- It is very clear from the CTD profiles [you can see them on the http://www.gulfhypoxia.net web site, click on balloon, click on "for further information"] that the farther west we go and the closer to shore we go, the deeper the mixed layer becomes. The lower salinity surface waters are no longer as distinct in a gradient away from the rivers and the coast, and not as low (i.e., mixed with the saltier water below). The hypoxia that remains is in deeper water. There is also a very well defined nepheloid layer in deeper water that has been developed as the swells continue to work their way across the shelf. These are in areas of extremely low oxygen, 0.1 mg/L or so.
- Fini! Almost. The western end of the hypoxic area was not closed off, but came close before we headed back this AM to finish work disrupted by Hurricane Dolly. Size of the area will be posted soon. Watch for final map and Press Release.
