Estuaries Flashcards
Estuary
body of water partially surrounded by land where freshwater and sediments from a river mix with oceanwater
Delta
area of sediment deposit as a river flows to the ocean
Progradation
movement of sediment and its deposition further away to change structure of river/sea bed
- progradation domination (when estuary becomes delta)
Transgression
change in sea level
Swell
mature wind waves of 1 wavelength that form orderly undulations of the ocean surface
Anoxic sediments
sediments with reduced O2, reduced circulation, and decay of organic matter
black in color, rottonegg smell
little biota
Intertidal region
has high tide and low tide
Subtidal region
completely submerged
epibenthos
animals/plants that sit on surface of sediments
