Quotation Marks: Spring Bloom, Long Island Sound
Diatoms are the estuary's basic food crop. They thrive in coastal areas, where winds keep the surface waters well-mixed, helping to give the diatoms the sun's full benefit by suspending them near the top. Diatoms come in many shapes--some are bladder-like or needle-like, some like discs or subtly curving worms. In February, fed by the grasses and stimulated by increasing sunlight, the diatoms and other phytoplankton (a survey once found one hundred and twenty-five species in Long Island Sound) reproduce at a tremendous rate. The diatoms can double in number every day. More than forty million individual phytoplankton cells may cram into three cubic feet of water; eighty cubic feet may hold a billion individual plants.
