Variations in the Barents Sea outflow to the Norwegian Sea

Skagseth, Mork, Loeng, and .. in prep

Blindheim (1989); -0.8 Sv deep outflow based on mooring data from 1979,-Traced the water into the Norw. Sea. -Source interior Barents Sea

Near-bottom (15mab) T and V (along the slope)

Bear Island Channel: T,S,

Warm/saline or cold/fresh

Additionally a jump in 1989

What determines the variations of the outflow water?the Atlantic Inflow Water or Internal processes

Conclusion

• Large change in the outflow properties after about 1990, and also signature in Norw. Sea dissapear in -S space.

• Variations of the deep outflow follows the characteristics of the AW inflow, and rappid effect , T< 1 year
