Production, preservation and sedimentational aspects of common marine copepod fecal pellets were studied in order to understand the transport of organic and inorganic material from the surface to the deep sea. Fecal pellets were obtained from laboratory cultures of Calanus finmarchicus, Acartia tonsa and A. clausi fed several species of coccolithophores (approximately 10 µm in diameter) and diatoms (approximately 6 µm and 50 µm in diameter)....
