isopycnal
/ˌʌɪsə(ʊ)ˈpɪkn(ə)l
/adjective Oceanography
(Especially of an imaginary line or surface on a map or chart) connecting points in the ocean where the water has the same density.Redfield ratios of remineralization are calculated based on chemical data analysis on isopycnal surfaces....
- It is further shown that features of the spatial structure of isopycnal displacement and velocity scales may be inferred from a single station that measures potential energy fluctuations.
- Since the isopycnal surfaces move with the fluid, this representation is in fact quasi-Lagrangian.
Origin
Early 20th century: from iso- 'equal' + Greek puknos 'dense' + -al.
