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...
In the context of global biodiversity decline, the monitoring and assessment of marine biodiversity have gained increasing importance. Thaliacea, a group of filter-feeding gelatinous zooplankton, play...
Direct observations from submersible dives off the Galapagos Islands have revealed that Pelagothuria natatrix, the only known holopelagic echinoderm, actively intercepts settling particles well before...
In this paper, we present results that have important implications for understanding the sedimentation process and for evaluating the carbon cycle in deep-sea sediment of the southern Gulf of Mexico (...
Carbon fixation in marine ecosystems is a vital process that contributes to climate regulation, with ocean sediments playing a critical role in carbon sequestration. This process is driven by chemolit...
Climate change threatens polar ecosystems through rising temperatures and changing light regimes. Phytoplankton release of dissolved organic carbon (DOC) is a major carbon-cycle component, yet it rema...
Today, the sea ice cover is rapidly declining in the Arctic Ocean. While major changes in the Arctic marine ecosystems are starting to appear, the full implication of a changing Arctic ecosystem is no...
There is a common misconception among ocean scientists and policy makers that mesopelagic (200-1000 m) food webs are an unexploited "final frontier" of living marine resources. It is true that there a...
The ocean carbon cycle spans multiple scales and reservoirs, challenging efforts to build a coherent picture and fostering misconceptions or fragmented narratives in science and public discourse. Comm...
The Gulf Stream is important for the climate system through its transport and air-sea exchange of heat. What is less well accepted is the role of the Gulf Stream in the carbon cycle. Here we examine h...
