Short term dynamics of planktonic foraminiferal sedimentation in the porcupine seabight
Modern planktonic foraminifera collected with a sediment trap, and subfossil assemblages from surface sediments from the Galway, Mound in the Porcupine Seabight off southwestern Ireland, (northeastern Atlantic), were studied in order to investigate recent assemblage variations. The sediment trap ope...
