Glacial rock flour increases photosynthesis and biomass of natural phytoplankton communities in subtropical surface waters: a potential means of action for marine CO2 removal

Autor: Jørgen Bendtsen, Niels Daugbjerg, Jørgen L. S. Hansen

Publikováno v: Frontiers in Marine Science, Vol 11 (2024)

Photosynthesis by phytoplankton reduces partial pressure of CO2 at the surface of the ocean and is therefore a potential means of action for a marine CO2 removal technology. Here we study how glacial rock flour may influence photosynthesis in the ope

Primary production in the North Atlantic estimated from in situ water column data observed by Argo floats and remote sensing

Publikováno v: Frontiers in Marine Science, Vol 10 (2023)

Combining information on the vertical distribution of nutrients and remote sensing can potentially improve estimates of ocean primary production (PP). Here, we employ in situ observations of chlorophyll a and nitrate from biogeochemical Argo floats d

Abstract The supply of freshwater to fjord systems in Greenland is increasing as a result of climate change-induced acceleration in ice sheet melt. However, insight into the marine implications of the melt water is impaired by lack of observations de

An updated view on water masses on the Northeast Greenland shelf and their link to the Laptev Sea and Lena River

The Northeast Greenland shelf is a broad Arctic shelf located between Greenland and Fram Strait. It is the principal gateway for sea ice export and sea ice-associated freshwater from the Arctic Ocean. Sea ice thickness has decreased by 15% per decade

Greenland's fjords and coastal waters are highly productive and sustain important fisheries. However, retreating glaciers and increasing meltwater are changing fjord circulation and biogeochemistry , which may threaten future productivity. The freshe
