This book is a printed edition of the Special Issue "Water Optics and Water Colour Remote Sensing" that was published in Remote Sensing
Water is irreplaceable natural resources on the planet for people to survival and develop. Declining water quality has become a global issue of significant concern as anthropogenic activities expand and climate change threatens to cause major alterations to the hydrological cycle. Thus, monitoring the physical, chemical, and biological status of rivers, reservoirs, lakes, coastal waters, and oceans is immensely important. Remote sensing has the potential to provide an invaluable complementary source of data at local to global scales. This book-Water Optics and Water Colour Remote Sensing-provides an overview of the current state of the science on water optical properties and water colour rem...
This book constitutes the proceedings of the 25th Italian Conference on Geomatics for Green and Digital Transition, ASITA 2022, held in Genova, Italy, in June 2022. The 33 full papers included in this book were carefully reviewed and selected from 60 submissions. They were organized in topical sections as follows: Positioning, Navigation and Operational Geodesy; Data exploitation: services and tools; Geo(big)data, GeoAnalytics, AI and Decision Support; Agriculture and Forestry; Cultural Heritage and Landscape Analysis; Environmental Monitoring and Analysis; and Sustainable Development and Climate Change.
Marine ecosystems are changing at an unprecedented rate. In addition to the direct effects of e.g. warming surface temperatures, the environmental changes also cause shifts in plankton communities. Plankton makes up the base of the marine food web and plays a pivotal role in global biogeochemical cycles. Any shifts in the plankton community composition could have drastic consequences for marine ecosystem functioning. This Research Topic focuses on causes, effects and consequences of such shifts in the plankton community structure.
Lakes are inestimable renewable natural resources that are under significant pressure by human activities. Monitoring lakes regularly is necessary to understand their dynamics and the drivers of these dynamics to support effective management. Remote sensing by satellite sensors offers a significant opportunity to increase the spatiotemporal coverage of environmental monitoring programs for inland waters. Lake color is a water quality attribute that can be remotely sensed and is independent of the sensor specifications and water type. In this study we used the Multispectral Imager (MSI) on two Sentinel-2 satellites to determine the color of water of 170 Italian lakes during two periods in 201...
This study focuses on the use of remote sensing to generate coastal erosion risk maps for Pianosa Island (Tuscany) and Piscinas dune system (Sardinia). The method made use of both ancillary and satellite data (Sentinel-2), in addition to SAR images (COSMO SkyMed and Sentinel-1B). TOA radiance products were atmospherically corrected and processed using Sen2Coral and BOMBER in order to map different marine substrates and bathymetry. The coastal erosion risk maps have been generated based on these output and the results confirm that the coasts of these sites don't have coastal erosion problems.
