Latest Plankton Stories
U.S. government oceanographers say they've determined plankton carbon particles in the Southern Ocean never reached the deep ocean. Jim Bishop and Todd Wood of the U.S.
Researchers have discovered where basking sharks â€“ the world's second largest fish â€“ hide out for half of every year.
Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year.
Scientists in Germany and India said an experiment to determine whether depositing hundreds of tons of dissolved iron in the Southern Ocean can diminish global warming has produced disappointing results.
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.
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.
A new study found that ocean acidification caused by climate change is stripping away the protective shell of tiny yet vital organisms that absorb huge amounts of carbon pollution from the atmosphere.
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.
An international team of scientists has solved a mystery that has puzzled marine chemists for decades. They have discovered that fish contribute a significant fraction of the oceans' calcium carbonate production, which affects the delicate pH balance of seawater.
The Mediterranean feather star is a filter feeder that obtains food by straining suspended matter and food particles from water. The star has a stalk that has up to forty tendrils, (threadlike organs) which help the star cling to hard surfaces. The “body” of the star is called a calyx and is shaped like a small cup. This calyx is surrounded by feathery pinnules bearing arms. These arms are quite unique in the fact that they can regenerate if one should get broken off; these arms extend to...
Image Caption: Chilean Sea Urchin, Loxechinus albus. Credit: Dentren/Wikipedia (CC BY-SA 3.0) The Chilean sea urchin (Loxechinus albus) is a species that can be found along the coastlines of Chile and Peru. It is typically found in shallow waters at or below the tide level, buried in sand or lying just on top of it. This species is often associated with Macrocystis pyrifera, a type of kelp. It is most often found in more open spaces. The Chilean sea urchin can reach an average width of...
The White-spotted jellyfish is also known as the Australian spotted jellyfish (Phyllorhiza punctata). The jellyfish feeds primarily on assorted snail species and thrives in the southwestern Pacific. The bell of the White-spotted jellyfish averages 17-19 inches in diameter but there had been a maximum reported size of 24 inches. However, on Sunset Beach in North Carolina in October, 2007, a White-spotted jellyfish was found on the shore measuring in at 28 inches, perhaps the largest to...
The Tarakihi or Jackass morwong, Nemadactylus macropterus, is a morwong of the genus Nemadactylus found off the coast of southern Australia, the Atlantic coast of South America, and all around New Zealand to depths of about 1312.34 ft (400 m). Its length is between 11.81 and 23.62 in (30 and 60 cm). The Tarakihi is similar to the Porae but with a silver body color and a distinctive black saddle immediately behind the head. Their diet is similar to that of the Porae but also with a wide...
- One who brings meat to the table; hence, in some countries, the official title of the grand master or steward of the king's or a nobleman's household.
