Why is NASA Spying on Plankton from Space?
2014-07-19 01:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: NASA is bringing together marine and atmospheric scientists for a very unusual purpose. The space agency says that it wants to spy on phytoplankton from space. Starting July 20, NASA's Ship-Aircraft Bio-Optical Research (SABOR) team will make coordinated flights over the Earth's oceans in the UC-12 airborne laboratory, testing new tools that can collect in-depth data on phytoplankton even from remarkable heights. So why spy on the microscopic plants that cover the Earth's oceans? According...

A Fresh Look at Iron, Plankton, Carbon, Salmon and Ocean Engineering
2014-07-18 18:09:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Two years ago this month, an edge-pushing environmental entrepreneur and a company formed by a Native Canadian village set off a wave of international protest by dispersing a pink slurry of 100 tons of iron-rich dust over one of the 60-mile-wide ocean eddies that routinely drift across the salmon feeding grounds of the Gulf of Alaska. Their goal, in the face of steep declines in Pacific salmon catches, was to trigger a plankton population explosion with the infusion of iron, a vital nutrient thats...

Arctic climate researchers zoom in on plankton
2014-07-17 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Alaska Public Media: Theyre not recognizable like polar bears or whales. But phytoplankton are a key part of life in the Arctic and now, theyre at the center of a new research effort to predict how the region will respond to climate change. Almost every animal in the Arctic eats - or eats something that consumes - phytoplankton. Theyre tiny specks of algae that usually blossom into big clouds out in the ocean in the springtime. But thats not what Kevin Arrigo saw a few years back. He was in the Chukchi Sea...

North Sea Plankton Bloom Seen from Space
2014-05-31 15:37:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Ghostly and blue-green, a phytoplankton bloom meanders across the North Sea in new satellite imagery. The satellite image was taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Terra is part of a team; along with another NASA satellite, Aqua, it images the entire surface of the Earth every day or two. The picture of the phytoplankton bloom was taken on May 30. Phytoplankton are microscopic plantlike organisms that drift in the oceans. Blooms occur when...
Oxygen Analysis in Ancient Plankton Fossils Offers New Clues about Ice Ages
2014-04-17 22:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: A new method of establishing deep-sea and surface temperatures across the last 5 million years provides "crucial" information about how the ice ages came about, according to scientists. The study, published in the journal Nature, offers the first evidence that long-term trends in cooling and continental ice-volume cycles were not the same, while also providing new information on climate relationships that led to the development of ice ages over the last 2 million years. "In fact, for temperature...
