Amictic
no mixing
Holomictic
Lake mixes entirely at least once a year
Dimictic
holomixis occurs twice per year. Usually ice covered
Polymictic
mixes often - with storms or daily.
Monomictic
one distinct period of mixing
Meromictic
lake mixes partially at least once a year
Cold Monomictic
ice free but cold in summer
Warm Monomictic
not cold enough for winter ice, usually
Albedo Effect
Ice reflects light/heat. less ice leads to more warming which leads to less ice
Thermocline
Temperature gradient
Chemocline
Chemical gradient
Halocline
salinity gradient
Pycnocline
density gradient (either with temperature or salinity)
Mixolimnion
Section of a meromictic lake that mixes
Monimolimnion
Section of a meromictic lake that does not mix
Meromixis Causes - Ectogenic
outside sources (ocean intrusion, road salts)
Meromixis Causes - Biogenic
organic salts from decomposition
Meromixis Causes - Crenogenic
salt springs
