Real-time Underwater Photogrammetry: Assessing Challenges, Benefits, and Limitations for Underwater Navigation and Mapping with Optical Sensors.

Written by: Fickrie Muhammad Underwater robotics have greatly improved marine science and technology, making ocean exploration and offshore inspections much easier. These robots are essential for tasks like checking ship hulls and finding structural damage or simply ocean mapping. Autonomous underwater vehicles (AUVs) equipped with advanced sensors are key for mapping the ocean floor and…

Standard Hydrographic Echosounders might Underestimate Depths: Bathymetric Surveys in Shallow Muddy Environments

Written by: Poerbandono The mapping of seafloor topography has been largely relying on standard hydrographic echosounders. Sounds propagate effectively in seawater. Their natures are well recognized and become the basis of knowledge in the design of underwater surveys’ technology. With that, sonar devices (including echosounders) are hence developed and fortified with specific features for different…
