 Abstract: Tropical coastal regions move landward and oceanward during rain and dry seasons due to land hydrological loads, as observed with seasonal movements of GNSS stations. Here we use GNSS and GRACE data and present a few exceptional cases, i.e., GNSS stations move oceanward during rain seasons. In Northern Australia. stations along the coast of the Gulf of Carpentaria move oceanward during the rain seasons with significant phase shift between the peak subsidence and peak oceanward movement. We explain this as the interaction of two significant seasonally changing masses in ocean and land. Such seasonal mass changes within GOC have been largely overlooked because of insufficient spatial resolution of satellite gravimetry. This study presents a model case for interpreting complicated seasonal surface deformation caused by significant seasonal load changes on land and ocean, often found in coastal areas of half-closed oceans in the world.
