Dredging operations are essential to protect coastlines, safe navigation and ensuring access to harbours. With threats of sea level rise, flooding and more extreme storms, the need for dredging operations will only increase and their sustainable implementation will be key. Clients are ever more aware of the need for a sustainable dredging operation and also …
All waterbodies are changing in the variable climate conditions. Monitoring of these changes over large areas is possible only by using remote sensing. However, remote sensing of lacustrine waterbodies is hampered by the nearby land as part of the signal measured above the waterbodies originates from the nearby land not from the water itself. This …
Microalgae blooms represent an increasingly present risk in coastal regions. They have in fact been favoured, in recent years, by the increasing anthropization of these areas and global warming throughout the world. Efflorescences, or blooms, lead to overconsumption of oxygen which can lead to attacks of anoxia, but they can also be toxic, or cause …
Background Following on from the 15, 20 and 25 “Years of Progress in Radar Altimetry” Symposia (respectively in 2006, 2012, and 2018), all deemed very successful milestones by the participants and the readership of the Proceedings, we have now reached the 30-year anniversary of precise altimetry. To mark this occasion the European Space Agency, in …
Background Environmental crime is growing at annual rates of 5% to 7% globally. Countering environmental crime is complex as it is often perpetrated by criminal organizations operating across borders. It also spans a broad range of activities, such as illegal waste management and shipment, illegal logging and trade in timber, illegal water abstraction, pollution, habitats …
Coastal Blue Carbon is the carbon captured and sequestered by photosynthetic organisms and ultimately stored in the biomass, soils and sediments within and beyond coastal vegetated ecosystems, such as salt marshes, seagrass beds and mangrove forests, for periods of time relevant to climate change mitigation. These Blue Carbon Ecosystems (BCEs) may contribute to 50% of …
As a third project in the EO for Ocean Acidification pathway, the objectives of the current efforts are: (i) to advance the scientific state-of-the-art in Ocean Acidification and its impact on marine life and ecosystems; (ii) to develop the next generation of EO-based products by capitalizing on the synergistic opportunities offered by the increasing fleet …
Despite their global coverage and public availability, measurements of water quality parameters retrieved by remote sensing have not been used for local short-term forecasting of water quality yet. In fact, forecasting based on remote sensing water quality products with on-ground resolution from, say, 30 m (Sentinel-2 MSI, Landsat-8/9 OLI) to 300 m (Sentinel-3A/B OLCI) or …
In situ bio-optical datasets are essential for the assessment of the uncertainties of satellite ocean colour measurements and derived products. This is especially critical in coastal waters (between 200m and 5km distance from the coastline), where land adjacency effects, complex atmospheric aerosol mixtures, high loads of optically active components in particular high concentration of chromophoric …
Sustainable Development Goals (SDGs) are meant to assist countries to manage and monitor progress on the three key interconnected components of sustainable development: economic growth, social inclusion, and environmental sustainability. This must therefore be integrated into the national policies and processes. EO is potentially a great source of information for mapping and monitoring SDGs either …
