How many people can Loch Ness hold?

It's one of those "amazing" facts that is trotted out about Loch Ness. The fact that the volume of water in Loch Ness is equivalent to containing the entire population of the world. But by how much seems a matter of opinion.

This website suggests ten times the world's population. The Daily Mirror seems to say the same, but says "surface area" instead of volume. Bzzzzz! Meanwhile, looking further back, issue 235 of the Europe magazine from 1983 states it is three times the world population.

It is one of those factoids like the one that the Post Office Tower or Eiffel Tower could be submerged in the loch without trace. But when this population fact was first mentioned was a bit of a mystery to me, though I certainly recall it going back before the Internet. I checked most of the classic books, but couldn't find any mention of it. Where had it come from and indeed does it stack up?

Now the volume of water in Loch Ness is stated as 7.5 cubic kilometres in its Wikipedia entry. This translates to 7.4 billion cubic metres. What is the average volume of a human? Not so easy to figure out, but good old Google suggested that water displacement measurements of 521 people of varying ages gave 66.4 litres or 0.0664 cubic metres. That seemed to be about half what I thought for an adult, but we are including babies and kids in our experimental mega-plunge.

Divide the volume of the loch by this average human volume and you get about 111,445,783,130 people fitting into Loch Ness. Since the world's population is currently estimated at about 7.3 billion, then you'll get them all into Loch Ness not just 10 times over but more than 15 times over. It seems our factmeisters were right but also underestimating things.

But what about surface area as the Daily Mirror misquoted? The best known fact on this wise is that the Isle of Wight can hold the entire standing population of the world. Okay, what about Loch Ness with a surface area of 56 million square metres? If we assume five people squeezing up per square metre, then that's 280 million people, which is well off the mark.

But, again, who first concocted this fact? Was it the Loch Ness Investigation Bureau or some more obscure book or booklet? If anyone knows, leave a comment or send an email.

Grumpy Skepticism

The world is full of Nessie sceptics, they may be young or old, fat or thin, near or far from the loch, they may be intelligent or dumb. What they do have in common is a shared belief that Loch Ness harbours no large, exotic species of animal. It is, of course, their right to hold such an opinion. However, another thing they may not have in common is the way they express that opinion and that involves personality.

Take these words from retired Loch Ness researcher, Tony Harmsworth, as he gave a short, grumpy pre-review of Gareth Williams' book, "A Monstrous Commotion".

Anyone studying the subject seriously might find it useful, but his repeatedly going into depth about exaggerated sightings and reports which, for anyone who knows the subject, have no credibility whatsoever, was the most annoying aspect of it and I found that extremely tiresome. This was the very reason why I didn’t include all of these irrelevant sightings in my own book. However, now they are all referenced, perhaps we can let them die a natural death. 

It seems Gareth's mistake was making these eyewitness reports sound too "real". I began to suspect that if Tony didn't like the book, then, ipso facto, I would like it. Since I have started reading the book, that feeling has partially been confirmed. I will put up a proper review when I have finished (as I am sure Tony will).

Now Tony does not really involve himself in the search for any form of Nessie these days, his presence on such forums is minimal to say the least. Having written his book, "Loch Ness Understood", he perhaps feels that is all he has to say on the subject. I note that when Tony mentioned a book by another sceptic, Ronald Binns, called "The Loch Ness Mystery: Solved", he describes this as "rather prematurely titled". Presumably, Tony has now "put the world to rights" with his similarly (but still prematurely) titled book!

Tony suggests Adrian Shine would do a better book on the history of the Loch Ness Monster and its pursuers. I wouldn't care to give an opinion on that but I would certainly look forward to such a book (as I did with Tony's).  I think Adrian is now aged 67 years old and must be nearing retirement from his post at the Loch Ness Centre in Drumnadrochit. Maybe after this we will see such a book.

As best as I can ascertain, Tony now tends to be preoccupied with aiming verbal arrows at people who believe in one or more gods (presumably he regards them as another set of witnesses who have misidentified something ordinary for something extraordinary). However, back to his quote.

