The thick, brown, nutrient-rich sea vegetable called sugar kelp is believed to be the next superfood, and it's being grown right off the coast of Long Island.

Stony Brook University scientists have partnered with three local oyster farmers, setting up kelp farms in the Great South Bay, the Long Island Sound and Moriches Bay. The experiment is to see if growing and harvesting kelp will work in Long Island waters, and it does.

Marine scientist Michael Doall says kelp is not only a superfood, it also helps the marine environment by removing nitrogen and carbon dioxide.

Paul McCormick started his oyster farm called Great Gun Shell Fish in Moriches Bay in 2013. He says adding kelp as a crop adds biodiversity and another stream of income.
