Downwelling is a crucial process in ocean circulation where surface waters sink, facilitating the transport of oxygen and nutrients to deeper layers. This process supports marine life by distributing essential nutrients, promoting biological productivity in the ocean. Additionally, downwelling helps regulate global climate by influencing heat distribution and carbon sequestration in the deep ocean. Overall, it plays a vital role in maintaining healthy marine ecosystems and stabilizing climate patterns.
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material. A common example is convection currents in fluids.

Downwelling is not associated with upwelling. Downwelling refers to the sinking of surface water in the ocean, whereas upwelling is the process where deep, nutrient-rich waters rise to the surface.
Downwelling currents in the oceans typically do not directly "gain" or "lose" energy. These currents are driven by processes such as density differences and wind patterns, rather than changing energy levels. However, factors like climate change can indirectly impact downwelling currents by altering ocean temperatures and salinity, which can influence their strength and distribution.
Downwelling in coastal areas on the eastern sides of ocean basins can lead to reduced nutrient supply from deeper waters to the surface, affecting primary production and thus the food chain for fisheries. This can result in lower fish populations and decreased productivity in those areas. Additionally, downwelling can cause changes in water temperature and oxygen levels, further impacting fish habitat and migration patterns.
Upwelling is caused by currents on the surface. When water moves from the bottom of the ocean towards the surface it is called upwelling. Downwelling is when more dense water sinks. This process moves nutrients back to the deep part of the ocean.
Downwelling is the sinking of surface ocean waters to deeper depths due to the movement of colder, denser water masses. It plays a key role in redistributing heat, nutrients, and carbon dioxide in the ocean, influencing marine ecosystems and climate patterns.
They are both wind driven, if the Ekman Transport is moving in towrds the shore then downwelling will pull water from it and move it down and out. While when the Ekman Transport is moving out away from shore up welling will pull water up and feed the Transport. Note all directions are based on 90 degrees to the left or right fo the wind direction depending on wich Hemisphere.
Solidary benefits are selective benefits that are given to members of different faction groups. These benefits include friendship, networking, and consciousness raising. Solidary benefits are benefits that are the opposite of material benefits, they are intangible. --SC

Benefits is not a food. Benefits is an advantage or profit gained from something.
