Data from a long-term culture system for deep-sea mussels Gigantides childres...
Data of culturing two batches of G. childressi specimens for altogether 36 and 27 months, respectively. The deep-sea mussels of the first batch (208 specimens, "batch 1") were... -
Occurrences and measurements of Madrepora oculata cold-water coral colonies o...
Occurence data and measurements of alive vs. dead colony sections of Madrepora oculata cold-water corals were obtained at six coral mounds off Angola from 17th to 25th January... -
Isotope data of deep sea fauna, organic matter and sediment of a sponge groun...
Sponge grounds are hotspots of biomass and biodiversity in the otherwise barren deep sea. It remains unknown how these ecosystems can thrive in such food limited environments,... -
Estimation growth rates of deep-sea squids via increment validation and quant...
We test the hypothesis that deep-sea squid show increased longevity and reduced growth rates compared to coastal and epipelagic species, by validation experiments and... -
Video observations with ROV on feeding associations between two species of Go...
The data consists of analyzed biological information (predator, prey and in some cases relative size), that was visible on the analyzed video as well as video collection data... -
Hydrogen consumption in vent files of the equatorial Atlantic
The discovery of deep-sea hydrothermal vents in 1977 revolutionized our understanding of the energy sources that fuel primary productivity on Earth. Hydrothermal vent ecosystems... -
A new genus Abyssogena from deep-water vents and seeps
A new genus Abyssogena is established for A. phaseoliformis (Métivier, Okutani & Ohta, 1986) and A. kaikoi (Okutani & Métivier, 1986), which were previously assigned to... -
Multibeam and seismic survey, physical oceanography, and sea-bottom videos fr...
We report the northernmost and deepest known occurrence of deep-water pycnodontine oysters, based on two surveys along the French Atlantic continental margin to the La Chapelle... -
Sedimentology and age determination of sediment cores from the Penmarch'h and...
In 1948, Le Danois reported for the first time the occurrence of living cold-water coral reefs, the so-called "massifs coralliens", along the European Atlantic continental... -
Trace element geochemistry of zircons frim in situ ocean lithoshere
We characterize the textural and geochemical features of ocean crustal zircon recovered from plagiogranite, evolved gabbro, and metamorphosed ultramafic host-rocks collected... -
U/Th systematics of authigenic carbonates and δ¹⁸O records from Hydrate Ridge...
Uranium (U) concentrations and activity ratios (d234U) of authigenic carbonates are sensitive recorders of different fluid compositions at submarine seeps of hydrocarbon-rich... -
In situ measurements of hydrogen sulfide, oxygen, and temperature in diffuse ...
The Logatchev hydrothermal vent field (14°45'N, Mid-Atlantic Ridge) is located in a ridge segment characterized by mantle-derived ultramafic outcrops. Compared to basalt-hosted... -
Rare earth element concentrations and geochemistry of carbonate minerals from...
The ultramafic-hosted Logatchev Hydrothermal Field (LHF) at 15°N on the Mid-Atlantic Ridge and the Arctic Gakkel Ridge (GR) feature carbonate precipitates (aragonite, calcite,... -
(Appendix 1-4) Geochemistry, desorption methods, TOC, TC, and mineral content...
Sorption of volatile hydrocarbon gases (VHCs) to marine sediments is a recognized phenomenon that has been investigated in the context of petroleum exploration. However, little... -
Gas analysis of sediment cores from the Batumi seep area
Detailed knowledge of the extent of post-genetic modifications affecting shallow submarine hydrocarbons fueled from the deep subsurface is fundamental for evaluating source and... -
Lipids and nitrogen isotopes of deep-water corals
The lipid and organic nitrogen isotopic (delta15N) compositions of two common deep-water corals (Lophelia pertusa and Madrepora oculata) collected from selected locations of the... -
Pore-water concentration of chloride in sediment cores and equilibrium temper...
Vodyanitskii mud volcano is located at a depth of about 2070 m in the Sorokin Trough, Black sea. It is a 500-m wide and 20-m high cone surrounded by a depression, which is... -
Fluid compositions and mineralogy of precipitates from Mid Atlantic Ridge hyd...
The effect of volcanic activity on submarine hydrothermal systems has been well documented along fast- and intermediate-spreading centers but not from slow-spreading ridges.... -
Sea bed photographs of the Remote Operated Vehicle SPRINT from the shelf west...
This dataset presents sea bed photographs from the shelf west of Spitzbergen along 25 profiles during cruise Heincke 153. ROV (sprint 103) equiped with 36mm still camera; Kodak... -
Fraction of spectral solar radiance transmitted through snow and sea ice as m...
Transmitted solar radiance was measured using an ARC (Advanced-Radiance-Collector) RAMSES hyper-spectral radiometer (TriOS) mounted on the ROV during the ARTofMELT2023...
