Abstract
This note describes results of sampling the microplankton (pelagic protists including algae and protozoa) in loch Creran during 2012 and compares
seasonal patterns of abundance with those in 1979-1981. There is no longer a
Spring Bloom of the diatom Skeletonema, and agellates and dinoflagellates are
more numerous. However, signicant change in biomass could not be demonstrated
either by statistical analysis of the seasonal graphs or using the Phytoplankton
Community Index (PCI). Methods used for microscopy and numerical analysis are discussed, including the problems caused by low cell counts. A small
improvement in the fitting of the PCI envelope is reported.
