German Meteorological Service commemorates the sinking of the Titanic in
April 1912.
Special Morse program with the weather radio transmitter Pinneberg.
In April 1912 the British luxury liner RMS Titanic sank in the North
Atlantic after hitting an iceberg. The German Weather Service (DWD) will
remember exactly 100 years after the disaster at this event. On the night of
14 at 15 April 2012 exudes the weather radio transmitter Pinneberg the DWD a
special Morse code program with the sinking of the Titanic made.
For the special broadcast of the weather radio transmitter interrupts his
regular radio program, write to the Maritime and moves to the 1980s to the
usual Morse procedures. On 15 April is initially from 0030 bis 0400 clock
clock at night (2230 UTC on 14 April to 0200 UTC on 15 April) over the
long-wave transmitter Pinneberg DDH47 (147.3 kHz) a release in English.
During the prescribed periods of distress and associated equipment - each
half hour between the 15th and 18 and between the 45th and 48 Minute - the
names of the 1912 sent out of the misfortune involved in radio officers
slower keying. Licensed amateur radio operators can in the time specified by
the sender DDH / DL0SWA the amateur radio group Seewetteramtes of the DWD in
Hamburg take on short-wave contact.
Take advantage of wireless technology for the national meteorological
services.
The national weather services have benefited particularly from the emerging
wireless technology in 1900. For the first time it was possible to transmit
weather information in a timely manner from remote locations over greater
distances. The meteorologists were able to get a comprehensive picture of
large-scale weather conditions and thereby improve their predictions
significantly. These forecasts and warnings were then distributed to radio
stations to the sailors. The special mission of the DWD is therefore also a
reminder of the great benefits that wireless technology has brought.
The task of the weather radio transmitter Pinneberg the DWD, the
meteorological Safety of Navigation. About the stations are distributed
around the clock weather reports and storm warnings for shipping. For this
he has 14 short-wave transmitters with an output of 1 kW to 20 kW for the
transmission of weather data and weather maps. In addition, a 20 kW long
wave transmitter for radio telex, which also takes over the supply of ships
within a radius of about 3.000 kilometers. Achieved via the so-called NAVTEX
system with medium-wave warnings of the National Weather Service ships on
the East or North road. For the research vessels Meteor and North Star is a
separate radio antenna.
Since the 19th Century, scientists upgraded the German Naval Observatory in
Hamburg sea-going ships with meteorological instruments to enable the
captains and officers of the weather conditions were documented during the
trip. The measurements and observations, they were in meteorological
journals. These journals were on the trip back to the Naval Observatory,
where they were systematically evaluated. The published results were highly
regarded climatological descriptions of sea areas. Sailing instructions
contained therein resulted in faster, safer travel - just like the route of
deliberations today.
Captains possessed in 1912 by Iceberg maps of sea areas.
The meteorological situation 100 years ago was not unusual. Ice fields and
icebergs drifted with the Labrador Current to the south over Newfoundland.
Although the recommended steamer routes considered this situation, the ride
was in this area always involves risks.
A sudden fall in water temperature is a clear indication of the approach to
the ice edge. Experienced captains will reduce the ride and keep lookout
strengthened. There are frequent measurements carried out of the water
temperature in order to observe the passage of the danger zone. The cold
water is also often the risk of dense fog.
Also, historical ships' logs from the DWD report on icebergs.
The meteorological journal of the Titanic is unfortunately no longer exist.
In the archives of the German Weather Service in Hamburg, are archived in
the over 37. 000 journals from the time of the German Naval Observatory, but
there are indications of the ice conditions of April 1912. A total of 34
ships report ice and icebergs. The Titanic was the ship but not more help -
they were too far away, too early or too late at the crash site. In the
journals merely observations of wreckage and life jackets are documented -
silent witnesses of the catastrophe that occurred in the ice of the North
Atlantic 100 years ago.
