Towards Cost-Effective Operational Monitoring Systems for Complex Waters: Analyzing Small-Scale Coastal Processes with Optical Transmissometry

21 pages, 13 figures, 1 table, data availability https://doi.org/10.1594/PANGAEA.863589The detection and prediction of changes in coastal ecosystems require a better understanding of the complex physical, chemical and biological interactions, which involves that observations should be performed continuously. For this reason, there is an increasing demand for small, simple and cost-effective in situ sensors to analyze complex coastal waters at a broad range of scales. In this context, this study seeks to explore the potential of beam attenuation spectra, c(λ), measured in situ with an advanced-technology optical transmissometer, for assessing temporal and spatial patterns in the complex estuarine waters of Alfacs Bay (NW Mediterranean) as a test site. In particular, the information contained in the spectral beam attenuation coefficient was assessed and linked with different biogeochemical variables. The attenuation at λ = 710 nm was used as a proxy for particle concentration, TSM, whereas a novel parameter was adopted as an optical indicator for chlorophyll a (Chla) concentration, based on the local maximum of c(λ) observed at the long-wavelength side of the red band Chl-a absorption peak. In addition, since coloured dissolved organic matter (CDOM) has an important influence on the beam attenuation spectral shape and complementary measurements of particle size distribution were available, the beam attenuation spectral slope was used to analyze the CDOM content. Results were successfully compared with optical and biogeochemical variables from laboratory analysis of collocated water samples, and statistically significant correlations were found between the attenuation proxies and the biogeochemical variables TSM, Chl-a and CDOM. This outcome depicted the potential of high-frequency beam attenuation measurements as a simple, continuous and cost-effective approach for rapid detection of changes and patterns in biogeochemical properties in complex coastal environmentsThis study was supported by the Spanish Ministry of Economy and Competitiveness (MESTRAL project, CTM2011-30489-C02-01) and by Total Foundation (PHYTOSCOPE project).

Proyecto de asentamiento ex-novo barrio de Intaca (Mozambique)

El objetivo general del presente proyecto es contribuir al uso racional del suelo con fines urbanos, disminuyendo los niveles de informalidad en la vivienda y contando con el esfuerzo propio y la ayuda mutua como bases para el desarrollo del proyecto, posibilitando un plan vital integrado a través de la satisfacción de las necesidades de asentamiento, residencia y producción. El objetivo específico consiste en desarrollar un proyecto de asentamiento ex-novo para 670 familias en un área de 72 ha ubicada en el barrio de Intaca, a 23 km del centro de la ciudad de Matola. El proyecto incluye la comprensión del microterritorio, el análisis de los problemas existentes y el planteamiento de una solución integrada que los resuelva, pasando por las fases de análisis de la elección del sitio, parcelación, urbanización, y edificación. Es fundamental contar tanto con la fuerza de los pobladores (última fase principalmente), como con la colaboración de instituciones locales desde el comienzo
