Sediments and Phytoplankton by Coast of Argentine Patagonia

40.1S 58.6W

June 24th, 2013 Category: Phytoplankton MODISAqua

Argentina – June 22nd, 2013

Phytoplankton and sediments float in the waters of the Atlantic, parallel to the coast of Argentina. Sediments are particularly dense along the coast by Bahía Blanca (upper right quadrant), while two other mixed plumes can be viewed trailing off the Valdes Peninsula (center) and the southern end of the San Jorge Gulf.

Sediments and Phytoplankton by Argentine Patagonia

Argentina – June 8th, 2013

Sediments and phytoplankton can be seen off the coast of Argentine Patagonia. The greenish plume of color streaming northeastward off Peninsula Valdes (center) is likely caused by sediments, while the band of green containing swirled patterns that is parallel, but not connected to, the coast of the San Jorge Gulf (below), is likely due to phytoplankton.

Climate Change in Patagonia, Argentina

Argentina – March 21st, 2013

Most focus on climate change in Argentina has been in the north, where impacts are more noticeable. However, new studies also show how changes in the south, particularly in the Patagonian province of Chubut, are also likely to be significant.

Increasing temperature and decreasing rainfall in northwest Chubut are shifting the patterns of agricultural viability. Predominant patterns of cattle and sheep farming are likely to face increasing shortages of dry season grazing. Natural forests and existing and planned plantations are also likely to face increasing aridity—exacerbating the risk of dieback, forest fires and pest and disease outbreaks.

Water shortage is likely to become an increasingly pressing concern—especially with the heavy reliance on hydropower, major development plans for irrigated agriculture and forestry, heavy technological demands from the petrochemical industry for water pressure to drive oil extraction, and the importance of aquatic environments for regional tourism (click here for more information).

Lakes in Argentine and Chilean Patagonia

Chile and Argentina – November 16th, 2012

Several lakes can be seen by the Andes Mountains and Chile-Argentina border in this image of Patagonia. The northernmost is known as Lake General Carrera (Chilean side) or Lake Buenos Aires (Argentine side). It has a surface of 1,850 km² of which 970 km² are in Chile and 880 km² in Argentina, making it the biggest lake in Chile, and the fourth largest in Argentina. The lake is of glacial origin and drains to the Pacific Ocean on the west through the Baker River.

Visible to its south, also dark blue in color, is known as Cochrane Lake in Chile and Pueyrredón Lake in Argentina. The Argentine portion of the lake has a surface of 150 km2, while the portion in Chile covers 175 km2. It is a glacier fed lake.

Continuing southward, three light blue lakes can be seen: Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino Lake. All three are glacial lakes, and their milky color is due to rock flour suspended in their waters.

Green and Blue Phytoplankton Off Coast of Argentine Patagonia – November 15th, 2012

Argentina – November 14th, 2012

Phytoplankton continues to create blue and green patterns in the waters of the Atlantic Ocean off the coast of Argentine Patagonia (click here for previous images). Some bright blue phytoplankton can also be seen in the San Matías Gulf, north of the Valdes Peninsula.
