January 11th, 2013

Recording made on 9th January 2013, on the north-east side of Boscastle Harbour, at a decidedly precarious position somewhat down on the cliff slabs directly above the blow-hole low down on the inland side of the hulk of Penally Point. The blow-hole is actually an early stage of the breaking-through of a sea cave on the seaward side of the hulk of Penally Point, and waves hitting the end of the cave there cause shockwaves in the air and cause the violent ejection of often quite long jets of spray with impressive heavy whoomphs. Those jets of spray are generally roughly horizontal or very slightly inclined upwards, and you can hear the ejected water splashing down following many of the whoomphs. However, on one occasion just while I was setting the recorder up for this recording, there was an almighty whoomph, much more strongly 'earthquaky' than any of the others I heard, and the ensuing jet from the blow-hole shot up to even a bit higher than where I was - though fortunately spray didn't come this way, so I didn't have to retreat.

The blow-hole in operation at the foot of the cliff.
The recorder is an almost imperceptible whitish speck on the steep slope.

That looks precarious? -- Yes, it was, especially as many patches of the rock slabs there were wet and slippery. I had to use extreme care in getting down from the rough little track on the rocks to the recorder position - but at least it was worth it!

The tide was coming in during this recording, and from about halfway through this results in the blow-hole whoomphs and ejections becoming progressively smaller. Indeed, I thought that they had actually stopped altogether and that I'd want to cut off some of this recording - but it is clear from listening to it, that the blow-hole had just become much more subdued and not (at least then) actually non-operational.

This recording was made with a Sony PCM-M10 on a Hama mini-tripod, using the built-in microphones covered with a Rode Deadkitten. There was a very light breeze coming from behind / left of the recorder, but not enough to notice at all in the recording.

Higher quality version of this recording available
The recordings that I upload to Freesound are of standard CD quality (44.1KHz, 16-bit). As from my recordings made on 9th January 2013, all my recordings are additionally available in 48KHz 24-bit, FLAC format. If interested, please see my Broad Horizon Natural Soundscapes page for details.
http://www.broad-horizon-nature.co.uk/arrow-long-right.gif Please note that all recordings from 7th January to 2nd Feb 2013, inclusive (i.e. including this one) did not receive any correction for high-frequency attenuation caused by the new Rode Dead Kitten windshield. Subsequently I was able to work out a graphic EQ profile to apply to all recordings that used that windshield, and have applied it retrospectively - but I have no plans to go through the hassle of re-uploading here the recordings that originally missed out on that correction. Therefore, copies of recordings made in that period, including this one, which I supply on CDs or as licensed copies for commercial use, will have better sound quality and will sound clearer, more 'present', and with more precision of detail than what you hear from here.

Please note that only very good speakers / headphones with a very extended bass response will do this recording real justice. Also, it may sound unpleasantly boomy on speakers that have any sort of boominess (like my computer speakers!). Please also note that the volume level of this recording has been carefully adjusted for listening purposes, and ALL my recordings so far are meant to be listened to with a volume setting that would give a realistic level for playback of CLASSICAL music (a large but not exceptional symphony orchestra). If you have the right volume setting, you should not need to change that setting from one recording of mine to another.

(Later note: This recording - with better sound than here - is on one of my commercial CDs, and can be found in my e-Store.)

**Please remember to give this recording a rating! http://www.broad-horizon-nature.co.uk/me-icon_wink.gif **
