A method for preparing permanent mounts of phytoplankton for critical microscopy and cell counting. Limnol. Oceanogr., 26(5):976-980. Preserved phytoplankton are settled onto cover glasses, dehydrated by ethanol vapor substitution, and mounted in ethanol-soluble resin. Resulting slides are permanent, quantitative, and of excellent optical quality; with the appropriate resin, contrast is high enough to eliminate the need for enhancement.
