This function assembles vectors of pressure and velocity, possibly also with shears, salinity, temperature, etc.
as.ladp( longitude, latitude, station, time, pressure, u, v, uz, vz, salinity, temperature, ... )
longitude in degrees east, or an
latitude in degrees east (use negative in southern hemisphere).
number or string indicating station ID.
time at the start of the profile, constructed by e.g.
pressure in decibars, through the water column.
eastward velocity (m/s).
northward velocity (m/s).
vertical derivative of eastward velocity (1/s).
vertical derivative of northward velocity (1/s).
salinity through the water column, in practical salinity units.
temperature through the water column.
optional additional data columns.
An ladp object.
