Satellite altimetry is successfully developing during the past three decades for sea level, ocean dynamics, coastal oceanography, planetary waves, tides, wind and wave, ice cover, Earth’s gravity field, climatology research. We propose a new essential add-on of satellite related to peculiarities orbits Topex/Poseidon Jasons’ missions which were not mentioned before in scientific publications. Derived subsets “self-crossover” “inter-crossover” points sub-polar latitudes are discussed detail context water exchange, wind-wave potential challenges be solved. The relatively short time lags between measurements at these crossovers provide additional information on anomalies magnitudes directions currents, characteristics wind-driven waves. Resulting data snapshots with constant space intervals can regarded as series virtual buoys, an analog continuous buoy speed, wave height. Areas World Ocean where specific occur described studies, value special studies monitoring seas illustrated by case study.
