The Future of our Oceans

Ours is a water planet. Technology is shaping our uses, both as foe and ally. It has made humans the dominant predator and provides us food, gives us half the oxygen we breathe and created many maritime jobs. But technology has also raised CO2 levels, caused acidic oceans, threatened ocean biodiversity and created grand climate challenges.

Marine biologists like Doug McCauley at UC Santa Barbara are also using technology to promote ocean health and provide a balance. In this talk, McCauley describes examples of technology used to help the oceans and marine biodiversity. He shows systems that track whale activity and communicate it to ships so they know where to slow down to avoid collisions. He describes technology to monitor marine protected areas, image recognition techniques to study the endangered giant sea bass and electronic tags to follow sharks.

McCauley began his career as a fisherman in the Port of Los Angeles. Eventually he migrated to marine science and UC Santa Barbara. McCauley has degrees in political science and biology from the UC Berkeley. His PhD research was done at Stanford University where he studied the ecology of sharks, giant parrotfish, and coral reef ecosystems. McCauley’s science is motivated by the belief that we must better understand how complex ocean ecosystems work if we want to better protect them from threats like overfishing, climate change, and pollution.

Shark Conservation: Safeguarding the Future of Our Ocean

On the surface, it might seem like an ocean without sharks would be a more enjoyable place. But, these predators play a very important role in the ocean ecosystem and they need our protection just like many other ocean dwelling creatures.

Sharks have been at the top of the food chain for hundreds of millions of years, but today their populations are in danger because of human activities, such as overfishing and finning (this is when people catch sharks, remove the fins, and dump the carcass overboard).

Andrew P. Nosal, Ph. D, Birch Aquarium’s new DeLaCour Postdoctoral Fellow for Ecology and Conservation, shares his shark expertise and explains that all sharks are not the evil villains seen in movies, but are essential in maintaining a balanced ocean.

Watch “Shark Conservation: Safeguarding the Future of Our Ocean” to hear about all of the benefits sharks provide and why they deserve our protection.
