Reader Mail: What the Heck are These Weird Tracks on the Bottom of the Ocean?

Weird tracks on the bottom of the ocean

When it comes to mysteries, there’s no better place for hiding them than the bottom of the ocean. In fact, according to the National Oceanic and Atmospheric Administration (NOAA), as much as 95% of the world’s oceans remain unexplored.

And yet some people don’t believe in sea monsters.

Well, thanks to the advent of the internet, we can do some of that exploring from the comfort of our computer chairs, and you never know what sorts of strange stuff will turn up. Our pal Samuel Burgan (AKA IceBurg) was doing just that, and found a bunch of bizarre markings on the ocean floor, so he sent a few snapshots our way.


Sam writes:

Hey guys, Iceburg here. I don’t know if this is your kind of thing or not but here it goes:

I was playing around with Google Earth a while back and noticed something strange on the ocean floor.

Starting off the East coast off South Carolina, just past the continental shelf, at about 33° 0’10.32″N  75° 9’26.39″W, there are strange tank-like tread marks heading East to West. I initially thought it was just a photo stitching artifact until I followed it all the way to  32°16’38.84″N  55°11’48.71″W, where the tracks stop, make an abrupt turn, then double back to continue on their course.

There are places where the trail crosses other trails. They appear to go all the way to the mid Atlantic ridge, at least that’s where I finally lost them.

Thought they might be satellite sweeps, but they stop and turn around. Wild stuff.

I’ll try to attach some pics. Check it out for yourself.

the weird undersea tracks turn around and cross themselves

The weird markings go on for miles and look almost as if someone has been driving a huge tank on the seafloor, and when I say huge, I mean HUGE. In fact, judging from the size of the tracks, the giant sea-tank would have to have treads around several city blocks wide.

What could be making these strange formations? An undiscovered species of gargantuan underwater eels? Alien spacecraft safely occupying the depths of our oceans? Secret military machinery? It’s hard to not let your mind wander when considering the more fantastic possibilities.

Regardless, I managed to stop daydreaming long enough to do a bit of googling and I might have found at least one possible explanation for the strange drag marks: they might be ship tracks.

According to Google themselves, ship tracks are the leftover traces of an oceanic depth measuring process called “echosounding”. Google previously wrote about the process when many of their users thought they might have stumbled onto remnants of Atlantis on Google Earth several years back.

From their blog:

Picture 6

You see, it’s actually quite hard to measure the depth of the ocean. Sunlight, lasers, and other electromagnetic radiation can travel less than 100 feet below the surface, yet the typical depth in the ocean is more than two and a half miles. Sound waves are more effective. By measuring the time it takes for sound to travel from a ship to the sea floor and back, you can get an idea of how far away the sea floor is. Since this process — known as echosounding — only maps a strip of the sea floor under the ship, the maps it produces often show the path the ship took, hence the “ship tracks.” In this case, the soundings produced by a ship are also about 1% deeper than the data we have in surrounding areas — likely an error — making the tracks stand out more.

While there is a decent chance that this might be what Sam stumbled onto, the only thing that keeps bothering me about the echosounding theory is the second image showing the the tracks turning in on themselves and shifting around all willy-nilly like. One would imagine that boats generally travel in straight lines.

Any ship captains, oceanographers, or underwater alien spacecraft experts want to weight in on IceBurg’s discovery?

Giant sea slugs


the mermaids are getting organized and forming an army to do something about that sonar. I’m rooting for the mer-people.

I think the problem is that you are not looking at a photograph. The maps are a composite of depth information gathered by ship soundings, or other mapping equipment. Where these have been, the data is collected and mapped, and since many of the autonomous equipment just goes back and forth in an area, the data appears in straight lines. Look off the coast of southern CA or near Woods Hole you will see data in similar straight lines. So, the lines are not really there on the sea floor, they are created as part of the mapping process. Where… Read more »

Similar to NAZCA lines….agree?

