The planktic foraminifera Neogloboquadrina pachyderma is a calcifying marine protist and
the dominant planktic foraminifera species in the polar oceans, making it a key species in …

The reproductive strategy of planktonic foraminifera, key pelagic calcifiers, has long
remained elusive, hampering efforts to understand and model their population dynamics …

The trophic strategies of cold-water planktonic foraminifera are not well understood due to
the challenge of culturing them in polar conditions. Here, we identify previously unknown …

Deep water freshening beneath pan-Arctic ice shelves has recently been proposed based
on the absence of excess thorium in glacial Arctic sediments. This profound proposal …

Isotopic and trace-element signals in the calcite shells of the planktonic foraminifera
Neogloboquadrina pachyderma represent key proxies to reconstruct past climatic conditions …

The Arctic Ocean is surrounded largely by continents, and the Fram Strait (sill depth 2,500
m) is the only deep connection to the Nordic Seas and further south to the North Atlantic …

The ratio of sodium to calcium in the shells of foraminifera (Na/Cashell) has been
experimentally calibrated as a proxy for past ocean Ca concentrations (Hauzer et al., 2018 …

Foraminifers can be found in all marine ecosystems, from the shallows to the deep oceans.
They are environmentally sensitive and can reflect the health of the habitat in which they …
