In a GMD highlight paper we report on spurious mixing retarding the representation of deep saline inflow events in a high-resolution general ocean circulation model of the Blatic Sea (pg. 1723, Figure 14). Here, we provide an additional visualization.
The problem arises wherever relatively fast bottom currents meet steep topography such as in between Sweden and Bornholm.
In late summer, massive blooms and surface scums of cyanobacteria emerge regularly in the Baltic Sea. The bacteria produce toxins and add bioavailable nitrogen fixed from atmospheric nitrogen to an already over-fertilized system. Despite their critical role the controls on cyanobacteria blooms are not comprehensively understood. Here we add to the discussion by retracing the origins of blooms observed from space.
