Latest Plankton Stories
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.
The icy seas between Australia and Antarctica could become a money generator by engineering nature to soak up carbon dioxide and then selling carbon credits worth millions of dollars.
Researchers in Germany and Canada reported on Thursday that climate change could effect the global food chain by supporting animals with short life spans rather than their larger long-lived predators.
Diatoms, mighty microscopic algae, have profound influence on climate, producing 20 percent of the oxygen we breathe by capturing atmospheric carbon and in so doing, countering the greenhouse effect.
A team of scientists is studying the complex ocean upwelling process by mimicking nature â€“ pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.
By BINA VENKATARAMAN By Bina Venkataraman The New York Times Many coastal areas of the world's oceans are being starved of oxygen at an alarming rate, with vast stretches along the seafloor depleted of it to the point where they can barely sustain marine life, researchers are reporting.
By Anonymous The brilliant beamlines of the Australian Synchrotron are finding a host of environmental applications, from studying the chemistry of the upper atmosphere to developing better catalysts for hydrogen production.
A Giant sea monster was brought back to life at a nature reserve to celebrate National Marine Week. Theatre group the Desperate Men brought a life-size model of a sea sturgeon, once native to the Humber Estuary, to Far Ings Nature Reserve, in Barton-Upon-Humber.
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...
