Water exchange and mixing in a semi-enclosed coastal basin (Pohja Bay)
The processes contributing to the deep water renewal and oxygen balance of Pohja Bay are reviewed here, with reference to the extensive experimental material from the years 1990–1993. The observations reveal previously unreported frequent minor inflows of sea water into the bay. A one-dimensional di...
