Back to 1997, for the first time ever, an experiment to assess the biological productivity of the marine environment in the area of the Norwegian Sea using various means of data gathering including spacecrafts, fishery vessels and specially equipped aircraft was carried out.
The results of the analysis presented in this article were obtained using “remote” and “close-up, contact-associated” measurements. The comparative analysis of sea surface height map anomalies, synthetic aperture radar images from ERS-2 satellite and sea surface temperature maps derived from NOAA satellites data is presented. It was shown that the major structures at the sea surface seen in synthetic aperture radar images match with those found in sea surface height anomaly maps and further corroborated by ship’s contact-associated data.
The lack of information on fishing conditions in the Norwegian economic zone prompted an experiment to integrally analyze hydro acoustic survey data, hydrological characteristics of marine environment and remote sensing information (with no use of information on type and size of fishing grounds) in the region of interest. The character of the hydrocoles` behavior concentrated at the edges of the mesoscale formations was confirmed as a result of this analysis.
Keywords: satellite altimetry, SAR, sea surface temperature, hydrology, comprehensive analysis, remote sensing, “Norwegian Sea’97” experiment results, commercial fishing oceanography
