Aerial photographs were taken of windrow accumulations in Monterey Bay on 1, 8, 15 and 22 October 1968. A Fairchild T-11 aerial mapping camera was used, with photographs taken approximately every two minutes over 40 to 60 minute periods. Windrows were marked with accumulations of computer cards, wind speed measured by cup anemometer, and wind direction taken with the aid of a MK.6 Smoke Float. Sea surface temperature, depth of the thermocline, and surface air temperature measurements were taken concurrently. An attempt was made to correlate window spacing and wind speed, to find mean deflection of windrows relative to the wind, to determine any relationship between row spacing and depth of the thermocline, and to find the response time of windrow orientation to a wind shift. Windrow spacing was found to depend on other factors than wind speed. Deflection angles varied between 20 degrees left and 20 degrees right, with 0 degrees being the most common angle. No correlation was found between depth of the thermocline and row spacing. Response time fell between two and four minutes. Author