In typical bombastic fashion, he put us to rights by describing all claims to seeing a large animal in the loch as being "exaggerated", having "no credibility", "tiresome", "irrelevant" and we ought to "let them die a natural death". And this, he says, should be obvious to "anyone who knows the subject".

Let us look at how Tony handles one of these claimed sightings. I refer to the John McLean case and how Tony has decided that this was in fact just a bird; a cormorant to be more precise. His post in facebook can be found here.

The long neck fits in with cormorants. It is well known that people overestimate sizes over water. The body drawings are typical of boat wakes or groups of birds apart from the last drawing which is a bit of a mystery. Bearing in mind that only around a third of an aquatic animal's body appears above the surface when swimming, the size estimates would put this animal at around 50 to 60 feet or almost the size of the largest animal on the planet - a blue whale. We also know that long-necked animals have high metabolic rates so there would be insufficient food in the loch for a long-necked creature of any size. Oh how I wish I could have been looking over his shoulder so that I could have pointed out that he was actually seeing a ...... or a ...... or a ......, but my Tardis is currently not operational.

Now to dig a bit deeper into these words.

The long neck fits in with cormorants. 

Well, it doesn't actually, the sketch by McLean looks nothing like a cormorant. The lack of a long beak is a give away. The proportions are also wrong.

It is well known that people overestimate sizes over water.

But not by a factor of nearly seven. McLean suggested a length of up to 20ft (610cm) while a cormorant is about 90cm long. Moreover, overestimates are not so credible at a range of under twenty yards. This is a bit like someone claiming they saw an articulated lorry pass by, only for some "expert" to tell them they actually saw a mini car. I think the words "exaggerated" and "no credibility" just as equally apply to Tony's strained interpretation of what Mr. McLean saw.

The body drawings are typical of boat wakes or groups of birds apart from the last drawing which is a bit of a mystery.

Group of birds, but only one neck? Curiouser and curiouser. It goes without saying that Tony completely ignores any experience John McLean may have had as regards boats and birds. After all, he had claimed to have seen the monster, so he is immediately an unreliable witness. That is circular reasoning by any other name. As for the inflated hump, Tony hopes we will just ignore this minor "mystery".

Bearing in mind that only around a third of an aquatic animal's body appears above the surface when swimming, the size estimates would put this animal at around 50 to 60 feet or almost the size of the largest animal on the planet - a blue whale.

Loch Ness Monster fans have always held that the creature has notable powers of positive buoyancy. This is rejected by sceptics, hence the unwarranted use of this one third formula. Tony fails to note that McLean said he saw the creature from tail to head, so that blows his one third calculation clean out of the water.

As a side note, here is a YouTube clip of an animal with positive buoyancy that matches and perhaps even exceeds that of our favourite cryptid. Nature again provides a precedent to the confounding of the sceptics.



We also know that long-necked animals have high metabolic rates so there would be insufficient food in the loch for a long-necked creature of any size. 

Well, using proof by contradiction, it appears the long necked nothosauridae did not - Quad Erat Non Demonstrandum.

Oh how I wish I could have been looking over his shoulder so that I could have pointed out that he was actually seeing a ...... or a ...... or a ......, but my Tardis is currently not operational.

Ah, such arrogance! Besides, Tony, I am sure you would rather send off your Tardis to more interesting times .... such as White Hart Lane in the early 1960s.

If this is what "anyone who knows the subject" knows, I will continue to live in ignorance, thanks very much.

The Infrasonic Nessie

The rise of scepticism has brought with it a desire to find more natural explanations for eyewitness claims to large creatures in lochs and lakes around the world. We are familiar with the older theories regarding boat wakes, seiches, vegetable mats, birds and other forms of misinterpreted phenomena, but not much new has hoved over the sceptical horizon recently.

So, it was with some interest that I noted a comment left by Loch Ness researcher, Dick Raynor, on this blog a couple of years back:

I am just beginning a new avenue of amateur investigation involving infrasound and I am sure that Ted and Tim would have been years ahead of me had they still been with us, as both of them (and I also) had experiences consistent with its effects.

