Estuaries
This habitat within an estuary is the lowest in elevation and is always filled with water.
What is the channel?
Isolated pockets of seawater in the intertidal zones of rocky beaches
What are tide pools?
The majority of the deep sea is in this zone.
What is the abyssal zone?
The polar region that is a frozen ocean surrounded by continents.
What is the Arctic?
The amount of time necessary for the total volume of water to be completely replaced in an estuary.
What is the flushing time?
This intertidal zone has the lowest diversity.
What is the upper interidal?
The only deep-diving research HOV submersible in the U.S.
What is Alvin?
Permanent sea ice
What is fast ice?
What is a salt wedge?
These species are the first to move into a newly disturbed habitat in the process of ecological succession.
What are pioneer/primary species?
The tendency for organisms to grow large in the deep sea.
What is gigantism?
A low-density and low salinity layer that forms near the surface during the spring and releases ice algae.
What is meltwater?
An area of water that has been completely depleted of oxygen due to eutrophication.
What is a dead zone?
This intertidal zone has the highest relative levels of competition.
What is the lower interidal?
As depth and pressure increase, the solubility of this compound increases.
What is oxygen?
The measure of reflectiveness of the sun's rays.
What is albedo?
An organism that can only tolerate a narrow range of salinities would be considered to be this.
What is stenohaline?
This intertidal zone is dominated by barnacles.
What is the middle intertidal?
What is terrigenous?
The compounds that are breaking down our ozone layer and were banned in 1990 by the Montreal Protocol.
