Impact of Local Iron Enrichment on the Small Benthic Biota in the deep Arctic Ocean The study assesses the impact of local iron enrichment on the small benthic biota (bacteria,...

Undisturbed sediment samples were obtained with a TV-guided multiple corer (TV-MUC). Upon retrieval of the MUC, the overlying water was carefully removed from each core and the...

The data set reports organic carbon (TOC), total carbon (TC), total nitrogen (TN), and total sulfur (TS) concentrations in the upper horizons of deep-sea sediments. The data can...

The data set reports phytopigment concentrations in the upper horizons of deep-sea sediments. Chlorophyll a (Chl a) represents the most fresh and labile part of the...

This dataset contains raw counts of individual nodule-crevice fauna assigned to higher taxonomic groups: Nematoda, Copepoda, Polychaeta, Tardigrada, Tanaidacea, Kinorhyncha,...

This dataset contains information on Arctic deep-sea nematode genus body size, biomass, feeding types, tail shapes and cp-values (years 2010, 2014 and 2019). Sampling was...

This dataset contains information on Arctic deep-sea nematode abundance calculated for 10 cm² of seafloor on genus level (time period 2000 to 2009), as well as counts (years...

Here, we examine the ecosystem ramifications of changes in sediment-dwelling invertebrate bioturbation behaviour—a key process mediating nutrient cycling—associated with...

We present sediment data from cores collected at bathyal and abyssal depths (1960–5337 m) along a 2400-km North–South transect in the Atlantic part of the Southern Ocean. During...

Oxygen microprofiles were measured using an autonomous benthic lander system. Once the lander had stabilized at the seabed, an array of O2 microelectrodes was vertically moved...

Carbon export (from the epipelagic towards the mesopelagic zone) and sequestration (from the mesopelagic towards the bathypelagic zone) in the ocean are reviewed. Particulate...

The Deep-sea Sponge Microbiome Project is a large-scale study, integrating 16S amplicon sequencing data with oceanographic data. The present dataset contains 66 full water...

The Deep-sea Sponge Microbiome Project is a large-scale study, integrating 16S amplicon sequencing data of seawater, sediment, and sponges, with a large set of ecological and...

Obtaining a comprehensive knowledge of the spatial variation of deep-sea benthic ecosystems is essential for conservation and management purposes. Here we assembled publicly...

Cold-water corals are important bioengineers that provide structural habitat for a diverse species community. About 70 % of the presently known scleractinian cold-water corals...

Ocean acidification, the decrease in seawater pH due to the absorption of atmospheric CO2, profoundly threatens the survival of a large number of marine species. Cold-water...

While ocean acidification is a global issue, the severity of ecosystem effects is likely to vary considerably at regional scales. The lack of understanding of how...
