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.

Why are sea water salty?

User Avatar

Asked by Wiki User

because the river flowing into it passes through salty rock, so it picks it up and deposits it in the dead sea

Not exactly. The Mediterranean Sea has dried out completely no less than four times. When that happens, it leaves a huge layer of evaporated salt behind. The land on the eastern side of the Mediterranean has also risen (because of geologic forces) and the result today is a lake sitting on the salt deposit. That salt deposit is in a physical depression and has no outlet. It is like a bowl made of salt holding water.

Is there a sea that is half salt and half fresh water?

User Avatar

Asked by Wiki User

No, there is no sea that is half salt and half fresh water. Saltwater and freshwater have different densities, which prevents them from mixing evenly in large bodies of water. However, there are instances where saltwater and freshwater can meet, creating brackish water with varying degrees of salinity.

Satellite-mounted sensors in oceanography?

User Avatar

Asked by Wiki User

Satellite-mounted sensors in oceanography are used to collect data on various parameters, such as sea surface temperature, ocean color, and sea level. These sensors, placed on satellites orbiting the Earth, provide a global view of the oceans and help scientists monitor changes in oceanographic conditions over time. The data collected from these sensors is valuable for understanding ocean ecosystems, climate patterns, and for forecasting weather events.

How are oyster larvae affected by ocean acidification?

User Avatar

Asked by Wiki User

Oyster larvae are highly vulnerable to ocean acidification. The increased acidity of the water makes it harder for larvae to build their shells as it reduces the availability of calcium carbonate, a key building block. This can lead to slower growth and weakened shells, making the larvae more susceptible to predation and other stresses. Overall, ocean acidification poses a significant threat to oyster populations and the ecosystems they support.

What are the components of a coastal circulation cell?

User Avatar

Asked by Wiki User

The components of a coastal circulation cell include the alongshore current, the offshore current (also known as the coastward current), and the Ekman transport. The alongshore current flows parallel to the coastline, driven by factors such as waves, tides, and wind. The offshore current flows away from the coast due to the net transport of water caused by the alongshore current. The Ekman transport, a balance between wind stress and Coriolis effect, determines the net movement of water perpendicular to the coastline.

What is a definition for excessive nutrients?

User Avatar

Asked by Wiki User

Excessive nutrients refer to an overabundance of specific substances, such as nitrogen and phosphorus, in an ecosystem, particularly in the context of water bodies like lakes and rivers. This imbalance often occurs due to human activities like agricultural run-off or improper waste disposal. Excessive nutrient levels can lead to a variety of environmental problems including algal blooms, oxygen depletion, and ecosystem disruptions.

What were the four major events in oceanography that happened rigor to 1878?

User Avatar

Asked by Wiki User

  1. In 1768, the British Royal Navy organized the first scientific oceanographic expedition, led by James Cook, aboard the HMS Endeavour. This expedition laid the foundation for systematic data collection and mapping in oceanography.
  2. In 1855, Matthew Maury, a United States Navy officer, published the first comprehensive oceanographic textbook called "The Physical Geography of the Sea." This book provided a framework for understanding the physical properties and processes of the ocean.
  3. In 1868, the first successful transatlantic telegraph cable was laid, enabling real-time communication between Europe and North America. This allowed for more efficient sharing of oceanographic data and facilitated international collaboration in the field.
  4. In 1872, the HMS Challenger embarked on a four-year global expedition, conducting the first comprehensive scientific survey of the ocean's depths. This expedition greatly expanded our knowledge of the ocean and is considered a landmark event in the field of oceanography.

Why do oceanographers?

User Avatar

Asked by Wiki User

Oceanographers study the ocean to understand its physical and chemical properties, marine life and ecosystems, and the impacts of human activities on the ocean. This knowledge is important for managing and sustaining the ocean's resources, predicting and mitigating natural hazards, and addressing climate change. Additionally, studying the ocean can provide insights into Earth's history and processes, and contribute to scientific advancements and technological innovations.

What an oceanographer do?

User Avatar

Asked by Wiki User

The job of an oceangraphist is to study the ocean and the living things that live there along with non-living things to help people understand or solve the mysteries that lie beneath the deep depths of the ocean. They also swim around in the sea looking at many different things.

hope this helped you. :)

An Statement if I can make, the proper term as Ocean scientist is "Oceanographer" not oceangraphist. If you have done spell check you would have a red scribble line under oceangraphist, plus you most add an "o" in between the n and g or the middle. oceanographer. Look it up first.

Largest volcano on earth?

User Avatar

Asked by Wiki User

Measured from its base, the tallest would be Mauna Kea in Hawaii, which like the adjacent Mauna Loa has a deep seafloor base on the Hawaiian hotspot.

But the highest above sea level is the Nevado Ojos del Salado ("snow-covered salty eyes"), a stratovolcano in the Andes mountains, about 600 km (370 miles) north of Aconcagua, the highest mountain in the Americas. Ojos de Salado is 6893 meters (22,615 ft) in height. However, it has not been active since approximately 700 AD.

Underground water is called underground water, because it is "underground" not because it is fresh or salt.

You can have underground salt water reservoirs just like you can have fresh water ones.

How do the features of the ocean floor compare with the features of continents?

Asked by Wiki User

About 71% of the surface of the earth is covered by ocean. That leaves about 29% in the continents. So there is roughly 2.5 times as much ocean as continent.
