More than oil gushed from a deep-sea well during the Deepwater Horizon oil spill: methane spewed alongside it, and lots of it. But where did it go? Most of it dissolved into the seawater, forming...
This beautiful marine diatom Chaetoceros debilis was caught in the North Sea. Not only are diatoms one of the most important oxygen producers on earth, they are also a vital link in the food chain...
Tiny plant-like organisms called zooxanthellae live in the tissues of many animals, including some corals , anemones, and jellyfish , sponges, flatworms, mollusks and foraminifera . These microscopic...
This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are...
Flower-like clusters of polyps make up this coral colony. Their pink color comes from the zooxanthellae living inside. More about coral reef ecosystems can be found in our Coral Reefs featured story .
Marc Frischer, a microbial ecologist at the Skidaway Institute of Oceanography , collects bacteria at the Smithsonian Institution’s field station in Belize. Smithsonian scientists and colleagues from...
When a whale dies, the story has just begun. The massive carcass sinks to the seafloor, where it provides food for a deep sea ecosystem on the otherwise mostly barren seafloor. There are several...
Two years ago last week, on April 20, 2010, an explosion on the oil-drilling rig Deepwater Horizon caused the largest marine oil spill in history , gushing nearly 5 million barrels of crude oil over...
Ari Daniel Shapiro is joined for this episode of The Podcast of Life by science contributor Josh Kurz, who tells the story of dinoflagellates through "music from the bottom of the food chain." There...
Hantkenina mexicana -- a foram with elongated shell chambers that lived between 45-49 million years ago, during the Eocene Epoch. This specimen is from marine sediments that were drilled in the...
Searching for useful chemicals, marine scientists grow bacteria associated with deep-sea coral on nutrient agar to identify the bacteria and test their metabolic and biochemical capabilities. Some...
Any floating object in the ocean tends to attract life; fishermen know this and deploy floating buoys to concentrate fish for harvesting. Plastic marine debris is no different and, at microscopic...
Microbes are some of the most important organisms in the sea. These miniscule organisms provide an important link in the food web between the dissolved nutrients in the ocean and larger organisms...
In the ocean, microscopic forms of algae, known as dinoflagellates , can "bloom" into dense patches near the surface, often referred to as "red tides." Some of these harmful algal blooms (HABs) are...
Imagine if a fish at the market could tell you where it came from; what would it say? "I came from a world of drifters," says one fish in this video. The world of drifters is the world of zooplankton...
Whales swimming in the ocean are never really alone. Even if one swims by itself with no other whales for miles around, it still has company—the tiny microbes that live on its skin. For a long time,...
Dinoflagellates are an important group of phytoplankton that produce oxygen in marine and freshwater. Some species form symbiotic relationships with larger animals, including corals (zooxanthellae),...
Brian Huber studies fossil organisms known as “ forams ” to learn about climate change in this video snippet from the Smithsonian Marine Collections video . More about world climate change can be...
