摘要：

Regressional relations between sea surface temperature and NOAA satellite advanced very high resolution radiometer radiometric data, and between in situ temperature and nitrate concentrations in the surface and subsurface waters of the Ushant tidal front were significant. Nitrate images constructed from satellite-derived temperature data agreed well with sea truth data. Nitrate transport into the euphotic zone in a spring-neap tidal cycle, as deduced from satellite images, agreed with nitrate uptake rate and phytoplankton productivity. It is suggested that satellite-derived nitrate images can be useful tools for assessing nitrate-based productivity over large geographical areas in short time intervals.
