Population Fluctuations of Jellyfish in the Bering Sea and Their Ecological Role in This Productive , medusa biomass declined to lower levels after 2000, but then increased once again in 2009. Similar population fluctuations are revealed in other monitoring efforts that extend to the northeast Bering Sea and to the west in Russian waters. Decadal oscillations in climate, rather than overfishing or
