So you can have more than 1 state at a time…and why ice floats!
Why does ice float – ice is less dense than (liquid) water
Temp., Salinity and Density have a complex relationship – you can
have the SAME density at different concentrations of Temp. and salinity.
3. The DEEP ZONE (80% of all ocean water) is the layer below the pycnocline (but little change occurs here).

Contrasting features of shallow and deep ocean water
Different wavelengths of light produce different colors. As they are
“absorbed/scattered” in the water the colors reach different depths.
Why buy a RED wetsuit?
“regular” ocean light penetration – blue dominates
strobe light penetration – blue HUES (+ other colors)
Relationship between water depth and sound velocity.