This work, if successful, will in no way claim or prove that there are no unknown large animals in Loch Ness, it will only add to the argument that their existence is not necessary to account for the wide variations in observations and data obtained so far. If I see and film a plesiosaur from one of my boat tours tomorrow I will happily admit "Yup, there are plesiosaurs there too."

You can find Dick's thoughts on this matter at his website. In summary, the theory draws on previous work by Vic Tandy which suggested that inaudible sound at around a frequency of 19Hz triggers various physiological effects such as fear, blurred vision, shivering and dizziness. The blurred vision is alleged to be due to the human eyeball resonating at this frequency. Tandy's own personal experience made him think a grey spirit was entering at his peripheral vision but vanished when he turned to look at it.

Dick Raynor thinks this is applicable to some aspects of the Loch Ness Monster phenomenon. The infrasound waves are theorised to be generated by the culvert pipes below the road which then affect human observers near them. These pipes are used to run hillside water off into the loch and the photo below is of one such culvert at Loch Ness which I took recently.

However, how exactly this is to be applied to the Loch Ness Monster is not made clear on his website. A look around for Dick's other comments does not elaborate much more on the neurophysiological mechanisms involved or the proposed alterations in perception. One comment here has him actually applying the infrasound mechanism to Bigfoot as well!

Adding to what Rangoon says, the same naturally occuring infrasound could produce the perception of bigfoot in addition to the "bad" feelings. Witness is unaware of cause but senses both effects and the brain then turns one of them into a cause.

However, one assumes culverts do not run past Bigfoot sites. On another forum, he says:

Could it be that Science has added a new category of 'answer' that relies on modern physics, including infrasound-generated psychological / perception disturbances ...

Could produce, could it be? Maybe, but then again, maybe not. Let's look at issues with this theory.

SEMI-SCIENCE

Now Dick said (albeit two years ago) that this was a work in progress and it is just as well he said that because what we have just now is not science but at best incomplete science. He has proposed a theory, albeit thin on the human perception side, but having more to say on the matter of the physics of resonating culverts.

The main problem is immediately obvious to those with experience of the scientific method. There is no evidence that this theory has been tested. It is over two years now since Dick outlined his theory on his website, but nothing more has been added. What do we need to see to progress this?

First, is there any evidence of infrasound emissions near the culverts? Has Dick gone to some culverts with measuring equipment in an attempt to measure the presence of sound waves in the proposed frequency range? If nothing has been detected, clearly the theory is already dead in the water.

Secondly, the intensity of any proposed waves also need to be measured. Herein lies a deficiency with the theory as it is not stated at what decibel level the proposed perception-altering changes kick in. Culverts may emit at 18Hz, but may be too weak to have any effect on humans.

Thirdly, a control test needs to be done at a site well away from culverts on the loch side. This is to establish whether any theoretical infrasound presence can be statistically linked to the culverts rather than another potential cause. If infrasound were to be detected nowhere near culverts, it is unlikely to have anything to do with them.

Have any of these tests been done? If not, it is incomplete science, it is semi-science. Many a theory has been proposed over the centuries of scientific enquiry, they may have been totally plausible and mathematical, but in many instances they turned out to be wrong due to an unwarranted assumption, loose handling of the data or a missing piece in the equations.

On the other hand, it is of course entirely possible all this has been done, it just has not been published yet. In that light, we await the possibility of unrevealed research for further critique.

PEER CRITICISM

The other aspect to all of this is whether the initial and original theory is as worthy of acceptance as it is made out? In that light, I took a step back from what is being proposed regarding the Loch Ness Monster and sought out the opinions of others on Vic Tandy's theory of infrasound and paranormal phenomena. It did not take long to find a dissenting opinion.

This objection can be found in a paper authored by Jason Braithwaite and Maurice Townsend in October 2006 entitled "Good Vibrations: The case for a specific effect of infrasound in instances of anomalous experience has yet to be empirically demonstrated" which is a long winded way of saying "we don't think anything has been proven here".

