ABSTRACT

We consider the problem of combining glider and CTD data for optimal estimating thermohaline structures. In presence of meso/submesoscale variability glider profiling yields merely a distorted true temperature (salinity) field because of mixing space and time scales (aliasing). At the same time CTD data are too sparse to retrieve time evolution of the structures in question. A theoretical approach is suggested for efficient estimating time dependent fronts, intrusions, etc via combining both sources of information. The approach is illustrated by synthetic data and an error analysis is provided.
