Planktonic foraminiferal abundance and flux in the Porcupine Seabight, Northeast Atlantic
Modern planktonic foraminifera collected with a sediment trap and subfossil assemblages from surface sediments from Galway Mound in the Porcupine Seabight off southwestern Ireland, northeastern Atlantic, were studied to show recent assemblage variations. The sediment trap operated from April to Augu...
