Icebergs Suspend Production on the White Rose Platform
April 4 | Canada.com
Husky Energy Company’s White Rose platform in the North Atlantic was threated by icebergs. Most of the crew was evacuated and production was shut in as a precaution. A few crew members remain on the platform so that production can be turned on immediately when conditions improve - or the platform can be disconnected from the ocean floor if conditions get worse.

Satellite Images of Marine Phytoplankton Blooms
March 10 | NASA
Phytoplankton are microscopic plants that grow in the sunlit surface waters of the ocean. When enough phytoplankton grow in one place, the bloom can be seen from space. This collection of NASA images features worldwide phytoplankton blooms.

Lost City Hydrothermal Vent Field
February 23 | Woods Hole Oceanographic Institution
The chemistry at this Atlantic hydrothermal vent site may be an analog for origins of life. The vents pump ion-rich waters up from deep beneath the sea floor and huge mineral deposits accumulate on the sea floor around them. The vents at Lost City differ from the typical black smokers because the deposits forming are mainly carbonates.

Phytoplankton Blooms Near Falkland Islands
January 17 | Earth Observatory
Millions of tiny ocean plants are producing phytoplankton blooms near the Falkland Islands. The bloom is carried by the Malvinas (Falkland) Current, which passes near the Falkland Islands. This current is cold and loaded with nutrients which drive the bloom.

Greenland Auctions Oil and Gas Tracts
January 16 | International Herald Tribune
Greenland plans to auction oil and natural gas exploration leases in a number of areas. They recently sold at auction leases to tracts off of their west coast that are now free of ice for at least five months but were once considered close to almost unsuitable for development.

North Atlantic Warming Tied to Natural Variability
January 11 | Earth Observatory
“A Duke University-led analysis of available records shows that while the North Atlantic Ocean’s surface waters warmed in the 50 years between 1950 and 2000, the change was not uniform. In fact, the subpolar regions cooled at the same time that subtropical and tropical waters warmed.” Quoted from the NASA article.

Phytoplankton Bloom Off Eastern Argentina
December 28 | Earth Observatory
Earth Observatory has an interesting satellite image of a phytoplankton bloom off the Atlantic coast of Argentina. The blue-green plume is a result of billions of tiny plants growing in the ocean surface waters. The Malvinas Current travels north along the continental shelf. Its motion pulls deep, cold nutrient rich waters up to the surface. These waters act as a natural fertilizer for the production of the phytoplankton.

Sahara Dust Storms Lower Sea Surface Temperatures
December 21 | NASA
NASA satellites provide data suggesting that dust blown from the African Sahara could be responsible for one-third of the drop in North Atlantic Ocean sea surface temperatures between June 2005 and 2006. Satellite images clearly show that amazing amounts of dust are blown off of the African continent.

The Largest Feature on the Mid-Atlantic Shelf
December 5 | Clastic Detritus Blog
The 150-km-long Hudson Shelf Valley is the largest physiographic feature on the mid-Atlantic continental shelf. It is the submerged seaward extension of the ancestral Hudson River drainage system that, has not been filled with sediment. Brian Romans describes it with good illustrations on his blog.

UK Prepares Territorial Claims for South Atlantic
September 28 | Guardian.co.uk
The UK is submitting territorial claims for areas in the South Atlantic to the UN Commission on the Limits of the Continental Shelf. They are claiming thousands of square miles around the Faulkland Islands, Ascension Island and Rockall. Their motivation is probably drawn from the potential for oil and gas resources in that area.

NASA Watches Sea Temperatures for Hurricanes
August 28 | Terra Daily
From the article: Sea surface temperatures were warming up in the Gulf of Mexico, Caribbean and eastern Atlantic Ocean by the middle of August. As a result, they helped spawn Hurricane Dean in the central Atlantic, and Tropical Storm Erin in the Gulf of Mexico, both during the week of August 13.

Invasive Species Research On The Atlantic Coast
August 2 | Boston.com
The introduction of organisms from foreign locations can destroy native species and ecological balance. Researchers along the New England coast are finding some invasive species as part of NOAA’s national Sea Grant program. Increasing levels of shipping and commerce are making it easier for organisms to travel long distances and be planted in new environments.

Phytoplankton Bloom in the North Atlantic
July 8 | Earth Observatory
Earth Observatory has a spectacular satellite image of a phytoplankton bloom (a sudden growth of billions of microscopic plants in the ocean’s surface waters) which recently occurred off the southwest coast of Iceland. Large amounts of chlorophyll and other pigments within the plants, along with other materials in the water produce these enormous swirls of color in the ocean’s water that can only be appreciated from high altitude. The small image shown here represents about 60,000 square kilometers of ocean surface.
