Abstract: | Temperature data obtained from NUC Tower, San Diego, California during May–June 1968 provide input to a three-wave period version of MOVER, a computer model that simulates organism diurnal vertical migration through an internal wave field. The locally characteristic wave periods are 21.50 h, 12.50 h and 0.42 h. The phase of the modeled interval wave spectrum matches the field observations for a 10-day period preceding and including a red tide. MOVER's output shows a rapid aggregation of representative phytoplankton under all modeled conditions. The aggregation or red tide occurs at the geographic location of NUC Tower under certain organism behavioral regimes. Whether these conditions actually occurred at NUC Tower in May 1968 is not certain from the available data. |
