helloo!!!!!!

“The olm, or proteus (Proteus anguinus), is a blind amphibian endemic to the subterranean waters of caves of the Dinaric karst of southern Europe. It lives in the waters that flow underground through this extensive limestone region including waters of the Soča river basin near Trieste in Italy, through to southern Slovenia, southwestern Croatia, and Herzegovina. The olm is the only species in its genus Proteus, the only European species of the family Proteidae, and the only European exclusively cave-dwelling chordate. It is also occasionally called the “human fish” by locals because of its human-like skin (translated literally from Slovene: človeška ribica and Croatian: čovječja ribica), as well as “cave salamander” or “white salamander.”

The “piece of wood” (or wooden board)-thing struck me as odd too. It seems clear from the images that the object is not rigid at all (as Susanne Kindström comments with “..by the pattern of movement”). It is clear that the interviewer has nothing but sour grapes for this project and its findings – something very off-putting to me.
Rational inquiry and investigation should be encouraged at all times.

@PhotoExpert
“I was wondering if this is a still digital image, a video captured still or if it is a thermal image from a video capture.”

Looking at the projects homepage (storsjoodjuret.nu), I found this (and translated it):
The system in place today is composed of two Hi-Def cameras, one 3 and one 5 megapixel. A Hi-Def DVD has 720×576 lines of pixels. A 5 megapixel camera from UTS delivers 2048×1536 lines of pixels. [Note: this is what it says on the webpage, I have not fact checked it.]
We also have a camera of 1 megapixel monitoring the station itself. [Apparently to ward off tamperers, thieves and possibly hoaxers.]
The most interesting camera is called FLIR. It is analog, and has limited resolution BUT it is thermographic.
There are also two analog cameras, with “ordinary” resolution.

The system they are using to monitor the input is called Aimetis Aira V5, and is made in Canada. The purpose of this program is to identify “natural” movement, such as rain, and wave motion. It is designed to record only when it detects something “interesting”, which it then targets with the rectangle to log it into the database.

“The rectangle (and it’s red) is nowhere near the object you can see moving in the film.”

The first clip shows a red rectangle, the second (very short) clip shows a blue rectangle (in the lower right corner). I added the comment about the blue rectangle because I was personally confused, since Susanne Kindström states: “It is clear that it contains heat and cells, otherwise [the equipment] would not indicate ‘red’”.

“Xeno, really quickly, does the lake completely freeze over?”

I actually had a hard time pinning this down. From what I remember from living there, all visible parts were indeed solidly frozen over. It freezes over thick enough to drive cars and snowmobiles over much of it.
I searched for a definitive answer, but I failed to find one. It is certainly not completely frozen over every season, what with the latest winters being pretty mild here.
See the fact sheet at the bottom for some detail I did find.

“If not, how many non-air breathing–non-cryptids are there that could get to that size?”

Like I mentioned earlier, eel and catfish are good candidates. I also found out that it is home to both beavers and otters, both of which are notorious for being responsible for “cryptid” sightings. However, you phrase the question with “get to that size” – I have to point out that (as many have already commented) we have NO information about size. Any size references as of yet are purely anecdotal.

FACTS ABOUT STORSJÖN
Storsjön has an area of 464 km² (the fifth largest in Sweden), and a maximum depth of 74m. The average depth, however, is 17.3m. The lake floor is very varied, with many crevices, in parts with a rocky floor, in other parts with mud. In summer, the average temperature of the lake is 12-18 degrees C at the top, and 4-6º C at the bottom. In winter, the average temperature (below the ice, of course) is 4º C.
Storsjön is home to several species of fish including arctic char, grayling, common whitefish and eel. It is also home to two mammals – beavers and otters.
