 Britain’s Royal Air Force released dramatic images of what is believed to be the world’s largest iceberg as it drifts from the Antarctic shelf towards South Georgia island. Using enhanced technologies fitted aboard an RAF Airbus 400M, the crew, which is part of the British Forces South Atlantic Islands (BFSAI) force, captured detailed images of berg for scientists to study and predict the impact of this and other icebergs.

Known as A68a, the berg broke away from the Antarctica ice shelf in July 2017. At the time, scientists estimated its size at nearly 6,000 sq km (approximately 2,300 sq. miles). They said it could weigh more than

Nazaré, la ola más grande del mundo: inédito vídeo homenaje en 4K




Going Deeper - Love letter to Nazare es una pequeña pieza sobre la ola gigante que rompe en la costa de Portugal, viral con la marejada del huracán Epsilon.


"No es un film de action sports. De hecho no es ni un vídeo de surf. Es una historia humana sobre las olas más grandes que el hombre ha conocido. Un tributo a Praia do Norte.

Así se presenta el documental Going Deeper - Love letter to Nazare.

La producción de Huxham Creative Studio dirigida por el propio Luke Huxham cuenta con varios personajes

An Upwelling Crisis: Ocean Acidification


October 30, 2009

Oceanographer Richard Feely stands on the deck of the Wecoma during a 2007 research cruise off the Washington-Oregon coast. A winch is poised to lower a rosette of empty canisters and sensors into the roiling sea. The samples will be used to study how carbon dioxide is raising the acidity of sea water and jeopardizing the survival of oyster larvae.

Richard Feely walks through the Pike Place fish market admiring the bounty and diversity of marine treasures on display at the market—rows and rows of mussels, clams, scallops, tuna, and other seafood favorites are piled high on open beds of shaved ice. Shouts of “We fillet for free!” and “Best catch

Learning Goals 10e: Describe the processes that drive coastal upwelling, and explain how upwelling and sea surface temperatures create fog.

We introduced the concept of upwelling back in section ‘9c Walker Cell and ENSO’, but here, we will look at it in closer detail and explore the relationship between upwelling and sea fog.

Upwelling is the rise of cold, nutrient-rich water from the deep ocean to the ocean surface. Similar to ocean currents, it is influenced by winds, the Coriolis effect, and Ekman transport (Learning Goal 9d). In the North Pacific, winds travelling along the west coast line of North America exerts drag on the water and causes the water to move. Then, the Coriolis effect and Ekman transport act together on
