Benthic-pelagic relations of aquatic organisms in various water masses of the Chukchi Sea by the data of δ 15 N and δ 13 С
To compare trophic characteristics for pelagic and benthic communities of zooplankton and zoobenthos in the Chukchi Sea, isotopic composition of carbon and nitrogen (δ15N and δ13С) was measured in two different water masses: i) the Bering Sea water with relatively high δ13С and low δ15N values that...
