Abstract: Climate change and coastal heritage in Puerto Rico: coastal erosion and extreme atmospheric events
Islands and coastal zones preserve the cultural heritage of maritime traditions and livelihoods. The expected environmental impacts linked to climate change present a severe threat to their preservation, placing heritage at risk of being completely lost, possibly in an instant. Coastal cultural heritage in Puerto Rico has been the focus of research for the last two years, starting with a risk assessment, and continuing with plans for monitoring, documentation and possible intervention. However, the severity of climate change and the intensity of recent extreme events highlights the urgency of these tasks and outpace the research to document and preserve the contexts that have survived until now. This presentation provides an update on the work undertaken on Puerto Rican coastal heritage, contextualizing our progress within the effects that Hurricane Maria had on the coastal geomorphology and on some of the known and threatened coastal heritage sites.
Abstract: Observing the small-scale variability of the sea
Physical variability in the ocean on short spatial and temporal scales is fundamental to a diverse set of globally important processes, including ocean/atmosphere coupling, biogeochemical exchange, ocean pollution, and climate change. The reliable observation of these scales of oceanic variability is technically challenging but crucial for the validation of numerical forecasts and to enable future discoveries. In this talk, I’ll present three vignettes that describe our recent efforts to develop and apply ocean sensing technology to problems of air/sea interaction, internal wave-driven variability in biogeochemical processes, and coastal water quality. In the Indian Ocean, a combination of autonomous platforms and shipboard observations demonstrate the influence of spatial heterogeneity in the unusually shallow mixed layer on monsoon variability. Closer to home, SIO-developed technology demonstrates the influence of the internal tide on biogeochemical cycling and the coastal ecosystem in San Diego waters. Finally, applying new technology to problems of coastal ocean monitoring, particularly regarding wastewater discharge from sewage treatment and desalinization plants, will be discussed.
