Ocean Plants - Woods Hole Oceanographic Institution
Ocean plants have adapted to living in the marine environment and can vary from single cell organisms to thick forests of kelp. These plants are an important food source for invertebrates and fish, they provide oxygen to surrounding marine life, and they support many marine creatures by providing refuge and nursery grounds.
Seagrass Meadows - Woods Hole Oceanographic Institution
2021年7月26日 · The plants’ roots help hold sediment in place and their leaves slow the flow of water, reducing its power and preventing extensive erosion. When wind and water wash sediment from shore, seagrasses trap the incoming particles, …

Growing Marine Plants Need Their Vitamins
Your mother was right: You need your vitamins. And that turns out to be true for life in the oceans, too. B 12 —an essential vitamin for land-dwelling animals, including humans—also plays a vital and previously overlooked role in determining how microscopic plants will bloom in the sea, according to a new study led by biogeochemists at Woods Hole Oceanographic Institution.
Does the ocean produce oxygen? - Woods Hole Oceanographic …
Until 600 million years ago, Earth’s atmosphere had less than five percent oxygen. It was mainly a mix of nitrogen and carbon dioxide. Land plants didn’t exist until 470 million years ago. Trees weren’t responsible for the increase in oxygen. So where did it come from? The ocean. Plants, algae, and cyanobacteria all create oxygen.
Deep-sea Corals - Woods Hole Oceanographic Institution
Just like plants on land, the algae use photosynthesis to make food, which is also used by the corals. In return for food, the algae get a house—a hard coral skeleton to settle in. Deep-sea corals live beyond the zone where sunlight penetrates, which is …
Carbon Cycle - Woods Hole Oceanographic Institution
2024年9月13日 · Individual atoms move from one reservoir to another: between the atmosphere and the oceans, from plants to animals to decomposers, to sediments and rock, and eventually back to the atmosphere. This movement of carbon from one place to another, which is caused by natural and human processes, is known as the carbon cycle.
How Is Fukushima’s Fallout Affecting Marine Life?
2013年5月2日 · » 日本語版 The Fukushima nuclear disaster delivered an unprecedented amount of radioactivity into the sea over a relatively brief time. How did that pulse of cesium and other radioisotopes make its way through the marine food chain? Scott Fowler, who helped pioneer marine radioecology for more than 30 years at…
