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 is the ocean horizon wavy wobbly?

No clue... noticed it today for the first time.... Never seen it before and I live right on the beach in Miami.

Usually the horizon is a nice and even line, and now it is choppy. Easiest explanation would be the waves far out in the ocean, but they are way too big, and stay the same even when I use my binoculars.


It has to be some visual illusion.

A wave that moves back down the beach under the next wave?

This phenomenon is known as "backwash." Backwash occurs when the water from a previous wave recedes back toward the ocean, usually after breaking on the shore, while the next wave approaches. It plays a key role in the continual exchange of water between the ocean and the coast.

Is rain water drinkable?

You can drink it, it's sterile, and as long as it's fresh, and you don't have any UTIs bacteria free. It is, for the most part completely safe. That said, it is all the stuff your body didn't want first time through, and probably won't taste very pleasant. I imagine it would be warm, salty and acidic tasting.

"Clear" pee is mostly water, and yes, it's true the more you drink, the more diluted the stuff your body is looking to get rid of will be, but my understanding of the body is that it will never be pure water.

The human body is not very efficient, and some people even claim drinking urine is of some medical benefit, in that it gives your body a second chance to get some of the "good bits" which were unnecessarily filtered first time, though this is at best speculative.

You would mostly be very safe to do so, if you want, though it is a hard one to recommend to anyone. If you were stranded, without water, and on the verge of dehydration, then yes, go right ahead (though if you were on the verge of dehydration, you wouldn't be peeing anyway, so you would have to start storing it early on in this situation). But in the civilized world, with water on tap and better drinks readily available, it's hard to know why you would want to.

If you're gonna do it though, my suggestions would be...

1. Don't drink your first pee of the day, or the one you've been waiting for hours to "relieve yourself" of. It'll be more concentrated, stronger tasting and harder to stomach, and has more chance of containing "nasties".

2. Don't do it if you have any reason at all to believe you may be suffering any infection "down there". Don't run the risk of spreading bacteria around your body. If the smell or colour are particularly strong, or different from normal, you may have an infection, see a doctor. If there is any pain peeing or blood in the urine, you have bigger problems than drinking your pee, SEE A DOCTOR.

3. If you have drunk alcohol, or taken drugs recently, don't drink your pee. Unprocessed alcohol and drugs could, in theory, be present in the urine, and could cause you problems. Also, don't think drinking pee is a "free high" it's not, the compounds in the alcohol or drugs could be significantly changed while in your body and could do you serious damage. Your body is flushing them out for a reason.

4. Don't be tempted to refrigerate it to make it easier to go down. While fresh pee is sterile, it can grow bacteria quickly. If you must drink it, do it while it's fresh. It'll be warm, and probably not pleasant, but that's the price you pay.

5. Drink lots of water before trying it. As you said, the more water you drink the more diluted it'll be, and therefor the easier to drink it'll be. Just because it's clear though, don't expect it to taste just like water, though have no frame of reference for it, i imagine it probably won't. Don't set your sights too high. I repeat, it probably won't be pleasant.

6. Under no circumstances be tempted to drink someone else's pee. It should go without saying, yet i feel i should say it (you're considering drinking pee for a friend, so who knows where it could lead) it has all the above problems (infection, as well as added STI issues, alcohol, drugs, no way of knowing how diluted it will be) with the added problem of not knowing whether they are telling you the truth about these things.

7. Ask yourself... is this really something i want to do. Why are you even considering this? although some people enjoy it, or have particular sexual enjoyment out of this sort of thing if you're doing it just because your friend told you to, is it really worth doing? What really do you stand to gain from it? If you don't have a good answer to that, then don't do it.

In fact, my recommendation to most people is DON'T DO IT. Really, there isn't any good reason to.

What are the differences between east coast and west coast tides?

Well I would assume it's just where they are located. Most tropical cyclones are still called Hurricanes unless they are further in the pacific ocean closer to countries like Japan and the Philippines then they are called Typhoons but generally speaking Tropical Cyclones that can endanger the Americas are Hurricanes regardless of which coast they are on.

What discoveries organisms sea floor features were found with aqualung?

With the invention of the aqualung, scientists were able to discover diverse ecosystems thriving on the seafloor, such as hydrothermal vent communities and coral reefs. They also found unique species adapted to extreme conditions in deep-sea trenches and undersea caves. The aqualung enabled researchers to study these environments up close and uncover important insights into marine biodiversity and ecology.

How can you get salt from the sea?

There are more than one way to make a sea salt or table salt. But if you do not have any machine to make it, you can make it manually by having a Salt pans. Or you can make a container looks like a bath tub outside and pour it with sea water and let the sun dries up the water. After that you will see the residue and you can use it as your seasoning for cooking. Salt ponds are for the seawater storage and then let seawater evaporates and produce a salt once the sunlight eats the seawater on those ponds.

Which South pacific republic consists of 844 islands?

The Solomon Islands is the South Pacific republic that consists of 844 islands. These islands are located east of Papua New Guinea and are known for their beautiful coral reefs and diverse marine life.

What is the deepest man has gone underwater without breathing apparatus?

