Phytoplankton Bloom and Ash from Puyehue-Cordón Caulle Volcano Off Argentine Coast

Argentina - November 24th, 2011

More than five months after its initial explosive eruption, Chile’s Puyehue-Cordón Caulle volcano continues to produce impressive plumes of ash.  Here, one such plume can be seen blowing eastward off the coast of Argentina and over the Atlantic Ocean.

Visible beneath the veil of ash is a green phytoplankton bloom, most evident near the bottom edge of the image. Although individual phytoplankton are microscopic and rarely live more than a few days, when conditions are right, phytoplankton populations can grow explosively, a phenomenon known as a bloom. Blooms in the ocean may cover hundreds of square kilometers and are easily visible in satellite images, as can be observed here.

Ash Cloud from Puyehue-Cordón Caulle Extending Out Over Atlantic

Chile and Argentina - October 17th, 2011

Chile’s Puyehue-Cordón Caulle volcano is creating ash clouds again that have led to the cancellation of at least 100 flights in Argentina and, to a lesser extent, cancellations in Chile, Paraguay and Uruguay.

The volcano first erupted on June 4 and has been periodically letting off ash clouds ever since. The latest ash cloud emerged from the volcano on Saturday, October 15th (click here for an image from that date). Here, the ash can be seen extending eastward over the Atlantic Ocean.

Aftershocks from the volcanic event were felt strongly in Buenos Aires causing the city to go dark in the afternoon of Oct. 15 and cause travel advisories to be released by the highway patrol on routes 2, 8, 12 and 33.

Flights are being cancelled due to the fact that the volcanic ashes could cause airplane malfunctioning if the ashes were to clog the jet engines. Buenos Aires’ Aeroparque wasn’t operational after midday Oct. 16 and delays occurred at Ezeiza leaving thousands stranded. The re-appearance of ash closed the route to the international airport of San Carlos de Bariloche.

Chile and Argentina - October 15th, 2011

Chile’s Puyehue-Cordón Caulle volcano acted up again this week releasing a cloud of ash that spread across Chile and over Argentina. In the lower half of this image, a whitish ash cloud can be seen fanning out from the volcano.

In the upper half of the image, some tan-colored ash can be seen hangin over the province of Buenos Aires, between Bahía Blanca and the city of Buenos Aires (upper right corner, appearing as a greyish-tan area on the shores of the brown, sediment-laden Rio de la Plata Estuary).

Ash From Puyehue Volcano Still in Air Off Argentine Coast – August 26th, 2011

Argentina - August 22nd, 2011

Volcanic ash from the Puyehue-Cordón Caulle volcanic eruption in Chile can still be seen hovering in the air off the coast of Argentina, south of Bahía Blanca and Peninsula Valdes, across the San Jorge Gulf, and past Punto Deseado.

Puyehue and Cordón Caulle are two coalesced volcanic vents that form a major mountain massif in Puyehue National Park in the Andes of Ranco Province, Chile. In volcanology this group is known as the Puyehue-Cordón Caulle Volcanic Complex (PCCVC). Four different volcanoes constitute the volcanic group or complex, the Cordillera Nevada caldera, the Pliocene Mencheca volcano, Cordón Caulle fissure vents and the Puyehue stratovolcano.

Chile and Argentina - August 15th, 2011

Volcanic ash from the Puyehue Volcano in Chile can be seen spreading over the Andes Mountains and across Argentine Patagonia. The ash partially obscures the Piedra del Águila Reservoir, although the El Chocón Reservoir can be observed at the upper right.

The Puyehue-Cordón Caulle volcanic eruption has be going on since June 4, 2011. Scientists have determined that the eruption is actually from the Cordón Caulle fissure of the volcanic complex, although most media continue to refer to the event as the Puyehue eruption.
