During the night, where North Sea and River Schelde come together, where the estuary is 6 km wide, a lot of seagoing ships travel to there destination in the night (most of them to or from the harbour of Antwerp in Belgium). <a href="https://commons.wikimedia.org/wiki/File:Westduin_strand.jpg" rel="nofollow"><img alt="Westduin strand" src="https://upload.wikimedia.org/wikipedia/commons/thumb/8/89/Westduin_strand.jpg/512px-Westduin_strand.jpg"></a> The ship engines create a deep humming sound around the water. Sometimes the deep rumble drown down the sound of the waves of the low-tide sea with there 15 cm high waves. Some ships pass close on 400m. Do you smell the combusted fuel oil? Some are 6 km away. The recording ends exactly at the moment of low tide. The surf is than just 150 meters from the microphones, and remarkable quiet (low waves, no wind at all). When you take your time to listen you'll hear the resistance against motion in this ambience of slow seagoing ships and tide. I would like record and upload this for 6 hours, the time a full tide takes, but Bram, the leader of the gang from freesound, will kill me than. The Northeren 0-1 bft breeze is coming from land behind me. Please note that only very good speakers / headphones with a very extended bass response will do this recording real justice. Location: Westduin beach, Dishoek (close to city of Vlissingen), Holland (The Netherlands). Gear: Primo EM 172 in AB40 setting in Rode Blimp &gt; Sony PCM D50. This recording is not equalized.
