Forecasting the Shore: Walter Munk's Wave Science That Shaped D-Day
From orbit to ocean floor, the science of waves has shaped history in ways most never consider. Walter Munk and Harold Sverdrup gave us "significant wave height," a validated, empirical tool that still underpins ocean intelligence today. Their work forecasting surf for the D-Day landings is a masterclass in applied science. Understanding drives protection.

Wave Height Estimates from MEMS Sensors: Impact of Data Processing Methods
Wave height estimates from MEMS sensors are only as reliable as the processing choices behind them. A 31-day record from one operational buoy reveals that method selection introduces a mean spread of 0.023 meters, with a 95th percentile relative spread of 6.42%. These numbers isolate processing variability, not full uncertainty. Time-domain stabilization drove larger differences than spectral estimator swaps. That distinction matters for operational monitoring, where consistency is the real currency.
Long-Lasting Baltic Storm Surge Highlights Coastal Vulnerability in 2009
In October 2009, the Wimar storm surge pinned the southern Baltic coast under an unusually prolonged NE wind event, driving water levels 2.5 m above mean sea level. The result was extensive inundation and a mean dune retreat of 3.3 m, with maximum erosion reaching 8 m. This study shows that beaches sitting lower than the run-up level offered little defence. The lesson is clear: duration matters as much as intensity.
Optimizing Wave Models with Genetic Algorithms for Typhoon Forecasting
Typhoon-driven waves resist easy prediction, and the SWAN model knows it. Under extreme conditions, its default parameters overestimate reality, a gap this study confronts directly. By applying a genetic algorithm to optimize key physical settings, the researchers achieved measurable gains in significant wave height accuracy for two South China Sea events, though mean wave period lagged, a limitation tied to spectral complexity. The balanced parameter scheme outperformed alternatives on the engineering-critical metric.
