Flights from Uruguay’s main international airport Carrasco and from Buenos Aires busiest air terminals have been cancelled Thursday until further notice because of the volcanic ash cloud which again is hovering over the River Plate as winds have changed.

Authorities in Uruguay say they have found about 600 dead penguins washed up on the Atlantic coast since Saturday. Experts are trying to determine what has killed the sea birds.

United Nations Secretary General Ban Ki-moon today (Wednesday June 8) called on all governments and peoples to play their part to ensure that the world’s oceans are protected for future generations, warning that they face major threats in the years ahead.

Argentina’s Civil Aviation agency (ANAC) and the Secretariat of Transport announced that the Ezeiza and Aeroparque airports are “now open and operating normally” as the ash cloud spewed by Chile’s Puyehue volcano late Tuesday seemed to be moving away from the Buenos Aires City and part of the River Plate area.

Flights from Uruguay’s Carrasco international airport were suspended on Tuesday until further notice because of the proximity of Chile’s Puyehue volcano ash cloud that on Monday forced similar decisions for Buenos Aires City main international and domestic air terminals.

The Chilean volcano Puyehue ash cloud has reached the Argentine capital after moving across the Greater Buenos Aires, but the due effects of the cloud are seen to be minimal. Meanwhile local airlines confirmed cancelled all flights until further notice at the international airport of Ezeiza and at the domestic-flights metropolitan Aeroparque.

The ash cloud hovering above Argentine Northern Patagonia since Saturday after the eruption of the Puyehue volcano in the Chilean Andes may reach the city of Buenos Aires on Tuesday, experts assured.

Scientists are launching an international mission to measure salt levels at the surface of the ocean. A rocket carrying an Argentine-built spacecraft is set to lift off Thursday from the Vandenberg Air Force Base along the central California coast.

Southern Chile's Puyehue volcano was calm Sunday, one day after raining down ash and forcing thousands to flee, although the cloud of ash it had belched out still darkened skies as far away as neighbouring Argentina and was heading to the Atlantic coast.

Southern Chile's Puyehue volcano erupted on Saturday for the first time in half a century prompting evacuation orders for 3,500 people and turning into dark the Argentine Patagonian resort of San Carlos de Bariloche, 100 kilometres to the east as it was covered with ash.
