Aquifer Compaction
Fine-grained sediments (clays and silts) within an aquifer system are the main culprits in land subsidence due to groundwater pumping. Fine-grained sediments are special because they are composed of platy grains. When fine-grained sediments are originally deposited, they tend to be deposited in random orientations.

Brackish Pond Community
Looking from an observation deck, at Rookery Bay National Estuarine
Research Reserve, onto a flock of birds resting in a brackish (somewhat salty)
pond community. Mangrove islands grow inside and along the edges of the
pond.
