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.

How many spring and neap tides will a tide-recording station experience in a given month?
A tide-recording station will experience two spring tides and two neap tides in a given month. Spring tides occur during the full moon and new moon phases when the Sun, Moon, and Earth are aligned, creating higher high tides and lower low tides. Neap tides occur during the first and last quarter moon phases when the Sun and Moon are at right angles to each other, resulting in lower high tides and higher low tides.
Is a maritime polar air mass likely to be dry and cold?
Yes, maritime polar air masses are typically cold but moist, as they form over cold ocean waters. The moisture content can lead to cloudy and damp conditions, especially when the air mass interacts with warmer land areas.
What can be either a precursor to a star or the remains of a star?
A nebula can be a precursor to a star, where gas and dust are slowly collapsing to form a new star. Stellar remnants, like white dwarfs, neutron stars, and black holes, are what remains after a star has gone through its life cycle and exhausted its nuclear fuel.
Does the Mediterranean Sea have warm water?
Along the coasts in summer, the water in the Mediterraneanis warm, as indicated by the many beaches in France, Spain, Italy, and Greece, and in northeastern Africa. While the eastern Mediterranean (near Turkey) is not as far north as the western part, the warmest temperatures are off Libya and can reach 88 degrees F (31 degrees C). The coldest temperatures are in the winter in the Adriatic Sea, as cold as 40 degrees F (5 degrees C). The water can be 3000 feet deep in the central Mediterranean, where the deep layers have an average temperature of about 55 degrees F.
What part of the earth is covered with water one-fourth one-half or three-fourths?
Three-fourths of the earth's surface is covered with water. This water is mainly found in the oceans and seas.
What effect does waves and currents have on shorelines?
wave direction at sea is determined by the wind,waves usually roll toward shore at an angle.But as thhey touch bottom,the shallower water slows the shoreward side of the wave first.The rows of waves gradually turn and become more nearly parallel to the shore.
Why is iodine considered a trace element in seawater?
A trace element is considered is a specific element that contains less than 100 parts per million in a sample. In this case, the sample is seawater.
According to my understanding, the presence of iodine is very limited in seawater. There is only 0.05 parts per million of iodine in seawater.
As such, iodine is considered a trace element in seawater.
Have oceans risen or fallen during the past 100 years?
Oceans have risen during the past 100 years. Sea levels have been rising due to factors such as thermal expansion of seawater and melting glaciers and ice sheets caused by global warming. The rate of sea level rise has been increasing in recent decades.
Which ocean is known for having rich levels of krill?
The Southern Ocean is known for having rich levels of krill. Krill are a keystone species in this region and play a crucial role in the ecosystem as a primary food source for many marine animals, including whales, seals, and penguins.
What made accurate navigation possible?
Accurate navigation became possible through advancements in technology, such as the development of GPS (Global Positioning System) satellites. GPS allows users to determine their exact location utilizing signals from these satellites, leading to precise navigation worldwide.
What is the cause of the level of earths oceans dropped?
Changes in global sea levels can be caused by a variety of factors. These include thermal expansion of the ocean due to increased temperatures, melting of ice caps and glaciers, changes in ocean currents, and tectonic movements. Each of these contributes to the complex dynamics influencing sea level change.
What are three examples of geosphere?
- Mountains - large landforms that are a part of the Earth's geosphere.
- Rocks - solid mineral material that makes up a significant portion of the geosphere.
- Soil - the outermost layer of the Earth's geosphere that supports plant life and provides nutrients for ecosystems.
What is chert chemically primarily composed of?
Chert is a sedimentary rock composed of pure silica, occurring either in interlayered beds with other sedimentary rocks or as odd-shaped or rounded lumps called nodules found in other sedimentary rocks. The bedded form is often composed of the skeletal remains of tiny marine organisms, and these skeletons can be seen with the aid of a microscope. The nodular chert is formed from the precipitation of quartz from silica-rich ground water, and appears with frequency in limestone.
For starters, Ice Scientists have taken Ice Samples from literally thousands of locations all over Earth's surface.
Surprise! They each and all 'go back' not hundreds but many hundreds of thousands of Years. Yes, we possess a complete Record of Our Earth's Past [eventual] History!
Many other Means-of-Analysis derive from these Ice Core Samples - most notably Gas Chromatography.
Are earthquakes cause more damage near the epicenter?
Yes, earthquakes typically cause more severe damage near the epicenter because the energy released decreases as you move away from the epicenter. The intensity of shaking and resulting damage decreases with distance from the source.
Are there two Pacific Oceans Why?
No, there is only one Pacific Ocean. It may be a misconception based on different regions or times being referred to, leading to confusion.
What ocean is the largest on Earth?
The Pacific Ocean is the largest ocean. It covers 69,375,000 square miles (155,557,000 km2), or 35% of the earth. The Pacific Ocean makes up almost half of all the oceans; it is almost as big as the other four oceans combined. Its deepest point is the Mariana Trench (Challenger Deep) at 11,033 metres. As the earth spins around, there is a viewpoint from outer space where all you can see is the Pacific Ocean.
The Pacific Ocean is between Asia on the west and north and South America on the east. It connects to the Indian Ocean to the west, to the Southern Ocean to the south, and to the Arctic Ocean to the north.
The Atlantic Ocean is the second largest ocean. The Atlantic Ocean covers 41,105,000 square miles, or 21% of the earth.
The Indian Ocean is the third largest ocean. The Indian Ocean covers 28,900,000 square miles, or 15% of the earth. The Indian Ocean is between Africa on the west and Asia on the north.
The Southern Ocean is the fourth largest ocean covering 7, 848, 000 square miles.
The Arctic Ocean is the smallest of all the oceans covering 5, 427, 000 square miles.
The Pacific Ocean is the biggest ocean in the world. The Artic is the smallest.
What kinds of Squids do Tiger Sharks eat?
A giant squid will eat up to 500 lbs. of fish, crab, shark or any other ocean animal per day.
Depends on what kind of squid you are talking about. If you are talking about giant squid, then they eat large fish, some crustaceans, and even young whales and sharks. Other squid of a smaller size will eat small fish, small crustaceans (including shrimp), and other squid. The shells of the crustaceans do not present a problem for the squid due to the squid's hard beak which is hard enough to break the shells of said crustaceans. Hope this helps! Have a great day! : )
Why does new crust form but the earth doesn't get larger?
New crust is constantly being formed at mid-ocean ridges through volcanic activity. However, the Earth does not get larger because as new crust is formed, older crust is subducted back into the mantle at subduction zones, maintaining a relatively constant amount of crust on the Earth's surface.
Why does the sea appear blue even though water is colorless?
The ocean appears blue because water molecules absorb light from the red part of the spectrum and scatter light in the blue part of the spectrum more efficiently. This scattering causes more blue light to reach our eyes, making the ocean appear blue.
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.
How does the empting of a large lake fit into the concept of the water cycle?
The emptying of a large lake would be part of the water cycle through the process of evaporation and precipitation. When the water from the lake evaporates, it becomes water vapor in the atmosphere, eventually leading to condensation and precipitation, which can fall back into the lake or elsewhere as rain or snow. This completes the water cycle for that specific body of water.
