Envisat making first direct measurements of ocean surface velocities
For more than a decade space-based radar instruments have been routinely observing
ocean surface phenomena including wind, waves, oil slicks, even the eyes of hurricanes.
Now - employing the same principle as police speed guns - satellite radar has
also begun to enable direct measurements of the speed of the moving ocean surface

Scientists discover interplay between genes and viruses in tiny ocean plankton
New evidence from open-sea experiments shows there's a constant shuffling of
genetic material going on among the ocean's tiny plankton. It happens via ocean-dwelling
viruses, scientists report this week in the journal Science.

Grammar revealed in a whale's love song
Fresh mathematical analysis of the song shows there are complex grammatical rules.
Using syntax, the whales combine sounds into phrases, which they further weave
into hours-long melodies packed with information.

NASA study links "smog" to Arctic warming
In a global assessment of the impact of ozone on climate warming, scientists at the NASA Goddard Institute for Space Studies (GISS), New York, evaluated how ozone in the lowest part of the atmosphere changed temperatures over the past 100 years. Using the best available estimates of global emissions of gases that produce ozone, the GISS computer model study reveals how much this single air pollutant, and greenhouse gas, has contributed to warming in specific regions of the world.

Bering Sea Ecosystem responding to changes in Arctic climate
Physical changes--including rising air and seawater temperatures and decreasing seasonal ice cover--appear to be the cause of a series of biological changes in the northern Bering Sea ecosystem that could have long-range and irreversible effects on the animals that live there and on the people who depend on them for their livelihoods.

Japan grapples with invasion of giant jellyfish
Vast numbers of Echizen kurage, or Nomura's jellyfish, have appeared around Japan's coast since July, clogging and ripping fishing nets and forcing fishermen to spend hours hacking them apart before bringing home their reduced catches.

- Arctic Ocean ice surges onto Alaskan shore
Ridges of sea ice packing car-sized chunk of the cold stuff slammed onto a road
in this northern Alaskan town in quantities not seen in nearly three decades.

Tsunami warning centers in Pacific to go on 24/7 staffing
A portion of $24 million appropriated by Congress in May to the National Oceanic and Atmospheric Administration will allow 24-hour staffing, seven days a week at the nation's two tsunami warning centers.

- Beluga whale numbers remain flat in Alaska
A survey of beluga whales in Cook Inlet finds that numbers remain stagnant and
could be declining despite a lengthy effort to get the white whales to rebound.

Plows, plagues, and petroleum: how humans took control of climate
William Ruddiman's new book argues that humans have actually been changing the
climate for some 8,000 years -- as a result of the earlier discovery of agriculture.

Orca pods on the move
K and L pods, the two groups of orcas that leave Puget Sound each winter, may be timing their travels in a more traditional way this year. That is, they may have departed from inland waters in December rather than waiting for the new year, as they have for the past five years. Prior to 1999, they were almost always gone before January.

Underwater listening devices yield discoveries about endangered large whales
Why whales emit their characteristic calls remains largely a biological mystery,
but listening for the distinctive underwater sounds provides a valuable way to
track the movements of endangered large whales. Autonomous data-recording devices
equipped with hydrophones (underwater microphones), deployed in remote waters
off Alaska, have been used in recent years to track seasonal occurrences of blue,
fin, humpback, North Pacific right, bowhead, and sperm whales.
