Miya is a master’s student in Physical Oceanography at Moss Landing Marine Labs, through California State University – Monterey Bay. She is a fellow with NOAA’s Center for Coastal and Marine Ecosystems, a Cooperative Science Center to provide a better understanding of issues confronting coastal and marine communities. Miya’s research is focused on understanding geomorphologic change and the associated hydrodynamic drivers and feedbacks that occur in the coastal zone. Her research utilizes a dual camera Argus station that allows for temporal monitoring of shoreline and sandbar in the northern Monterey Bay of Central California.
Beach morphology in the northern Monterey Bay responds to interannual, seasonal, and storm-scale variations in wave climate. However, the current understanding of morphologic change is based on biannual survey data, obscuring the effects of winter storms. Miya utilized nearly two years of continuous video observations collected every half-hour during daylight hours to build a time series of beach and nearshore morphology at Sunset State Beach.
Observations showed that most shoreline erosion occurs following the first large wave event of the winter season, though further erosion or subsequent recovery occurs according to wave characteristics during the rest of the winter. Miya’s work reveals higher coastal variability than previously observed in the northern Monterey Bay and offers insight into the impact of wave forcing and shoreline-sandbar interactions on shoreline change. By parsing apart the processes driving coastal change, we can improve forecasts and inform coastal resilience efforts by providing information to decision makers faster than previously possible with traditional survey methods.
