Dear Deeply Readers,
Welcome to the archives of Oceans Deeply. While we paused regular publication of the site on September 1, 2018, we are happy to serve as an ongoing public resource on ocean health and economy. We hope you’ll enjoy the reporting and analysis that was produced by our dedicated community of editors and contributors.
We continue to produce events and special projects while we explore where the on-site journalism goes next. If you’d like to reach us with feedback or ideas for collaboration you can do so at [email protected].
As temperatures rise, oxygen levels in the ocean are falling, threatening marine life and coastal economies. But the only solution to deoxygenation is to dramatically reduce greenhouse gas emissions – and it may already be too late.
The ocean has lost 2 percent of its oxygen in just 50 years. Now scientists have for the first time measured a devastating loss of oxygen in ancient oceans, which could help them quantify future losses.
Researchers are trying to figure out what the appearance of millions of bioluminescent pyrosomes off the United States’ northwest coast means for the food chain, fisheries and ocean health.

Too many nutrients washing into our waters create oxygen-deprived “dead zones.” But voluntary steps to reduce nutrient runoff and shrink dead zones just aren’t working, says environmental researcher Don Scavia.
As waters warm, ocean oxygen levels are falling. Scientists say marine “dead zones” are already expanding, putting fisheries and the ecosystems they depend on in peril.
