Description
Summary:Characteristics of the diurnal rhythm of the bioluminescence field are analyzed on the basis of experimental data obtained in the region around Kamchatka peninsula (50°31[variant prime]N; 163°50[variant prime]E). The feasibility of reconstructing the nocturnal structure of the bioluminescence field by measurements made at other times of the day has been demonstrated. Diurnal rhythm parameters for the bioluminescent field of several other studied areas of the ocean have been defined. The temporal parameters feature linear latitudinal dependence. At the equator the boundaries of morning and evening transition periods are 05:06 to 07:30 and 17:48 to 19:54 hrs, respectively. In the Barents Sea in spring these boundaries are 02:42 to 04:06 and 19:48 to 21:12 hrs. Boundary times of diurnal rhythm do not deviate from the linear regression by more than 10%.
