People 'terrified' after seeing what happened when woman dropped GoPro to bottom of the ocean

You might be best off looking away now if you're not a fan of the ocean, as this GoPro footage from the seabed has left people freaked out.

Alexis Westland, a keen sailor from the US, decided to do us all a solid and drop her waterproof camera into the depths in Marina del Rey, Los Angeles.

She explained she had been heading out to practice when she decided to make a brief diversion to capture some underwater content.

The YouTuber didn't drop the exact coordinates of where she deployed the GoPro, however, Marina del Rey directly connects to the Pacific Ocean.

Therefore, watching the footage allows you to experience what a trip below the surface in the largest and deepest ocean is like - while keeping your feet firmly on dry land.

Despite the more than 233,000 people who have watched the video doing so from the safety of the shore, loads of viewers have still been left absolutely terrified by what Alexis captured.

The GoPro was left at the bottom of the water for 'a couple of hours', according to the sailor.

But she barely captured any activity while recording, which is exactly why social media users have been left so scared as they just can't believe how eerily quiet it is below the surface in Marina del Rey.

There's not an aquatic creature in sight during the 12-minute clip, despite most people saying they were expecting some kind of sea monster to pop out any second.

Instead, viewers are left staring at the green hues of the water until the GoPro finally reaches the bottom and lands on the seabed.

Apart from the continuous movement of the sand which blankets the ocean floor, there's very little activity.

Visually, that's about as exciting as it gets, but the audio picked up by Alexis' camera is a lot more intriguing.

In the caption of her video, she explained that there's a 'distinct humming sound' heard throughout the video, which rings out even after she had 'motored away' and headed to sailing practice.

Alexis added: "I wonder what that was?"

As well as speculating about the source of the strange sound, viewers flooded the comments with their thoughts on the bleakness of the bottom of the ocean.

One person said: "This was making me so anxious, anyone else?"

Another added: "I'm terrified of the ocean. Just thinking about it scares me. Yet here I am, scaring myself by watching this video."

A third joked: "This video is what I call the 'you get dumped into the ocean and left for dead as the boat leaves you simulator'."

A fourth wrote: "Look at that current! Strong enough to toss that camera around like tumbleweed."

And a fifth said: "The vast emptiness of cloudy water is what gets me. Just waiting to see something freaky."

Others shared some suggestions regarding what the eerie noise in the footage might be.

"When snorkelling, sometimes far from any boats, you can hear the same sound," one person commented. "It travels a lot further underwater than in air, I guess."

A second laughed: "Wtf it sounds like a damn lawn mower..."

And a third speculated that 'oil rigs and pipeline drilling' might be to blame.
