Species abundance: R = rare; S = sparse; F = frequent; C = common; A = abundant; lower-case abundance designators are interpreted as reworked occurrences.

Relatively high opal concentrations are measured in equatorial Atlantic sediments from the most recent deglaciation. To shed light on their causes, seven cores were analyzed for...

During the Indian Ocean Expedition of R/V METEOR phytoplankton samples were taken with a multiple closing net (Multinet) at 103 stations. In this material the diatoms were...
