En av de största diatom databaserna finns nu på webben. .. "Researchers can now access one of the largest diatom databases on the Internet. With a current size of approximately 300,000 preserved samples and 80,000 microscope slide preparations, the collection is invaluable for science. Diatoms are unicellular photosynthetic organisms that occur both in marine and in freshwater environments. They are an important part of the food chain, and represent useful indicators for ecological and climatic change. Their unique feature is a cell wall constructed of silicate organized in a characteristic structure. Diatoms are classified according to this structural pattern of the walls."
