Condition of Oceans

“Lowest numbers of cod on record”

“Across the United States, changes in our climate and our oceans are having very real and profound effects on communities, businesses, and the natural resources we depend on — including our economically valuable fisheries …” declared a NOAA Fisheries webpage updated in June. “Understanding these changes and measuring their impacts is an important part of NOAA Fisheries’ mission.”

Hippocratic Oath For Ocean Protections?

The marine environment globally is challenged by a number of factors, including environmental degradation, habitat destruction, overfishing, and climate change, so there is a real need for protection. Under the Convention on Biological Diversity, the international community has agreed that we will protect 10 percent of the oceans in marine protected areas by 2020.

Nitrite Pollution Increase in Ocean Water

Researchers have more than once warned of “dead zones” and toxic algal blooms as a consequence of changing climatic conditions. Ocean temperatures are increasing, and this in turn encourages a new set of biochemical processes.

Professor Hollibaugh and a colleague report in the journal Environmental Science and Technology that over the course of eight summers they measured peaks of nitrite, alongside massive increases in the numbers of the microorganisms that produce it, in coastal waters off Georgia.
