Large amounts of pollutants and natural disasters have been released into coastal and marine waters, wreaking havoc on the ecosystem and ecology. Pollution and habitat loss caused by humans have had and continue to have a significant impact on worldwide coastal and estuarine ecosystems. More than 80% of all marine pollution originates on land, with the majority of it coming from industrial, agricultural, and urban sources. Coastal and marine pollution is caused by human activities such as offshore oil and gas extraction and maritime oil transportation. Many of the world's estuaries and coastal zones are experiencing eutrophication, hypoxia, and other negative consequences as a result of anthropogenic activities. As a result, it's vital to avoid and regulate coastal and marine pollution, as well as build improved monitoring protocols and systems to aid in the understanding of spatial and temporal changes in coastal water quality. Recent technological advancements in coastal and marine seawater quality monitoring, such as real-time data collecting via data buoys, large-scale remote sensing intervention, automated data collection, and so on, are critical for comprehending real-time data and its influence on the environment.
It is critical to develop methods for processing long-term ecological monitoring data from coastal and marine areas in order to assess eutrophication and other environmental issues such as harmful algal blooms (HABs), heavy metal pollution, bioaccumulation, and the measurement of physicochemical variables and biological indicators in the coastal environment. These surveillance programmes create enormous databases, which are quite valuable for estimating the ecosystem's influence. To extract useful information, multivariate statistical analysis, neural networks, machine learning, modelling (GIS, CORMIX, MIKE, and MATLAB, among others), spatially weighted linear regression analysis, and other indices are used.
To address scientific need for massive dataset analysis and interpretation, recent technological advancements in methodology for analysing environmental variables must be enhanced. Physiochemical, plankton, nutrients, metal toxicity, benthos, microorganisms, and sediment quality are all examples of environmental quality metrics. These variables are crucial for assessing the environmental quality and ecology of the coastal and marine environments. Factor analysis, cluster analysis, discriminant analysis, self-organizing maps, artificial neural networks, canonical correspondence analysis, redundancy analysis, and numerous biotic indicators must all be used to analyse the enormous dataset. These techniques are used to determine the geographical and temporal variation of environmental parameters in coastal and marine waters, as well as the processes that cause it. The most recent technological advancements identify various patterns in datasets and deliver useful underlying data.
The purpose of this Research Topic is to investigate newly developed engineering modeling solutions, newly developed statistical tools, or a combination of methods or biotic indices in the coastal and marine sector, with a focus on terrestrial and sea interactions, in order to solve environmental and ecological problems through statistical analysis or modeling intervention.
