Abstract
In thisfind decade and towards theendof 20th century, a number of satellite sensors capable of providing
data on radiance from the sea surface are destined to be launched, enhancing opportunities of synoptic
observation in the coastal zone. Japan is now at a stage of launching a sensor as well as planning of data
reception from relevant sensors. This paper discusses some of the key factors in view of full utilization of
coastal zonecolorremotesensing in Japan. Firstly, a peculiarity of the regional atmosphere which may lead
erroneous satellite estimate is indicated. Secondly the paper introduces the concept of dominant spatial
scales in the marginal seas of Japan which will help interpreting satellite-derived information field. The
paper also attempts to provide the technical concepts which may underline the efforts in bridging the gap
between the informationsource and targets.
