“…At the same time, they also generate an important number of other less evident, but with a high ecological value, ecosystem services such as flood control, the prevention of seawater intrusion, groundwater recharge, shoreline stabilization, storm protection, the retention and export of sediment and nutrients, the mitigation of climate change, water purification, or acting as reservoirs of genetic or species biodiversity. This translates into a remarkable socioeconomic role by providing a significative set of societal goods and benefits (Barbier et al, 1997;Ramsar Convention and Secretariat, 2006;Anthony et al, 2009;Pérez-Ruzafa et al, 2011b, 2019bBasset et al, 2013;Barbier, 2015;Newton et al, 2018;Velasco et al, 2018).…”

Coastal lagoons are considered among the marine habitats with the highest biological productivity, and support a great variety of human activities and pressures that make them especially vulnerable to trophic imbalances. While dystrophic crises are common in many lagoons, others like the Mar Menor show homeostatic mechanisms, high resilience, and clear waters. This paper analyses the water column descriptors dynamic during the last 22 years in this coastal lagoon, in the context of a eutrophication process produced by an increase in nutrient inputs, mainly derived from agriculture. Despite water column nitrate concentration increased by one order of magnitude, the lagoon maintained homeostatic regulation for two decades, keeping the water transparency and relatively low levels of nutrients and chlorophyll a (Prebreak phase), followed by a sudden change of state in 2016 with an abrupt increase in average nutrients and chlorophyll a concentration and loss of water transparency (Break phase), and a relatively rapid recovery after the reduction of nutrient discharges (Recovery phase). The activation of the regulation mechanisms seems to manifest through an ammonium production in the water column, as a consequence of the activity in the trophic web. The low correlation between chlorophyll a and nutrients concentration, mainly at small spatio-temporal scales, is in disagreement with eutrophication traditional models, and suggests a rapid response of primary producers to nutrient inputs and a zooplankton control in the short-term, which in turn is controlled by the rest of the trophic web components. Homeostatic properties that in the Mar Menor lagoon have provided resistance to eutrophication are based on several mechanisms: channeling its production toward the benthic system (maintaining high biomasses of primary producers, filter feeders, and detritivores), a top-down control of the pelagic trophic web exerted by ichthyoplankton and jellyfish, and exporting surplus production outside

“…This effect is the reason why the Encañizada gola bottom is moving and changing [25,79]. The exchange between Mediterranean and lagoon waters can be affected because of changes in the inlet's geomorphology, and these changes can affect the biological productivity, the species richness, and the complexity of the lagoon communities [80][81][82], and, therefore, affecting the environmental and economic balance of this area. Precise knowledge of the spatio-temporal evolution of the opening of this golas is very useful to improve the results of the hydrodynamic models that are being implemented for the Mar Menor lagoon and its connection with the Mediterranean Sea.…”

The use of the new generation of remote sensors, such as echo sounders and Global Navigation Satellite System (GNSS) receivers with differential correction installed in a drone, allows the acquisition of high-precision data in areas of shallow water, as in the case of the channel of the Encañizadas in the Mar Menor lagoon. This high precision information is the first step to develop the methodology to monitor the bathymetry of the Mar Menor channels. The use of high spatial resolution satellite images is the solution for monitoring many hydrological changes and it is the basis of the three-dimensional (3D) numerical models used to study transport over time, environmental variability, and water ecosystem complexity.

“…An excessive contribution of nutrients in surface waters, especially nitrogen and phosphorus, gives rise to a rapid proliferation of aquatic vegetation, as a consequence of oxygen depletion on the surface, which favors the appearance of eutrophication processes [4]. The Mar Menor (Region of Murcia, southeast of Spain) has been in the news in recent years due to the eutrophication, which refers to the processes of the ecosystem originated by the enrichment of nutrients of the water, especially nitrogen and/or phosphorus [5,6]. This situation, added to by the fact that most of the effluents from the wastewater treatment plants (WWTP) in this area are used for irrigation in agriculture, implies an increase in responsibility of the water industry to adopt a more sustainable management of urban water systems for this type of compound [7].…”

The deteriorating water environment demands new approaches and technologies to achieve sustainable and smart management of urban water systems. Wireless sensor networks represent a promising technology for water quality monitoring and management. The use of wireless sensor networks facilitates the improvement of current centralized systems and traditional manual methods, leading to decentralized smart water quality monitoring systems adaptable to the dynamic and heterogeneous water distribution infrastructure of cities. However, there is a need for a low-cost wireless sensor node solution on the market that enables a cost-effective deployment of this new generation of systems. This paper presents the integration to a wireless sensor network and a preliminary validation in a wastewater treatment plant scenario of a low-cost water quality monitoring device in the close-to-market stage. This device consists of a nitrate and nitrite analyzer based on a novel ion chromatography detection method. The analytical device is integrated using an Internet of Things software platform and tested under real conditions. By doing so, a decentralized smart water quality monitoring system that is conceived and developed for water quality monitoring and management is accomplished. In the presented scenario, such a system allows online near-real-time communication with several devices deployed in multiple water treatment plants and provides preventive and data analytics mechanisms to support decision making. The results obtained comparing laboratory and device measured data demonstrate the reliability of the system and the analytical method implemented in the device.
