It’s been used by thousands of clients for different things. Chrysler was one of the first, a big double-page ad in a dozen magazines. He advertised in graphic design manuals and sent out direct mailers. How did this iceberg photograph get so widespread ?īy the time we finished creating the iceberg, Craig already had a marketing plan for it. Nautilus Members enjoy an ad-free experience. We created what at that time was an enormous file, eight megapixels. This is pretty early in the days of Photoshop. Craig Aurness, who ran the stock photo agency I worked for, told me to research what a real iceberg would look like, the physics of how it would float in the water, so we could get it accurate. I just cut out a section of an iceberg and then flipped it and put it underwater. I took the picture of the bottom part of the iceberg in Alaska, above water. I took the picture of the top part of the iceberg in Antarctica when I was there on assignment. The shot of the clouds was taken here in Santa Barbara. The image is composed of four separate pictures. How did you capture such a majestic-looking iceberg? From his home in Santa Barbara, California, Clevenger had a chat with Nautilus about the origins and remarkable longevity of his most famous picture-as well as how it was photoshopped. When it came out, it was actually pretty original. A professional photographer for more than three decades, he’s shot for National Geographic, Outside, Audubon, and other magazines, yet he says this image is still what he’s most known for. The iceberg’s hidden bulk takes on an air of mystery and as-yet unrealized potential, making it a powerful metaphor-and a money-maker. The expression, and the photo, have become a mainstay of inspirational posters, expressing concepts like success, imagination, and the human condition. The man and his million-dollar photo: Ralph Clevenger next to the photo he created. Ralph Clevenger, below, is the man who took it. If you Google image search “iceberg,” or even “tip of,” it’s the first one that comes up. Over the past 20 years, one photograph has become associated with the cliché more than any other. Multiple overtones are visible in the spectrogram.What do the Volkswagen diesel scandal and the European migrant crisis have in common? They’ve both been referred to as the “tip of the iceberg.” The popular expression reflects the fact that, as impressive as the visible portion of an iceberg is, the vast majority of it (usually about 90%) is underwater. This spectrogram has a fundamental frequency of 40 Hz, with a 40 Hz overtone spacing. Generated by iceberg in contact with the seafloor or other iceberg. The calving signal is short duration, broad band from 1-440 Hz generated by ice cracking and crack propagation. Original icequake (bloop) sound: Recorded signal sped up 16 times.Ĭalving: Spectrogram of an iceberg calving (large section of iceberg breaking off) while adrift. Based on the arrival azimuth, the iceberg(s) generating “Bloop” most likely were between Bransfield Straits and the Ross Sea, or possibly at Cape Adare, a well know source of cryogenic signals. Icequakes are of sufficient amplitude to be detected on multiple sensors at a range of over 5000 km. The icequakes were used to acoustically track iceberg A53a as it disintegrated near South Georgia Island in early 2008. NOAA hydrophones deployed in the Scotia Sea detected numerous icequakes with spectrograms very similar to “Bloop”. The broad spectrum sounds recorded in the summer of 1997 are consistent with icequakes generated by large icebergs as they crack and fracture.
