Fieroe-Shethnd Channel into the North Sea, is at its maximum in winter (in March in 

 1903, according to Robertson) and minimum in summer, must be sought for in 

 several different circumstances. Thus, the magnitude and the direction of the Atlantic 

 Stream play some part; secondly, the force with which the East Icelandic Polar Stream 

 opposes the Atlantic Stream; also, the amount of inflow of freshwater from the Baltic

Stream and so on. The explanation may also lie partly in the general circumstance, 

 that the coastal water, when cooled in winter, presses backward towards the land, and 

 again in summer, when warmed and thus of less density, spreads out from the land 

 over the surface, ju.st as observers have found it in the North Sea.
