- Location: Old Lyme, CT coastal wetlands, 1934-2016. (Note to teachers: this video is NOT designed for use in elementary-age instruction or similar settings).
Photo #timelapse of #erosion with original music. Aerial view of re-shaping and land loss (with some deposition also visible) on the shoreline, beaches, and tidal salt marshes near the mouth of the Connecticut River at its juncture with the Long Island Sound. Local seaside landmarks affected include Griswold Point, the Black Hall River, Griswold Cove, White Sands beach, and Great Island (including Poverty Point). The video shows the levels of environmental impacts from multiple hurricanes, tropical storms, and other natural weather-related events to which the regional climate is susceptible and which accelerate the process, including the 1938 hurricane, Hurricane Carol, Hurricane Gloria, Hurricane Bob, Hurricane Irene, and Hurricane Sandy.

At far right there are rock levees place in front of the homes. The beach extends out from the old shore line and gains depth. The levees push the sand that is "migrating" down the beach out into deeper water where it can not now replenish the sand bar at the mouth of the river. A small change to save the beach in front of the homes causes lose down stream of the "improvement". Coastal areas are by their nature transient at best in short and long time scales - add in a hard feature and you get this.
Q predicted this.
Levees aim to control the flow of water. These are groins. Groins are built to "dam" the longshore transport of sand driven by wave action. Groins are not designed to push sand into deeper water, but after sufficient sand has accumulated against a groin, sand will make it's way around around the tip of a groin, where the depth is indeed greater, but that is not what they were built to do. It just happens as an inadvertent consequence of groin construction.
When comparing between year 1934 and year 1986, after watching the changes (rather than progression) between those two years, I see that 1986 basically returned to the 1934 images. In other words, I have to believe that this might not be erosion as much as changes naturally occuring with or without humans around. These changes are now more prevelant but it will intersting to see in the future if honest people continue to provide undoctored data, that is; apples with apples images (such as taking them at the same time and date of the year) each year. .
Bingo
Agreed. Natural occurring land barriers are there to do just that, move.
Agreed well said. The world is forever changing.
Gasp 😱 and in 1834 the beach looked much different as well.
Wgaf
@@jhljhl2207 your mom
Sand bar movement yes, no significant erosion to property.
Tell the people in Holland that! Last year we had to make a bigger beach due to erosion!
@@barrymantz6026 brilliant engineering in Holland.
That's what's known as "shifting sands" NOT erosion.. But looks good all the same.
The three groins designed to stop sand shifting to the left destroyed the natural process leading to the break in the coast line. Man made problem.
Yep 😭
Most importantly, we do not know if all of these images were taken at the same tide level. The difference between high and low tide will change the profile of the beach dramatically in photographs, even if compared in only one day, no less over 50 years.
A clear demonstration of why it's very unwise to build on barrier islands or dunes - but it's been done along a great many coastlines anyway.
Why not place a dashed 1934 beach outline, so as to show us the extent of the advancing erosion?
Amateur hour time lapse making.
Too much work.
Shifting sand is shifting sand. It is all natural.
Nothing to do with climate change. This has been happening for centuries if not millenniums.
@@gerardburton1081 It just means the sea level is rising.
Curious? Try this as an alternative hypothesis. When silt and sand stops flowing out of a river the beach disappears. Up river stabilization leads to beach erosion.
This is because currents are continually moving sand away.
You certainly made a big mistake. Beach erosion is nothing to do with river. Beach erosion is caused by the ocean current. There are two types of current.
Constructive current brings and deposits sand on the beach.
Destructive current washes and takes away sand from the beach.
In this case Old Lyme should have destructive current and caused the beach erosion.

Where does sand come from if not from rivers?
@@johnha2432
The video is solely focused on a river end, dumping into the ocean.
... I guess you missed that.
@@kevingooley6189 It's coming across the beach from the right to the left in these pictures. The river outlet has been skewed left by this continuing right-left deposition of sand. The breakwaters in front of the houses send the sand coming across the beach into deeper water, not replenishing the sandbar.
A storm (probably) breaks it, losing half of it's length, then another (probably) sweeps away the accumulating sand from the two island near the centre of picture.
That's wild, 90 to 2000 it changed dramatically. The rivers and jank changing, pretty cool. Power of water.
great piece of music
well, that didn't change much.
The earth just doing what the earth was designed to do. Nothing is permanent....NOTHING ! The only thing permanent is .... CHANGE !
I saw more of beach movement than erosion. That straight peninsula became an L shaped peninsula.
