Episode 06 - "Dead In the Water"

While the ocean may seem impossibly vast, human caused climate change may have begun to kick off a mass extinction on a scale never seen before on Earth. The combined effects of warming, deoxygenation, and acidification are wreaking havoc on these vast sections of earth - and the animals that live in it (maybe dooming us in the process). Join us this week as we explore how carbon dioxide (and our role in releasing it) is destroying the world's oceans and may ultimately leave us all dead in the water.

Ocean models predict declines of 1 to 7\% in the global ocean O2 inventory over the next century, with declines continuing for a thousand years or more into the future. An important consequence may be an expansion in the area and volume of so-called oxygen minimum zones, where O2 levels are too low to support many macrofauna and profound changes in biogeochemical cycling occur. Significant deoxygenation has occurred over the past 50 years in the North Pacific and tropical oceans, suggesting larger changes are looming. The potential for larger O2 declines in the future suggests the need for an improved observing system for tracking ocean O2 changes. }, doi = {10.1146/annurev.marine.010908.163855}, eprint = {https://doi.org/10.1146/annurev.marine.010908.163855}, url = { https://doi.org/10.1146/annurev.marine.010908.163855
