Ocean beds are fascinating in their own accord. Their very depth is what makes them so enchanting. Most oceans go up to depths of several thousand meters. But what is the deepest part of the ocean exactly? Scientifically speaking, it refers to the maximum depth of a point that can be accessed or defined.

Every such deepest part ocean is referred to as deep trenches. But if we were to consider deepest depth of the ocean, we’d be truly amazed. Here is a list of various points that mark deepest points of oceans.

1. Mariana Trench

Better known as the deepest point on earth’s surface, this trench lies in Pacific

The movement of ocean water is one of the two principal sources of discrepancy between dead reckoned and actual positions of vessels. Water in motion is called a current; the direction toward which it moves is called set, and its speed is called drift. Modern shipping speeds have lessened the impact of currents on a typical voyage, and since electronic navigation allows continuous adjustment of course, there is less need to estimate current set and drift before setting the course to be steered. Nevertheless, a knowledge of ocean currents can be used in cruise planning to reduce transit times, and current models are an integral part of ship routing systems. Oceanographers have

Environmental Impacts

Water Levels

The primary effect of the Aral Sea desiccation has been the significant loss of water in the sea. The water level has dropped approximately 23 meters since the onset of its primary sources of water being diverted (Zavialov 2005). Although the water level has fluctuated up to a few meters in the past due to natural variability in the water flow from the rivers, by 1970, the water loss exceeded the limit of natural water level variation that has occurred in the past. 

The water budget is determined by several components: Inflow from the river, evaporation, precipitation rates, and groundwater inflow. Net evaporation is defined as the difference between evaporation and precipitation at the surface (Micklin

Our planet's magnetic field is in a constant state of change, say researchers who are beginning to understand how it behaves and why.

Every few years, scientist Larry Newitt of the Geological Survey of Canada goes hunting. He grabs his gloves, parka, a fancy compass, hops on a plane and flies out over the Canadian arctic. Not much stirs among the scattered islands and sea ice, but Newitt's prey is there--always moving, shifting, elusive.

His quarry is Earth's north magnetic pole.

At the moment it's located in northern Canada, about 600 km from the nearest town: Resolute Bay, population 300, where a popular T-shirt reads "Resolute Bay isn't the end of the world, but you can see it from here." Newitt stops there
