ABSTRACT
P. oceanica is a species of seagrass indigenous to the shallow water seabeds in Mediterranean Sea. The large underwater meadows it forms span the shallower waters around the islands and are vital to the sustainability of its encompassing marine ecosystem. Recently, environmental impacts have resulted in an irreversible degradation of the species. Stronger evidence of degradation is needed to provide reason for changing policy on activities that are potential sources of environmental impact. By running a classification algorithm on aerial imagery containing visible P. oceanica, data points that circumscribe the species in polygons can be created. By projecting this data on the original images, information about the species' environmental presence is visualized. Accuracy of the data can be verified by collecting ground truthing data. When repeated over multiple years, a history of the environment and the species' coverage can be built, providing evidence of environmental trends.

Indian Ocean tsunami: The use of MERIS (MTCI) data to infer salt stress in coastal vegetation
MERIS (MEdium Resolution Imaging Spectrometer)The Indian Ocean tsunami of 26 December 2004 removed coastal vegetation and inundated large areas of near-coastal and low lying land with salt water. There were subsequent reports of early vegetation senescence as salt stress reduced the chlorophyll ...
Scaling up: linking field data and remote sensing with a hierarchical model
Spatial EcologyEcologists often seek to understand patterns and processes across multiple spatial and temporal scales ranging from centimeters to hundreds of meters and from seconds to years. Hierarchical statistical models offer a framework for sampling design and ...
Tsunami observations by coastal ocean radar
Satellite observations of the atmosphere, ocean and their interface in relation to climate, natural hazards and management of the coastal zoneWhen tsunami waves propagate across the open ocean, they are steered by the Coriolis effect and refraction due to gentle gradients in the bathymetry on scales longer than the wavelength. When the wave encounters steep gradients at the edges of ...