Normal. Yet we always blame ourselves like we are special and powerful.
I wish that there had been several series of rapid switches between scenes like an old time flicker movie so I could have seen the erosion. I could not fathom the changes between slides because it was so slow. Great concept though. I do agree that it is a natural process that has been made into a story by the encroachment of man on natural processes AGAIN.
Wasn't a beach it was a sand bar
Wow, how did they get “satellite” photos in the 30’s 😐
Only the most recent images are satellite. The early ones are actual aerial photographs from a statewide airplane survey over many decades beginning in the 1930s.
This is not a rising ocean. It is probably the result of daming upriver which stops the sediment from flowing to the ocean.
I looked, there are at least two dams upstream
And levees up the coast - see the right edge sand piles up and gets deeper then when full pushes the sand to deeper water.
The ocean is indeed rising, most places 9 inches per century going back hundreds of years
What did you think was going to happen after the construction of the Groins? As soon as they were installed, the longshore current could not replace the western movement of sand. Starving the replenishment. In the future, when you see groins installed, buy the property in front of them because their beach will always grow but the down stream houses lose all of their property.
That's an awesome video that shows the power of Mother Nature! Thank you : )
And human power by their engineering and constructing 2 dams upstream to block and interfere with Mother Nature's sediment flow to the ocean for 85 years. This is not rising sea levels..
WHO IS THIS MAKE BELIEVE PERSON YOU SPEAK OF?............"cheers!"
When you can absorb in your brain that the ocean makes up three quarters of the planet and the continents are constantly moving, and some in a downward direction it's going to look different over time. It's all the NORMAL evolution of the planet. God is so good.
Eh gods alright I guess.
Just the mouth of a river inlet doing what it does. One flood or storm would was it out and then over a year or two gentle waves and alongshore currents bring it back
It's weird where they filled in the swimming pool after 1965 and changed into a green space which has remained green, and everything else was green has been built and paved over.
Grew up in Old lyme still
Live there today I’ve found some nice old coins out there!
The point looked the same later as in 1934 there was also the hurricane of 1938
Been a long time, Mark. Good to hear from you again, we used to fish at the eightmile with my grandpa Don. Those were fun evenings, hope you’ve been well.
@@johndante87 what’s your last name ? Were you class of 1987?
So what? It's just a natural process. The sad, nostalgic music is totally misplaced here. Things erode. So what? It's akin to crying over a rusty fence.
P Lucas it’s apart of a bigger problem which can harm coastal villages and populated areas near the coastline, millions of dollars of government spending is spent every year just to prevent this “rusting fence”
Yes of course... if the problem is not immediately obvious to you, it does not exist!
Uh, yep. The Earth changes.
Woooow bad man keep it up mate 👌👌👌
Connecticut is a pretty Liberal, Eco-consious area of highly educated affluent citizens . Notice how while they tout the hazards of global warming , rising of sea levels and the danger of overpopulation the housing development in the lower right corner becomes congested over the span of this segment.
Well this video has nothing to do with global warming.
You also have to take into consideration the fact that the eastern end of North America is slowly sinking into the Atlantic Ocean by about 1 mm per year. After 82 years, that's 8.2 centimeters, or 3.5 inches difference.
Wow, I need to read more about subduction zones!
@@bryanchandler3486 It's not about subduction. That's where two mantle plates collide. During the last ice age, the huge weight of the glacier that covered much of North America caused the central portion of the continent to depress. Once the ice melted, the central portion of North America began slowly rising, and the eastern part of the continent is slowly sinking into the Atlantic Ocean. Global warming compounds the problem, but the eastern part of North America will continue to sink, and there is nothing we can do about it.
Beach erosion is nothing to do with river. Beach erosion is caused by the ocean current. There are two types of current.
Constructive current brings and deposits sand on the beach.
Destructive current washes and takes away sand from the beach.
In this case Old Lyme should have destructive current and caused the beach erosion.
Cutting through the sandbar to let water out of the lagoon does seem to have a longer term destructive effect.
So no beach erosion after all.
You can see it better if you speed it up to 1.5x
After once through, I paused it and then used the floating preview window to move to each period as a still. It made it easy to compare periods in sequence that I wanted to.
the spit at the bottom left of the screen get longer until water erode section of it and it disapeared and a new spit is formed and an island joined the spit
Actually, it is just the ability of the person drawing these pictures that is eroding....
Lmao 😂 you think this is fake? Holy shit.
That erosion is caused by a latch or erosion at the houses. It’s swapped one for the other.
