The new study, by the University of Exeter, examined phytoplankton at the ocean surface and the subsurface—a distinct layer of water beneath—to see how climate variability is affecting them.

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean ...

The 2018 eruption of the Kīlauea volcano had unexpected consequences on marine ecosystems thousands of kilometers away. A ...

Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula.

Melting polar ice narrows the light spectrum underwater, favoring blue-tuned algae and disrupting the ocean food web.

Too many nutrients can cause microscopic marine algae to grow out of control with harmful effects on animals and people ...

To do this effectively phytoplankton floats near the water’s surface. Plankton bunches together and forms a plankton bloom. These blooms provide food for a huge variety of species. Every summer ...

Their presence caused the amount of seagrass in the water to decrease by over 50% ... In essence, the presence of such large amounts of phytoplankton had reduced the amount of food available ...
