A scientist, Chris Reddy from Woods Hole Oceanographic Institution, collects oil-laden "sand patties" on a Louisiana beach two years after the oil spill. Watch a video of Chris Reddy talking about...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
Sandy beaches are home to a Diversity of Life In the Shores and Shallows Gallery of the Smithsonian's Sant Ocean Hall , a beach display features magnified grains of sand and the tiny beach critters...
Salmon are one of the most widely loved varieties of seafood in the world. A ubiquitous alternative to meat and poultry, salmon wear a halo of healthfulness, as they are rich in protein and omega-3...
