Geological period, covering 280 to 225 Million years, representing the last pert of the Palaeozoic era.
Industry:Earth science
Geological period, covering 65-2 Million years ago, representing the first (major) part of the Cenozoic era.
Industry:Earth science
Geomorphic feature whose origin is related to the processes associated with glacial meltwater.
Industry:Earth science
Habitat found along a coastline and is covered with ocean salt water for all or part of the year. Examples of this type of habitat include tidal marshes, bays, lagoons, tidal flats, and mangrove swamps.
Industry:Earth science
Heat energy that can be felt or measured directly with a thermometer.
Industry:Earth science
High pressure system that develops over the western subtropical North Atlantic. Also called Azores High.
Industry:Earth science
Horizontal deltaic deposit of alluvial sediment composed of fine silt and clay.
Industry:Earth science
Horizontal length scale of a rotating system measuring the distance over which the gravitational tendency to render a free surface flat is balanced by a tendency of the Coriolis acceleration to deform the surface. Also called the deformation radius or Rossby radius. In the shallow water approximation, the Rossby deformation radius is R = c/f in which c=(gH)^(1/2) with g the acceleration due to gravity and H the mean depth of the fluid. In stratified fluid, the appropriate length scale is called the internal Rossby deformation radius, and is given by R = ND/f in which N is the buoyancy frequency and D is a characteristic vertical length scale. At the equator, the effect of \beta (the meridional gradient of the Coriolis parameter) determines the equatorial Rossby deformation radius R=(c/\beta)^(1/2), and the equatorial internal Rossby deformation radius R=(ND/\beta)^(1/2).
