Chapter 22 the water planet

At what latitudes is the melting of sea ice most likely to be important in decreasing salinity below 33 ppt?

Between 60° and 90° north. Low salinities between about 0°and 10° south are due to several large rivers entering the ocean and not due to melting of sea ice.


Chapter 22 the water planet

Explain how electrical conductivity could be used to determine the mass of calcium ions in a sample of seawater when the mass of the whole sample is known.

As salinity increases, electrical conductivity also increases. Conductivity is used to measure total salinity. Salinity is then used to calculate the total mass of ions present. The various ions in seawater exist in constant proportion relative to each other. The mass of calcium ions is therefore determined by multiplying the total mass of ions by the percentage of seawater that consists of calcium ions.


Chapter 22 the water planet

Compare the food source of a clam that lives in shallow water near the shoreline with the food source of a clam that lives near a black smoker vent in the deep sea.

The base of the food chain in shallow water is phytoplankton that get their energy for photosynthesis from sunlight. Near black smoker vents, the base of the food chain is bacteria that get their energy for chemosynthesis from dissolved hydrogen sulfide gas released from the vent.
