Despite the decreasing biomass of immature salmon in the upper epipelagic layer in autumns of recent years, the catches of the mature salmon consistently increased in the 1 . [...] The main changes in set-up of physical conditions of the Bering Sea are ruled by interaction of the sea with air masses of Arctic and Pacific origin, water advection from the Pacific, and redistribution of these water masses within the sea. [...] This water loses heat along the way, so the core of warm intermediate layer has a temperature of about 3.8-4.0 °C in the Near Strait, about 3.7-3.8 °C in the central part of the sea, and about 3.6-3.7 °C along the continental slope of the Kamchatka Basin. [...] This means in the beginning of the twenty-first century, the upper layer of the western Bering Sea was substantially warmer than during the second half of twentieth century. [...] Those are: the deep northern part of the Bering Sea near Cape Navarin, the western part of the sea near Kamchatka Strait, and in the oceanic domain of the sea (see Figure R16-16 for domain locations) Second, we focus on interannual variability in the three mentioned areas.
