150,000 penguins killed after giant iceberg renders colony landlocked

Source: The Guardian

Saturday 13 February 2016 06.56 GMT

An estimated 150,000 Adelie penguins living in Antarctica have died after an iceberg the size of Rome became grounded near their colony, forcing them to trek 60km to the sea for food.

The penguins of Cape Denison in Commonwealth Bay used to live close to a large body of open water. However, in 2010 a colossal iceberg measuring 2900sq km became trapped in the bay, rendering the colony effectively landlocked.

Penguins seeking food must now waddle 60km to the coast to fish. Over the years, the arduous journey has had a devastating effect on the size of the colony.

<snip>

Penguins have been recorded in the area for more than 100 years. But the outlook for the penguins remaining at Cape Denison is dire.

Oh wait, I know. It was science.

Let's watch how this population adapts....we know it will be difficult....let us study......and there is always "we can't interfere"........

Now, tragically, 150,000 are dead.

Now what?

For the same reason you can't bomb icebergs in the North Atlantic.

They are very resilient.

some think nukes are perfectly safe.

For those who know better, drilling a hole and placing charges therein could prove to split the ice without resorting to further polluting the atmosphere with radiation.

Strategically placed conventional charges, even thousands and thousands of them, would not split a flow the size of a US state.

They gather in great colonies:

They travel great distances by scooting on their bellies:

It seems to be their normal mode of travel over the flats. But yes, they are very energetic little penguins. And the most populous of any other penguin. In other words, there's a shit load of them.

It's too bad that, as Robert Falcon Scott once said,

"We are weak, writing is difficult, but for myself, i do not regret this journey ... We took risks, we knew we took them; things have come out against us, and therefore we have no cause for complaint, but to bow to the will of Providence ... Had we lived I should have had a tale to tell of the hardihood, endurance and courage of my companions which would have stirred the heart of every Englishman. These rough notes and our dead bodies must tell the tale."

Robert Falcon Scott (1868-1912)


Try out Ralph Vaughan Williams' Symphonia Antarctica (#7) sometimes. It is about Scott's venture to the South Pole. They all perished within 11 miles of safety, after having discovered that Amundsen had first planted the Norwegian flag at the pole and then made their way nearly all the way back.

Here's a clip from the beginning. It is a chilling work:


Let these things suffice as those penguins' epitaph.

My best.

How do you rid yourself of an iceberg the size of Rome? How do you move that quantity of penguins in such a remote area?

It just seems to me that if mountains can be cut through to make way for highways,... splitting an iceberg should not be outside the realm of possibility.

that I was jabbing you. In my opinion, boring hole through a mountain in habtated areas is relatively easy. But moving such equipment to an area as unreachable and inhospitable as Antarctica is another story.

Cutting through is not realistic.

And assuming you DID cut through, the ice could just refreeze behind you. Wouldn't that be a bitch, to spend billions of dollars and years of time to cut a channel through the berg only to have it refreeze again? Or simply to see the winds that pushed the iceberg into the bay just push the two halves back together again?

As you can see in the video, it is extremely windy. Average velocity of 50 MPH, gusts of 200 have occurred. The cape lies at the bottom of a valley that funnels air spilling off the continent, not unlike a river full of rapids. Mawson called it "The Home of the Blizzard".

(and to be sure, I don't know much more about penguins than anyone else), is that the article implies the penguins have to repeatedly make the trek.

Why isn't it basically a one-time migration of the colony closer to the sea?

After making a 60-km trip a few times, you'd think that they would get the thought that maybe they should move to the new neighborhood permanently.

What am I missing? Look, I'm no expert on penguin biology.

And, not for the first time, here's the Raymond Scott Quintette:

Homing (biology)
From Wikipedia, the free encyclopedia

Homing is the inherent ability of an animal to navigate towards an original location through unfamiliar areas. This location may be either a home territory, or a breeding spot.

Uses

Homing abilities can be used to find the way back to home in a migration. It is often used in reference to going back to a breeding spot seen years before, as in the case of salmon. Homing abilities can also be used to go back to familiar territory when displaced over long distances, such as with the red-bellied newt.

True navigation

Loggerhead sea turtles home both using true navigation and magnetic orientation

Animal navigation

Some animals use true navigation for their homing. This means in familiar areas they will use landmarks such as roads, rivers or mountains when flying, or islands and other landmarks while swimming. However, this only works in familiar territory. Homing pigeons, for example, will often navigate using familiar landmarks, such as roads.[1] Sea turtles will also use landmarks to orient themselves.[2]

Magnetic orientation

Many animals use magnetic orientation based on the Earth's magnetic field to find their way home. This is usually used together with other methods, such as a sun compass, as in bird migration and in the case of turtles. This is also commonly used when no other methods are available, as in the case of lobsters,[3] which live underwater, and mole rats,[4] which home through their underground burrows.

Celestial orientation

Celestial orientation, navigation using the stars, is commonly used for homing. Displaced marbled newts, for example, can only home when stars are visible.[5]

Olfaction

There is evidence that olfaction, or smell, is used in homing with several salamanders, such as the red-bellied newt.[6] Olfaction is also necessary for the homing of salmon.[7]
Topographic memory

Topographic memory, memory of the contours surrounding the destination, is one common method for navigation. This is mainly used by animals with less intelligence, such as molluscs. Limpets use this to find their way back to the home scrape; although whether this is true homing has been disputed.[8]