Nuno Gomes, a Portugese Man who's also a Portugese Footballer made it to 318.5m. He was trying to beat Mark Elliott who made a depth of 313m, but he had another goal which was to reach 320m Goals Easier Goal = Become the world's deepest diver by beating Mark Elliott at 313m (succeeded) Harder Goal = Get up to 320m (failed) You made a spelling mistake in your question. When you mean that kind of C, you say sea.

Does spinning water always spin in the same direction?

The direction in which water spins can be influenced by various factors such as the shape of the container, the initial motion of the water, and external forces such as wind or currents. In nature, water can exhibit different spinning directions depending on the circumstances.

What is the average temperature of salt water?

"Room temperature" is an informal substitute for the temperature value in "standard temperature and pressure", an internationally defined set of conditions. At present, this temperature is 25 degrees Celsius. Note that "salt water" has no influence on the answer; any other substance at room temperature would result in the same answer.

What is an Eskers?

An esker is a long, winding ridge of sand and gravel deposited by a melting glacier. It is typically formed in tunnels within or beneath the ice and can stretch for many kilometers. Eskers are a common feature in glaciated regions.

When was the most infamous tsunami ever?

The most infamous tsunami in recent history occurred on December 26, 2004, with the Indian Ocean Tsunami. Triggered by a 9.1 magnitude earthquake off the coast of Sumatra, Indonesia, it caused devastation across several countries and resulted in over 230,000 fatalities.

The shelf edge is the boundary between the continental shelf and the?

continental slope, where the sea floor steeply drops off to deeper ocean depths. It marks the transition from shallow continental waters to the deeper oceanic realm.

What is the largest watershed?

The Amazon River basin is considered the largest watershed in the world. It covers approximately 2.7 million square miles and spans multiple countries in South America, including Brazil, Peru, and Colombia.

How is a deep ocean current formed?

Deep ocean currents are formed by differences in water temperature and salinity, as well as by the topography of the ocean floor. Cold, dense water sinks and flows along the bottom of the ocean, while warm water rises and flows along the surface, creating a continuous circulation pattern. This movement of water is also influenced by the rotation of the Earth and wind patterns.

Has a tsunamis ever taken out a plane?

Yes, parked planes. I don't believe an earthquake caused tsunami has ever struck an airborne plane. These typically only rise a few meters out in the ocean. They surge higher over land, but still usually below treetop level--well below typical flying heights.

Is pH dangerous at 7.4?

A pH of 7.4 is considered slightly alkaline, and it is within the normal range for human blood pH (which is typically around 7.35 to 7.45). This pH level is not dangerous for most individuals, as the body has mechanisms to regulate and maintain a stable pH to keep us healthy.

What is a blue water sailor?

Crewmen aboard warships at sea; Brown Water Sailors operate Riverine Boats (Swift Boats, PBR's, Monitors, and Alpha Boats during the Vietnam War/Brown Water Navy disbanded in 1970 in Vietnam).

What is a halocline in oceanography?

In oceanography, a halocline is the vertical zone in the oceanic water column in which salinity levels change rapidly with depth, located below the mixed, uniformly saline surface water layer. A halocline can be found in countless locations around the world yet some of the most developed are located in the Atlantic Ocean where salinities can decrease by several parts per thousand from the bottom of the surface layer to depths of about 3,300 feet. The opposite of a halocline would be a pycnocline where, through depth, water density increases.

How are high islands formed?

Volcanic islands form when volcanic activity initiates on the sea floor. Over many years the rock formed by successive eruptions builds up, eventually breaching the surface to form islands. This can occur in two geologic settings: hot spots and oceanic subduction zones. With a hot spot, extra hot mantle material wells up in a plume originating near Earth's core. Some of this melts beneath the crust and the resulting magma rises up through the crust, erupting to form volcanoes. This is how the Hawaiian Islands formed. In an oceanic subduction zone, two plates consisting of oceanic crust collide. One plate slides under the other an into the mantle. Seawater trapped in the rock and sediment seeps into the hot mantle rock, altering the chemistry and allowing it to melt into magma. This then rises through the crust to form volcanoes. Many of the Aleutian Islands formed by this proceeds. A similar process can occur with an oceanic plate subducting under a continental plate, forming volcanoes along continental margins.

What are tsumamis?

A tsumami is a large amount of water arranged into a wave. It is triggered when a large earthquake displaces a large amount of water and sends it hurling towards land.

As the deep water wave gets close to land it picks up speed and gains height.

Linnaeus founded the science of?

He was known a the Father of Taxonomy and created binomial nomenclature, which is a 2 part scientific name written in italics or underlined, based on structural similarities of organisms. Genus is always capitalized and species is always lower case. Ex: Homo sapiens

The moon travels around the earth its gravitational force pulls on water making two kinds of tides what are the two tides?

The two types of tides created by the moon's gravitational pull on Earth's water are high tides and low tides. High tides occur on the side of Earth facing the moon and on the opposite side, while low tides occur at the points perpendicular to the moon.

Average depth of southern ocean?

The average depth of the Southern Ocean is around 13,100 feet (3,990 meters). This makes it one of the deepest oceans in the world, with significant variations in depth across its vast expanse.

What is the current use of the word pulchritude?

The word "pulchritude" comes from the Latin "pulchra," meaning beautiful. Thus, pulchritude is just a fancy, more Latin-rooted way of saying "beauty."
