Bathymetric surveying involves measuring the depths of a riverbed or other body of water. This survey produces the map showing spot elevations and contours of the riverbed in relation to the mean sea level. Bathymetric surveying statistics also informs the people living in certain areas of any potential or ongoing coastal erosion, rises in sea level and sinking land spots. These charts produce results to make navigation above or below the water safer. Once completed, they typically show seafloor relief or terrain as contour lines. These lines are called depth contours or iso-baths.

Bathymetric surveying has been used since the 1930s. They have become more accurate through innovation and new technology and have spawned great aspects of studying. The study of oceans, rocks and minerals on the ocean floor and the study of underwater earthquakes or volcanoes are just a few examples. Such studies and research are fundamental components in ensuring the safe transport of people and goods around the globe. And there are different methods in which one can receive the best results for their bathymetric survey.
It is important for land developers to record and have knowledge of oceanic trends, including water temperature, wave occurrences and aspects of the ocean or seafloor. Doubly important due to the rise of climate change. Underwater rocks, minerals and fault lines are important for developers to use when deciding exact building locations near any aquatic areas including lakes.
Bathymetric surveying has many uses for people throughout Brooklyn, NY. Some of the more prominent ones are calculating depth contours, how curved a body of water’s floor is and the depth of the floor. Scientists use satellites to get the most accurate results. However, we do not have those means, but it doesn’t mean we get results that are inaccurate. We are just surveying land on a smaller scale. A bathymetric survey has the ability to detect the subtle variations in sea level caused by the gravitational pull of ridges, undersea mountains, and other masses found in the ocean. Sea level, on average, is higher over mountains and ridges than over trenches and abyssal plains. Bathymetric surveying is quite common in Brooklyn, since there is plenty of water surrounding the borough. So if you need this survey done, then please reach out to us today!
Before we get to the methods we use for a bathymetric survey, let's look at the different types of research that utilizes this sort of survey.

As professionals in this field, we understand the need to utilize different methods for different tasks and applications when it comes bathymetric surveys. Here is a more in-depth look at these various methods and their utilization in the survey field.
This is a survey that is typically done in larger bodies of water as opposed to smaller ones. In this survey, the surveyors attach a multi-beam echo sounder to a boat. This sounder sends out a wide variety of beams across a large area of the floor of the water. How this works is that as the beams bounce back from the floor of the water, us surveyors collect and process the incoming data. We can view this data in real time during the survey. So the results come in pretty fast, which means the whole process speeds up since there is no lag time to find anything out.
So this is essentially the same process as the multi-beam survey, but instead of sending out multiple beams it is just the one beam. Which means it is generally used for smaller bodies of water. During this bathymetric survey method, surveyors measure the water depth that is directly under the boat.
The Ecomapper is a self-driving underwater vehicle that collects crucial and accurate bathymetric data. So precise that it does it down to one-foot contours that are very difficult to reach with boats. How it does this is to utilize a side-scan sonar and a Doppler velocity log.
Surveyors commonly use a sub-bottom profiler to view the layers of sediment and rocks under the water body floor. How it works is that a transducer sends a sound wave to the water body floor and collects data. This sound wave can even penetrate the floor of the water. In the end, the sound waves send back data and in return can map out the layers beneath the water body flow.
An Acoustic Doppler Current Profiler, or an ADCP, measures streamflow. How they work is that they measure the water velocity by transmitting sound waves which then reflect off sediment and other materials in the water. The collection of data at the end can be used for detailed bathymetric mapping.
