Article
Compared to the widespread occurrence of Paleodictyon in the geological record, in situ observations of this trace (herein termed ‘pattern’) in modern deep-sea sediments are still scarce, being confined to the Mid Atlantic Ridge, the South Atlantic, southwestern Pacific and the eastern equatorial Pacific Clarion-Clipperton Zone. Here, we report the...

Background The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of...
Article
A new species of eelpout genus Pachycara Zugmayer, 1911 is described based on five specimens caught at a depth of 2419–3275 m along the Central and Southeast Indian Ridges in the Indian Ocean. The specimens were collected during the INDEX cruises in 2016, 2018 and 2019, respectively. The new species is distinguished from its congeners by the follow...
Article
Active hydrothermal vents are small-scale habitats hosting endemic fauna in a well-defined zonation around fluid effluents. The fauna of inactive hydrothermal vents and its relation to active vents and non-vent area is poorly known. Characterizing inactive areas is prerequisite to establish protected areas, especially in the context of potential se...

Active hydrothermal vent fields are complex, small-scale habitats hosting endemic fauna that changes at scales of centimeters, influenced by topographical variables. In previous studies, it has been shown that the distance to hydrothermal fluids is also a major structuring factor. Imagery analysis based on two dimensional photo stitching revealed i...
Article
The Wadden Sea is a highly productive coastal ecosystem and an important nursery ground for various demersal fishes of the southern North Sea. Copepods are one of the major food sources of the ecosystem, yet little is known about the movement patterns of this benthic meiofaunal group within both sediment and water column in the intertidal environme...

Here we present a chimney within the newly dis-covered hydrothermal vent field “Pelagia”. Videos were collected during the Indian Ocean Exploration Project of the Federal Institute for Geosciences and Natural Resources (BGR) within the German license area at the southwestern Central Indian Ridge. For mosaicking, annotation and 3d modelling the ROV...
