NORTH ATLANTIC ICE FLOWS

WHERE WE AT?

Looking out the passenger window of the airplane, I noticed these clouds. Awesome compressed weather pattern…like a low pressure system or hurricane.

Wait! Those aren’t clouds, they are icebergs! We are about 200 miles south of Greenland at 45,000 feet. That’s a little more than 7 miles in the sky. For reference, those icebergs are on average 3.3 to 246.1 feet above sea level and are actually 3 times that height if you include the submerged portion of the berg.

Most of these icebergs were coming from western Greenland…which is ironic because the island is covered in ice (Iceland is actually very green…oh the irony!).

One of the things that I found interesting about icebergs and sea ice, is that icebergs leave “shadows” of broken ice behind it. So my question to you is…

1. Are the icebergs moving? Are the icebergs being blown by the winds like an old tall ship and breaking the sea ice?

OR

2. Is the sea ice moving past the icebergs?

Well the icebergs aren’t moving as much because they act like a sea anchor. Recall that 2/3’s of an iceberg is below the surface…so they don’t move as much as the surface ice. The sea ice drifts with the winds and the currents…less is below the surface to slow it down. The interesting pattern (the swirl) is the current influence…and the wind.

All righty then…so approximately where was this place in the middle of nowhere…200 NM to the south of the southern tip of Greenland…

HOW DID I DO THAT?!

This shot was midday out a window…so reflections are a concern. I shifted the camera around until I got a shot with no reflection. ISO was at 200…the lowest I could get my camera for bright conditions such as midday sun.

Next, I wanted a deep depth of field so I set the aperture to f/10 and the light meter was balanced with  the shutter speed set to 1/250s.
