NASA Helps Melt Secrets of Great Lakes Ice

Two scientists from NASA and NOAA have developed a new space-based technique for monitoring the ice cover of the Great Lakes that is so accurate it can identify a narrow channel of open water cut through the ice by an icebreaker — even at night.

“In the dark, it’s difficult to read a map that’s right in front of you,” said Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., one of the developers of the new technique. “Yet we now have a way to use satellite radars almost 500 miles [800 kilometers] out in space to see through clouds and darkness and map ice across the Great Lakes.” (more…)

Scientists Discover Huge Phytoplankton Bloom in Ice Covered Waters

A team of researchers, including scientists from Woods Hole Oceanographic Institution (WHOI), discovered a massive bloom of phytoplankton beneath ice-covered Arctic waters. Until now, sea ice was thought to block sunlight and limit the growth of microscopic marine plants living under the ice.

The amount of phytoplankton growing in this under-ice bloom was four times greater than the amount found in neighboring ice-free waters. The bloom extended laterally more than 100 kilometers (62 miles) underneath the ice pack, where ocean and ice physics combined to create a phenomenon that scientists had never seen before. (more…)

New Study by WHOI Scientists Provides Baseline Measurements of Carbon in Arctic Ocean

Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean’s carbon cycle—the pathway through which carbon enters and is used by the marine ecosystem. It will also offer an important point of reference for determining how those levels of carbon change over time, and how the ecosystem responds to rising global temperatures.

“Carbon is the currency of life. Where carbon is coming from, which organisms are using it, how they’re giving off carbon themselves—these things say a lot about how an ocean ecosystem works,” says David Griffith, the lead author on the study. “If warming temperatures perturb the Arctic Ocean, the way that carbon cycles through that system may change.” (more…)

Study of Patagonian Glacier’s Rise and Fall Adds to Understanding of Global Climate Change

Glaciers play a vital role in Earth’s climate system, and it’s critical to understand what contributes to their fluctuation.

Increased global temperatures are frequently viewed as the cause of glacial melt, but a new study of Patagonia’s Gualas Glacier highlights the role of precipitation in the glacier’s fluctuation. The study, conducted by Sébastien Bertrand of the Woods Hole Oceanographic Institution (WHOI) and his colleagues, reconstructs a 5,400 year-record of the region’s glacial environment and climate, comparing past temperature and rainfall data with sediment records of glacier fluctuations and the historical observations of early Spanish explorers.

*BizSpark One startup Soundtrckr lets listeners discover, play and share music on their terms — alongside their friends.*

REDMOND, Wash. — April 27, 2011 — Soundtrckr, a BizSpark One startup, mashes Internet radio with social networking and location-awareness to help users create a soundtrack for their lives.

Sometimes, opportunity presents itself when least expected. That’s what Daniele Calabrese, founder and CEO of Soundtrckr, discovered as he boarded a plane bound to Philadelphia from Madrid. Calabrese was launching a new concept in radio called Soundtrckr, a geo-social Internet music service. In its infancy, Soundtrckr just needed the right connections to take it to the heights Calabrese was convinced it could reach. He sat down and met his seat mate. (more…)
