Over two-thirds of Earth's surface and eighty percent of all plate boundaries are under water. This forms a natural barrier for direct application of space geodesy to measure seafloor motion and deformation. However, many critical Earth processes and infrastructure are underwater and require geodetic monitoring, including the sources of the largest earthquakes and tsunamis, underwater volcanoes, submarine landslides, and hydrocarbon pumping. Owing to the complex environments, seafloor geodesy is challenging and often expensive compared with its land counterpart, yet the techniques used hold the keys to answering many important scientific and engineering questions. Recent years have seen dramatic advancements in seafloor geodesy, paired with increasingly ambitious observational efforts. We invite presentations of the latest developments in seafloor geodetic methods, utilizing techniques such as GNSS-Acoustic ranging, direct or indirect-path acoustic ranging, spar buoys, ocean bottom pressure, tilt, strain, gravimetry, bathymetry, as well as other instrumental and analysis methods, and scientific applications.
