Dr. Falk Feddersen: Coronado Water Contamination, Pt 1. - Ep. 132
For BUD/S, SWCC, and Marine Reconnaissance students in Coronado, water quality issues are a constant concern and a major occupational hazard. Dr. Feddersen is one of the leading experts on what’s in Coronado's water, how it gets there, and what it does. Falk Feddersen received his Ph.D. from Scripps Institution of Oceanography (SIO) in 1999, followed by a position as a postdoctoral scholar for two years at Woods Hole Oceanographic Institution. Dr. Feddersen studies various aspects of coastal and nearshore physical oceanography that span waves, currents, turbulence, and biological processes. His research includes instrument development, observations, theory, and modeling. His extensive field work experience includes projects in La Jolla, Huntington Beach, Point. Sal, the Monterey Peninsula, Surf Ranch, Imperial Beach in California, Duck and New River Inlet in North Carolina, and the Virgin Islands. These projects have resulted in new insights into how nearshore processes unfold, including rip currents, internal waves, and wind effects on wave overturning. Many of these findings are vital for understanding how pollution moves in the coastal ocean. His work has been supported by NSF, ONR, NOAA, other agencies, and private foundations. Dr. Feddersen has developed disciplinary and interdisciplinary coastal oceanography courses at SIO at the graduate and undergraduate levels. ------------------------ This is the first part of a two-part series on the water contamination in Coronado. In this episode, we’re talking about how the contamination gets into the water, what’s in it, and how scientists model how it spreads and how severe it is on a given day, sort of like a weather forecast. In a few days, we’ll release part two, focused on the medical impacts of the contaminated water. In other words, we’ll be discussing what happens to your body when you have to splash around in Tijuana poop water. If you’re in Coronado and want to see how much sewage is in the water today, you can find Dr. Feddersen’s pathogen forecast model for Coronado and Imperial Beach at https://pfmweb.ucsd.edu/ Timestamps: 00:00:22 Introduction to Dr. Falk Fedderson 00:02:19 How much Sewage is in the Water in Coronado? 00:05:19 Viral Gastroenteritis and Norovirus 00:08:18 The Movement of Sewage in Our Oceans 00:12:02 Treatment of Sewage: Worse Over the Past Two Decades 00:17:33 Do New DNA Tests Overstate the Risk? 00:18:44 Are There Airborne Risks? 00:21:05 Improvement on the Horizon for Tijuana 00:24:41 Sewage Outflow Modeling 00:26:24 Online Modeling and Beach Advisories 00:28:40 How is the Sampling Actually Done? 00:30:28 Outro Send us a message
