Circumventing this marginal sea imposes significant costs in terms of extra fuel, wear and tear on equipment, and crew fatigue, but such challenges are manageable compared to rounding South America or Africa.
For Spykman, dominating such marginal seas is crucial to projecting power into the Eurasian rimlands and thence into the vast interior.
Enterprise solutions for owner operators for one of the most challenging projects in the Barents Sea, a marginal sea

The opposite is also true: obtaining or losing sea control in a marginal sea or enclosed seas is considerably influenced by the course of events in the war on land.
A fleet operating in one or more enclosed or marginal seas might opt for, or be forced by circumstances to accomplish, a combination of objectives--general sea control in the enclosed sea theater, and contested control in a semi-enclosed sea or parts of the adjacent oceans.
To complete the project Thales mobilised a heave compensated SMR 200 drilling spread, together with a high-capacity derrick mounted over the vessel's moon pool, ensuring maximum stability in marginal sea
In particular marginal Seas
such as the Baltic Sea, the second largest brackish water area in the world, are affected.
During the interglacial period, the sea level rose and the land bridges disappeared, thereby interconnecting previously isolated marginal seas and facilitating dispersal over vast geographical ranges (Liu et al.
Pleistocene isolation in the northwestern Pacific marginal seas and limited dispersal in a marine fish, Chelon haematocheilus (Temminck and Schlegel, 1845).
Various dense overflows from marginal seas
such as the Mediterranean are even smaller, 1 to 3 million cubic meters per second.
Most, if not all, fossil oceanic crust on land is now believed to be atypical, formed in young rifts, around island arcs, and in marginal seas
above subduction zones.
