Coastal lagoons deliver a wide range of valuable ecosystem goods and services. These
ecosystems, that are often maintained by direct or indirect groundwater supplies, are …

Terrestrial groundwater discharging directly into the sea (“fresh submarine groundwater
discharge”, fresh SGD) is increasingly recognized as nutrient and pollutant pathway from …

Radium isotopes and radon are routinely used as tracers to quantify groundwater and
porewater fluxes into coastal and freshwater systems. However, uncertainties associated …

Abstract Submarine Groundwater Discharge (SGD) is recognized as a fundamental
hydrological process that supports many coastal biogeochemical cycles and social …

The specific ingrowth rates of different radium isotopes make them valuable tracers to
distinguish processes occurring at different temporal scales. Here we demonstrate the use of …

Evaluating the sources of nutrient inputs to coastal lagoons is required to understand the
functioning of these ecosystems and their vulnerability to eutrophication. Whereas terrestrial …

Tracer approaches to estimate both porewater exchange (the cycling of water between
surface water and sediments, with zero net water flux) and groundwater inflow (the net flow …

Groundwater discharge transports dissolved constituents to the ocean, affecting coastal
carbon budgets and water quality. However, the magnitude and mechanisms of …

Bioactive trace metals play a significant role as micronutrients in the ocean and therefore it is
important to evaluate their sources. Submarine groundwater discharge (SGD) has been …

Benthic fluxes of biogenic compounds play a major role in the biogeochemistry of shallow
aquatic environments. Quantifying these fluxes at the scale of a lagoon is a challenge …
