Mixing Types
|
Salt-wedge
Poorly Mixed Well-mixed Fjord (saltwater sits at the bottom and in extreme cases forms a brine pool) |
|
|
Clines
|
Thermocline (it suddenly gets colder a few meters down)
Halocline (salinity increases suddenly with depth) Pycnocline (density follows a similar curve to the Halocline) |

|
Interesting Recent Stuff I
|
Mobile Bay Jubilees (recorded since 1912, could be benthos trying to get oxygen at the surface but get stranded on the shore)
Hydrothermal Vents (1979, minerals leak from the earth's crust and sustain ecosystems dependent on chemosynthetic rather than solar energy) |
|
|
Interesting Recent Stuff II
|
Horseshoe Crab (1960s-70s, Limulus Ameobocyte Lysate is discovered in horseshoe crab blood)
Chemosynthesis in GOM (1984, Hydrogen Sulfide, methane and hydrocarbons seep into brine pools, bacteria take this in at 3200 meters below sea level in the GOM) 2007, Blacktip parthenogenesis (sexually having offspring with no mating) reported |
|
|
Interesting Recent Stuff III
|
Algal products (Carageenan in ice cream, toothpaste and other products)