A sand bar does vary over time
I didn’t see shit lol
Geologists only talk and think in millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So every layer on our planet contains material with the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay and meteorites. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
that is so crazy to watch!
who got this recommended 5 years later?
Wow, shit went sideways from 1995 to 2004
so, basically, not much change
It's a river mouth/delta..they change over time
EROSION HAPPENS...THIS IS RUN OFF FROM MELTING SNOW......."cheers!"
It would be good in a faster time-lapse on repeat
Now, we can see how small the land will be in ten million years
Wait? Ten million? Extrapolate back, what would have happened if this area was even just one million? That's over 12,000 times more erosion than what you saw in this video. Take a look at the documentary "Operation Lighthouse Rescue" and see what has actually been recored in just the last 300 years. PS, Love the name! My Ravens everywhere rely on you in winter...
I'm imagining that within millions of years, the Midwest will probably be coastal land.
Neat video
what camera has been up there that long recording that
Interesting photos for discussion. Also interesting are some of the comments where people ascribe an "agenda" to this presentation or dive off the deep end with generalizations about liberal, environmentalist Connecticut citizens. I guess people just can't help themselves sometimes.
Now I would like to see a collection of time lapse photos for the Louisiana coastline. Whole villages are nearly gone - storms, rising sea level, and land subsidence are all taking their toll over just 70 years.
I was expecting something more dramatic.
The sea gives and takes....
Mother Nature does what she wants. Volcanos exploding, earth quakes constantly occurring, and every natural disaster that occurs with every exploding volcano changes the land scape. ALL THE MONEY IN THE WORLD or having mankind removed will not change Mother Natures ways….
Maybe the loss of salt marshes has an effect. Human encroachment into natural areas.
The origins of Lyne disease
It's quite sad really, for something we don't see visually if we didn't have satellites.
Alot of the picture where from planes. We didn't have satellites in the 1930s.
if ur in school seeing this. wassup
God has a plan 🙏 Amen 🙏 🙌 ✨ ❤ ☺ 👏 🙏 🙌 ✨ ❤ ☺ 👏
Wow😯
Actually, not nearly as bad as I’ve seen from other coastal areas.
COVID cured everything.
Seems like erosion has occurred since the first rain.
Wow, very sad
Duh!!! It’s sand what did you expect?
The beach is not so much eroding...as it is the land is sinking into the ocean. You should look up such things.
So no change. K.
IF THERE IS SUCH CONCERN ABOUT THE OCEANS RISING, WHY DID BARRY SOETORO PURCHASE A MULTI-MILLION DOLLAR HOME ON THE BEACH?........."cheers!"
Really reaching on this one
Reaching? This is natural erosion.
I’ve been going to Florida my whole life and the beaches literally have not moved. It’s all the same. So this is not significant for the amount of years that went by.
That's because this isn't caused by rising sea levels.
when water was water
If you can come up with any ideas on how to stop the ocean. I'd say quit building so close to it.
What? This is erosion from the river.
So, if they weren't 'great people.'?
Did an adult review this video prior to release? People come to sites like this to be educated and horrible music is played instead of having educational narration? Uhmm?
Where is this?
Sand bar changes. Nothing to see here
Coast lines. They change. Simple As
Looks like you lost what ever was feeding sand to the beach.
Where did you get those images?
The Great Gazoo.
I'm not seeing it
Its normal
How about 2022
Caused by the removal of the pay phone booths……really.
The city looks same bruh
Isn't erosion, is all about cycles of creation and destruction over and over in a cycles of 27000 year's, wake up human's you don't even knows were you live.
Is this a joke? There's hardly any change at all. Clickbait.
Yeah, this is the type of science I want to see more of! I've been studying rain water erosion and it's affects since 1976, and I got to tell you it is happening 10 to 100 times faster than the 1800's science we are slaves to. Real science, in real time. I wish my home state of California had paid more attention to this issue earlier!

Gee…thanks for the erosion. And…the tick borne illness.
Sooo. Suggesting the photos taken from the Exact same spot. For 82 yrs... Not buying it. Sorry.
Not 82 years dummy... it looks like they took about 12 pictures over 82 years.
These photos were taken over a time period of 82 years. Not sure what the issue is here.
i have a great beach house for sale if anyone is interested?
Didn't change much
I don’t see any difference.
Didn't notice anything.
Looks the same
Oh my God its global warming!!!!
p
All looks the same
People be like *SHOCKING NEW GLOBAL WARMING PROOF, MUST SEE!*
