bloom Dense population of microscopic algae or cyanobacteria on the surface of lakes or seas, often colouring the water. They may appear suddenly through migration of the population to the water surface. This occurs when the cells (previously mixed down into the water column by wind action) float or swim to the surface under calm conditions. They may arise also through rapid multiplication in response to large increases in nutrients. This happens when sewage, or other mineral-rich water, enters a lake or sea. Some blooms produce toxins, which can be harmful to marine life.

bloom Fat bloom is the whitish appearance on the surface of chocolate which sometimes occurs on storage. It is due either to a change in the form of the fat at the surface or to fat diffusing outwards and being deposited as crystals on the surface. Sugar bloom is less common; it is due to the deposition of sugar crystals on the surface.
