An arbitrary level conforming to the lowest tide observed at a location, or somewhat lower.

The preferred benchmark in Germany is Lowest Astronomical Tide (LAT).

The lowest tide level that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions.

(l) height of the wreck above or below the surface of the water at lowest astronomical tide;

height of the wreck above or below the surface of the water at lowest astronomical tide;

(l) height of the wreck above or below the surface of the water at lowest astronomical tide;

(l) height of the wreck above or below the surface of the water at lowest astronomical tide;

Lowest Astronomical Tide (Lat) The lowest tidal level which can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions.

This level approximates to Lowest Astronomical Tide (L.A.T.) which is the lowest level that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions.

lowest astronomical tide: (LAT) - the lowest tide level which can be predicted to occur under average meterological conditions and under any combination of astronomical conditions.

Highest astronomical tide (HAT) is the highest level, and Lowest astronomical tide (LAT) the lowest level that can be expected to occur under average meteorological conditions and under any combination of astronomical conditions.
