Recent Science Highlights

Looking for easy data access to high quality time-series data? SPOTS is out!

Whether we aim to disentangle anthropogenic driven trends from naturally variability or we want to assess and improve our ocean model’s capabilities to correctly display changes in time, all require high-quality observational data from multiple fixed time-series data. Until now access to these data was difficult, time-consuming, and often required solving multiple data challenges before […]

Mixotrophs in the northern North Atlantic

Mixotrophs (or mixoplankton) are now accepted as a third group of plankton alongside phytoplankton and zooplankton. Our knowledge of mixotrophs lags far behind that of the other two groups. We currently have only a limited understanding of mixotrophs’ biogeographical distribution across ocean basins, and what environmental factors are associated with their distribution. The authors of […]

Carbon sequestration by the biological pump is not exclusive to the deep ocean

The biological carbon pump plays a key role in ocean carbon sequestration by transporting organic carbon from the upper ocean to deeper waters via three broad processes: the sinking of organic particles, vertical migration of organisms, and physical mixing. Most studies assume that century-scale carbon sequestration occurs only in the deep ocean, thus have missed […]

Turbulent Mixing: A Dominant Source of Oxygen in the Upper Equatorial Pacific

What balances oxygen removal in the equatorial Pacific? For a long time, oxygen in the eastern and central tropical Pacific was assumed to be mainly supplied by the large-scale advection of remotely ventilated waters via the equatorial current system and meridional circulation. A recent study used an eddy-resolving simulation of a global ocean model to […]

Tiny parasites, big impact: Species networks and carbon recycling in an oligotrophic ocean

Parasites are everywhere in the ocean. Including the microbial realm where a diverse, widespread group of protist parasites (Syndiniales) infect and kill a range of hosts, such as dinoflagellates, radiolarians, and even larger zooplankton. A complete Syndiniales infection cycle is only 2-3 days. First, the parasite is a free-living spore. Once inside a host, the […]

Coastal DOM database – CoastDOM v1

We present the first edition of a global database (CoastDOM v1) and a resulting data manuscript, which compiles previously published and unpublished measurements of DOC, DON, and DOP in coastal waters, consisting of 62,338 (DOC), 20,356 (DON), and 13,533 (DOP) data points, respectively. CoastDOM v1 includes observations of concentrations from all continents between 1978 and […]
