Short summary
Short summary
We employed a gradient-based algorithm to identify the position and intensity of the fronts in a coastal sea using sea surface temperature data, thereby quantifying their variations. Our study provides a comprehensive analysis of these fronts, elucidating their seasonal variability, intra-tidal dynamics, and the influence of winds on the fronts. By capturing the temporal and spatial dynamics of these fronts, our understanding of the complex oceanographic processes within this region is enhanced.

Short summary
This study reveals how seasonal changes shape the movement of nitrogen between the sediments and the overlying water in a semi-enclosed inland sea. By combining long-term observations with a purpose-built vertical model, we identify the key environmental drivers that control when and how sediments release nitrogen back to the water. These insights fill an important gap in understanding coastal nutrient dynamics and provide essential guidance for managing risks such as coastal eutrophication.

Short summary
Using a numerical model, we revealed that a large proportion of nutrients in a semi-enclosed sea (Seto Inland Sea, Japan) comes from the Pacific Ocean and supports about half of the phytoplankton growth in the sea. Such results imply that the human-made management of nutrient load from land needs to consider the presence of oceanic nutrients, which act as a background concentration and are not controlled by human activities.

Short summary
Earth system (climate) model is an important instrument for projecting the global water cycle and climate change, in which tides are commonly excluded due to the much small timescales compared to the climate. However, we found that tides significantly impact the river water transport pathways, transport timescales, and concentrations in shelf seas. Thus, the tidal effect should be carefully considered in earth system models to accurately project the global water and biogeochemical cycle.

Short summary
A bottom cold water mass (BCWM) is a widespread physical oceanographic phenomenon among coastal seas. Observations reveal a prominent interannual variation in a BCWM in the Seto Inland Sea during 1994–2015. We found that air–sea heat flux change during the warming season plays an important role in its interannual variation. Comparison with other BCWMs indicates that the size is a key factor for their difference. The findings help understand the response of BCWMs to sea surface forcing change.

Short summary
Submarine groundwater discharge (SGD), a common coastal hydrological process that involves submarine inflow of groundwater into the sea, is associated with a large nutrient load. To clarify the distribution of SGD-derived nutrients after release at the bottom of the sea and their contribution to phytoplankton growth in the marine ecosystem, we modeled the SGD process in Toyama Bay using a specialized computer code that can distinguish SGD-derived nutrients from nutrients from other sources.
