Influence of river water expansion on the spatial distribution of chlorophyll-a in the Kara Sea
Abstract In August-September 2013, the thermohaline characteristics of water masses and the concentration of chlorophyll-a were studied in the Kara Sea. Expansion of surface desalinated water to the north, according to the central type, influenced the spatial distribution of chlorophyll. Beyond the...
