MICROSCOPE FOR USE UNDER WATER

1. The first microscope which can be used below the surface of the sea has been devised by scientists at the California University at Santa Barbara. They plan to use it to study marine organisms in their natural environment, and hope that this will prove useful in their work on commercial cultivation of marine life, and in observing the effects of pollution on sea plants and creatures.

2. Dr. M. Neushul, Dr. А С. Charters and Mr. B. Coon designed the microscope, which was built by Mr. N. Lammer at the University's Marine Laboratory. The new system is а development of the conventional dipping cone microscope, which is designed to operate under the surface of water, so that aquatic life can be studied in the laboratory. The microscope itself is almost entirely enclosed in a transparent plastic box. Controls, operated through watertight apertures, as in some underwater cameras, and a battery housed separately to supply power for the microscope light, complete the system.

3. It is even possible to take microphotographs using this equipment, and, as Dr. Neushul points out, "there is really no substitute for direct observation of plants and animals in their natural habitat". The research which will be aided by the new microscope is as interesting as the tool itself. The university scientists have developed a programme to explore the commercial potential of cultivated seaweed to the point where they are planting their own seaweeds in one of the world's first "marine farms".

4. Even the largest of marine plants begin life as microscopically small spores. So a new window has been opened on the reproduction and growth of these plants, during the critical early stages of their development.

5. It is known that sewage and industrial pollution cause drastic, large-scale changes in the life near to the seabed but the detailed nature of these changes саn be revealed only microscopically. If the effects of pollution are to be counteracted, and assuming that waste continues to be discharged untreated into the sea, then the underwater microscope will undoubtedly play a large part in determining what action must be taken.
