Beschreibung:
<p>Short-term variations in fluorescence and dissolved oxygen were recorded from a fixed station between 6 and 7 m over 12 m of water in upper Chesapeake Bay. The late afternoon curves showed a positive relationship and the early evening curves exhibited an inverse correspondence. The observed oscillations could result from internal waves but the variations in space and time may represent discrete patches of phytoplankton that move past the fixed sampling point.</p>
