Remote sensing acquires and interprets small or large-scale data about the Earth from a distance. Using a wide range of spatial, spectral, temporal, and radiometric scales remote sensing is a large and diverse field for which this Handbook will be the key research reference. Illustrated throughout, an essential resource for the analysis of remotely sensed data, The SAGE Handbook of Remote Sensing provides researchers with a definitive statement of the core concepts and methodologies in the discipline.

Optical Remote Sensing of the Hydrosphere: From the Open Ocean to Inland Waters
ocean colour, marine optics, phytoplankton and satellite oceanography.
This chapter will primarily deal with optical remote sensing, but also mentions the use of sensors that cover the wider breadth of the electromagnetic spectrum as there is an increasing focus on sensor synergy and what all forms of remote sensing can tell us. Optical remote sensing is the detection (primarily from airborne and satellite-mounted sensors, but can also include ship and ground-mounted sensors) of the incident sunlight, in the visible and near infra-red (NIR) parts of the electromagnetic spectrum, reflected from the surface after passive interaction with the water and its constituents. ...
