Images of the 2011 tsunami did not look as I had expected, and pointed to the sublime, when experience exceeds our frameworks of understanding. My exhibit ‘Salients’ treats this theme.

Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
How much would you pay to make this disappear?

What would you pay to keep trash off your favorite beach, or pollution away from a national park? Economists can tease these values out of our travel choices and use the numbers to help make policy.
Blooms of algae, like this growth in 2015 in Lake St. Clair between Michigan and Ontario, promote the formation of dead zones.

Scientists have mapped a huge dead zone in the Gulf of Oman, without enough oxygen in the water to support life. This Speed Read explains why dead zones form in waters around the world.

Nitrogen and phosphorus are polluting US waters, creating algae blooms and dead zones. New research confirms that voluntary steps are failing in the Gulf of Mexico and unlikely to work in Lake Erie.
Algae overload: Lake Erie algal bloom 2011.
