Characteristics of the summer 1987 flow field in the Ionian Sea

open access: yesJournal of Geophysical Research: Oceans, 1993
We present an extensive analysis of the first complete data set in the northern Ionian Sea collected during the Physical Oceanography of the Eastern Mediterranean (POEM) general circulation survey of September 1987. A four water mass structure of the basin is found to be represented by a first internal baroclinic Rossby radius of deformation of 11.8 km.
