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.

What is the definition of mesotidal?
Mesotidal I think is not a noun. It is a characteristic of a coast. For instance, the Eastern Wadden-sea (Netherlands) is mesotidal: the difference between water height at high tide and at low tide is in the mesotidal range. The ranges are approximately as follows, but different sources give different limits: Microtidal: under 2m Mesotidal: 2-3?m Macrotidal: over 3?m http://fds.oup.com/www.oup.co.uk/pdf/0-19-852508-7.pdf Box 1.3 gives the tidal ranges.
It says here mesotidal is 2-4m. Macro Tidal - 4m and above Micro Tidal - 2m and below
Meso Tidal- Between 2 - 4m

What do call salt water and fresh water meet?
Fresh water and salt water meet at a river's mouth, where fresh water becomes salty and is known as brine. This mixing often occurs in an estuary, where the river widens.
What is oceanography what was learned from the challenger expedition?
Oceanography is the exploration and scientific study of the oceans and ocean floor.
The Challenger expedition of was a scientific exercise that made many discoveries to lay the foundation of oceanography.
Scientists who study oceanography rely heavily on knowledge from all of the following areas except?
meteorology
What is the pressure at the 500 m below the seawater surface?
Every 10 meters you go down, the pressure increases by about 1 bar. You must also consider the air pressure, which is about 1 bar. You can base your calculations on that.
When did the group Blue October release 'Into the ocean'?
The group Blue October, an American rock band, released the song 'Into the Ocean' in 2006. This song can be found on the album Foiled. Although the song itself peaked at #53 in the Billboard Hot 100, the video hit number one on V-Spot countdown by VH1.
Where can you buy CDs with ocean sounds?
There are a number of different collections of ambient sounds sold on CD, typically as a relaxation or sleep aide. Amazon sells many of these different products, as do many retailers of CDs such as music stores. Also, big box stores like Walmart may carry these CDs.

Can tsunamis travel across the ocean without losing energy?
Yes, they can. Tsunamis recollect their energy when they are traveling across the ocean.
How water temperature and salinity affect water density and how does this impact a diver?
Density falls as temperature rises, but increases as salinity rises.
The only real effect on a diver is that of cold; unless you dive through a halocline (sudden boundary with much more or less salty water), which may affect your buoyancy.
I've seen a photograph of a rather impressive halocline in a cave in which incoming fresh water from inland flowed onto sea-water. The diver was standing with his waist just below the boundary, and the optical effect of the halocline made him appear to be standing with his upper body in air. In fact the passage was filled completely with water!
What is the process of the ocean's water slowly rising to reach high tide is called?
Flood tide is when the ocean's water slowly rises to reach high tide.
Why it is so easy swim in sea water than swimming pool?
this is because the sea is full of salt (as most people figure out after swallowing most of it) which acts as a buoyant that's why in the dead sea you float a lot easier as it is full of salt. in the swimming pool it doesn't contain as much salt.
hope this helps :)
Does glaciology is an earth science branches?
maybe, if earth science is the same as environmental science, which i think it is.
It is highly unlikely for a tsunami to hit Utah as it is a landlocked state with no direct access to the ocean. Tsunamis are caused by underwater earthquakes, volcanic eruptions, or landslides that displace large bodies of water in oceans or seas. Utah's geographic location reduces the risk of being affected by a tsunami.
The large circular-moving current systems that are within an ocean basin are called?
'gyres' there are 5 main gyres; North Pacific, South Pacific, North Atlantic, South Atlantic and the Indian Ocean.
How is red a good camouflage color in the ocean?
Red is not a good camouflage color in the ocean because it is easily visible in water due to the way light penetrates and gets absorbed. In fact, red can make a creature more noticeable to predators. Fish and other marine creatures typically have colors that help them blend into their surroundings, such as blue or green.
What the steep incline at the edge of the continental shelf called?
The edge is called the shelf break. The actual declining shelf is called the called the continental slope.
Where do tidal waves originate where do they end?
Tidal waves originate deep within the ocean and end once they reach the coast. They are typically caused by large earthquakes which send shock waves outward from the epicenter.
When salt water evaporates does it turn in fresh water?
Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
