Term
plate tectonics
Definition
the process in which large sections of the earth's crust move about
Term
passive continental margin
Definition
one that is on the "trailing edge" of a continent and therefore has little geological activity
Term
active continental margin
Definition
one that is colliding with another plate and therefore has a lot of geological activity
Term
semidurnal tide
Definition
a tidal pattern with two high and two low tides each day
Term
diuranal tide
Definition
a tidal pattern with one high and one low tide each day
Term
mixed semidiuranl tide
Definition
a tidal pattern in which two successive high tides are of different heights
Term
Coriolis effect
Definition
as a result of the earth's rotation, anything that moves large distances on the earth's surface tends to bend to the right in the Northern Hemisphere and to the left in the Southern Hemisphere
Term
Osmosis
Definition
The movement of water from high to low concentrations across a membrane
Term
active transport
Definition
the transfer of substances across membranes by a cell against a concentration gradient
Term
hemoglobin
Definition
a blood protein that transports oxygen in many animals; in vertebrates it is contained in erythrocytes, or red blood cells
Term

plankton

 

Definition
primary producers (phytoplankton) and consumers (zooplankton) that drift with the currents
Term
primary production
Definition
the conversion of carbon from an inorganic form, carbon dioxide, into organic matter by autotrophs - that is, the production of food
Term
anadromous fishes
Definition
those that migrate from the sea t ospawn in fresh water
Term
catadromous fish
Definition
those that migrate from fresh water t ospawn at sea
Term
tidal range
Definition
difference i nwater level between successive high and low tides
Term
chemosynthetic bacteria
Definition
autotrophic bacteria that use energy contained in inorganic compounds rather than sunlight to make organic matter
Term
detritus
Definition
particles of dead organic matter
Term
deposit feeders
Definition
animals that feed on organic matter that settles in the sediment
Term
suspension feeders
Definition
animals, including filter feeders, that feed on particles suspended in the water column
Term
resource partitioning
Definition
the sharing of a resource by two or more species to avoid competition
Term
nitrogen fixation
Definition
conversion of nitrogen gas (N2) into nitrogen compounds that can be used by primary producers as nutrients
Term
indo-west pacific region
Definition
the tropical indian and wesern and central pacific oceans
Term
entrophication
Definition
increased growth of algae as a consequence of excess nutrients
