海洋表面温度和NOAA卫星高级甚高分辨率辐射计辐射数据之间的回归关系，以及现场温度和Ushant潮汐前沿表面和次表层沃茨硝酸盐浓度之间的回归关系都很重要。卫星温度数据构建的硝酸盐图像与海洋实况数据吻合良好。从卫星图像推断，在一个春季小潮周期的真光层的硝酸盐运输，硝酸盐吸收率和浮游植物生产力。有人建议，卫星获得的硝酸盐图像可以是有用的工具，在很短的时间间隔内评估大的地理区域的硝酸盐生产力。
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.
