✦ Synopsis

The underwater light field has been studied in a hypertrophic, gravel-pit lake close to Madrid (Spain) during a one year cycle. Both the inherent and the apparent properties of the underwater light field have been weekly surveyed. As theoretically expected, there is a link between inherent and apparent properties in this lake. Evidence is given suggesting that a seasonal trend in the underwater light field seems to occur. The main factor attenuat.ing light in the vertical column is phytoplankton chlorophyll "a" but humic substances also appear to play an importtant role in light attenuation. Contents 1. 2. 3.
