Dead Zones in the Ocean - Science Nation

The video discusses oceanographic research led by Jack Barth, focusing on the use of underwater gliders to measure ocean health indicators like temperature, salinity, and dissolved oxygen. It highlights the issue of ocean dead zones, particularly off the Oregon coast, caused by factors such as agricultural runoff and climate change. The research aims to understand these zones' impact on marine life and the role of climate change in altering ocean conditions. Technological advancements, such as smart robots, are revolutionizing ocean monitoring and providing new insights into ocean dynamics.
