A robot explores the dark, cold, deep sea floor of the South Atlantic, transmitting images of vibrant coral and fish never seen before as scientists give live commentary via YouTube. And Argentines can’t get enough of it.

The Argentine-American scientific mission is for the first time exploring the Mar del Plata Canyon, a submarine gorge which plunges nearly 4000m deep off the coast of the seaside resort of the same name.

The awed conversations between scientists leading the expedition and the explanations they give to viewers allow the public a rare insight into the hidden wonders of marine biology.

In one instance, the camera on the SuBastian underwater robot shows a little, weird-looking, white animal. One of the scientists on the team can be heard asking her colleagues, “Do we want it?”

“Yes, yes, we want it!” reply dozens of messages in the livestream chat before the image shows the suction device being activated to suck up the specimen for study.

“Oh, I love these little creatures,” one user said. “I’m obsessed!” another commented. “Don’t take the little one away!” a third pleaded.

The livestream began a week ago and exceeded one million views per day since Thursday (local time), when it also began to be broadcast on television.

“There are cold-water corals with the same colours as those in the Caribbean. How can that be? At a depth of 3000 metres!” Pablo Penchaszadeh, a marine biologist and painter who is on board the expedition as an artist, told AFP.

Patrick Star

The 20-day expedition Underwater Oases of the Mar del Plata Canyon involves 25 scientists – most of them from the Argentine research agency Conicet.

Part of the Gempa deep sea study group, with support from the US Schmidt Ocean Institute, it will end on August 10.

Aboard the Schmidt Ocean Institute’s RV Falkor (too) ship, scientists remotely operate the robot, which can descend to a depth of 4500m.

They collect biological samples with its robotic arms and other instruments, and send back high-definition images.

“The fact that anyone can connect from home and see what we are seeing live is a unique opportunity,” expedition leader Daniel Lauretta said in a statement.

“Science is no longer something distant or inaccessible, but becomes part of everyday life.”

This week, social media users were delighted when an orange starfish with two symmetrical bumps resembling buttocks appeared on the livestream. It quickly prompted comparisons with Patrick Star, from the popular animated series SpongeBob SquarePants.

Memes circulated joking that “Patrick is Argentine”, marine biology became a trending topic on social media and the broadcast reached the screens of hundreds of thousands of captivated viewers.

“I came to see the big-bottomed star, is it here?” asked one user upon entering the YouTube chat.

Spectators also gave other sea creatures nicknames: a king crab was dubbed “Drag Queen” and a sea cucumber was fondly called “Sweet Potato”.

‘Beacon of light’

This is the first time that human eyes – albeit remotely – have in real time seen this underwater oasis, where the cold, nutrient-rich Malvinas current and warm, salty Brazil current converge.

The confluence is “one of the most energetic regions in our global Ocean”, the website of the Schmidt Institute said, with the temperature difference creating an area teeming with marine wildlife and flora.

“We are already seeing incredible things: animals that have never been recorded in this area, underwater landscapes that look like something from another planet, and behaviours that surprise even the most experienced scientists,” Lauretta said.

But funding for such expeditions is under threat in Argentina.

Conicet, the Government’s scientific research arm, has been severely underfunded by libertarian President Javier Milei, who has implemented draconian cuts to public spending with his infamous “chainsaw”.

Its budget fell by 21% last year, salaries have plummeted by 35% since Milei took office in December 2023, and the cuts have led to an exodus of scientists.

As a result, in between “oohs” and “aahs” of wonder, messages of support are flooding the livestream’s chat: “Long live Conicet!”.

“Seeing people being passionate about their job is attractive,” Tomas Atilio Luppi, a biologist at the Conicet-affiliated marine and coastal research institute in Mar del Plata, who is not directly involved in the campaign, said.

“This is happening at a very difficult time,” he told AFP of the popular broadcast. “Science is in a very complicated position, both financially and in terms of support and human resources.”

“The fact that this craze is happening is like a beacon of light.”
