Energy policy is often guided by a small set of least-cost pathways to net-zero emissions, despite wide uncertainty in technology performance, fuel prices, demand and weather. To avoid overstating con...
Large Arctic rivers transport substantial amounts of freshwater, carbon (C), and nutrients from land to the Arctic Ocean and play an important role in continental-ocean biogeochemical coupling. Althou...
Deep-sea hydrothermal vents are among the most extreme and geochemically dynamic environments on Earth, characterized by steep gradients in temperature and chemical concentration. Alvinocaridid shrimp...
Ocean acidification (OA) driven by increasing atmospheric CO2 is altering marine biodiversity. However, impacts of OA on ecosystem functioning at the community level, including calcification, primary ...
The deep sea contains a wealth of potential mineral resources, many of which are being investigated for commercial exploitation. Exploration and technical tests started in the late 1970s with an initi...
Vast amounts of munitions dumped in the marine environment, have been reported to leak chemicals due to munition corrosion. The subsequent increased levels of explosives and related chemicals (E&RC), ...
Ocean iron fertilization (OIF) is being discussed as a potential carbon dioxide removal (CDR) strategy1. Yet the trade-offs between climate benefits and ecological costs remain poorly understood2-4. H...
Although sea-ice ridges are prominent features of the Arctic Ocean, very little is known about their role as habitats and in biogeochemical cycles. Here, we show that ridges provide complex sea-ice ha...
Sponges can be considered biological engines that fuel the ecology of shallow-water to deep-sea ecosystems through the sponge loop. Here, we discuss new insights on the role of the sponge holobiont in...
Understanding the acute and longer-term effects of marine heatwaves on coastal ecosystems is critical for predicting their response to future warming. We used a 23-year time series that included two m...
The mesopelagic zone, between 100 and 1000 m depth, contains up to 90% of marine vertebrate biomass. Mesopelagic fishes are key components of these ecosystems through their feeding interactions and pl...
Biomass valorization has become a central strategy in the transition toward a circular bioeconomy, enabling the conversion of underutilized terrestrial and marine resources into value-added functional...
Enzymatic hydrolysis is one of the effective methods used to obtain the bioactive peptides from marine resources. This study aimed to evaluate effect of the enzyme type (Food Pro PNL (FP), Corolase800...
While CO2 fixation by photo- and chemolithoautotrophs is a central process of the global carbon cycle, many organisms also incorporate inorganic carbon into organic compounds through anaplerotic carbo...
Particulate (POC) and dissolved (DOC) organic carbon released during macroalgae cultivation has been shown to lead to carbon burial and export to the open ocean and deep sea. The recalcitrant portion ...
Mesopelagic fishes transport a vast biomass of organic material between surface and deep waters through diel vertical migration (DVM), which plays a crucial role in both food web functioning and deep-...
Microorganisms dominate life in the hadal zone, yet extreme sampling difficulty and low biomass have precluded characterization of their in situ activities. Here, we analyze microbiome samples collect...
Coral reef islands face escalating degradation due to extreme substrate infertility (coral sand) and waste management challenges in isolated marine environments. High-oil food waste composting offers ...
The functioning of high-diversity ecosystems, such as coral reefs, is intrinsically tied to the integrity and efficiency of the trophic pathways within these systems. Coral reef productivity depends, ...
Pollutant transport-reaction dynamics in aquatic systems often exhibit environmental memory, in which the present state depends on antecedent environmental conditions. This study develops a time-fract...
