Differences in Phosphorus and Nitrogen Delivery to The Gulf of Mexico from the Mississippi RiverBasin  Environ. Sci. Technol. 2008, 42, 822–830

A team of scientists from NOAA, the Louisiana Universities Marine Consortium (LUMCON), and Louisiana State University is forecasting that the size of the “Dead Zone” off the coast of Louisiana and Texas this summer should be between 4,770 and 6,900 square miles, an area approximately the size of the state of Connecticut. The “Dead Zone” is the name for the seasonal change in areas of the Gulf of Mexico where algal growth, stimulated by input of nutrients such as nitrogen and phosphates from the Mississippi and Atchafalaya rivers, settles and decays in the bottom waters, leading to decreased oxygen levels.

EPA:  The Science of Ozone Depletion

Questions to consider:

What are the sinks for Cl in the stratosphere?

According to the U. of Cambridge, what is a recipe for ozone depletion?

What is the status of this years Antarctic ozone thinning, compared to last year and the overall average?
