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

From Plastic to Steel: Consciousness is a Matter of Substance






Together with our crew, we move towards reducing single-use plastic water bottles onboard.

Choosing the reduce plastics onboard

The composition of plastic makes it one of the greatest environmental and marine life threat. The International Maritime Organisation (IMO)warns that plastic litter presents a huge problem to our oceans and if left uncurbed, there will be more plastics than fish by 2050.

Our shipping industry abides to MARPOL Annex 5- Garbage from Ships that streamlines the waste and garbage management onboard marine vessels. It is safe to say that there are existing guidelines in place for proper handling of waste products for vessels to prevent marine pollution.

However, following guidelines is not enough to create sustainable

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
