Abstract

During the spring diatom blooms of 1992 and 1993 in Loch Creran, Scotland, regular water column and sediment samples were collected, examined, and species composition of the phytoplankton determined. Thalassiosira species were found to be a major bloom constituent. Species were identified from specimens cultured from sediments and isolated from vertical net hauls, using light and scanning electron microscopy. Of the 17 species positively determined, only Thalassiosira angulata, T. anguste-lineata, T. eccentrica, T. gravida, T. minima, T. nordenskioeldii, T. rotula and T. tenera have been previously reported in Scottish waters. Other species, for example Thalassiosira pseudonana and T. punctigera, have been noted elsewhere in the British Isles but not along the Scottish west coast. Several species, namely Thalassiosira concaviuscula, T. constricta, T. delicatula, T. kuschirensis, T. oceanica, T. pacifica and T. tealata, are new records for the British Isles. One unidentified taxon is illustrated. Descriptions, illustrations and a key are provided for the 18 taxa.
