Many marine organisms depend on upwelling to bring nutrients to the surface How might El Nino affect a fisherman's way of life?
Upwelling is a process in which cold, nutrient-rich water from the deep ocean rises to the surface and replaces warm surface water. The warm water is blown out to sea by prevailing winds But every 2 to 12 years, the south Pacific trade winds move less warm water to the western Pacific. As a result, surface water temperatures along the coast of South America rise. Gradually, this warming spreads westward. This periodic change in the location of warm and cool surface waters in the Pacific Ocean is called El Nino. El Nino not only affects surface waters but also changes the interaction between the ocean and the atmosphere, resulting in changes in global weather patterns.

How does upwelling affect the distribution of nutrients of the ocean?
Upwelling brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water. Without this motion, the surface waters of the open ocean would be very scarce in nutrients.
Why are upwelling areas usually very productive fishing areas?
Since upwelling displaces the warmer water with less or no nutrients (located on the ocean surface) with the colder water with more nutrients (located near ocean floor), upwelling water contains more nutrients. These nutrients come from dead or decaying organic matter on the ocean floor, which release nutrients like phosphate and nitrate. When these nutrients are brought up to the surface water, phytoplankton use these nutrients, along with energy from the sun, to perform photosynthesis and produce organic compounds.
How does upwelling affect biological activity?
Upwelling is a process where deep, nutrient-rich waters rise to the surface, bringing essential nutrients that stimulate phytoplankton growth. This increase in primary production supports higher trophic levels, enhancing the abundance and diversity of marine life, including fish and other aquatic organisms. As a result, upwelling zones are often characterized by high biological productivity and are crucial for fisheries. Overall, upwelling significantly boosts the overall health of marine ecosystems.
Describe the two steps of upwelling?
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
What is the rising of cold water from deeper layers to replace warmer surface water called?
This process is called upwelling. Upwelling occurs when winds push surface water away, allowing cold, nutrient-rich water from deeper levels to rise up to the surface. This phenomenon is important for supporting marine ecosystems by bringing nutrients to the surface and supporting the growth of phytoplankton.
How does upwelling bring fish or nutrients to the surface?
Upwelling occurs when deep, nutrient-rich waters rise to the surface, providing an influx of nutrients that support the growth of phytoplankton. Phytoplankton are the base of the marine food chain, attracting fish and other marine organisms to the area in search of food. This process makes upwelling regions some of the most productive marine ecosystems in the world.
An upwelling brings nutrients from the floor of the ocean to the surface?
TRUE
What carries nutrients to the oceans surface?
Upwelling
What is the process that brings nutrients to the surface of the ocean?
Upwelling
What best describes the importance of upwelling to humans?
An upwelling is when a deep ocean current rises to the surface, bringing nutrients to the surface.
The abundance of nutrients at the ocean's surface is a result of?
The abundance of nutrients at the ocean's surface is a result of mixing from ocean currents and upwelling, which bring nutrients from deeper layers to the surface where they can fuel the growth of phytoplankton and other primary producers. Sunlight also plays a crucial role in promoting photosynthesis in these organisms, leading to the production of organic matter that sustains the marine food web.
What brings greater concentration of dissolved nutrients to the ocean surface?
Upwelling
How does upwelling affect the distribution of nutrients of the ocean?
Upwelling brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water. Without this motion, the surface waters of the open ocean would be very scarce in nutrients.
What does upwelling carry with it when it happens?
Upwelling in the oceans usually bring nutrients from the depths to the surface. So heralding the start of the food chain.
What action of bringing great concentrations of dissolved nutrients to the ocean surface?
Upwelling
How does the process of upwelling affect the distribution of life in the ocean?
The water brought to the surface by upwelling tends to be richer in nutrients than the water it replaces--more nutrients, more life.
How does upwelling affect the productivity of many regions of the ocean including waters off the coasts of California and Peru?
Upwelling increases productivity by lifting nutrients to the surface.
