Short-term hydrographic variability in a stratified Arctic fjord
Journal homepage: http://sp.lyellcollection.org/ Fjords in the Arctic often have a more complex circulation pattern than the classical two dimentional estuarine circulation. This is due to the effects of the Earth’s rotation on stratified waters in wide fjords. Observations from a semi-enclosed fjor...
