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

- In Nicaragua, fear of a catastrophic hurricane gives way to relief.
- The storm is hitting a region still reeling from Hurricane Eta.
- Iota leaves flooding behind in Colombia.
- The storm complicates efforts to combat the coronavirus.
- As Iota moves inland, communities scramble to prepare.
- The most active hurricane season on record is not over yet.

A hotter and more humid world has made tropical cyclones like hurricanes and typhoons more extreme but not more deadly.
On Monday, a hurricane battered Nicaragua before moving across Central America, claiming at least 57 lives. The day before, on the other side of the world, one of the strongest storms to ever hit land struck the Philippines. Its house-ripping winds reached speeds of 310 km/h (195mph) — as fast as a Japanese bullet train — but only grazed the area around the capital, narrowly missing 14 million people.
The storms are yet another example of how extreme weather is becoming terrifyingly ordinary as the climate changes.
So many hurricanes formed in the Atlantic this season that the World Meteorological Organization exhausted its 21-name-strong alphabetical
