Ocean information is collected using different types of remote sensing techniques such as optical, thermal, microwave and so on. This paper gives a review of various remote sensors used for the estimation of coastal hazards, Sea Surface Temperature (SST), bathymetry, coastal vulnerability, Suspended Sediment Concentration (SSC), ship routing, chlorophyll etc. Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 are the widely used satellite data products for the bathymetry. Ocean color and hence the derived parameters like chlorophyll, suspended particulates and bathymetry are determined by visible wave band sensors. The same sensors are also used for determining the surface roughness, surface winds, wave height, wave spectra, internal waves and surface slicks. Active radar instruments are also used for this. Microwave sensors are useful for observing sea surface temperature, salinity and surface roughness. Infrared sensors are used for determining sea surface temperature. Surface slopes can be determined using active radar instruments.
