Botany Bay is located within the Sydney metropolitan area - the largest of the Australian cities and located on the eastern coast of New South Wales, Australia. The bay is fed by two rivers, the Cooks River and the Georges River. The maximal tidal range in the bay is about 2 metres. The natural intertidal shoreline of Botany Bay consists of three main habitats: rocky areas, soft sediments (sandy beaches and mudflats) without macroalgae or other large plants, and vegetated soft sediments (mangrove swamps and seagrass beds). Dinoflagellates were collected in sediment taken from intertidal regions from 1998 - 2002. The picture of the landing by Cook at Botany Bay in 1770 we think shows Cook and Bates exchanging views in a lively fashion as to the best place to collect dinoflagellates. This picture was painted by E Phillips Fox in the early part of the 20th century.
