Dust and Phytoplankton of Argentine Coast - November 5th, 2009

Dust and Phytoplankton of Argentine Coast - November 5th, 2009

A plume of dust blows off the coast of Argentina, between Pinamar and Mar del Plata, south of Buenos Aires and the sediment-laden Rio de la Plata estuary. The plume widens as it spreads eastward, eventually forking in two off the coast. One part then curves back towards land, while the other blows southeast and then to the northwest.

Also visible is a phytoplankton bloom in the waters of the Atlantic Ocean. Part of the bloom is veiled by the dust, while more can be observed to the south. Off the coast of Argentina, 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.

Dust off Coast of Pakistan - November 5th, 2009

Dust off Coast of Pakistan - November 5th, 2009

Dust blows over the Indus River Valley, over Karachi, Pakistan’s largest city, and off the coast into the Indian Ocean. The dust blows towards, but doesn’t reach, the country of Oman on the lower left.

The mountains west of the Indus River, which still appears greenish through the veil of dust, prevent the particles from spreading westward, over the Iranian Plateau and into Iran.

Fires in Queensland, Australia - November 4th, 2009

Thick plumes of smoke from multiple wildfires on the Cape York Peninsula in Queensland, Australia, billow to the west towards the Gulf of Carpentaria in the main image, taken November 3rd.

The long trail of smoke originating near the east coast is from a wildfire in the Iron Range National Park. The other fires visible, on the other hand, appear to be outside national park areas. Also visible off the eastern shores is a section of the Great Barrier Reef.

The second image, taken the day after, focuses on fires further to the southeast in Queensland, in the Buckland Tableland area of the Great Dividing Range Mountains. This area, part of the Carnarvon National Park, consists of a complex of mountain ranges, plateaus, upland areas and escarpments with an ancient and complex geological history.

Other areas of Queensland are also at risk for fires, and the Queensland Fire and Rescue Service has thus put fire bans into affect for North Burnett, Fraser Coast, South Burnett, Gympie, Cherbourg, Bundaberg, Whitsunday, Burdekin, Townsville, Charters Towers, Richmond, Mackay, Isaac, Banana, Gladstone and Rockhampton. The bans will remain in place until midnight on Monday, November 9th, although they may be extended again if dangerous fire conditions continue.