I see that Dr. Jason Braithwaite lectures in Cognitive Science and Brain Science at Birmingham University and his academic profile is here.  You can obtain their article here. His view in the paper is that the infrasound phenomenon has not been properly quantified, there is no baseline data and the neurological side is inadequately stated.

That does not mean that infrasound effects on human perception have been proven false, it just means they are not proven to an adequate level of scientific enquiry. 

CONCLUSION

There is no proof that infrasound can perceptually affect observers at Loch Ness or anywhere else. No measurements at this time confirming their presence at culverts are forthcoming and there is no mechanism adequately explaining how resonating pipes lead to people seeing plesiosaurs. Apart from these objections, it's a great theory. :)

We await further scientific revelations from Dick Raynor.

Jennifer Bruce's Monster and Sucking

Every time I see a picture of a gull, I think of the 1982 picture of the Loch Ness Monster by Jennifer Bruce. I wrote about this in 2013 and when I look at such a gull picture, I am less convinced by the sceptical interpretation that it is nothing more than a passing seagull. Let's just say that if that was a gull, it would be so deformed as to be incapable of flying in the first place!

I saw yet another gull in a recent photo and include it below with a zoom of Bruce's Nessie. Compare and contrast.

Now whether the bird in the photo is a bona fide member of a gull species seems irrelevant to me. After all, damn! Those are the strangest looking wings I have ever seen on a supposed bird in Bruce's picture. Perhaps it is a weird, cryptid bird like the legendary Thunderbird looking up its watery cousin in Loch Ness?

Quite simply, the sceptics have been suckered into a case of pareidolia here; they see something that looks vaguely like something else. That brings me to a flaw in sceptical logic that is a repeat offence. I call it the "my theory sucks the least" argument and there is normally some fancy Latin  phrase to describe these things, but I am not particularly bothered to find it.

The argument runs like this, the probability of there being one or more large monsters in Loch Ness is approaching zero. So it is not a valid explanation for things we see in photos and films from Loch Ness.

However, since one wishes to look authoritative and intelligent, some kind of explanation needs to be offered as to what is in the picture. Now since any explanation that looks half plausible is going to be more probable than a monster one, it is therefore a probable explanation - use it.

Since the majority are not going to criticise this approach, people will generally get away with it - until they get shot down (like a gull) on this blog and others. So, you declare Bruce's photo is a bird. What do you mean it doesn't look like a bird on closer inspection!? It's more probable than a monster, so that's good enough for me!

Matey, if you think the odds of a monster are a million to one against, but the odds of that thing in the picture being a gull are a thousand to one against, you better just drop both and keep quiet.

This "my theory sucks the least" approach is found all over the place. Another example was Maurice Burton's explanation of the Surgeon's photo. He said it was an otter in the act of diving. It's a daft explanation, but it sucks less than a monster one, so we're cool with that.

I see it all time to varying degrees of dubiety. That does not mean that people do get it right on various pictures (e.g. Steve Feltham outing George Edwards or Alistair Boyd on the Surgeon's Photo), but some others attempts are just ... embarrassing.

More on the man "who invented Nessie"

Or not as the case may be. A commenter pointed out that a Loch Ness researcher had written on Digby George Gerahty over twenty years ago. The researcher was Steuart Campbell, author of the popular book,  "The Loch Ness Monster: The Evidence".

The article was "Who Invented the Loch Ness Monster?" published in the March/April 1992 issue of The Skeptic magazine. Steuart has kindly sent me the scans of these pages which I now include for your interest. You can view the first page and the second page via google drive.

Upcoming Book Event

Gareth Williams, author of the upcoming "A Monstrous Commotion", emailed to inform me that the book will be launched at Waterstones bookshop in Inverness next week on Thursday 12th November at 6:30pm. You can find out more at the Waterstones website. Unfortunately, I am just back from the area and so can't make it, but I am some of our local readers may want to come along.
