What an aquifer is
By: D. Vogt
An aquifer, essentially, is an underground water reservoir. They are particularly important geological phenomena because large aquifers can be rich sources of very clean water for human habitation above. One of the world's largest aquifers, the massive Ogallala Aquifer, lies beneath the Great Plains and...

An overview of black smokers
By: Judith Willson
Hot springs on the ocean floor were only discovered in the 1970s and are among the most spectacular features of the deep oceans. The hottest of these hydrothermal vents are the famous black smokers with water coming out at temperatures exceeding 350 degrees Celsius. Due...

The structure of the ocean crust
By: Judith Willson
The portion of the earth’s crust that lies underneath the oceans tends to be newer than that of the continents. The fast spreading from the ocean ridges creates new oceanic crust so fast that it is measurable even in human terms: one to twenty...

The fundamental difference between aquatic and marine life is that aquatic life occurs in any body of water, whereas marine life specifically lives in saltwater environments. Marine organisms often have special adaptations that allow them to thrive in this particular type of aquatic environment. Aquatic...
An overview of ocean biogenic sediments
By: Judith Willson
The sediments in the ocean, which sometimes later become rocks, come from two main sources. Terrigenous sediments originate from weathering on land and biogenic sediments consist predominately of the skeletons of tiny marine organisms. Biogenic sediments can provide answers about the ecology, climate and chemistry...
What are ocean long waves
By: Judith Willson
Ocean long waves are disturbances caused by the wind that travel an extremely long way and have a profound effect on ocean circulation. These can be barotropic waves, which propagate along the surface, and baroclinic waves, which move long a sharp density gradient. Two of...
