Rip Current Dye Tracking

Rip currents are among the leading causes of surf injuries along America's coastlines. Learning to identify rip currents is important safety skill for swimmers, surfers and ocean enthusiasts to learn. Scientists from the UNC Coastal Studies Institute and Kill Devil HIlls Ocean Rescue recently used flourescein dye to track rip currents within the surf zone.

That slowness is very deceptive. This only shows how the dye travels through the current and that the current actually is there, the force exerted against a person, especially a moderate swimmer, is substantial. Fantastic video.

It's a very slow rip current by the looks of it (even when speeded up)

NOW I finally know what a riptide is... I think. Looks dangerous

Eff, I almost drown in one of these when a friend and I went swimming in Lake Michigan on a red flag day. I swam out too far to help my friend get to where he could touch, and next thing I know I’m being pulled away from shore further and further, my strength diminishing by the second. First time I felt I would die if someone did not save me. Someone did save me.
I didn’t know what red flag meant. My friends “knew” but they didn’t really KNOW.
Many occurrences like this in early adulthood has made me addicted to the truth and to making sure for myself. I do not just take someone’s word for pretty much anything.
Most people cannot be trusted.

I was terrified at first that it goes out to the sea, then a midly relieved as it comes around

No one:

DDOI: Hello everyone, this is YOUR daily dose of internetㅡ

Could a cheap & natural dye be marketed to swimmers to test an area for rip currents??

Hi, I'm Issei Mori from the University of California, Santa Cruz. Currently, we are working on a rip currents detection algorithm and found your video very interesting. Could you possibly give us permission to use this video on our paper?

[RomboutVersluijs]

Is this an animation on top of the real footage?

[JemeimaRichardson]

Great shot, makes so much sense! would you mind if we used this clip in our water safety course?

[jangrewe]

Can you disclose the amount of fluorescein that was used for this? I'm considering to carry a small vial of it when scuba diving, and it would be great to know what amount creates such an effect. Of course "more is better", but there's no need to overdo it... ;-)

Easiest way to tell a rip current is to look for water pulling back on itself

[thevirgil]

I used that rip to take me out so i could ride the wave in....

[moaquintas]

I heard the best thing to do is to watch another video

I kinda enjoy them and other currents you can experience in the ocean. If you can relax and realize that you aren't going to beat the current swimming directly at it and can collect your thought process without freaking out, and can just remain calm, you are just trying to figure out the puzzle. I grew up being in the water and being a competitive swimmer, I have been a beach lifeguard and I can tell you by experience that most people have horrible swimming abilities, add in almost any negative situation to their already limited abilities and you will get a drowning, or someone in need of rescue, where some will excel and be perfectly fine, others will falter and fail, it all comes down to preparation and remaining calm. What is the first rule in any survival situation? Remain calm, those who can remain calm will most likely survive their ordeal if they can keep a level head.

OR, you can just study how the ripcurrent pulls sediments out into the approaching surf!

Simple to understand the wave 🌊, If there's no wave i think those no wave near in land if there's no wave those part is deep part that's we say it's dangerous to people did not know the true meaning of rip current

Swim parallel to the shore to get out of it

Didn't pull any dye down in significant quantities.
Would watch again.
