And a big thank you to the author of our second question, Aisling! We even got a nice drawing:
Encountering a shark while diving in a submersible can be quite common depending on the location where you are diving. Sharks do not pose a significant threat to submersibles. If there are any in the area usually come and check us out. Some sharks will hang about at the edge of the submersibles lighting, keeping an eye on us. Occasionally one will venture closer and give the pilot and passengers a fantastic and unforgettable view.
Earlier this year DSV Aurelia was operating near the Maldives and Chagos. During the 30 dives, sharks were observed on nearly every dive. The majority of sharks during this mission were Thresher and Tiger sharks.
While not the best video, here’s a Thresher Shark swimming above us
While the sharks don’t pose a threat to the submersible, the swimmer who enters the water to attach or remove the lifting line to the submersible on some motherships is more a concern. These guys and Gals are actually in the water! When operating in waters where sharks are known to be common or have been encountered, we usually minimize any swimmers in the water.
Here’s one of the swimmers going into the water!
Finally, respecting the ocean and its inhabitants is essential for the well-being of the planet. When we dive we are entering the shark’s home and should be mindful to minimize the impact of our visit, leaving nothing but bubbles!
