The marine sediment samples collected for assemblage analysis were washed through a\r\n
63 micron sieve in order to retain foraminifera. The >63 micron sample residue was dried then picked through for foraminifera using a reflected light binocular stereomicroscope, to obtain at least 300 specimens per sample to ensure that full diversity within each sample was accounted for (Dennison and Hay, 1967). The picked foraminifera were identified to the species level, using the taxonomic concepts of Igarashi et al., 2001 and Echols, 1971.\r\n
