Now, scientists can monitor whale strandings via satellites from space
Analysing satellite images using a new technique may help scientists detect and count stranded whales from space, a new research has found.

A new technique for analysing satellite ims may help scientists detect and count stranded whales from . Researchers have reportedly tested a new detection method using Very High Resolution (VHR) satellite ims from tech company Maxar Techlogies to come to conclusion. y hope that technique will le to real-time information as stranding events happen in future. This could revolutionize how stranded whales, that are de in water or beach, are detected in remote places.
study has been published in journal PLoS ONE by British Antarctic Survey and four Chilean research institutes.

At British Antarctic Survey, le author Peter Fretwell told media that it is an exciting development in monitoring whales from as re is w a higher resolution 'window' on our planet. He ded that satellite imry may be a fast and cost-effective alternative to aerial surveys allowing researchers to assess extent of mass whale stranding events, especially in remote and inaccessible areas.
Earlier incidents of stranding
As per records of earlier incidents of stranded whales, over 340 whales — mostly from sea — were stranded in a remote region of Chilean Patagonia in 2015. As per reports, whales could t be discovered for several weeks owing to remoteness of region. Aerial and boat surveys assessed extent of mortality several months after discovery. Soon after stranding events, more ims were captured.

recent development is expected to reduce such events. Researchers from British Antarctic Survey and four Chilean research institutes studied satellite ims covering thousands of kilometers of coastline, which provided an early insight into extent of mortality. As quoted by m, y could identify shape, size, and color of whales, especially after several weeks when animals turned pink and orange as y decomposed. Jennifer Jackson from British Antarctic Survey said that causes of marine mammal strandings are poorly understood and refore, information gared helps understand how se events may be influenced by overall health, diet, environmental pollution, regional oceagraphy, social structures, and climate change. Jackson hoped that new technique will become a useful tool in obtaining real-time information which will allow local authorities to intervene earlier and possibly help with conservation efforts.
