CASPO Seminar: Greg Sinnett

11/20/2019 - 3:30pm
Nierenberg Hall 101
Event Description: 

Weekly CASPO Seminar: Join us in Nierenberg 101 every Wednesday at 3:30 pm to hear about the latest and greatest in Climate, Atmospheric Sciences, and Physical Oceanography


Dr. Greg Sinnett (UC Irvine) will present a talk titled "Distributed Temperature Sensing (DTS) application for nearshore internal wave and heat budget observations"


Recent results from a nearshore heat budget highlight large temperature variance driven by internal waves. As they propagate onshore, shoal, break and complete their run-up, internal wave characteristics transform at a variety of temporal and spatial scales. Dense instrumentation is often required to observe nearshore internal wave evolution (and other such processes evolving across a variety of scales). To this end, Distributed Temperature Sensing (DTS) is a relatively new approach to observing nearshore temperature evolution by continuously monitoring temperature along a fiber-optic cable. Although a number of recent studies have included DTS observations, and the method shows great promise, field implementation is difficult and noise makes resolving small temperature changes difficult.
Here, I will characterize internal wave run-up and effect on a recent nearshore heat budget. These results helped motivate a unique nearshore experiment to test a DTS system and optimize it for nearshore applications. I will show some preliminary results from this experiment leading to more robust DTS observations and an advanced capability to observe nearshore processes across a wide variety of scales. Finally, I will demonstrate the application of these results to a recent experiment on Dongsha Atoll (in the South China Sea) to observe internal wave interaction with a steep sloping coral atoll.
