Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphereâ€™s carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to â€œsequesterâ€ that greenhouse gas as the climate warms.
Scientists have long established that the Antarctic Peninsula is one of the most rapidly warming spots on Earth.
Phytoplankton comprise the forests of the sea, and are responsible for providing nearly half of the oxygen that sustains life on Earth including our own.
Dust blown off the continents and deposited in the open ocean is an important source of nutrients for marine phytoplankton, the tiny algae that are the foundation of the ocean food web. But new findings show that some sources of dust also carry toxic elements that can kill marine phytoplankton.
Get ready to send the biology textbooks back to the printer. In a new paper published in Nature, Benjamin Van Mooy, a geochemist with the Woods Hole Oceanographic Institution (WHOI), and his colleagues report that microscopic plants growing in the Sargasso Sea have come up with a completely unexpected way of building their cells.
An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding ironâ€™s role in locking atmospheric carbon dioxide (CO2) in the ocean.
The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.
Concern about increasing ocean acidification has often focused on its potential effects on coral reefs, but broader disruptions of biological processes in the oceans may be more significant.
MIT researchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain.
Researchers say they are now using satellite monitoring of marine environments for predicting cholera outbreaks.
A salp is a barrel-shaped, free-floating tunicate (any living organism which has a saclike body enclosed in a thick membrane or tunic with two openings or siphons for the ingress and egress of water). It moves by contracting which pumps water through its body. The salp strains the water with internal feeding filters as it goes through the body. It consumes phytoplankton that are strained from the water. Salps are common throughout equatorial, temperate, and colder seas. They are most often...
The South American pilchard, Sardinops sagax, is a sardine of the Family Clupeidae, the only member of the genus Sardinops, found in the indo-Pacific oceans. Their length is up to 15.75 in (40 cm). It has a number of other common names: Australian pilchard, Blue pilchard, Blue-bait, Californian pilchard, Chilean sardine, Japanese pilchard, Pacific sardine, and Southern African pilchard. The South American pilchard is a coastal species that forms large schools. Coloration is blue green on...
