spring tide

Biology; Ecology

The high and low tide preceding a neap tide. Combined tidal pulls from Sun and Moon make the tide rise higher and fall lower than normal.

resuspension

Biology; Ecology

Dispersion of particles back into water, as when wave action or dredging stir up sediments that had fallen out of suspension and settled.

zooplankton

Biology; Ecology

Plankton that do not produce their own food, as phytoplankton do. In size they fall between phytoplankton and larger organisms like fish.

filter feeder

Biology; Ecology

An organism that screens its food from water. Baleen whales do this by forcing seawater past the baleen plates they use instead of teeth.

geostrophic winds

Biology; Ecology

Global winds; they blow above 1,000 meters up and are driven more by pressure/temperature factors than by surface features or conditions.

throwaway mentality

Biology; Ecology

The belief that we can use up resources, throw away the remains, and move on to fresh ones. It is a holdover of the frontiersman mindset.

eurybathic

Biology; Ecology

Able to tolerate different depths in water (like a sperm whale, which can ride on the surface or dive deeply). Contrast with Stenobathic.
