Upwelling

 

 

 

 

 

 

 

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

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

AUSTIN, TexasNov. 23, 2020 /PRNewswire/  

Ocean Infinity is excited to announce plans for the next phase of its Armada fleet of robotic vessels with a signed contract for eight 78-metre, optionally crewed robotic vessels.

Designed for today's tasks but with tomorrow's in mind, these exceptionally fuel-efficient, onshore-controlled vessels will initially only utilise a skeleton crew onboard.  In due course they will be capable of working with no personnel offshore whilst also consuming solely renewable fuel such as ammonia.

"The impact and the scale of this robotic fleet will spark the biggest transformation the maritime industry has seen since sail gave way to
