abstract = "{The northern shallow seas of Australia exhibit significant interannual
mass variations driven by complex oceanographic and hydrological
processes. While large-scale oceanographic and hydrological
mechanisms in this region are well studied, the specific
contributions of individual processes to these variations
require further quantification. To this end, we employed
satellite gravity, satellite altimetry, and Global Navigation
Satellite System (GNSS) to investigate sea level changes and
their loading effects from 2003 to 2022. Our results reveal that
strong colored noise significantly affects GRACE-derived mass
trend estimates, emphasizing the need for spatially varying
noise models. We also find that sea levels in the northwestern
sea and the Gulf of Carpentaria (GOC) have risen steadily,
primarily due to the increase in ocean mass (0.50
{\ensuremath{\pm}} 0.20 and 0.46 {\ensuremath{\pm}} 0.24 cm/a,
respectively). Monsoons and associated rainfall drive the
increase in water mass in GOC, while ocean currents outside the
GOC also significantly influence the mass changes. A net mass
outflow is observed during the four summer months (261.5
{\ensuremath{\pm}} 105.4 Gt), while the remainder of the year
shows a net inflow (333.6 {\ensuremath{\pm}} 51.8 Gt). In
addition, vertical displacements from nine GNSS stations around
the GOC were used to independently retrieve daily mass
variations from 2017 to 2021. The GNSS-derived mass variations
exhibit consistency with GRACE in both seasonal and interannual
variability and offer enhanced temporal resolution.}",
