We're on the map!
(Posted by Melanie, campaigner on board the Arctic Sunrise:)
I spend waaaaay too much time in the office of this ship chained to my
laptop, but sometimes sitting here in the office of the Arctic Sunrise
has its benefits.
Take two minutes ago when Arne Sorensen, our ice pilot, came into the
office. Arne's job is to maneuver the ship through ice, which may sound
simple, but trust me, it's not. It takes an intimate knowledge of and
experience with wind, weather, the ship's abilities and the many states
and behavior of the ice itself to chart a safe course from point A to
point B. Just as importantly, Arne can use his decades long experience
piloting ships in polar conditions to predict in advance and avoid any
hazards that could trap, slow or jeopardize the wellbeing of the ship.
The ship is too far north to have a connection to the internet, so Arne
has arranged for Willem Beekman in the Greenpeace office in Washington,
DC to download and then send via email daily weather charts from the
Canadian weather service. (You can see the site at
http://www.weatheroffice.gc.ca/marine/index_e.html) The charts cover
North America and Greenland, with curved lines and circles called
isobars that show equal lines of barometric pressure across the region.
Isobars outline high and low pressure systems, which in turn generate
wind and weather. Wind and weather affect not only the sea ice, they are
also major forces in the impending break up of the Robeson Channel ice
bridge at 82 degrees north that we visited on June 29, as well as the
disintegration of the Petermann Glacier floating ice tongue that we are
here to document. Arne can look at the daily weather charts, and along
with satellite imagery that he's also having sent to the ship, get a
sense for when the ice bridge will break and the glacier will disintegrate.
The information on the Canadian weather service charts comes from
sources around the world. Since leaving Amsterdam on June 12, the Arctic
Sunrise has been uploading weather information every six hours to the
Dutch meteorological service. The information we provide is then fed
into a computer network, which connects all major weather service
agencies around the world.
At any rate, Arne clicked to open today's Canadian weather service chart
and noticed that the weather information the Arctic Sunrise is providing
appears on the chart. Our little dot on the Canadian weather service
chart is identified as "PE6851". Why is this cool? Well, without us the
information would not be on the charts. This is such a remote place,
it's unique to have a ship here at this time of year providing data. And
given ice records for Nares Strait only go back 32 years, having a
handle on the ice and weather conditions in this area is a fairly new
occurrence. Last, and perhaps this is completely juvenile, I always get
a charge out of looking at a map and pinpointing our location. Given our
chances were 50/50 of even reaching this place, I was trying to temper
my optimism in case ice blocked our way.
In keeping with the luck we've had so far with weather, wind and ice,
Arne's report from today's ice chart is good – no dramatic weather in
our near future. That's a good thing given all of the scientific work
Dr. Jason Box and his team have planned for Petermann Glacier and the
fjord it drains into.