*sigh* Similar in generating harebrained speculation, yes. But zoom way in on them & it’s boringly apparent that they are strips of ocean bottom, rendered in much higher resolution than the fuzzy low-resolution sea floor around them. The source of that high-res data is, again boringly, sonar scans from ships travelling along the sea surface. The scanning tech covers a stretch of sea floor much wider than the ship itself, which would be a tiny dot in the middle of the path. Thus the convergence of lines on major ports & islands like Hawaii along shipping routes. And thus the… Read more »
I think the key here is that it’s too easy to assume what google earth shows is an accurate representation of what is actually there, when in fact the hundred or so websites about google earth glitches and so on should prove otherwise (i remember the purple crystalline underwater city, and the giant strips of tape holding northern Canada together) Google earth is fully subject to glitches and visual flaws that are a byproduct of how the images are stitched together. No good reason to assume these are anything more than that (in this case, the sonar theory). When someone… Read more »
The ocean is expansive, and we have been to only a very small portion and we we have mapped only a portion as well. These anomalies you see are really from the data captured from ocean vessels that survey that path. Most ships, like aircraft travel in a straight lime for long distances and so you see these long lines running across the floor of the ocean where a ship was surveying as it traveled. Those other areas that have less detail on either side of the line are really low resolution surveys, or even guesstimates. And so, they have… Read more »

these show on google satellite. sonar does not show on satellite images.

Except these are not satellite “images,” at least not ones made by light. Look at the shorelines, you can clearly see where it switches from images to ocean floor height data. The Bahamas really stand out for this.

These ‘tracks’ are the paths boats have taken from harbor to harbor(look at Hawaii going to the mainland) the tracks are a result of the ships radar constantly scanning for obstacles along it’s journey. This means highly detailed images of the sea floor in a line only and these stand out from the rest of the blurred surrounding sea floor which is not scanned. Look at Google earth and turn the sea conservation icons on and you’ll see the boats zigged and zagged on various locations that are monitored and/or protected likely tracking fish or coral reef. The rest obviously… Read more »

Sorry to give a boring scientific explanation, but these markings are the artefacts of sonar mapping. Google Earth is a composite of several satellite and sonar maps, some at high resolution, some low.
Sonar mapping is done as a series of tracks, the scanning done sideways, so individual sonar records appear as lines parallel to, or radiating from, the ship’s track.
A good example is:,-88.6169071,24297m/data=!3m1!1e3?hl=en

in the Bay of Mexico. Here the ship’s track, and the side-scanning sonar pattern, is easily visible.
Sorry, it’s not the handiwork of aliens or a long-lost civilisation.

If they were tank tread tracks they would be uniform in size, shape and width and they wouldn’t abruptly start and stop at the base of the seamounts. If you follow the tracks all the way to the west the tracks narrow to a point.

Holy shit, that’s f…n freaky

squared seafloor… I would be surprised if a fishnet could make such big marks on the bottom. it’s not that they fish with big metal plows right? where talking about a shattered seabed. I think a fishnet could make some marks on the floor but not like this. there are sometimes small mountains across those roads. so fishnets? don’t think so.

That squared site clearly proves that it is sonar(echosounding tracks. If you ever used a fishing sonar one of those lines is pretty much exactly what you see on your screen as a continuous feed as you are moving forward. Showing you the ocean floor as you are going along, you look for underwater structure to fish around. Here clearly they used a sonar to get a general idea of the ocean floor in that area, making a large grid like that instead of ovelapping the passes for a detailed view, but taking 10x as long. If you look closely… Read more »

That line merges with several others in french polynesia…….

Ouchhh !!!

I am not sure but it can be overlapped bathymetry (higher resolution) from some other source than the satellite maps, such as NOAA or GEBCO.

As i carefully look at them i think they were only gap of satellite images where oceans body was not totally capture in all levels.

-My English is basic i hope you get my point. its only my initial observation.

I’ve seen those markings many times. Off the coast of Iceland is a good place to see them. I’ve measured some with Google Earth measurements and many are more than 1000 miles long and in very deep water, ruling out the possibility of dredging, fishing, and other ocean activities. Watching a special on TV, and many were said to be mysterious and too deep to be man made, but definitely not just a natural phenomenon.

ascension island Has tracks all around it..

Notice how the image gets cleaner over geographic structures or areas where the “tracks” go over. This is because it is in fact the sonar imaging; these are clearly the same thing Google explained.




[…] Strange Tracks on the bottom of the ocean […]

I my opinion Google is like many other corps, forced into misinformation. There are human entities that manipulate Natnl Govts, includint U.S. president and congress. If there is any finding that is earth shattering, they will confiscate and then ‘Leprechaun’ it (over supply false readings). Those trackings seem to have been left so long ago, that over time even ocean bottom drifting have covered up part of the track, then reappear over a hundred miles later along the same straight path. There is some commonality in these tracks. They are all an average of 5 miles wide. The most amazing… Read more »

Talk about “so long ago” – this Russian guy just put out a video showing how most of the earth was MINED forever ago… It has blown many people away and could account for these perfectly. I think it’s “There are no forests on flat earth” or something like that… I wouldn’t watch it for a month due to the “flat earth” reference, then started seeing other videos with the same information. It’ll shift your whole outlook, so if you like your head in the sand, don’t watch it!!!

