How can upwelling affect the nutrient and oxygen content of ocean water around coastlines?

How can upwelling affect the nutrient and oxygen content of ocean water around coastlines?

Effects of Upwelling Because the deep water brought to the surface is often rich in nutrients, coastal upwelling supports the growth of seaweed and plankton. These, in turn, provide food for fish, marine mammals, and birds. Upwelling generates some of the world’s most fertile ecosystems.

What skill would most likely benefit any scientist who is designing a scientific experiment to test a question 3 points?

Explanation: Creativity is the soul of the experimental procedure. The researcher or experimenter should be creative enough to design a experiment based on the knowledge and skill he or she posses.

How do upwelling currents near the shore affect the abundance of aquatic organisms along the shoreline?

How do upwelling currents near the shore affect the abundance of aquatic organisms along the shoreline? They bring nutrients towards the shore, increasing the abundance of organisms. A marine scientist measures the energy found in a system consisting of a shark and fish.

What is a pseudoscience marine science?

The study of the ocean, including its ecosystems and inhabitants, and the physical and chemical processes that take place there, also known as oceanography. What is Pseudoscience? ( Glossary definition) A discipline or approach that pretends to be or has a close resemblance to science but has no scientific basis.

How do scientists investigate a problem?

Steps of a scientific investigation include identifying a research question or problem, forming a hypothesis, gathering evidence, analyzing evidence, deciding whether the evidence supports the hypothesis, drawing conclusions, and communicating the results.

Is it safe to swim in ocean at night?

It isn’t safe to swim in the ocean at night. Swimming in the ocean at night can pose a greater risk than swimming during daylight hours, especially for inexperienced swimmers. This is due to the loss of vision in the darkness, the lack of people nearby, and the nocturnal behavior of ocean predators.

What are the 3 temperature zones in the ocean?

There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.

What’s the difference between a sea and an ocean?

Is Red Sea the same as Dead Sea?

The Dead Sea is the lowest point on the Earth’s surface and has no outlet. Nearly 7 mn tonnes of water evaporate from it daily. The Dead Sea is the lowest point on the Earth’s surface and has no outlet. If the Dead Sea is 3 mn years old, then the Red Sea dates back to some 25 mn years.

Are seas saltier than oceans?

The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years. A second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater.

Why is ocean water salty and freshwater not?

Rain replenishes freshwater in rivers and streams, so they don’t taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it. In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).
