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.
Asked in Math and Arithmetic, Oceanography
What is mathematics in oceanography?
In oceanography, you would use mathematics in determining depth of ocean, position on the ocean, salinity and temperature of the water, speed of ocean currents, and so on. Yes, & it can be extremely complex maths too. "And so on" would include for example wave behaviour, sediment transport & deposition, current vectors not just just speeds, tidal calculations... There are virtually no areas of the natural sciences that do not use mathematics, often to very advanced levels. Even botany & zoology would use areas...

A wetland that contains a mixture of fresh water and salt water is called?
A mixture of fresh water and salt water is called brackish water. A wetland containing brackish water is called a brackish marsh. ...
Asked in Oceanography, Pangaea Supercontinent
What is the Pangaea puzzle?
The Pangea puzzle is the theory of the beginning of the continents. It's how the Earth started out. Well it is the theory of how the continents came to be. The legend has it that way back in time, there weren't any continents. There was just one large landmass. Until it started to spread apart. That is when it was no longer just one piece. But there were 7 different landmasses. Over hundreds of thousands of years, those landmasses spread apart...
What does insular mean?
n·su·lar [in-suh-ler, ins-yuh-]-adjective 1.of or pertaining to an island or islands: insular possessions. 2.dwelling or situated on an island. 3.forming an island: insular rocks. 4.detached; standing alone; isolated. 5.of, pertaining to, or characteristic of islanders. 6.narrow-minded or illiberal; provincial: insular attitudes towardforeigners. 7.Pathology . occurring in or characterized by one or moreisolated spots, patches, or the like. 8.Anatomy . pertaining to an island of cells or tissue, as theislets of Langerhans. -noun9.an inhabitant of an island; islander. ...
Asked in Earth Sciences, Oceanography, Ocean Tides
How does low tide occur?
The gravitational pull between the Moon and the Earth stretches the oceans slightly in an oblong shape, like a pulled water balloon. High tide is under (or directly opposite) the moon, while low tide is when the moon is half an orbit away. ...
Asked in Volume, Weight and Mass, Oceanography
How much does sea water weigh per cubic foot?
The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot. ----------- The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to...

Is Gigantism a trait often seen among many animals in the deep ocean waters?
Gigantism (and it's opposite, dwarfism) can occur in any isolated environment. We call it insular gigantism or insular dwarfism (although it doesn't always happen on an island, just in an area that is island like, such as deep underwater and in the middle of the jungle). This is how we think the Pygmies evolved in the middle of the jungle. There is an island called Flores in Indonesia. Here we can find giant rats and other things that are way bigger than...
Asked in Oceanography
What happens when freshwater and salt water collide?
It becomes what is know as brackish. An example of brackish water is the Chesapeake Bay, fresh water enters at the top of the bay from the Susquehanna as well as about 100 other streams and rivers. The bay then opens into the Atlantic Ocean. The Chesapeake is tidal, but is also constantly being fed with fresh water. ...
Asked in Seasons, Oceanography, Ocean Tides
How is neap tide and spring tide alike?
spring tide is when the moon and the sun are aligned and the force of gravity pulls the tides outward on the sides and thinner on top which makes high tides higher and low tides higher while neap tides are when the moon is at a 90 degree angle with the earth and sun and pull more to were low tides are lower and high tides are lower. ...
Asked in Oceanography
What is a pycnoline?
The boundry between the surface water and deep water. *boundary We know that warm water stays atop cold water. In fact, the change in temperature is abrupt, not gradual. The warm water layer is almost uniform in temperature. So is the cold water layer below. The dividing interface---pycnoline---is where the temperature changes from warm to cold. ...
How much salt is in the earth's oceans?
We have three ways to say this answer. A link is provided below. The salt content of the earth's oceans is on the order of about 3.5%, or 35 parts per thousand (35 ppt). The volume of salt is something approaching 14,000,000 cubic kilometers. The number is so large, it is hard to comprehend. Is 1.4 x 1010 kilograms any more comprehensible? Again, those last two numbers are just a ball park upper limit. But gosh, they're big. There are 11,000,000 cubic miles...
How do oceans affect climate?
The sun is what drives all weather on Earth but the ocean directs the sun's energy to different parts of the world. Oceans have the ability to absorb, store, and deliver the sun's energy. Ocean currents carry warmer water from the tropics into colder regions. The heat from that warmer water escapes into the atmosphere as it travels, creating warmer, rainier weather than might otherwise be expected. Upwellings along the California coast bring cold water up from the bottom of the ocean. This is...
