Monthly changes in temperature at transect depth, King Harbor (depths, m). bottom water was sometimes quite warm. The surface water began to cool during the fall, late September through December, then gradually the whole water column began to cool. During winter, January through March, the water was uniformly quite cold without much vertical gradient, surface water temperatures usually varying between 14°C and 16°C and bottom temperatures between 12°C and 14°C. During the spring, April through June, the surface water began to warm, a thermocline began to form, and the bottom water was often at its coldest, 11 °C. The periods of heating and cooling and of maximum and minimum thermal diversity are also clear from figure 3 which presents seasonal tem- perature variations at transect depths. The tem- perature variation was lowest for the m transects, with means varying from °C to °C. Thermal stability was greatest for the m to m range, at which depth temperature variation was least in amplitude, and temperatures were stable for longer periods. The m to m range was warm (above 15°C) for only a short time during the fall. Distributional Patterns: The patterns of sea- sonal abundance, bathymetric and thermal distri- butions are presented in figures 4, 5, and 6. The data below refer to these figures. Figure 4.
