Why are deep waters nutrient-rich?
Deep waters are rich in nutrients, including nitrate, phosphate and silicic acid, themselves the result of decomposition of sinking organic matter (dead/detrital plankton) from surface waters.
Why is colder water more productive?
Why is cold water more productive? Cold water can hold more dissolved oxygen than warm water. The levels of dissolved oxygen in Antarctic waters are so high that many fish have few or no red blood cells (the blood cells other animals, including humans, use to carry oxygen).
Is warm water nutrient-rich?
Generally, the cooler temperatures bring nutrient-rich waters up from the deep, but during the warmer seasons, nutrients in the shallows and upper ocean — particularly nitrogen — become more scarce.
Is a process that causes the dense nutrient-rich cold water to rise up to the surface?
Upwelling is the natural process which brings cold, nutrient-rich water to the surface. A huge upwelling regularly occurs off the coast of Peru, which enjoys a large fishing industry as a result. Upwelling is a process in which currents bring deep, cold water to the surface of the ocean.
What is the most nutrient rich part of the ocean?
The highest nutrient concentrations are in the deeper waters.
Where are the most nutrients in the ocean?
You can see the highest abundance close to the coastlines where nutrients from the land are fed in by rivers. The other location where chlorophyll levels are high is in upwelling zones where nutrients are brought to the surface ocean from depth by the upwelling process.
Do cold showers make you more productive?
A 2016 study of workers who took cold showers, over a 30 day-period, found an almost 30 percent reduction in self-reported sick days, plus an improved sense of productivity.
Do cold showers make you more successful?
The body wants to stay warm, and the shock of the cold water puts it in hyper mode. The energy comes from an increased blood flow as well as the release of epinephrine which is your body's natural 'energy drug' it also helps you to focus more on the stuff you need to accomplish.
Does temperature affect chlorophyll concentration?
As sea surface temperatures increase, chlorophyll a concentrations decrease.
How surface currents influence nutrients?
It is also higher in nutrients because the higher oxygen levels allow bacteria to cycle important nutrients such as nitrate and phosphate from decomposing organic matter. As the surface water moves to the west it is replaced by cold, nutrient-rich waters in a process called upwelling.
Which current is produced by upwelling of cold water?

Is the ocean rich in nutrients?
But ocean properties vary greatly. Like different types of soil on land, some seawater is rich in nutrients, while others are nutrient-poor. If more nutrients are available, then more life can grow. With more life, the ocean can remove more carbon dioxide from the atmosphere and produce more fish for us to eat.
How do nutrients get into the ocean?
Nutrients come from a variety of different sources. They can occur naturally as a result of weathering of rocks and soil in the watershed and they can also come from the ocean due to mixing of water currents.
How do oceans store nitrogen and nutrients?
The ocean absorbs nitrogen gas from the atmosphere. In open-ocean areas with low concentrations of nutrients (“oligotrophic” regions), some of this nitrogen is taken up by microbes and transformed into various chemical compounds.

What is the relationship between temperature and chlorophyll content in leaves?
Heat stress has significant negative effect on the leaf chlorophyll content. Average chlorophyll content and NDVI decreases as the temperature increase.
Do phytoplankton prefer to live in hot or cold water?
Water temperatures strongly influence their growth rates. Phytoplankton in warmer equatorial waters grow much faster than their cold-water cousins. With worldwide temperatures predicted to increase over the next century, it's important to gauge the reactions of phytoplankton species, say the scientists.
How do ocean currents distribute nutrients?
Deep water currents return nutrients to the surface by a process known as upwelling. Upwelling brings nutrients back into sunlight, where plankton can use the nutrients to provide energy that drives an ocean's ecosystem.
How does the cold and denser water masses sink to the depths of ocean?
Cold, salty water sinks to the bottom of the ocean. Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
Why cold currents are good for fishing?
Cold ocean currents encourage the growth of plankton (small plants) as they are rich in nutrients. These give rise to rich fishing grounds.
Which of the following current is produced by a feeling of cold water?
Benguela current Was this answer helpful?
Which part of the ocean is the most nutrient rich?
With satellites we can see what fishermen find with their nets: Coastal waters are the most biologically productive portions of the world's oceans.
Where do most of the nutrients in the ocean come from?
Nutrients in the ocean are cycled by a process known as biological pumping, whereby plankton extract the nutrients out of the surface water and combine them in their organic matrix. Then when the plants die, sink and decay, the nutrients are returned to their dissolved state at deeper levels of the ocean.
Where are nutrients in ocean water stored?
In the ocean, as there is no shortage of water, the dominant factors impacting phytoplankton growth are sunlight and nutrients. Often in the open ocean, however, nutrients are at their highest concentrations deep below the sunlit surface layer of the ocean.
Do cold showers increase testosterone?
A cold shower might invigorate, improve blood circulation, give a glowing skin but it does not boost testosterone levels.
Why do hot showers feel so good?
“The heat warms up your muscles and makes you more pliable,” says dermatologist Anthony Rossi. “Your muscles are relaxed, and you're not as tense.” That's because hot water widens your blood vessels and increases blood flow, which helps transport soreness-inducing lactic acid away from tired muscles.
Are cold showers good for sperm?
Cold showers don't necessarily produce more sperm cells, but they do not pose a threat to sperm in the same way as increasing one's body and scrotal temperature would via a hot shower. One of the most concrete facts regarding cold showers is their environmental benefits.
How does temperature affect chlorophyll?
The results suggested that as the storage temperature increases so the chlorophyll degradation rate increases and so the colour degradation. From the two tested vegetables the lettuce was proved to be more sensitive to chlorophyll and colour degradation.
How does temperature affect photosynthesis?
The rate of photosynthesis is influenced by temperature. Higher the temperature, greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature.
