Scientists have started using satellites, which are able to produce high-resolution imagery in an attempt to monitor the whale strandings are from the area, according to a study by the British Antarctic Survey, and four of the Chilean research institute.

They believe that it is a new technique for the analysis of satellite imagery, the manner in which the stranded whales were discovered at a secluded place.

By 2015, more than 340 million whales have been involved in a mass stranding in a remote area in the south of France. The evidence of the shipwreck had not been discovered for a number of weeks, due to the inaccessible nature of the area, on the Chilean coast, — from the air and boat surveys in the assessment of the extent of the damage, just a few months after it was discovered, according to the study, which was published in the Plos One magazine.

“The acquisition was done on a massive scale, and it was very impressive, but it is also possible that some of the carcass was washed back into the sea in a storm, and they were simply not counted. The 343 number was only a “best estimate” BASS’s whale expert, Dr. Jennifer Jackson, told the BBC.

Because of the delay, a lot of the whales are still missing and their mutilated bodies all over the floor, it was very difficult for scientists to determine how they died. A satellite image shows the counted number is less and less whales than that of the original aerial photograph and, more significantly, in the second photo, you may be referring to the fact that a lot of it had washed away, by the time that the non-satellite, aerial photos were taken.

They say that the use of satellites it is possible to make the discovery, of difficulty in finding the whale strandings, more efficient, and less expensive than the others. It is believed that it will inform researchers of the information that they are not able to see it with planes, and boats, according to the study.


“This is an exciting development in the monitoring whales from space,” Dr Peter Fretwell, the lead author of the British Antarctic Survey, told the BBC. “We have a high-resolution “window” on the planet earth, satellite imagery can be a quick and cost-effective alternative to aerial surveys, which we estimate to be the size of a mass whale stranding events, especially in remote and inaccessible areas.”

The researchers discovered that the whales using Very High Resolution (VHR) satellite images of Maxar Technologies, it has been found able to identify the shape, size, and color of the whales and can even be the cause of the city’s beaches.

The researchers say that the photo of the Worldview-2 satellite to show the features of greater than 50 cm (19.7 inches) from an altitude of about 700 km (435 miles). They are said to be due to a whale shape, then to 10m (33.8 ft) in length, that is, it can provide a good overview of the animal in its generic form. Improved satellite imagery technology, with a 30 cm (11.8 inches), the resolution should be to make the job even easier for you, according to the study.

In the analysis of images taken by WorldView-2, the researchers will check whether there is a white form, and sort them by how confident they are convinced that the particular image was of a whale, the study added.

“It’s important for us to harness the human and technological progress, in order to do a better job of understanding and protecting the natural world,” Jennifer Jackson, a molecular phylogeneticist at the British Antarctic Survey, told the Earther.


Let’s hope this new technology allows for a faster and more efficient way to understand how the stranded whale may have been dead — and before the weather and the natural forces of impact on the environment, and the distortion of their findings.
