Why icebergs float in the ocean

I particularly loved the second chapter of this book. This fading alerted every single art curator in Amsterdam, and was eventually all over the news.

If you know your science and you are considering getting a copy — this book is not for you. You are just going to find some curiosities you probably already knew. If, on the other hand, you wish you knew more about science, you will certainly love this book.

You may encounter some complicated words like phospholipids, cloxacillin or electromagnetism. It also contains a slew of additional resources to keep pursuing your interest in science.

This tweet soon went viral, with many glaciologists praising her for finally setting the record straight on how an iceberg actually floats. Today I channeled my energy into this very unofficial but passionate petition for scientists to start drawing icebergs in their stable orientations. I went to the trouble of painting a stable iceberg with my watercolors, so plz hear me out.

A day later, Josh Tauberer , a software developer and civic technologist, created an interactive website where people can draw their own theoretical iceberg and see how it would float in the ocean.

Soon after the Titanic sank, an International Ice Patrol was established to track icebergs and warn ships. That patrol continues today. Iceberg patrols now use global positioning system GPS technology to help locate icebergs and prevent more tragedies like the Titanic.

It was found drifting toward the Drake Passage, an important shipping route south of Argentina. David Long of NASA's SeaWinds science team used satellite data to track the iceberg, the first time satellite technology was used for that purpose.

Since that time, the SeaWinds team has used satellites to track the world's ice. Icebergs that drift into warmer waters eventually melt. Scientists estimate the lifespan of an iceberg, from first snowfall on a glacier to final melting in the ocean, to be as long as 3, years. Photograph by Dennis Lowe , My Shot. Why So Blue? Some glaciers and icebergs are blue, for the same reason water is blue. The chemical bond between oxygen and hydrogen in water absorbs light in the red end of the visible light spectrum.

Blue glaciers and icebergs are not blue for the same reason the sky is blue. The sky is blue due to atmospheric scattering of light Raleigh scattering , a different phenomenon. Iceberg Prose The American novelist Ernest Hemingway is famous for his writing style of short sentences. Hemingway, in fact, compared his writing style to icebergs.

Just like an iceberg remains largely unseen beneath the surface, a writer can leave parts of a story unwritten. Hemingway believed the reader would understand and be affected by the unwritten parts of a story as well as parts that were actually written.
