meteoric dust. Eolian dust often also comprises sand-size particles. It is activated by whirlwinds originating from strong convection above the intensely
heated surface of deserts. ~eolian sediment.

dynamic topography chart of vertical variations of the sea surface, computed
with respect to a certain reference level, and based upon observations of the
depth distribution of temperature and salinity. From these observations the
specific volume of the water can be calculated, and this again gives the
height of the sea level above a certain reference level. If this reference level
were horizontal, the real topography would be obtained, but in practice at
best only an approximation is obtained.
