Oceanography

Sylvia Earle studies various sea creatures, but she is particularly known for her work with sharks, jellyfish, and deep-sea creatures. She has spent a significant amount of time exploring and researching these animals to better understand their behavior and importance in marine ecosystems.

The first oceans began to form around 4 billion years ago. They formed from the outgassing of water vapor from volcanoes as well as water transported to the surface via asteroids and comets. As the Earth cooled water vapor in the atmosphere turned into clouds which rained down the water that would create the oceans.

The current turnover worldwide is constantly changing due to various factors such as economic conditions, consumer behavior, and industry trends. As of the latest available data, global turnover across all industries is estimated to be in the trillions of dollars.

The earth formed around 4.2 billion years ago, but it would have been too hot for water to liquidize at that point.

I think around 3.8 billion years ago, but this is easy to look up online.

No. New Orleans was devastated by a hurricane in 2005.

Speaking in general terms, the high and low tides occur twice daily.

It is unlikely for Montreal to experience a tsunami as it is a landlocked city located far from significant tectonic plate boundaries where tsunamis typically occur. Tsunamis are more commonly associated with coastal regions near major fault lines or volcanic activity.

The ocean floor near the center slit typically shows deeper depths and a more pronounced trench-like formation compared to the ocean floor near the side slit. The center slit is often associated with tectonic plate boundaries, resulting in more significant geological activity and topographical features. In contrast, the side slit may exhibit a shallower gradient and less dramatic relief due to its location away from the main tectonic activity.

ODAS stands for "Ocean Data Acquisition System". This is a type of buoy that obtains scientific data on sea conditions at the buoy location automatically. Typical examples are yellow, with instrumentation and solar power panels installed that will automatically sample local sea conditions such as water temperature, air pressure and temperature, wind speed and direction, average wave height and period.

Water depth does not affect wave height in deep water. In deep water, the wave height is determined by the wind speed, duration, and fetch (distance wind has traveled over water).

Another name for thermohaline circulation is the ocean conveyor belt. This circulation pattern involves the movement of water around the world's oceans based on differences in temperature and salinity.

A tsunami is one or more water waves caused by a large displacement of water. This is typically in an ocean but the large lakes of the world are big enough to allow a tsunami to form. Tsunamis are usually caused by undersea earthquakes. It is rare, but a tsunami can be cause by an avalanche or landslide that displaces a large volume of water or even an asteroid or comet hitting the ocean.

A tsunami commonly forms when there is a dramatic uplift or fall of the ocean bottom associated with a submarine earthquake. In that case a large volume of water suddenly drops and surrounding water rushes in or a large volume of water is uplifted and water flows away from the area. Tsunami waves are not like normal ocean waves which do not result in a net transport of water. When a tsunami wave forms it is because a large volume of water is entering or leaving an area of the ocean. For this reason the propagation of a tsunami is different and very fast, hundreds of kilometers per hour.

Tsunamis form wherever an undersea earthquake can form, so they are particularly common at the boundary of the Earth's tectonic plates. These plates have areas where they are particularly active, the Pacific "ring of fire" being the most well known.

Typically a tsunami exhibits several waves in succession separated by minutes or hours. This will depend on the character of the original disturbance being fast or slow or limited to a small area or large. When tsunamis propagate across the ocean, they have a small amplitude a few inches (centimeters) high but they extend for hundreds of kilometers. Since there is actual flow of of a large volume of water associated with a tsunami, this height increases as the volume of water approaches the shallower coastal region. At the coast, the height is a fraction of a meter (a few feet) to hundreds of meters.

"Blue Water High" featured a cast of young Australian actors, including Chris Foy, Sophie Luck, Tahyna Tozzi, and Mara Scherzinger, among others. These actors portrayed the group of aspiring surfers and students at Solar Blue, a prestigious sports academy.

The Southern Peru tsunami on June 23, 2001, hit the coast in the afternoon after a powerful earthquake struck near the southern city of Arequipa. The tsunami caused widespread damage along the coast and resulted in numerous casualties.

The earth is going through a period of warming, known as global warming. As the earth becomes warmer the Ice in very cold parts of the world begins to melt. Instead of floating on top of the water in solid form, this now melted water goes (diffuses) into the ocean, causing the seal level to rise.

It depends on the depth. On deep oceans it can hit 500 mph. Near the land it slows down to 20 or 30 mph.

It is important to note that the 500 mph is simply a theory, there is no method to truly measure the speed of the wave. Also, if you follow the above link it explains that when the tsunami approaches any land it slows to 20-30 mph. This would even further refute the 500 mph.

Yes, mili is 10-3 and micro is 10-6 so mili is bigger.

As the Earth turns on its axis, the moon moves around the Earth. This causes the tidal bulges to travel from east to west. Every place along the seashore has two high tides and two low tides daily. All parts of the oceans pass under the moon in 24 hours and 50 minutes. In one fourth of this time, the tides change. So, tides change approximately every 6 hours and 12.5 minutes. From one high tide to another high tide is 12 hours 25 minutes. it can be either two answers. 1. 6 hours and 12.5 minutes (6 hrs and 13minutes if rounded) 2. 12 hrs and 25 minutes.

The type of wave that has a trough and crest is called a transverse wave. In a transverse wave, the particles of the medium move perpendicular to the direction of the wave propagation, resulting in the formation of crests and troughs.

Tsunamis do not have a purpose in the traditional sense. They are natural phenomena caused by underwater disturbances like earthquakes, landslides, or volcanic eruptions. While they can have devastating impacts on coastal communities, they are simply a result of tectonic and geological processes.

Sea pens are marine cnidarians that have a soft cylindrical body with a feathery, brightly colored polyp at one end. They are named for their resemblance to old-fashioned quill pens. Sea pens are typically found in deep-sea environments and are filter feeders, using their polyps to capture plankton from the water.

Tsunamis usually occur after earth surface disturbances, (of course these disturbances can occur on land or under the sea). They are not seasonal and hence there isn't a time of year they are more likely to occur.

The Great Lakes have an outlet: The Saint Lawrence. The reason why most lakes are not salty is because they have an outlet so the minerals do not accumulate. On top of that, they are well above sea level, so there is no chance of saltwater intrusion.

I got this from another website, but I am not sure if it is accurate! Apparently kelp is in shampoo, algin is in salad dressing, agar is in yogurt, and coral is in sunblock! Hope I helped!

Scientists use models to simplify complex systems, making it easier to understand and predict how they work. Models help researchers test hypotheses, make predictions, and explore different scenarios in a controlled environment before conducting actual experiments or observations.
