Abundance, encystment and sedimentation of acantharia during Autumn in the East Greenland Sea
The abundance and sedimentation of acantharia and their cysts was recorded in the water column and sediment traps in the East Greenland Sea in August-September 1990. Although acantharia constituted <1% of total suspended particulate organic carbon (POC) in the water column, up to 90% (average 55%...

The abundance and sedimentation of acantharia and their cysts was recorded in the water column and sediment traps in the East Greenland Sea in August-September 1990.

Rapid dissolution of strontium sulphate, of which their shells and spines are constructed, was evidenced by their disappearance with depth in the water column, maximum dissolution occurring between 500 and 1000 m water depth. Mass encystment and sedimentation of this single group of sarcodine protozoa can have dramatic effects on, the measurement of particulate fluxes in the open ocean, and may be a recurrent phenomenon in the eastern North Atlantic. |
