Summary
1. Measurements of the penetration of daylight of different wavelengths have been carried out in the coastal waters of Porto Novo using photoelectric cells.
2. Nearly 50 per cent. of solar radiation at near ultra-violet region is absorbed by the first one meter of sea-water.
3. Longer wavelengths, especially red light, is heavily absorbed by the surface layer.
4. Selective scattering in the wavelengths 475–590 mµ has been observed in the coastal waters at Porto Novo.
