| Changing
landscape
Icebergs frozen in the first year ice change
the landscape known from previous years. |

|
| At the end of
last summer (Jan-Feb 2007), the sea ice had broken up all the way in past
the Delbridge islands. This is not unusual at all, however, the last few
years this has not happened because of the gigantic iceberg, B15, which
blocked the entrance to McMurdo Sound and thereby prevented the ice from
being broken up and blown out to sea. When the sea ice finally did break up
last summer, icebergs drifted into McMurdo Sound and changed the view from
the B009 field camp. The bergs are now stuck in the first year ice and will
stay here until the ice breaks up again, possibly this coming summer. If that happens, the landscape will change yet again. |

| "Pupping" season
The pups are coming fast now. |

|
| It might
be a record year if this keeps going on! We are in the middle of the pupping
period for the McMurdo Sound Weddell seal population and they are coming
fast. We have several times been working with an animal in a colony and when
turning around, found that another pup was just born a few feet away minutes
earlier. Yesterday alone we tagged over 70 new pups, which brought us up to over 250 pups this year so far. Comparing this to last year, on the same date, we had about 130 pups. In 2004, a year strongly influenced by the B15 iceberg blocking the sound, there were only about 35 pups at this time. The weather has been all over the map, as
can be expected in this part of the world. One day we will have clear skies,
mild temperatures (all things being relative) and no wind. The next day we
might have thick cloud cover, low temperatures and very high winds. Our
little weather station, in the kitchen hut, registered 74Mph winds a week or
so ago and the temperatures, including the wind chill factor, is often in
the -50F range or worse. |

| Field season
started with a weather day
We have now been in camp at Big Razorback for
a few days and the field season has finally started .. but .. the weather
has been interesting! |

|
| Second day,
Thursday, in camp was a weather day and half of today, Sunday, ended up as a
weather day as well. Today started out with high winds in the morning, but
good visibility. We checked with MAC Weather, the weather people on station,
and the prediction was "Nice weather and good visibility for the next 48
hours". I suppose Good Visibility is a relatively loose term, and today
it apparently meant something like 5 to 10 feet.
Jen and Adam went to Hutton Cliffs, and the
rest of us went to Turks Head with the weigh sled to weigh the few new moms
there. Around 2pm, we drove the snow machines in among the pressure ridges
to have lunch out of the wind. During the next 10 minutes, the wind picked
up and the snow started flying so by 2:30, visibility was basically gone.
Since we had already flagged the route between the Razorbacks and Turks
Head, there were no concerns finding our way back to camp, but it was one of
those rides where you constantly wonder if the next flag is going to show up
in front of you or not. Jen, Adam and Sasha took the Pisten Bully
to town to get showered and to pick up some supplies. The rest of us put
some fish on the grill behind the kitchen hut and had a nice dinner. The
grill has to be tied to the hut with a 5,000 lb cargo strap to ensure the
dinner stays close to camp. Most things are a little different in
Antarctica than back home! |

| Leaving McMurdo
Wednesday afternoon we finally got our snow
machines and were able to get out of town. |

midnight. |
|
| The camp got
pulled out Tuesday evening and it got positioned and established Thursday.
With everything but communications (telephone and internet connection) taken
care of, we were able to finally get out of McMurdo and move in at the camp
site close to Big Razorback Island, Wednesday evening. To get some pictures of McMurdo I climbed Observation Hill, also known as Ob Hill, outside of McMurdo Tuesday night. From the top you can see all of McMurdo, see the New Zealand research station, Scott Base, and see the Delbridge islands which is where you find Big Razorback Island where camp now is set up. Primary purpose of the hike was to see McMurdo in night light, something which is not going to be possible next time I get to town.
We are ready to get out of town and get to
camp! While it is nice to have thing like showers, the store, video rental
etc in town, we all much prefer to be in camp and away from McMurdo. We will
go back in after 2-3 weeks, but will then only stay a night or perhaps only
a few hours. After that, we are ready to get back in the field again. |

| Preparing for
setting up camp Setting up the field
camp requires a large amount of equipment. The first few days are spent
getting this done. |
|

Night time in McMurdo early in the season. It
is around midnight, but soon the sun will be on the sky 24 hours a day. |
|
| In preparation
for the season, all the required equipment has already been requested from
the Science Support depots in McMurdo. When we arrive, all these items are
pulled from the depots and delivered to us, or made ready for pickup at
different locations in McMurdo. The first few days on station are spent
going through safety refresher trainings for those who have been there
before, or more comprehensive trainings for the new people. While the new
people go through training, the "old hands" spend their time getting the
equipment issued. An important stop is the food room where we get all the
food supplies |

| Deployment to the
Ice We arrived at McMurdo station
last Wednesday, as planned. It is not uncommon that the flight get turned
around because of bad weather at McMurdo, but we were lucky once again, and
made it down in the first try. |

transport plane on the way into the Ross Sea area. |
|
| The flight from
Christchurch to McMurdo station is on a C-17 military transport run by the
United States Air National Guard. Checking in for the flight is just like
any other flight with passport, boarding pass and weighing of your
luggage. One difference is that after the check-in-luggage is weighed, the
passenger will step on the scale too, carrying all carry-on luggage. Configuration of the aircraft differs depending on what cargo they might have to carry, but it is generally a combination of regular seat rows as found on commercial aircraft and jump seats along the side of the aircraft. The flight is fairly noisy, so with most people wearing earplugs, it is basically impossible to have a conversation with anybody. The 5 1/2 hour flight is therefore typically spent reading, sleeping, or just waiting. For a lot of people, this is a process
they have gone through several, if not many, times over the years, as many
people come back to the ice year after year. But for some, this is the first
time going to the Antarctic continent and the expectations of the adventure
is detectable in their questions or by simply observing their facial
expressions. This year we arrived in beautiful calm weather and the first
impression of the coming season on the ice is a very positive one. Later,
the true nature of the continent will become obvious to anyone who will be
working outdoors. |

| New Zealand
Made it to Christchurch / New Zealand.
Tomorrow we get our Antarctic clothing issued and then, weather permitting,
we will be flying down to the ice on Wednesday |
|
| Wednesday September 26th, 2007 | |
|
The journey is about to begin
Only a few days left till the plane leaves
from Atlanta heading to Los Angeles via Dallas. There I will meet the rest of
the team and the 6 of us will travel together to Christchurch / New Zealand.
Once there, we wait for the military airlift to be cleared and then it is on to
McMurdo station in Antarctica. It could be a couple of days, which will be spent
getting the cold weather clothing issued and maybe doing a little sightseeing. |
