Satellite Derived Bathymetry (SDB) and Its Potential Role in Determining Maritime Boundaries

Featured image: Copernicus Data Space, Sentinel-2 Imagery. Written by: Eka Djunarsjah Satellite Derived Bathymetry (SDB) is a method for estimating shallow water depths using optical satellite imagery. Unlike conventional bathymetric surveys that rely on ships with echo sounders (such as Single Beam or Multibeam Echo Sounders) or airborne LiDAR, SDB leverages the ability of sunlight…

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…

Hydro 2024: See you above and below, Rostock Warnemünde, Germany

Written by: Fickrie Muhammad Hydro 2024, held in Rostock Warnemünde, highlighted emerging trends shaping the future of hydrography. A key focus was the generation of high-resolution seabed data by positioning sensors closer to the ocean floor. Advancements in marine robotics—whether above water, on the surface, or underwater—dominate current developments in the field. The conference also…
