Is it practically possible to estimate the world population of whales by analyzing satellite imagery obtained from space? The answer is, Yes!
And how is that possible? Considering that whales are cryptic marine animals with a diving ability of approximately 1000 ft depth, for up-to one hour. Well, the how lies in the coastal aerosol spectral band (0.43-0.45µm)-which reflects blues and violets and which penetrate clear waters to a depth of up-to 20-30 meters. The aerosol band is becoming increasingly popular for satellite sensors such as Landsat-8 and WorldView-3, and is ideal for estimating the population of large marine animals.
