Ocean Remote Sensing with Synthetic Aperture Radar

The ocean covers approximately 71% of the Earth’s surface, 90% of the biosphere and contains 97% of Earth’s water. The Synthetic Aperture Radar (SAR) can image the ocean surface in all weather conditions and day or night. SAR remote sensing on ocean and coastal monitoring has become a research hotspot in geoscience and remote sensing. This book—Progress in SAR Oceanography—provides an update of the current state of the science on ocean remote sensing with SAR. Overall, the book presents a variety of marine applications, such as, oceanic surface and internal waves, wind, bathymetry, oil spill, coastline and intertidal zone classification, ship and other man-made objects’ detection, as well as remotely sensed data assimilation. The book is aimed at a wide audience, ranging from graduate students, university teachers and working scientists to policy makers and managers. Efforts have been made to highlight general principles as well as the state-of-the-art technologies in the field of SAR Oceanography

Spaceborne L-Band Synthetic Aperture Radar Data for Geoscientific Analyses in Coastal Land Applications: A Review

The coastal zone offers among the world’s most productive and valuable ecosystems and is experiencing increasing pressure from anthropogenic impacts: human settlements, agriculture, aquaculture, trade, industrial activities, oil and gas exploitation and tourism. Earth observation has great capability to deliver valuable data at the local, regional and global scales and can support the assessment and monitoring of land‐ and water‐related applications in coastal zones. Compared to optical satellites, cloud‐cover does not limit the timeliness of data acquisition with spaceborne Synthetic Aperture Radar (SAR) sensors, which have all‐weather, day and night capabilities. Hence, active radar systems demonstrate great potential for continuous mapping and monitoring of coastal regions, particularly in cloud‐prone tropical and sub‐tropical climates. The canopy penetration capability with long radar wavelength enables L‐band SAR data to be used for coastal terrestrial environments and has been widely applied and investigated for the following geoscientific topics: mapping and monitoring of flooded vegetation and inundated areas; the retrieval of aboveground biomass; and the estimation of soil moisture. Human activities, global population growth, urban sprawl and climate change‐induced impacts are leading to increased pressure on coastal ecosystems causing land degradation, deforestation and land use change. This review presents a comprehensive overview of existing research articles that apply spaceborne L‐band SAR data for geoscientific analyses that are relevant for coastal land applications

Urban Deformation Monitoring using Persistent Scatterer Interferometry and SAR tomography

This book focuses on remote sensing for urban deformation monitoring. In particular, it highlights how deformation monitoring in urban areas can be carried out using Persistent Scatterer Interferometry (PSI) and Synthetic Aperture Radar (SAR) Tomography (TomoSAR). Several contributions show the capabilities of Interferometric SAR (InSAR) and PSI techniques for urban deformation monitoring. Some of them show the advantages of TomoSAR in un-mixing multiple scatterers for urban mapping and monitoring. This book is dedicated to the technical and scientific community interested in urban applications. It is useful for choosing the appropriate technique and gaining an assessment of the expected performance. The book will also be useful to researchers, as it provides information on the state-of-the-art and new trends in this fiel

Predictive Modeling Of Sinkhole Hazards Using Synthetic Aperture Radar Interferometry (Insar) Subsidence Measurements And Local Geology

The mining of salt domes provides economically important resources through salt and brine production and storage of petroleum products as part of the U.S. Strategic Petroleum Reserve. In order to assess the risk to nearby communities for potential of salt dome collapse, it is important to understand the growth of the Bayou Corne sinkhole and the conditions surrounding the Napoleonville Salt Dome that may have exacerbated its formation. The Bayou Corne sinkhole in Assumption Parish, Louisiana has been expanding since it formed overnight on 2 August 2012. Growing from slightly over 2 acres to more than 30 acres today, the sinkhole has forced the evacuation of approximately 350 local residents and threatens transportation on the nearby Highway 70 hurricane evacuation route. The sinkhole was caused by solution mining of a brine well (Oxy-Geismar Well 3), expanding the subterranean storage cavity too close to the edge of the salt dome. This caused a sidewall collapse into the storage cavity and a rapidly growing sinkhole. The response to the Bayou Corne sinkhole collapse has involved 12 local/state agencies and five federal agencies. The State of Louisiana initiated a $12 million lawsuit against the proprietor of the well, Texas Brine, to recoup much of the State’s costs for response to the sinkhole collapse. The potential for future subsidence in the Bayou Corne area continues to pose a risk to residents. To mitigate this risk, it is important to understand and identify the risk of collapse of caverns on mined salt domes
