- Scientists are predicting a slighter larger than average “dead zone” for the Chesapeake Bay this summer, meaning that nearly 2 cubic miles of the Bay will lack the needed dissolved oxygen for fish and crabs. The Gulf of Mexico, on the other hand, is predicted to have average-sized dead zone, caused by excessive nutrient pollution from wastewater and agriculture. The Baltimore Sun

We all know that climate change poses a huge threat to the oceans, including rising sea levels and coral reef bleaching, but you may be wondering how that trickles down to your dinner plate. The overarching theme of the recent 1,552-page Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) found that climate change is undeniable, mostly caused by human activities, and is occurring globally.

A new study published Sunday in Nature Climate Change finds that ocean acidification could cause the Southern Ocean Antarctic krill population to crash by 2300, meaning dire consequences for whales, seals, penguins, and the entire ecosystem it supports.  In addition to devastating ecosystem effects, a collapse in krill populations could have serious economic implications, as the species represents the region’s largest fishery resource.

What Do Historic CO2 Levels Mean for the Oceans?

For the first time in human history, atmospheric carbon dioxide levels passed 400 parts per million
(ppm) of carbon dioxide at the historic Mauna Loa Observatory in Hawaii. This is the same location where Scripps Institution of Oceanography researcher Charles David Keeling first established the “Keeling Curve,” a famous graph showing that atmospheric carbon dioxide concentrations are increasing rapidly in the atmosphere. CO2 was around 280 ppm before the Industrial Revolution, when humans first began releasing large amounts of CO2 to the atmosphere by burning fossil fuels. On May 9, the reading was a startling 400.08 ppm for a 24-hour period. But without the help of the oceans, this number would already be much higher.
