Collisions have become a fatal problem for whales over the last several years. An estimated 20,000 whales are killed by shipping, cruise, and fishing vessels annually … and those are just the ones reported, with the vast majority left undocumented.
Despite the speed zoning and specific shipping lanes created to protect these gentle giants, scientists have concluded that rising ocean temps are changing the migration patterns and habits of whales … and the results are catastrophic.
With the average global sea surface temperatures on the rise, whales are having to navigate unprotected waters for food, and that unpredictability has been making it exponentially more difficult to ensure their safety from vessels in the water.
“There’s a mismatch between where the right whales are distributed and where the policies are distributed,” said Erin Meyer-Gutbrod, an assistant professor studying whales at the University of South Carolina, via Inside Climate News. “If you’re protecting the Gulf of Maine, but the right whales are, in fact, in the Gulf of St. Lawrence, you’re going to have a big problem.”
Why is whale mortality concerning?
When an endangered species is being killed at such an alarming rate, it’s a giant red flag indicating a decline in our ecosystem. It’s a forewarning that can’t be ignored, as this directly affects the circle of life — which, in this case, is not so hakuna matata.
Whales are at the top of the food chain and not only vital to marine life, but the entire planet. Playing a significant role in capturing carbon from the atmosphere, whale food cycles with phytoplankton help sequester carbon and produce the oxygen we breathe. Some scientists refer to whales as “ecosystem engineers.”
What’s being done to protect the whales?
Migratory routes are being investigated and cross-referenced with shipping routes in order to determine where changes need to be made.
Speed zones where whale activity is thought to be more active have been expanded, specifically on the west coast as of March 2023. This initiative is a win-win situation all around. It not only decreases the possibility of vessel strikes, but it also helps ships reduce their climate warming emissions.
The Blue Boat Initiative is a project that implements the use of smart buoys that can listen to the ocean and monitor climate change. With the ability to relay messages to nearby vessels in real time, smart buoys could be the key to success in avoiding future collisions. The data these hi-tech devices are able to gather is extraordinary for whale protection and the overall health of the marine ecosystem.
