Jasmin Graham teams up with Weathered host, Maiya May, to search for sharks in the Gulf Stream off the coast of Jupiter, Florida. With shark researchers, Deborah Azevedo and Hannah Medd, as their guides, Jasmin and Maiya discuss the impacts of the July 2023 ocean heatwave on sharks and what future events like this one might mean for these cold-blooded creatures.
On Sharks Unknown, host Jasmin Graham joins her peers in shark science to investigate mysteries including shark migration, the effects of climate change. Jasmin and her guests connect on how their lives inform and impact their research.

There was a doc about the red sea and this exact thing too. It was a year of unprecedent attacks in the area as well. There were various reason around the attacks but the major factor considering the conditions of the sharks caught was the heat wave. The animals were in horrible condition and borderline starving since there metabolism was pushed into high gear by the heat.

Wow, this video highlights the critical importance of understanding the far-reaching consequences of ocean heat waves on marine ecosystems, especially the incredible role sharks play. It's crucial that we continue to raise awareness about these issues and support conservation efforts. Let's protect our oceans and the magnificent creatures within them for future generations. Kudos to the host for presenting such a informative and engaging video on this important topic. Keep up the great work in spreading awareness and advocating for our precious marine life! 🦈💙

Shark attacks are really rare. Most species target fishes and would rather avoid humans. Regarding your question, according to forbes, shark attacks seem to be declining in occurence, though we can't know for sure what is the primary cause.

@PBSTerra This "possible" 101 degree F. temperature recorded off the coast of Florida. Is this a single data point? Are there any other temp readings at that time in the region to corroborate the finding? How long did this condition last before returning to average temps? Can you tell us when the reading was taken? Neat episode with great information, but I would like to see a little more detail on what was the principle argument for the video other than a "possible" 101 degree temperature reading. Thank you for your time.

Sharks will nibble on the people that are cooler than the water eventually .. Like meat sack ice cubes for sharks .. Oceans are bad n'kay .. Stay in the mountains where there aren't any sharks, or Box jellyfish, or blue ringed octopus, or lionfish, or big steel submarines with silly navy guys singing sea shanty songs and drinking rum. (Just kidding, we (living creatures) need healthy oceans. Regardless of what happens to the oceans, the Earth will be fine until the sun goes shark on the planet, and eats it all up).

@@justinofearth One of the reasons you sound like a crazy person is because you believe that the fact: "Earth's temperature has dramatically fluctuated above and below the temperatures we see today" is some obscure knowledge that only a handful of conspiracy theory people know.
