land areas) using topographic prominence calculation based on the algorithm of Kirmse and de Ferranti (2017), and characterized via isobath analysis. Each feature with prominence ≥300 m is represented as a polygon geometry with five nested contour levels (100%, 90%, 75%, 50%, and 25% from base to peak prominence level) and morphometric attributes including area, circularity, orientation, bounding box dimensions, and slope statistics. A companion point dataset contains all 143,888 detected peaks, including those rejected during quality control. The dataset provides an objective, reproducible global inventory of submarine features for research in marine geology, biodiversity, oeanography, and resource assessment. The attribute-rich structure enables users to define sub-classifications using standard SQL queries (e.g., filtering for seamounts using prominence ≥1000 m and circularity criteria). Data are distributed as OGC-compliant GeoPackage files. Processing was performed in 2025.

OBS stations of the GEOSTOR project in the German Bight and in the German Baltic Sea (WMS)

The dataset includes the locations of OBS stations (Ocean Bottom Seismometers) operated in the German Bight during cruise MSM100 with R.V. Maria S. Merian. The time interval from 13.05.2021 to 15.05.2021 has been analysed in a phase without airgun operation for passive recording with 4.5 Hz geophones. Furthermore, the dataset contains locations of 3 broadband OBS systems which were operated during an experiment at the Darss ramp in the German Baltic Sea. The records were analysed in the time interval 23.01.2018 to 01.04.2018.

Processed seismic data of Cruise MSM14/2 2010

The initial study area of the cruise MSM14/2 GeoNORM (Geophysik im noerdlichen Roten Meer) was the northern Red Sea. However, because of not given research permissions from Egypt and Saudi Arabia, the study area had to be changed to the alternative study area Eratosthenes Seamount (ESM), south of Cyprus. The ESM is supposed to represent a continental fragment of the former African-Arabian Plate that is entering the subduction zone south of Cyprus i.e. the subduction turns into collision in the area of the ESM. This changed the entire tectonic setting in the Eastern Mediterranean. Therefore, the tectonic evolution of the area is rather complex with phases of extension, subduction, compression, salt tectonics and gravitational processes and not comprehensively understood. Because of the isolation of the ESM as a continental fragment this region is an ideal spot to investigate the transition from regular subduction to continental collision and its associated tectonic processes i.e. faults were activated or reactivated, transform motion has to be compensated, the overriding plate has been elevated. This impacts the ongoing geological and tectonic processes in this region but also influences the social and economic life in the Eastern Mediterranean as earthquakes and submarine landslides are possible geohazards and the entering of the ESM to the subduction trench alters the thermal history of the adjacent sedimentary basins significantly what should have an influence on the maturity processes within the source rock sediments and new faults open new migration paths for hydrocarbon fluids or gases.

Ce programme s'integre au programme general de surveillance coordonne par l'Agence de l'Energie Nucleaire de l'OCDE. Trois campagnes ont ete realisees en 1982 et 1983. Les donnees obtenues sont actuellement integrees a un modele de resuspension et de circulation a petite echelle, developpe a l'Universite de Harvard. (FRA)

EasyGSH-DB: Morphologischer Raum (1996-2016)

Definition: Der morphologische Raum ist der Betrag der Differenz zwischen maximaler und minimaler Höhe eines Ortes über den Verlauf mehrerer Zeitschritte. Er kann genutzt werden, um morphologisch stabile Bereiche zu identifizieren, die zum Beispiel als potentielle Gebiete für Bauprojekte in Betracht kommen. Datenerzeugung: Die Basis für bathymetrische Produkte bilden gerasterte bathymetrische Modelle, die mithilfe des Funktionalen Bodenmodells, einem datenbasierten hindcast-Simulationsmodell, über räumlich-zeitliche Interpolationsverfahren aus einer Datenbasis von See- und Landvermessungen verschiedenster Datentypen erstellt werden. Für jedes Jahr von 1996 bis inklusive 2016 wird ein gerastertes bathymetrisches Modell in 10 m Auflösung für die Deutsche Bucht und zusätzlich in 250 m Auflösung für die Ausschließliche Wirtschaftszone für das Jahr 1996 erstellt. Für die Deutsche Bucht wird der morphologische Raum für jeden Rasterknoten berechnet, indem aus den bathymetrischen Modellen der jeweils höchste und niedrigste z-Wert über 21 Jahre Betrachtungsraum ermittelt und die Differenz zmax-zmin gebildet wird. Die maximale Spannweite der Gewässerbodenhöhe wird an jedem Punkt dargestellt. Da es sich um eine Auswertung mehrerer Zeitschritte handelt, ist der morphologische Raum nicht für die Ausschließliche Wirtschaftszone ermittelbar. Produkt: 10 m Raster der Deutschen Bucht, wobei an jedem Rasterknoten der Betrag des morphologischen Raums über den Zeitraum 1996 bis 2016 abgelegt ist. Das Produkt wird im GeoTiff-Format bereitgestellt. Zitat für diesen Datensatz (Daten DOI): Sievers, J., Rubel, M., Milbradt, P. (2020): EasyGSH-DB: Themengebiet - Geomorphologie.

Processed seismic data of Cruise BGR15-2 2015 (PANORAMA-2)

The PANORAMA-2 research cruise was carried out between August 15th and September 20th 2015 aboard the Italian research vessel OGS Explora, like the PANORAMA-1 cruise in 2013. The intended survey area was the European sector of the Arctic east and southeast of the Svalbard archipelago in the area of the northern Barents Sea. Main target of the PANORAMA-2 cruise was the acquisition of new geophysical data and the probing of surficial sediments in the underexplored area of the Sørkapp Basin and Olga Basin. In the course of the 20 day lasting Leg1 of the PANORAMA-2 cruise geophysical data acquisition was carried out. About 1750 km of 2D multi-channel seismic data were acquired and about 350 km of wide angle seismic data by means of sonobuoys. Sediment echosounder data, multi-beam data, gravity data and geomagnetic data were acquired during the entire cruise in a 24/7 mode within the survey area. After a 1-day stopover in Longyearbyen for a crew change of a part of the scientific crew, the research vessel OGS Explora returned to the survey area for another 11 days. During Leg-2 of the PANORAMA-2 cruise the surficial sediments were sampled by means of gravity corer, multi corer and dredge at 34 stations all together. Sediment sampling was carried out during day-light times only. Night times were used for acquisition of geomagnetic data, gravity data, sediment echosounder data and multi-beam data.

INSPIRE: Marine seismic survey profiles for the German EEZ (MSSP-EEZ)

During the period from 1996 to 2007 five cruises operated by BGR acquired seismic lines from the German EEZ. The aim of these expeditions was a detailed survey of the geological structure of the seabed from the North Sea and Baltic Sea. The five GML files (for each cruise one) together with a Readme.txt file are provided in ZIP format (MSSP-EEZ-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements.
