Coral reefs and coastal upwelling ecosystems are the subjects of two new Long-Term Ecological Research (LTER) sites awarded funding by the National Science Foundation (NSF). With the addition of the Moorea Coral Reef LTER Site and the California Current Ecosystem LTER Site, there are now 26 NSF-funded sites in the LTER network. The two newest sites will receive approximately $820,000 for the next six years, for a total of about $ 5 million each.

“These two new sites significantly augment th

Trees and grass are usually the only “heroes” that come to mind for consuming carbon dioxide and producing oxygen for planet Earth, but they have allies in the water: phytoplankton, or in another word, algae.

Phytoplankton are mostly single-celled photosynthetic organisms that feed fish and marine mammals. They are responsible for nearly 50 percent of the earth’s annual carbon-dioxide consumption and more than 45 percent of the oxygen production. Despite the important roles of modern p

Discovery suggests presence of diamonds in northern Saskatchewan

Researchers at the University of Alberta have found evidence that a 2,000-kilometre corridor stretching diagonally across northern Canada was under tremendous pressure to split in two about 2.7 billion years ago. It is the first evidence suggesting enormous continental landforms and plate tectonics existed that long ago. “Rifts are one hallmark of plate tectonics, and there is a huge debate in our field about wheth

Scientists investigating the possible effect of underwater seismic pulses on marine mammals have conducted a series of tests, designed to better understand the force of sound waves generated by shipboard airguns. These instruments are used by some 100 vessels worldwide to penetrate into the seabed for oil exploration and geophysical research, with an estimated 15 to 20 active on any given day.

An accidental discovery may provide insights into the creation of tubular structures such as those found in caves and at hydrothermal vents.

While doing some electroplating work for a class project, David Stone stumbled upon a way to grow tiny tubes that look like the cave formations known as soda straws. At the time, Stone, a former sculptor and foundry worker, had just returned to school.

“I botched the experiment. I can still remember being in my carport, picking up the

Although it covers more than two-thirds of Earth’s surface, much of the deep sea remains unknown and unexplored, and many questions remain about how its environment changes over time.

A new study led by scientists at Scripps Institution of Oceanography at the University of California, San Diego, has shed new light on significant changes in the deep sea over a 14-year period. Scripps Institution’s Henry Ruhl and Ken Smith show in the new issue of the journal Science that changes in climate at
