Sample 2D Bathymetric Maps
Bathymetric maps are unique maps that reveal the topography of the ocean floor, providing insights into the ocean’s depths that were previously unknown. These maps are created using a combination of technologies that measure the depth and shape of the seafloor, allowing us to understand its complex features and the fascinating geological processes that shape our oceans. Here are some of the features of bathymetric maps that make them such a valuable tool for marine exploration and research.
Contours: One of the most distinctive features of bathymetric maps is their contour lines. These lines connect points of equal depth, revealing the shape and structure of the seafloor. The contour lines can be closely spaced in areas of steep topography, such as underwater canyons or ridges, or widely spaced in areas of gentle slopes. By examining these contours, scientists can identify key features such as underwater mountains, valleys, and trenches.
Hypsometric Tinting: Hypsometric tinting is another feature of bathymetric maps that provides valuable information about the seafloor. This technique uses different colors to indicate different depths, allowing viewers to easily distinguish between shallow and deep areas. Hypsometric tinting can also be used to highlight areas of interest, such as underwater volcanoes or seamounts.
Shaded Relief: Shaded relief is a technique that creates a three-dimensional representation of the seafloor. By combining contour lines with shading, bathymetric maps can provide a more detailed and realistic view of the underwater environment. Shaded relief can help researchers visualize underwater features such as cliffs, valleys, and canyons, and can also reveal the behavior of ocean currents and tides.
Bathymetric Profile: A bathymetric profile is a cross-sectional view of the seafloor, showing the depth of the water at different points along a specific line. These profiles can provide valuable information about the topography of the seafloor, including the height and shape of underwater mountains and ridges, as well as the depth and width of underwater canyons.
Ocean Floor Textures: Another feature of bathymetric maps is their ability to reveal the texture of the ocean floor. By using different shading and coloring techniques, bathymetric maps can highlight areas of the seafloor that are composed of different materials, such as sand, mud, or rock. This information can help scientists understand the composition and structure of the ocean floor, which in turn can provide insights into the geological processes that shape our planet.
Data Points: Bathymetric maps are also characterized by the data points used to create them. These data points come from a variety of sources, including satellites, ships, and autonomous underwater vehicles (AUVs). Each data point represents a measurement of the depth and shape of the seafloor at a specific location, and when combined, these data points create a detailed and accurate representation of the ocean floor.

How 3D Bathymetric Maps are Made
There are several techniques used to create bathymetric maps, and the process can vary depending on the scale and complexity of the map. However, the basic steps involved in making a bathymetric map are as follows:
- Create a base map. The first step in making a bathymetric map is to create a base map of the area. This can be done using imagery from a standard two-dimensional map, aerial photographs, satellite images, or WhiteClouds can do it for you.
- Determine the design style of the map. There are over 40 styles to choose from. Popular ones include satellite, terrain, topography, raised relief, and satellite hybrid.
- Add any special design features not included in the source map, such as special features, landmarks, legends, roads, cities, symbols, etc.
- Add elevation data. The next step is to add elevation data to the map. This can be done using a variety of techniques, such as contour lines, shading, or digital elevation models (DEMs).
- Print the Map Overlay. Latex vinyl materials are used for the map details and colors.
- Create the 3D physical map. Once the elevation data has been added to the map, a physical 3D structure is created that replicates the topography of the area. This can be done using 3D printed plastic or thermoformed molding/casting. Either approach is combined with the Vinyl overlay.
- Finish the map. This is where any excess materials are cutaway. Any special sealers, matte finishes, hardeners, or UV protection is applied. Wood, metal or plastic bases are built and border flocking may be applied.

What is a bathymetric map? A bathymetric map is a type of map that shows the underwater topography or depth of a body of water, such as an ocean, lake, or river. Bathymetric maps are created using specialized equipment, such as sonar and echo sounders, to measure the depth of the water at various points. The depth data is then used to create a 3D model of the underwater terrain, which is represented on the map through contours, shading, and color coding.
Bathymetric maps are commonly used in marine navigation, oceanography, and fisheries management. They can provide valuable information about the location of underwater features such as canyons, seamounts, and ridges, which can have important ecological and geological significance. Bathymetric maps can also be used to identify potential hazards for navigation, such as shoals or shipwrecks, and to plan the placement of underwater infrastructure, such as pipelines or cables.

