Oceanographic Survey
Oceanic Survey: is the measurement and study of underwater features and characteristics to understand physical processes in the ocean, develop detailed seafloor images, and support activities like navigation, marine construction, and resource exploration. Surveys use methods such as sonar for bathymetry (seafloor mapping), while other techniques measure oceanographic properties,
Acoustic Doppler Current Profiler (ADCP)
is an
instrument that uses the Doppler effect of sound waves
to measure water speed and direction at various depths
within the water column. By emitting sound pulses that
reflect off particles in the water, the ADCP analyzes the
frequency shift in the returning signals to calculate
current velocity deployment for current speed and
direction (vertical profiles, tidal cycle, seasonal
variations)
Tide gauge
is a device that precisely measures
changes in sea level relative to a fixed point on land,
used to monitor tides, determine mean sea level, and
detect changes like storm surges and
tsunamis. Modern versions use sensors like radar or
pressure sensors to continuously record water levels,
providing critical data for coastal management, harbor
operations, and understanding sea level rise influenced
by climate change.

The WRB
plays a critical role in our Dynamic Under Keel
Clearance system, this system allows the safe transit
of deep draft ships or ships in heavy weather when
navigating the harbour entrance
Hydrographic Survey
is the science of measuring and
describing underwater features, using technologies like
sonar, lidar, and GPS to map the topography of the
seabed and other marine environments.
Bathymetric survey
is the scientific process of
mapping the depths and topography of a body of
water, akin to mapping land elevation on land. The
process involves using equipment like multibeam
echosounders and bathymetric lidar to measure water
depths and create detailed underwater maps, often
using sound waves or light pulses and GPS for precise
positioning
