Research shows oceans are becoming more acidic

...ce waters of high-latitude regions would be lower, subsurface waters would be less oxygenated, and phytoplankton would experience increased exposure to sunlight. These changes would affect many species and change the composition of biological communities in ways that are not yet understood or predictable. many...

TOPP scientists also are beginning to recognize that the data they gather, similar to those collected on Atlantic bluefin tunas, may provide useful information to resource managers working in the N...

Bacteria discoveries could resemble Mars, other planets

...e may be found on other planets. Microorganisms in subsurface environments on our own planet comprise a significant fraction of the Earth's biomass, with estimates ranging from 5 percent to 50 percent, the researchers point out. Bacteria also grow in some rather inhospitable places. Five years ago, in a stud...

Exxon Valdez oil spill impacts lasting far longer than expected, scientists say

...antities for years after the Exxon Valdez spill in subsurface reservoirs under course intertidal sediments," Peterson said. "This oil was sequestered in conditions where weathering by wave action, light and bacteria was inhibited, and toxicity remained for a decade or more." As a result, many species suffered l...

The genome analysis, he says, "revealed previously unsuspected physiological properties" of the bacterium and also gave scientists insight into the metabolic mechanisms that the organism uses to harvest electricity from the environment...

Scientists surprised at persistence of nitrate from dated experiment

...ying the nitrate takes decades to flow through the subsurface of the watershed to the stream. "We wanted to show the recommended cropping-system treatments begun in 1996 could improve water quality, but we won't be able to do that by monitoring this stream, because the newer experiment is confounded by a persi...
