How deep can photosynthesis occur in the ocean?

How deep can photosynthesis occur in the ocean?

Sunlight can penetrate 100 meters to 200 meters (about 330 feet to 660 feet) into the ocean, slowly dimming as the depth increases.

How does ocean depth affect photosynthesis?

The plants decrease with depth. Sunlight decreases with depth. Photosynthesis decreases also. Deep ocean water contains more Oxygen (gas) than middle ocean water, because water is cooler and under pressure.

How much photosynthesis occurs in the open ocean?

Approximately half of the photosynthesis on Earth occurs in the oceans, and the remainder on land. Ocean and land plants share the same basic requirements for photosynthesis and growth. These requirements include water, light and nutrients.

What is the maximum depth that photosynthesis occurs in water?

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level.

What are the 3 zones of the ocean?

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

What is the crush depth for a human?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

Can a human Go to the bottom of the ocean?

(CNN) — What lies in the chasmic depths at the bottom of the world’s seas? American undersea explorer Victor Vescovo has become the first person to dive to the deepest points of the earth’s five oceans, and he’s now back on dry land to reveal his discoveries.

How cold is bottom of ocean?

Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

Can oceans freeze?

Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. At least 15 percent of the ocean is covered by sea ice some part of the year.

Why is Hawaii water so warm?

Because the current is warmer than the surrounding atmosphere, the air above the water convects and forms clouds. (It is the Trade Winds themselves that cause this by pushing Sun-warmed surface waters toward Asia.) The counter current (however it got started) carries some of that warm water back to Hawaii.

Where is the warmest water in Hawaii?

According to data from the National Oceanic Atmospheric Association (NOAA), the warmest water off Honolulu can be found from July to September—averaging 80 to 81 degrees Fahrenheit.

The rare phenomenon gained public attention after the 2013 documentary Sharknado.

Can a hurricane pick up a whale?

When a storm churns across the ocean, the warm surface waters provide additional moisture and can fuel the storm into a hurricane. Sharks, whales, and other large animals swiftly move to calmer waters, however, and, generally speaking, are not overly affected by hurricanes.
