What can hydrography tell Us about the strength of the Nordic Seas MOC over the last 70 to 100 years?
The flow of warm water into the Nordic Seas plays an important role for the mild climate of central and northern Europe. Here we estimate the stability of this flow thanks to the extensive hydrographic record that dates back to the early 1900s. Using all casts in two areas with little mean flow just...