What is on a bathymetric map? A bathymetric map displays the underwater topography or depth of a body of water, such as an ocean, lake, or river. The map uses a variety of visual cues, such as contours, shading, and color coding, to represent the depth of the water at different points.
The primary feature of a bathymetric map is the contour lines, which represent the depth of the water at specific intervals. These contour lines are similar to those found on a topographic map, which shows the elevation of the land. On a bathymetric map, the contour lines connect points of equal depth and show the shape of the seafloor.
In addition to contour lines, a bathymetric map may include shading or color coding to further represent the depth of the water. For example, deeper water may be shaded in darker colors, while shallow water may be shown in lighter colors.
Bathymetric maps may also include other features, such as labels for important underwater features, like canyons, ridges, or seamounts. They may also show locations of shipwrecks, navigational hazards, or underwater infrastructure like pipelines or cables.
How are bathymetric maps made? Bathymetric maps are made using specialized equipment, such as sonar and echo sounders, to measure the depth of the water and create a 3D model of the underwater terrain.
Sonar, which stands for Sound Navigation And Ranging, works by sending out sound waves that bounce off the seafloor and return to the sonar receiver. By measuring the time it takes for the sound waves to travel and return, sonar can calculate the depth of the water. Modern sonar equipment is highly advanced, using multibeam sonar systems to provide highly accurate depth measurements.
Echo sounders work in a similar way to sonar, but they are typically used for shallower waters. Echo sounders send out a sound pulse that travels to the seafloor and bounces back to the echo sounder. By measuring the time it takes for the sound pulse to travel and return, echo sounders can calculate the depth of the water.
Once the depth data has been collected, it is used to create a 3D model of the underwater terrain. This model is then used to create the bathymetric map, which shows the depth of the water using contour lines, shading, or color coding.
In addition to sonar and echo sounders, bathymetric maps can also be created using satellite altimetry, which measures the height of the sea surface to infer the depth of the water below.
How do scientists collect data for bathymetric maps? Scientists collect data for bathymetric maps using a variety of specialized equipment, such as sonar, echo sounders, and satellite altimetry.
Sonar and echo sounders are two of the most common tools used for collecting bathymetric data. These instruments work by sending out sound waves that travel through the water and bounce off the seafloor, allowing scientists to measure the depth of the water. Modern sonar systems use multiple beams of sound to provide highly accurate depth measurements.
Satellite altimetry is another method used to collect bathymetric data. This technique involves using satellites to measure the height of the sea surface, which can be used to infer the depth of the water below. Satellite altimetry is particularly useful for mapping large areas of the ocean, but it is less accurate than sonar or echo sounders.
In addition to these techniques, scientists may also use other instruments, such as submersibles or remotely operated vehicles (ROVs), to collect bathymetric data in specific areas or for targeted research projects.
Once the bathymetric data has been collected, it is processed and analyzed to create a 3D model of the underwater terrain. This model is then used to create the bathymetric map, which shows the depth of the water using contour lines, shading, or color coding.
How does an echo sounder create a bathymetric map? An echo sounder is a device used to create a bathymetric map by measuring the depth of the water using sound waves. The device sends out a sound pulse that travels to the seafloor and bounces back to the echo sounder. By measuring the time it takes for the sound pulse to travel and return, the echo sounder can calculate the depth of the water.
To create a bathymetric map using an echo sounder, scientists will typically use a vessel equipped with the device to survey a given area. The echo sounder sends out a continuous series of sound pulses as the vessel moves through the water, creating a swath of depth measurements along the survey line.
Once the depth data has been collected, it is processed and analyzed to create a 3D model of the underwater terrain. This model is then used to create the bathymetric map, which shows the depth of the water using contour lines, shading, or color coding.
Modern echo sounders use advanced technology to provide highly accurate depth measurements. For example, some devices use multiple sound beams that can cover a wider area and provide more detailed measurements of the seafloor. Others use sensors that can detect the composition of the seafloor, providing additional information about the underwater environment.

However, if you are interested in creating a bathymetric map as a personal project, there are several steps you can follow:
How are islands differentiated from seamounts on bathymetric maps? Islands and seamounts can be differentiated on bathymetric maps based on their height relative to the surrounding seafloor. Islands are typically elevated landforms that rise above the water surface, while seamounts are underwater mountains or hills that do not reach the surface.
On a bathymetric map, islands are typically depicted as elevated land areas with contours indicating the height of the land above sea level. In contrast, seamounts are shown as underwater mountains or hills with contours indicating their height above the surrounding seafloor.
In addition to their height, islands and seamounts can also be distinguished based on their location and geological origin. Islands are typically formed by volcanic activity or the movement of tectonic plates, while seamounts can also be formed by volcanic activity or may be remnants of ancient mountains that have sunk below the surface of the ocean.

History of Bathymetric Maps
Bathymetric maps have a fascinating history that spans centuries and involves some of the most innovative minds in science and technology.
The first attempts to map the ocean floor date back to the 17th century when scientists began using weighted lines to measure water depth. These early methods were crude and inaccurate, but they provided the foundation for later efforts to map the seafloor.
In the late 19th century, advancements in technology led to the development of more sophisticated methods for measuring water depth, including echo sounders and sonar. These new technologies allowed scientists to create more accurate maps of the ocean floor and led to a revolution in our understanding of the seafloor.
One of the pioneers of modern bathymetric mapping was a scientist named John Murray, who led the first deep-sea exploration expedition in 1872. Murray and his team used dredging and trawling techniques to collect samples of the ocean floor and create the first detailed maps of the seafloor. Their work was groundbreaking and set the stage for the development of modern bathymetric mapping.
In the early 20th century, a scientist named Marie Tharp began working with geologist Bruce Heezen to create the first comprehensive map of the Atlantic Ocean floor. Tharp used sonar data to create a detailed map of the mid-Atlantic ridge, a massive underwater mountain range that stretches for thousands of miles. Their work was a major breakthrough and led to a greater understanding of plate tectonics and the geology of the ocean floor.
In the decades that followed, advancements in technology continued to transform bathymetric mapping. In the 1950s, scientists began using multibeam sonar to create more detailed and accurate maps of the ocean floor. This technology allowed researchers to create 3D images of the seafloor and provided new insights into the geology and ecology of the ocean.
In recent years, advancements in satellite technology and remote sensing have led to even greater breakthroughs in bathymetric mapping. Satellite altimetry, for example, measures the height of the sea surface, which can be used to infer the shape of the seafloor. This technology has led to the creation of more accurate and detailed maps of the ocean floor, even in remote and inaccessible regions of the ocean.
The history of bathymetric mapping is a testament to the human drive to explore and understand the world around us. From the early attempts to measure water depth to the cutting-edge technologies used to map the seafloor today, bathymetric mapping has played a vital role in our understanding of the ocean and its place in the natural world. As we continue to explore the depths of the ocean, bathymetric maps will remain an essential tool for unlocking the mysteries of the deep and uncovering the secrets of the ocean floor.
