Hi Simon, you’re right that’s a weird place of hypoxia. I’ll provide an update when the report comes out.

Thanks for posting this. There’s at least one odd spot on the new map: is there really a documented case of hypoxia driven by anthropogenic nutrient loading between Somerset Island and Cornwallis Island in Nunavut, the Canadian Arctic? The only nearby community is Resolute, with a population of at most 250 people.

USGS just released a new report documenting how nine states in the Mississippi River Basin contribute the majority of nutrients to the Northern Gulf of Mexico leading to hypoxic conditions.
See “Differences in Phosphorus and Nitrogen Delivery to the Gulf of Mexico from the Mississippi River Basin” at http://water.usgs.gov/nawqa/sparrow/gulf_findings/

Also, the Gulf of Mexico Hypoxia Task Force is reviewing public comments on the draft revised Action Plan and is expected to approve the plan at the upcoming meeting in Chicago, February 28-29, 2008. See http://www.epa.gov/msbasin/
