Oceanography

Oceanography, also called marine science, is the study of oceans. It includes the study of physical oceanography, marine chemistry, marine geology, and marine biology. Areas covered in oceanography are the shape, depth, and distribution of oceans, and also their composition, life forms, ecology, and water currents, as well as their legal status. If you would like to know more or share your knowledge about oceanography, ask and answer questions here! Includes questions related to the study of Earth's oceans and seas.

What is the main reason that the oceans are becoming more acidic?

User Avatar

Asked by Wiki User

Ocean acidification is caused from the ocean being forced to absorb vast amounts of fossil fuels and carbon. The carbon that is absorbed in turn causes the waters pH to go down, thus making it more acidic.

Dissolving CO2 in seawater increases the concentration in the ocean, and thus decreases ocean pH.

When CO2 dissolves, it reacts with water to form a balance of ihttp://wiki.answers.com/wiki/Ion and non-ionic chemical species: dissolved free carbon dioxide, carbonic acid, carbonate and bicarbonate.

What is it called when the salt water flows inland from the ocean?

User Avatar

Asked by Wiki User

This process is called "saltwater intrusion." It occurs when saltwater moves into and contaminates freshwater sources, typically in coastal areas where there is excessive water extraction from wells or a decrease in freshwater flow.

What is the difference between gulf and strait?

User Avatar

Asked by Wiki User

A gulf and a strait are both geographic features related to bodies of water, but they have distinct characteristics and functions:

Gulf:

  • Definition: A gulf is a large part of the ocean or sea that extends into the land, creating a partially enclosed body of water.

  • Features:

    • Size: Generally larger and deeper than bays.

    • Enclosure: Surrounded by land on three sides and open to the ocean or sea on one side.

    • Examples: Gulf of Mexico, Persian Gulf, Gulf of Guinea.

  • Formation: Often formed by the movement of tectonic plates, erosion, or the rising and falling of sea levels.

Strait:

  • Definition: A strait is a narrow, naturally occurring waterway that connects two larger bodies of water.

  • Features:

    • Width: Typically narrower than gulfs.

    • Length: Can vary but generally longer in proportion to their width.

    • Examples: Strait of Gibraltar, Bosphorus Strait, Strait of Hormuz.

  • Function: Important for navigation, as they often serve as crucial maritime routes for ships.

Key Differences:

  1. Enclosure vs. Connection:

    • Gulf: Partially enclosed by land, extending into the land.

    • Strait: Connects two larger bodies of water and is flanked by land on either side.

  2. Size and Shape:

    • Gulf: Larger and more expansive.

    • Strait: Narrower and more elongated.

  3. Role in Navigation:

    • Gulf: Can serve as significant economic zones for fishing, oil drilling, and tourism.

    • Strait: Often critical for international shipping and naval routes due to their connecting role.

Understanding these differences is important for geography, maritime navigation, and economic activities related to these water bodies.

Why the water of the ocean is salty?

User Avatar

Asked by DebabrataSengupta

The ocean is salty because of the minerals and salts that are carried into it by rivers and streams. As water flows over rocks and soil, it picks up minerals such as salt (sodium chloride) and carries them into the ocean. Over time, these minerals accumulate in the ocean, leading to its saltiness.

What percentage of the biosphere are the oceans?

User Avatar

Asked by Wiki User

Approximately 71% of the Earth's surface is covered by oceans, which make up about 97% of the biosphere in terms of volume. Oceans are crucial for sustaining life on our planet and support a wide variety of organisms.

Which location would the ocean ridge most likely be located?

User Avatar

Asked by Wiki User

The ocean ridge is most likely to be located along the boundary of tectonic plates, such as the Mid-Atlantic Ridge. This is where new oceanic crust is formed as plates move apart, causing magma to rise and solidify.

What Are The Rescue Operations During Tsunami?

User Avatar

Asked by Wiki User

Rescue operations during a tsunami typically involve search and rescue teams looking for survivors in affected areas using boats, helicopters, or other means of transportation. These teams may also provide first aid, food, and water to those in need, and evacuate people to safer locations. Coordination with local authorities, response agencies, and other organizations is crucial to effectively carry out these operations.

First Nations people traditionally ate a variety of seafood from the ocean, including fish such as salmon, halibut, and cod, as well as shellfish like clams, mussels, and crabs. They also consumed seaweed and sea vegetables as part of their diet.

What do you call a mix of fresh and salt water?

User Avatar

Asked by Wiki User

A mix of fresh and salt water is called brackish water. This type of water is found in estuaries, where rivers meet the sea, creating a unique ecosystem that supports diverse wildlife.

Do estuaries contain both salt water and freshwater?

User Avatar

Asked by Wiki User

Yes, estuaries are coastal areas where seawater from the ocean mixes with freshwater from rivers and streams. This combination of salt water and freshwater creates a unique and dynamic ecosystem that supports diverse marine and plant life.

Why can't people travel to the sea floor without a vessel like Alvin?

User Avatar

Asked by Wiki User

The sea floor is extremely deep and subject to high pressure that would crush a person's body. Without a vessel like Alvin that is specifically designed to withstand these extreme conditions, it would be impossible for humans to safely reach the sea floor.

Do tidal waves cause damage?

User Avatar

Asked by Wiki User

Yes, tidal waves can cause significant damage along coastlines due to their massive size and powerful force. They can flood coastal areas, sweep away buildings and infrastructure, and result in loss of life and property damage. Preparedness and early warning systems are crucial in minimizing the impact of tidal waves.

Can you use a salt water boat in fresh water?

User Avatar

Asked by Wiki User

Yes, you can use a salt water boat in fresh water. However, it is important to rinse off the boat and its components thoroughly after each use in salt water to prevent corrosion and damage from the salt.

How does density affects fresh water VS salt water?

User Avatar

Asked by Wiki User

Density is higher in saltwater than in freshwater due to the higher concentration of dissolved salts in saltwater. This difference in density affects the way objects float in each type of water - objects float higher in saltwater because it is denser. Additionally, density influences the circulation of water in the ocean, with denser saltwater sinking and driving deep ocean currents.

Where fresh water runs into the ocean nursery for ocean babies?

User Avatar

Asked by Wiki User

Estuaries are where fresh water from rivers and streams mixes with saltwater from the ocean, creating a unique and nutrient-rich ecosystem. These areas serve as nurseries for many marine species, providing essential habitat and food sources for young ocean creatures to thrive and grow.

What did hydrothermal vents do during Earths first years?

User Avatar

Asked by Wiki User

In the earlier of Earth's years; the Hadean from memory; there was no water and hence no hydro- anything. This was the first 700 million years or so. (Between 4.5 and 3.8 billion years ago.)

But some very old banded iron deposits come from this early, indicating that these were precipitated by changing chemical conditions.

Another few hundred million years later, the blue-green algae appeared, and having invented photosynthesis with its attendant release of oxygen, created the large banded iron deposits. And some soft-bodied fossils, such as the Ediacaran.

What other options are there for transporting oil acrossed oceans?

User Avatar

Asked by Wiki User

Other options for transporting oil across oceans include pipelines, tankers, and barges. Pipelines can be used to transport oil overland to ports for shipment by tanker or barge. Tankers are large ships specifically designed to carry oil in bulk over long distances. Barges are smaller vessels that can transport oil along rivers and coastal areas.
