The science of measuring depths of the oceans, lakes, seas, etc.

measurement of depths of bodies of water. Read more in the NG Education Encyclopedia

The study of water depths.

The water depth relative to sea level. Depth values may be either negative or positive, but should all be understood to be negative. Depths are almost always derived indirectly by measuring the time r [..]

Measuring the depths of large bodies of water, such as oceans and lakes.

The science of measuring the depth of the sea and other large bodies of water. Also refers to the information derived from such measurement, often presented in the form of a bathymetric map or nautica [..]

The study of water depths. Benguela current

the variation in depth of a water body, such as an ocean or a lake. Bathymetry is usually shown using contour lines of equal depth, or isobaths [bathymetric]

(n) measuring the depths of the oceans

charting of the sea floor using water depth measurements

the study and mapping of sea floor elevations and changes in water depth due to structures that rise up into the water column.

The measurement of DEPTHS of water in OCEANS, SEAS and lakes; also the information derived from such measurements.

the study of water depth and seafloor relief; a bathymetric map shows seafloor terrain as contour lines (called depth contours or isobaths)

The measurement of depths of water in oceans, seas, and lakes; also information derived from such measurements.

The topography of the ocean floor.

Science of measuring water depths (usually in the ocean) to determine bottom topography.

The study and mapping of sea-floor topography.

Measurement of the ocean depths 

The science of measuring ocean depths to determine the topography of the sea floor.

The measurement of depths of water in oceans, seas, and lakes; also information derived from such measurements. Topography of the ocean floor indicated by depth contours drawn at regular intervals.

The science of the measurement of marine depths. Submarine relief.

Bathymetry is the topography of the floor of the ocean. It also refers to the measurement of the depth of the oceans.

 Measurement of the ocean depths.

The determination of ocean depths. The general configuration of SEA FLOOR as determined by profile analysis of depth data.

The measurement of depths of water in oceans, seas and lakes; also the information derived from such measurements.

The measurement of ocean depth.

the topography of the seabed

The varying physical characteristics - including depth, contour and shape - of the bottom of the Bay and other bodies of water.

Bathymetry is the study of underwater depth of lake and ocean floors. The information for bathymetric maps today usually comes from an echosounder (a sonar mounted under a boat which sends a beam of sound downward at the seafloor and measures the time it takes for it to bounce off the floor and return) or from remote sensing LIDAR/LADAR systems (sa [..]

The science of measuring depths of the oceans, lakes, seas, etc.

The measurement of water depths in oceans, seas, and lakes; also information derived from such measurements.

the measurement of depths of water in oceans, seas, and lakes

The study of the underwater depth of lakes or ocean floors.

the measurement of deep sea soundings
