In this article, we describe the use of diagnostic timescales as simple tools for illuminating
how aquatic ecosystems work, with a focus on coastal systems such as estuaries, lagoons …

Within the framework of tidally flushed, semi-enclosed basins with negligible freshwater
inflow, and under steady periodic flow conditions, three frequently used local transport time …

Estuarine time scales including the turnover, particle e‐folding time, the age (calculated with
a passive tracer), and residence time (calculated with Lagrangian particles) were computed …

Using the concepts of the Constituent-oriented Age and Residence time Theory (CART), we
compute timescales related to the water renewal in the Scheldt Estuary (The …

Transport time scales are common metrics of the strength of transport processes. Water age
is the time elapsed since water from a specific source has entered a study area. An …

Global climate change has resulted in a gradual sea level rise. Sea level rise can cause
saline water to migrate upstream in estuaries and rivers, thereby threatening freshwater …

Phytoplankton distribution in macrotidal estuaries varies strongly due to highly dynamic
conditions, contributing to the complexity of aquatic environments and marine ecosystems …

Light is essential for phytoplankton photosynthesis and many other biogeochemical
processes in the aquatic system. However, light regimes vary greatly in the estuaries and …

Qatar's rapid industrialization, notably in its capital city Doha, has spurred a surge in land
reclamation projects, leading to a constriction of the entrance to Doha Bay. By reducing and …

Phytoplankton frequently blooms in estuaries and coastal seas. Numerous dynamic
processes affect these regions, generating complex hydrodynamics that induce intense …
