Climate change research at UH Hilo: Monitoring the coasts for signs of erosion
Climate change is affecting more than just plants and animals—it is changing coasts and sea levels. Researchers at the University of Hawaiʻi at Hilo are monitoring these changes and the impact on local communities by gathering data that will help officials make sound predictions about, and decisions for, the future.
Rose Hart, a first-year graduate student in the Tropical Conservation Biology and Environmental Science program at UH Hilo, has teamed up with faculty member Ryan Perroy, an assistant professor of geography and environmental science at UH Hilo, to begin monitoring shorelines using an exciting and innovative technique.
The researchers are using small unmanned aerial vehicles to capture images of coastal areas across hundreds of acres. The images are used to create 3D data sets to observe past and present changes. A variety of coastal environments are being used for the study including sea cliffs (honoliʻi), low-lying and subsiding coastal lava fields (kapoho) and calcareous beaches (hapuna).
The project has a number of aspects and goals—one is to determine from a historical point of view how these coasts and regions have changed over time to present day. Another aspect is more short term, meaning that data collection occurs every couple of months to every few weeks to see how the coasts are currently changing.
The overall goal is to try to make accurate predictions on how the rise in sea level will affect the coast and what that entails for communities and the county in regard to planning. For example, setback regulations from the coastline may need to be adjusted. How the community will respond to the rising sea level is an important factor to consider especially in the long-term sense things will be dramatically different in the next 50 to 100 years.
