The Instrument Towed Array

The Towed Instrument Array is a line with attached instruments (salinity, temperature, oxygen and fluorescence sensors) that is towed behind the ship between the Scanfish (an airlplane-like wing that can be navigated up and down) and a rubber boat (picture).

Zeppelin flight from Berlin to Peenemunde

I arrived at Berlin Schonefeld Airpot on June 16 to fly the Zeppelin to Peenemunde on the northern coast of Germany, from where the team plans to make measurements of the Baltic sea from the air and water. A large press conference to mark the start of the experiment has just finished and we boarded from the airfield around 16.00 hours in clear weather.

The flight was an amazing experience — we floated/ flew about 400 m above Berlin and then onward over the countryside to the northern coast. The zeppelin was flown by two pilots and special permission was obtained to fly over Berlin, which is a no-fly zone.

The zeppelin itself is filled with helium to make it slightly buoyant so that just a little propellor power is sufficient to get it off the ground. It is hard-shelled unlike the soft-shelled blimps. The passenger cabin has huge windows and one can stand up and walk around because it is very stable. There are only 2 Zeppelins in Germany, and 2 bought by Goodyear in the US. This is the first time the platform is being used for oceanic measurements. There are 2 special cameras — one infrared and another hyper spectral that look downward and cover a field of about 32 degrees. They are mounted in a well in the center of the cabin. The cabin is not pressurized, so windows are open and you can stick your head out. We are traveling at a speed of about 60-70 km per hour. It is very nimble in making turns, but also, the ride is very smooth and comfortable. We should be arriving around 7 pm. The landing at Peenemunde was spectacular. The Zeppelin gets attached to the mast of a truck which itself gets footed. The Zeppelin floats just above the ground and can swivel in the breeze.
