[email protected] The coastal zone, where fresh and saltwater meet, hosts some of the most dynamic, diverse and productive ecosystems on Earth. These ecosystems experience significant pressure from human activities, responding to direct and indirect human disturbance and to climatic-hydrologic variability. Hydrological land-ocean connectivity is an important driver of these ecosystems. It greatly affects coastal ecosystem processes such as nutrient cycling, algal and zooplankton community dynamics, ecosystem metabolism or food web dynamics. The critical role of surface water discharge from rivers to coastal ecosystems has been well documented. In the past decade or so, the hidden subsurface flow of coastal (intertidal and submarine) groundwater discharge and associated geochemical and hydrological processes have received an increasing amount of scientific attention.
