epifauna
therefore differs from mixing, where the two water masses exchange properties. In case of entrainment there should be either advection or a gradual
shift of the place of the boundary surface.
entropy thermodynamical quantity: the energy (in joules) absorbed by a
reversible process divided by the absolute temperature (in Kelvin).
environment the sum of conditions and objects (living and nonliving) that act
upon organisms or groups of organisms and determine their form and/or
functioning.
environmental monitoring ~monitoring.
environmental stress ~stress.
Eocene ~geological time scale.
eolian sediment (or aeolian sediment) after Aeolus, the Greek God of the winds.
Wind-blown sediment of volcanic (volcanic ash) or nonvolcanic (sand,
desert dust) origin that often is transported over large distances and eventually settles on land, e.g., dunes or in the ocean. Well known is the reddishbrown quartz originating from weathering of continental rocks. Other terrigenous minerals, such as calcite and biogenic components, notably phytoliths, freshwater diatoms and even fungus spores also occur in atmospheric dust. Fine particles are carried as "aerosols" over the ocean; upon deposition and vertical settling through the oceanic water column the sediment
accumulates on the sea floor at rates in the order of about one millimeter per
thousand years. Such red clays, undiluted by marine biogenic (calcite, opal) or
turbidite inputs only occur in restricted areas of the seafloor, remote from the
continents. Common components of eolian sediments may form the clay
minerals chlorite, illite, kaolinite and montmorillonite (smectite). ~dust.
ephyra pre-stage of medusa.
epibenthos benthic organisms living on the surface of the benthos. ~benthos.
epicenter the location on the earth's surface below which an earthquake originates. Compare hypocenter.
epidermis outermost tissue layer of an animal, in invertebrates only one celllayer thick.
epifauna bottom animals that live on the surface of the sea floor, such as most
crabs, shrimps and starfish; opposite of endofauna.
