Value Theory

Multiattribute value theory (MAVT) is a simplification of MAUT: MAVT does not seek to model the decision maker’s attitude to risk. [...]

Seagrass Ecosystems as a Globally Significant Carbon Stock

The protection of organic carbon stored in forests is considered as an important method for mitigating climate change. Like terrestrial ecosystems, coastal ecosystems store large amounts of carbon, an[...]

What are Blue Forests?

Blue forests – seagrass meadows, mangrove forests, kelp forests, rockweed, and salt marshes – are coastal and marine ecosystems that sequester carbon and provide a multitude of ecosystem services [...]

Future Carbon Emissions from Global Mangrove Forest Loss

Mangroves have among the highest carbon densities of any tropical forest. These ‘blue carbon’ ecosystems can store large amounts of carbon for long periods, and their protection reduces greenhouse[...]

A New Generation of Ocean Farmers are Reducing Pollution with Seaweed

Seaweed soaks up carbon and nitrogen, two pollutants lingering in the water. If ocean farmers devoted a little less than 5 percent of U.S. waters to growing seaweed, they could clean up an estimated 1[...]

The Ocean Carbon Cycle

The ocean holds vast quantities of carbon that it continually exchanges with the atmosphere through the air-sea interface. Because of its enormous size and relatively rapid exchange of carbon with the[...]

Why the Ocean Matters in Climate Negotiations

The ocean takes up heat and carbon, reducing the adverse effects of climate change. The ocean plays a central role in regulating our climate and weather. The ocean has taken up more than 90% of the ex[...]

The Carbon Cycle – Essential for Life on Earth

Carbon is an essential building block for life. Learning how carbon is converted through slow- and fast-moving cycles helps us understand how this life-sustaining element moves through the environment[...]
