### water:

Seawater
* Most seawater contains phytoplankton
  - has conductivity
  - passes through gills
* Some seawater contains minerals.
* Some seawater contains other minerals
  - valuable minerals
* Some seawater enters chambers
  - vacuum chambers
  - kills sea urchins
  - passes through membranes
* also contains hundreds of trace elements that are important in many biological reactions
  - lots of solutes in addition to salt
* can also create wetlands, especially in coastal areas that experience strong tide s
  - seep into groundwater and common problem in coastal areas
  - hold fewer dissolved gas molecules when it heats up
* consists of a small quantity of salt dissolved in water.
* contains a large quantity of dissolved salts therefore, has a high conductivity
  - excess salts, some of which pass straight through the gut without being absorbed
  - many soluble compounds in addition to salt
  - plenty of sulfate
* does indeed contain all the elements, but in extremely small amounts.
* expands in volume with increasing temperature.
* gets denser when it gets colder or saltier.
  - many advantages as an alternate, non-traditional source for coastal areas
* irrigates varieties of cotton and tomato plants that thrive on salty water.
* is collected from known depths using CTD-rosette sampling protocols.
* is full of ions that compete with calcium and carbonate
  - nutrients from winter mixing
  - given different names depending on the amount of solids dissolved in it
  - heavier because so many particles are dissolved in it
  - located in sea
  - measurable in an estuary diluted with fresh water derived from land drainage
* is pumped in and out, simulating the tide
  - into the mesocosm to provide the cod larvae with a source of planktonic food
  - salt water
  - saltwaters
* is slightly denser than fresh water
  - more viscous than fresh water
  - somewhat reluctant to take on more carbon dioxide than it already has
  - taken into a system of canals and is used to extend the many tube feet
  - the medium of transport and is propelled in and out of the sponge by ciliary action
  - used for cooling and well water injection
* potentially rich but currently limited source of fresh water and minerals.
* provides elements.
* rushes in to fill the space that was taken up by air.
* seeps down through cracks in the ocean floor and circulates deep into the ocean crust
  - through cracks in the ocean floor and is heated by warm rocks

### water | seawater:

Warm seawater
* Some warm seawater enters chambers
  - vacuum chambers
* expands and is thus less dense than cooler seawater.

### water:

Shallow water
* Most shallow water encourages root growth
  - provides habitats
* are preferred to lower the risk of predation, and for reproduction.
* can be quite dangerous for a large submarine
  - get deep and dangerous fast
* encourages growth
* is as dangerous as deep water.
* is located in lakes
  - ponds
  - pools
  - swimming pools
  - shallower before sunrise
* is used for puppies
  - tidal pools
* limit boat size on low tide.
* makes fish and invertebrates accessible.
* means tiger sharks.
* provides bass opportunity to feed, deep water close by an escape route from danger
* sloughs in meadows.

### water | shallow:

Shallow cultivation
* encourages seed germination and depletion of the soil seedbank.
* has the advantage of weed control with little or no use of herbicides.
* helps prevent injury to crop roots
  - the soil absorb and hold water
* is used to avoid harming roots
  - useful in removing small weeds
