Experts analyzing the cause of deaths of 75 melon-headed whales off Madagascar have found that the disastrous event have occurred due to sonar mapping.
Sonar mapping is a noisy technology that blasts high-frequency sounds below water to map the ocean for oil.
According to the experts, sonar mapping has probably caused the deaths of 75 melon-headed whales off Madagascar in 2008.
The mapping was done by Exxon-Mobile and the experts are from the International Whaling Commission. We can do better.
On a positive note, it may be that drones can bring down the coast and raise the frequency of animal surveys.
... a new study in mongabay.com's open access journal Tropical Conservation Science argues that using small drones may be more cost-effective, safer, and capable of reaching more remote areas. Researchers tested the accuracy of drone counts in Bazinga Game Ranch (NGR) in Burkina Faso.
The solution uses a different sampling technique than manned aerial surveys, but results are promising.
Bradar, a company controlled by Embraer Defense & Security, is to map areas in Brazil subject to natural disasters and monitor environmental preservation areas.
The key technology? Interferometric synthetic aperture radar.
