Scientists have used detailed high-band satellite imagery, envisaged by the Maxwell Technologies Digital Globe to detect and describe the four different types of species. This week's magazine was published Marine mammal scienceThis research is a big step to study the whale in remote and inaccessible places to enable scientists to monitor and change the population changes.
Each species is found in one of the well-known aggregate areas where they are interconnected: the southern right of California, the whale from Hawaii, the fillet whale, which consists of the Plymouth Coast and gray whales in the Mediterranean. It has already helped whale conservation authorities to define 10 key unwanted whales that have been used by satellite imagery.
Hannah Cubains, a veteran ecologist at the British Antarctic Research (BAS) and Cambridge University, notes:
"This is the most detailed image from satellites, which is much more interesting to see that the improved resolution (now in the 30 cm) is characterized by characteristic features such as flippers and flicks that are primarily depicted in the image.
"Whales live in all oceans, many of the territories are hard to be accessed with boats or aircraft, with the traditional fishermen of surveillance. The ability to track the ability to travel in remote and inaccessible areas is worth the conservation effort whales."
The survey also shows that some species are easier to identify by satellite. Finish and gray whales are easier to identify because of their body color contrary to the surrounding waters. Humpback whales and southern right whales are more difficult to detect because they are similar to color in their environment. In particular, the humpback whales of acrobatic behavior makes it harder to see because they are amazed about so much and so forth. Their body shape is often obscured.
The group has studied seven huge images of the digital Global World-3 satellite open ocean, covering more than 5,000 km2 area in the county of Norfolk, or Delaware.
Jennifer Jackson, a vehement ecologist, wrote in the newspaper "BAS" to launch an expedition to South Africa's Sub-Antarctic Island in Georgia. He says:
"This new technology can be a game-changer that helps to find whales, cracked whales like Chile-Peru's right whale (winter in winter).
"My project, which is a southern whale in the south-south, can be studied if this species has recovered after the whaling, many deaths have been found on the foundation of the Valdez in recent years, to prove the most useful measures in the whale populations such as the southern right whales in the future."
