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.
What happens when the winds in the tropics blow warm surface water out to sea?
When winds in the tropics blow warm surface water out to sea, it can disrupt the natural ocean currents and circulation patterns, which can impact the distribution of nutrients and affect marine life in the region. This phenomena is known as upwelling, where colder, nutrient-rich waters from deeper in the ocean rise to the surface, potentially leading to changes in 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 does upwelling bring to the surface of the ocean?
Upwelling involves a wind-driven motion of nutrient-rich water towards the ocean surface. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers. This produces more fish for humans.
The lack of upwelling during an El Niño period results in which of the following?
The lack of upwelling during an El Niño period results in a decrease in nutrient-rich cold, deep ocean water reaching the surface. This leads to reduced primary productivity and affects marine ecosystems that depend on these nutrients.
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.
An upwelling brings nutrients from the floor of the ocean to the surface?
TRUE
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.
What is the process that brings nutrients to the surface of the ocean?
Upwelling
What brings greater concentration of dissolved nutrients to the ocean surface?
Upwelling
What action of bringing great concentrations of dissolved nutrients to the ocean surface?
Upwelling
Describe coastal upwelling and the effect it has on fish populations?
Cooler deep ocean water contains many nutrients. When this water rises, due to upwelling, these nutrients rise to the ocean's surface. These nutrients can then feed fish, providing large regions of successful coastal fisheries.
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.
Which ocean process brings vital nutrients from the bottom to the surface waters?
Upwelling is the ocean process that brings vital nutrients from the bottom to the surface waters. It occurs when cold, nutrient-rich waters from the deep ocean rise to the surface, fueling the growth of phytoplankton and supporting a vibrant marine ecosystem.
What upwelling tell their advantage or good effect?
Large amounts of dissolved nutrients are brought to the ocean's surface.
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.
What types of ocean water movement give scientists the strongest proof that the ocean is a vast reservoir of nutrients?
