Seagrasses growing on the seafloor of the Chesapeake Bay rely on light to grow—but, thanks to pollution, that sunlight has become more scarce. Nutrient runoff from fertilizers causes microscopic algae (phytoplankton) to grow rapidly...
Algae, like all organisms, normally grow in balance with their ecosystems,...

Many species of pink coralline algae cover a reef surface in the Southern Line Islands. Often unnoticed, these pink algae crusts help to cement coral reefs together, providing extra support and habitat for animals that live on...
Sargassum fluitans , a.k.a. “Gulfweed,” forms dense clumps up to the size of...

DIVE DEEPER

Seagrasses are found in shallow salty and brackish waters in many parts of the world, from the tropics to the Arctic Circle...
A strain of this green seaweed, native to the Indian and Pacific Oceans, escaped public and private aquariums in California, Japan, Australia, and Monaco. It has spread widely in the Mediterranean,...
Most people try to avoid rotting kelp at the beach. The feeling of a floating piece of seaweed wrapping around an ankle is enough to shake even the most steeled swimmer, and then there's the strong...
Squids, octopuses and cuttlefish, such as this Australian Giant Cuttlefish ( Sepia apama ), compose just one group of animals that call seagrass beds home. Clams and worms bury themselves in the mud...

The open ocean is surprisingly barren to the naked eye. Every now and again you will encounter a school of fish and their attendant predators, but most of the life that you find is gathered around...
Both humans and sea lions get sick from eating fish and shellfish that have been feeding on harmful toxic algae. Studying the sick sea lions brings scientists closer to understanding and preventing...
How do plants respond to rising CO2 levels? To find out, plant physiologist Bert Drake at SERC exposed marsh plants near the Chesapeake Bay to CO2 levels expected in 50 and 100 years. Different...
When snorkeling in the Kahekili Herbivore Fisheries Management Area (KHFMA) in West Maui, I keep an eye out for certain kinds of fish. Not the brightest or the biggest, but those herbivores such as...
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...
Bacteria are everywhere in the ocean. They live in the water, on virtually every living and non-living surface, and even inside other organisms . There are 1 million bacterial cells in every...
Over the past several decades, Florida’s coastal wetlands have been changing. Along the eastern shore, researchers have seen small mangrove trees appearing in areas further north than they usually...
Macroscopic Algae ( Acetabularia crenulata ). More about mangrove ecosystems can be found in the Mangroves section .
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
It is a well-known fact that for animals living in the deep sea, food can be scarce. The food that is around usually rains down from above as dead animals and organic particles from plankton living...
Nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that could provide the key to our understanding of one of the biggest threats to coral reef survival: Ocean Acidification...
Johnson's seagrass ( Halophila johnsonii ) is the lone ocean plant species listed under the Endangered Species Act. Its flowing green stalks play an important role in coastal ecosystems, where they...
An invasive strain of the plant Phragmites australis dominates this Chesapeake Bay wetland. The plant can easily grow up to 3 meters (9.8 feet) tall and alter coastal ecosystems. Scientists at the...
Deep-sea corals miles away from the source of the Deepwater Horizon oil spill in 2010 were impacted by the plumes. One affected site was 13.7 miles (22 km) away from the Macondo wellhead—the farthest...
