NASA releases photo of weird rectangular iceberg

Operation IceBridge, NASA’s longest-running aerial survey of polar ice, carried a flight over the northern Antarctic Peninsula on Oct. 16, 2018. During the flight, IceBridge senior support scientist Jeremy Harbeck spotted two rectangular icebergs floating among sea ice just off of the Larsen C ice shelf.

“I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I’ve not really seen one before with two corners at such right angles like this one had,” Harbeck said.

The rectangular iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the massive A68 iceberg, a chunk of ice about the size of the state of Delaware.

“I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple photos,” Harbeck said.

The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began Oct. 10 and is scheduled to conclude Nov. 18.

Always thought H2O had hexagonal crystals.

Reply to  Bob Hoye
October 23, 2018 1:13 pm

Only approximately. The angle between two hydrogens is 104.45 degrees, not 120 degrees.

Roger Taguchi
Reply to  Curious George
October 23, 2018 2:06 pm

Hexagonal crystals form in ice-I (the most common form of ice) because the H2O molecules are hydrogen-bonded together into roughly cyclohexane chair conformations, an oxygen atom occupying the position of each carbon atom in cyclohexane, C6H12: see https://en.wikipedia.org/wiki/Cyclohexane_conformation . Carbon atoms form 4 bonds each, at roughly tetrahedral angles (109.47 degrees). Since oxygen atoms form only 2 covalent bonds each, two of the 4 directions are to covalently bonded hydrogen atoms in an H2O molecule, and the other two directions are in longer “hydrogen bonds” to H atoms in other H2O molecules. Looked at along the C3 axis of symmetry, one sees hexagonal cross-sections, so the 120 degrees is not directly related to the H-O-H bond angle. In ice crystals, the 104.45 degree bond angle in a gas phase (isolated) molecule is opened up to around 106.6 degrees, not quite equal to the tetrahedral angle, so the hydrogen bonded atoms are not all on the same straight line as covalently bonded atoms (see http://www1.lsbu.ac.uk/water/hexagonal_ice.html ).

Jeremy Harbeck said he saw 2 rectangular icebergs. One, he said, had 2 corners that were extremely square. It appears the top photo is showing an iceberg with a very straight edge between 2 very square corners, but the far end is not visible.

The 2nd photo shows an iceberg without such a straight edge and with more rounded corners. This may be the 2nd iceberg. If the berg partially visible in the upper left corner of the photo is the far end of the 1st berg, the photo discrepancies go away.

Its an untested belief of mine, that large blocks are broken off the ice sheet by the effect of tsunami. While the height of the wave may only be a foot or so, it could be enough to snap off a block along the wave front. The shape of the sea floor and an element of chance then decides how the lateral stresses square the block off.

Two right angles do make a square or a rectangle. Did you not take geometry? A right angle has two legs not one. Now if they had said two corners then you would have a point.

ln the top photo there is a smaller ice berg in the bottom lefthand corner of the photo. Now that smaller ice berg fits in with the scene and looks true to life. Now if you compare that small berg ice to the large main one. Then the main ice berg just does not look right, its looking just far too neat and tidy to what would be expected in a real setting.

Hello esteemed “experts”, this is not an iceberg, it is an ice island. Google it! The difference between the two is relatively minor but becomes important when commenting on its shape.

Most ice island have geometric shapes with straight edges. By definition, they are flat-topped. This one is cute but not unexpected.
