"WebAbout half of the waves in the open sea are less than 2 m high, and only 10-15% exceed 6 m. But the ocean can produce some extremely large waves. The largest wind wave reliably measured at sea occurred in the Pacific Ocean in 1935, and was measured by the navy tanker the USS Ramapo. Its crew measured a wave of 34 m or about 112 ft high!

WebSources of low-frequency ambient background noise are often not well-understood, but a good understanding is essential to avoid pitfalls during data analysis and interpretation. In … WebIn this study, I analyze a passive seismic data set from the North Sea with regard to ambient noise sources in the frequency range 1–10 Hz. As we shall see, we can find a multitude of explainable ambient noise sources, some of which are external, and some of which are related to the sensor and recording packages themselves.
