Phytoplankton are probably the most important aquatic organisms that you have NEVER seen! Phytoplankton are nearly invisible and use sunlight, carbon dioxide, and nutrients in water to produce sugars that power the estuary food web. The amount of phytoplankton growth is important because phytoplankton are the food for aquatic animals like zooplankton and fish. Scientists working in the San Francisco Estuary are concerned because phytoplankton growth is low, and some animals are starved for food. Measuring phytoplankton growth is hard because growth is low and the conditions in the water that control growth change quickly. As a result, scientists created a mathematical equation, called a model, that brings together the number of phytoplankton available to grow, the amount of sunlight, and the muddiness of the water to estimate phytoplankton growth each day. This way, scientists can determine where and when food is available to power life in the San Francisco Estuary.

Laser Effect

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.

The advent of the scanning electron microscope (SCEM) has renewed interest in preparing specimens by avoiding the forces of surface tension. The present method of freeze drying by Boyde and Barger (1969) and Small and Marszalek (1969) does prevent surface tension but ice crystal formation and time required for pumping out the specimen to dryness has discouraged us. We believe an attractive alternative to freeze drying is the critical point method originated by Anderson (1951; for electron microscopy. He avoided surface tension effects during drying by first exchanging the specimen water with alcohol, amy L acetate and then with carbon dioxide. He then selected a specific temperature (36.5°C) and pressure (72 Atm.) at which carbon dioxide would pass from the liquid to the gaseous phase without the effect of surface tension This combination of temperature and, pressure is known as the "critical point" of the Liquid.