What is that? See link for picture,-167.8142414,180103m/data=!3m1!1e3 You can see tracks from the bottom left corner going up and at the end of it some plane (I don’t know how to name it, such “X” form). Really strange.

Proof that it’s echosounding: if you look at the sea mountains off the coast of Massachusetts these tracks go right over them and it’s only in those tracks that you can see Tue geography in detail. It would also make sense that they went over these mountains to measure the height.

Don’t dismiss an idea just because you don’t think it’s true

I think i may have found a vehicle large enough to make those tracks and it is still on the ocean floor, if it is not a vehicle of some sort it is most definitely something not natural. Check it out at: 34.000343, -119.033221

These lines are off the Northwest coast of the US and Canada as well.

Here is another shot off the coast of the Northwest U.S. (see website)
Dome in center appears to be nearly 2 miles across.

I found an even more interesting site. It’s a “plowed field” at 8 degrees, 25’56” S. by 107 degrees, 59’09.55″ W. The “plowed field” is a 125 by 167 miles rectangle with “roads” that go directly toward Guerrero, Mexico, and San Jose, Costa Rica.

As Tom Freeman states, we are not looking at a photograph, we are looking at a composite of information gathered over many different time frames by many different techniques. This accounts of the variation in resolutions, and that is what this is all about, really. If you take a look at the tracks, you can see that they are only really tracks because they are made up of a line of much higher resolution ‘imagery’ than the surroundings. This is most likely because whatever technique used to record the data was recording at a much higher resolution than whatever, or… Read more »
I think everyone here needs to wake up! Start with the the you tube video: why NASA has not formerly answered why we have not gone back to the moon. Take a close lose look at the moon under high definition mode (in app purchase) in The Apple Solar Walk App, then start recognizing similar crablike objects that are blurred on the ocean floor. The theory is aliens have been mining the moon for some time. Now there is a tank with two wheels that are not completely blurred out if you look closely. It is a 100% clear there… Read more »

Actually, It turns out I was the one who needed to wake up! After posting my thoughts, I soon after realized we are not talking about aliens or even sonar tracks. Unfortunately, I honestly believe mercurybc’s comments following mine and Pascalsnor video is “more on track!”

And this kind of tracks ? Is this sonar too?? 😉


Based on the area, probably being done at the same time as gravity scans to look for oil.

Jonna Mubar (Jedi Apprentice)

Telecommunications cables, they are. Google search you should of maps for telecommunications cables. Match closely, they do. Exact matches they are not, but my source exact it was not.

If these are areas of higher resolution resulting from more accurate sonar scans, it would make sense that those scans are done in area where cables exist or are planned.

So what about geometry track like this,
I dont think its a echo sound from ship track or effects from sonar something…

Actually, VinyageNu’s link, above, to a geometric pattern of trails on the ocean floor provides a very clear & convincing demonstration that these trails are in fact hi-resolution sonar scans for some scientific or industrial purpose. If you zoom in very close, you can readily see that the trails are just hi-resolution scans of a sea floor that around the scan trails is otherwise foggy, because image is from low-resolution scans, maybe be satellite, & smoothed over by Google Maps algorithm — like when you zoom in too far on some remote wilderness spot on land. What the trails in… Read more »

I was searching the ocean floor in the mid to north Atlantic and found something interesting. Lon -54.93 Lat 38.37. These also have lines in geometric shapes, and they are strange and rather large. Just wondering if you know of these and if so, are these also the “feedback Distortion” of the echo sound mapping?

The most interesting and engaging field ever for anyone is oceanography. Enough mysteries to create great philosophers out of dudes

I am going with telecoms cables. The cable laying ships use vigorous kit to disturb the seabed to lay the cable. But there are two difficulties with this idea. 1) the apparent width of the tracks is very wide. Could this be simple collateral disturbance of seabed material? 2) I am looking at a track from Perth all the way in a clear line to the Seychelles but I cant yet find such a route on any submarine able maps.

I thought telecom cables too but look off the coast of Peru. There are shapes formed. No one would lay telecom that way.

Look off the coast of Peru. There are tons of them including one very large square outlined and then two large squares where it looks like the “tracks” (or whatever they are) went all around in an area to make a square shape.

17.6197° S, 149.4842° W and -56.514582, -150.004269 are the start and end point of a line but so many other lines intersect at 17.6197° S, 149.4842° W

Hey me agian. just did research on navy and ship ports around the world and alot of the lines start or end at most of the ports so i am thinking sonar is valid way for this to be a cause of the lines but i dont understand the sharp turns because a ship would have to completly stop and turn to make that sharp of a turn but i am not ruling out it as a possible answer good luck to all people who are doing further research and have fun! 😉

Look west of navajoa mexico in gulf of calfornia. Weird

15.858729, -79.774435 these holes are what??

