From the Deck to the Seafloor

Human is known for their minds, this genius mind has equipped him with a number of technologies to keep their territories safe. They have succeeded well in securing the land and sky boundaries from all known predators, so why to pull their hand in securing their ocean boundaries.

Many companies have reached out with the latest oceanographic and marine scientific research equipment. These ocean survey equipment are boon to mankind which is self-sufficient to protect their territories. Exclusively one can surf in the list of ocean survey equipment which is easily available in the company catalogs.

In order to survey the majority of the navigable waterways, these ocean survey equipment will help a lot to collect precise and accurate data. These companies stand out to provide their service internationally.

To study the ocean bed through all angles you can take help of these ocean survey equipment. Some of them which are commonly used are Acoustic Doppler Current Profilers, Acoustic Releases system, Conductivity, Depth and Temperature Sensors, Current Meters and Profilers, Meteorological Equipments, Sound Velocimeters, and Tide Gauges. These ocean survey equipment are easily available for sale or on rental.

Out of all these Acoustic Doppler Current Profilers is in great demand. It is often referred with an acronym ADCP. Researchers use this ocean survey equipment in measuring the water flow across an entire water column. Currently, it is the most intelligent river system used worldwide. An Acoustic Doppler Current Profiler is anchored to the seafloor to measure the current speed not just at the bottom but also all the way to the surface. This instrument can be mounted horizontally to the seawalls or bridge pilings on rivers or canals.

Work Flow

It follows the Doppler Effect to measure the current flow. It measures the water current with sound waves because sound waves have high frequency or pitch when it moves towards you than when it moves away. As the sound waves travel, they reflect back to the instrument which is used for measuring the current speed.

Features

Acoustic Doppler Current Profiler is highly pscienticen, capable and versatile equipment. They are designed in such a way that they can fit any configuration you want then it might be for hydrology or oceanography or harbor monitoring. It often comes with all standard features as specified but additionally one can add optional features too.

Standard features:-

1. 0.25, 0.5 and 1.0-Mhz models.
2. Up to 180m profiling, ranges can be done.
3. GPS inputs and bottom tracking.
4. Compass and 2-Axis tilt sensor.
5. ADCP software.
6. Low power consumption.
7. Temperature sensor.

Optional Features:-

1. Seabird Microcat CT Sensor
2. Optical Backscatter Sensor (OBS)
3. Internal Recording
4. Pressure Sensor
5. Directional wave measurement capabilities.

Founded as most Advantageous

1. It has substituted the use of long strings of a current meter in past.
2. Highly sensitive to measure small-scale currents.
3. It is skilled to measure the absolute speed of the water.
4. It can measure a water column which is up to 1000m long.
