Drowning Doesn’t Look Like Drowning

The new captain jumped from the deck, fully dressed, and sprinted through the water. A former lifeguard, he kept his eyes on his victim as he headed straight for the couple swimming between their anchored sportfisher and the beach. I think he thinks youre drowning, the husband said to his wife. They had been splashing each other and she had screamed but now they were just standing, neck-deep on the sand bar. “We’re fine; what is he doing?” she asked, a little annoyed. “We’re fine!” the husband yelled, waving him off, but his captain kept swimming hard. ”Move!” he barked as he sprinted between the stunned owners. Directly behind them, not 10 feet away, their 9-year-old daughter was drowning. Safely above the surface in the arms of the captain, she burst into tears, “Daddy!”
How did this captain know—from 50 feet away—what the father couldn’t recognize from just 10? Drowning is not the violent, splashing call for help that most people expect. The captain was trained to recognize drowning by experts and years of experience. The father, on the other hand, had learned what drowning looks like by watching television. If you spend time on or near the water (hint: that’s all of us) then you should make sure that you and your crew know what to look for whenever people enter the water. Until she cried a tearful, “Daddy,” she hadn’t made a sound. As a former Coast Guard rescue swimmer, I wasn’t surprised at all by this story. Drowning is almost always a deceptively quiet event. The waving, splashing, and yelling that dramatic conditioning (television) prepares us to look for is rarely seen in real life.

The Instinctive Drowning Response—so named by Francesco A. Pia, Ph.D., is what people do to avoid actual or perceived suffocation in the water. And it does not look like most people expect. There is very little splashing, no waving, and no yelling or calls for help of any kind. To get an idea of just how quiet and undramatic from the surface drowning can be, consider this: It is the No. 2 cause of accidental death in children, ages 15 and under (just behind vehicle accidents)—of the approximately 750 children who will drown next year, about 375 of them will do so within 25 yards of a parent or other adult. In some of those drownings, the adult will actually watch the child do it, having no idea it is happening.* Drowning does not look like drowning—Dr. Pia, in an article in the Coast Guard’s On Scene magazine, described the Instinctive Drowning Response like this:

  1. “Except in rare circumstances, drowning people are physiologically unable to call out for help. The respiratory system was designed for breathing. Speech is the secondary or overlaid function. Breathing must be fulfilled before speech occurs.
  2. Drowning people’s mouths alternately sink below and reappear above the surface of the water. The mouths of drowning people are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the drowning people’s mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
  3. Drowning people cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
  4. Throughout the Instinctive Drowning Response, drowning people cannot voluntarily control their arm movements. Physiologically, drowning people who are struggling on the surface of the water cannot stop drowning and perform voluntary movements such as waving for help, moving toward a rescuer, or reaching out for a piece of rescue equipment.
  5. From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. Unless rescued by a trained lifeguard, these drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.”

This doesn’t mean that a person that is yelling for help and thrashing isn’t in real trouble—they are experiencing aquatic distress. Not always present before the Instinctive Drowning Response, aquatic distress doesn’t last long—but unlike true drowning, these victims can still assist in their own rescue. They can grab lifelines, throw rings, etc.

Look for these other signs of drowning when persons are in the water:

  • Head low in the water, mouth at water level
  • Head tilted back with mouth open
  • Eyes glassy and empty, unable to focus
  • Eyes closed
  • Hair over forehead or eyes
  • Not using legs—vertical
  • Hyperventilating or gasping
  • Trying to swim in a particular direction but not making headway
  • Trying to roll over on the back
  • Appear to be climbing an invisible ladder

So if a crew member falls overboard and everything looks OK—don’t be too sure. Sometimes the most common indication that someone is drowning is that they don’t look like they’re drowning. They may just look like they are treading water and looking up at the deck. One way to be sure? Ask them, “Are you all right?” If they can answer at all—they probably are. If they return a blank stare, you may have less than 30 seconds to get to them. And parents—children playing in the water make noise. When they get quiet, you get to them and find out why.

Lady of Orda Cave by Natalia Avseenko and Phototeam.PRO

Two-time world champion free diver Natalia Avseenko ventured deep into Ordynskaya Cave in Perm, Russia… one of the longest and biggest underwater gypsum caves in the world, dressed as the mythical Lady of the Cave, a spirit who protects divers inside the “natural cathedral”.

30 seconds of breathtaking awe at physics – watch a water droplet bounce in ultra-slow-motion. Then, see 7 more everyday things in mesmerizing slow motion.

(↬ Open Culture)

Who knew water could bounce on water?!?

Surface tension is amazing. Phenomena like this are dependent on the size of the drop, of course, so that the mechanical force of falling and bouncing doesn’t overcome the hydrogen bonding that keeps the droplet/surface intact.

Definitely the coolest example of crazy fluid dynamics I’ve seen since these superhydrophobic nanotubes (also in GIF form).

These Glaucilla marginata are blue sea slugs or nudibranches — soft-bodied, marine gastropod mollusks, according to wikipedia —  from the east coast of Australia, but they can also be found along the east and south coast of South Africa, European waters, and Mozambique. The narrator also mentions that they eat “blue bottle” jellyfish, as they are immune to the venom.

A photo of their cousins, the Glaucus Atlanticus, has become popular online recently, with little surprise: they are phenomenal-looking, tiny, dragon-like sea creatures! The kid should see this!

An 86-year-old Yorkshire man, Brendon Grimshaw may have lived alone for many years on the tiny island paradise of Moyenne in the Seychelles in the middle of the Indian Ocean since he bought it in 1962 for £8000, but he is rarely lonely.

For Brendon has spent the years reintroducing the indigenous giant tortoise to Moyenne and now shares the island with 120 of the magnificent creatures, on one of the world’s smallest national parks.

The BBC’s Simon Reeve went to visit him.

Once a hideaway for pirates, the island is now a paradise of accidental conservation! But it took a lot of work in the last 40 years to change it.

He hired his own Man Friday, a Seychellois called Rene Lafortune, who helped him transform Moyenne.

Together they planted palm trees, mango and paw-paw.

They saved rainwater and pumped it up the hillside by hand, or rowed back to the main island to collect a barrel of fresh water.

It was backbreaking, exhausting work. ‘My hands were covered in blisters,’ said Brendon…

Slowly the trees grew and fruited, and eventually water, electricity and a phone cable were piped across from Mahe.

Brendon also encouraged around 2,000 native birds back to the island by feeding them. Forty years very well-spent.

Many species interact in the wild, most often as predator and prey. But recent encounters between humpback whales and bottlenose dolphins reveal a playful side to interspecies interaction. In two different locations in Hawaii, scientists watched as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. The two species seemed to cooperate in the activity, and neither displayed signs of aggression or distress. Whales and dolphins in Hawaiian waters often interact, but playful social activity such as this is extremely rare between species.