It’s Joürmongondare the Midgard Serpent

It reminds me of those mysterious holes in Peru!

Talking about holes. Look at 15514785N 78381106V and zooooom in. Wath is that?

It’s the Sphere. The panther explosives Beth set off didn’t destroy it, and it’s just been rolling around on the bottom of the ocean ever since she, Norman and Harry escaped. They could choose to forget, but it’s still down there…….. 😉

well most tracks seem geometric and straight thousands of miles long but today saw tge geometric ones in swirls under the path of the QM2 quite weird and all a little too perfect

mm looking at position of the QM2 today noticed the nice geometric swirls as well as the straight tracks

noticed the swirls under the path of the QM2 today !

those tracks are ancient excavator tracks by giants, in the past the ocean didnt have any water. they mined our earth and took our resources, then a great flood happened and they left.

Hi. I’m a former Hydrographer with NOAA (actually going through the rehire process to get back on with them now). What you are looking at are what we call artifacts (bad data to put it bluntly). These can be due to anything from bad sound speed through water measurements, positioning errors, tidal errors, human error or a myriad of other causes. The reason you see the lines doubling back on each other is because the ships perform surveys on a small scales which are then put together to get the whole picture. So think of mowing the lawn back and… Read more »

Just an observation…these very tracks lead from mid-central Chile to Easter Island in the Pacific. How curious is it that an area on Easter Island is named Centro Artesanol meaning Central Craft or Center Craft.

Hey just saw more “tracks” west of the fiji island. I saw those and googled it and found this page

Those are not machine tracks. The ocean floor is riddled with rifts that are caused by continental drift.

Mmm intriguing. Like you Greg I’d be inclined to go with the echo sounding explanation but every now and then you see manoeuvering patterns which seem to defy the logic of such a scenario. That and they also disturb me somewhat because they remind me of these recurring dreams I’ve been having for years now where I’m wand’ring in and out the Mersey along the beds of the seas and oceans of the world where I keep bumping into there’re all these endless dead people blindly shuffling along. The most recent highly detailed one from about 18 months 2 years… Read more »

The “Echo Sounding Theory” is pure non-sense: since when does SOUND make SHADOWS? Look at the photo, the light source is from the bottom of the pic. You’re trying to tell me that a boat made this triangular shape with its echo sounder, then later on a photo-satellite going over picked up its residual echo sounding and that it had manifested itself into a solid in order to cast a shadow? C what I mean about pure BS?

Since at least the US Civil War.

These are bathymetric surveys; i.e. depth of the water, using echosounding; they are not photographic images. Where on Earth did you get the idea these are shadows cast by light?

thank you. really. it’s nice to have at least a modicum of reason, and some level of knowledge (and productive informed skepticism, i think?), in these comments…

Thats called artificial hillshading mainly used by marine geologists to get an idea of the slope (

They are not echo sounder tracks.Echo sounders use sound waves which make no impression on the sea floor. They are not trawlers nets, or the doors, because they do not strike the bottom often and do not result in straight lines of that nature ever.When are people going to finally understand we have alien species living on this planet. They reside in lakes and the ocean. They are mining for minerals and sampling sediment for their own purposes. Try reading Timothy Good’s books or The Third Explanation Amazon Kindle. Wake up and smell the ozone people!

Brian, with all/any due respect, lay of the smoke dude.

“which make no impression on the sea floor.”

If you think that is the point, your logic centres are severely flawed.

What a load of crap

At least ten years of my time was spent as a science journalist. There may (or may not be) a good explanation for these tracks. No one however has come up with a realistic one yet. The point is, it doesn’t take a lot of research to realise we are not alone. It does however take an interest in science and an open mind. Michio Kaku once said, “A species a 1000 years ahead of us would look just like magic, 500,000 would take them anywhere they wanted to go, and do anything they wanted to do – anywhere!” Are… Read more »

Ancient roadways of past civilizations perhaps???

Using standard aerial photo techniques, those “tracks” are are more like super-wide construction roadways complete with strange shaped buildings and vehicles on them. There are tall structures on & alongside the roads. This could be some kind of manufacturing site. A big site!

Note how the individual road segments goes down inside the small craters & cracks; this rules out a large tracked vehicle making these marks, because it would span the hole, leaving no track-mark down inside. The tracks look as if constructed in long single rolls from the inside roll out.
