If you have
a question about the Project, the Animals, our Daily life here or anything
else relating to Antarctica, then send me an email and I
will do my best to get you an answer. If it seems like a questions others
might be interested in too, I will place the question and answer here on
this page. |
| Q: Will you see
any of the same seals you saw last year?
A: Yes
absolutely. Many of the seals come back to the same colonies every year. The
pups that were born last year will not be back though. They have gone out in
the pack ice where they will spend the next 5-6 years. Not much is known
about this phase of their lives, but after 5-6 years they will return to the
colonies where the females will give birth to their own first pup. |

| Q: What happens if
you get caught in bad weather when you are out on the ice?
A: Though the
weather can change from nice to nasty within minutes, most of the time we
will have seen it coming and are already heading back to camp before it gets bad. At camp
we have everything we need and can just sit tight until it clears, even if
it takes a few days. |

| Q: How do you go
to the bathroom when it is -50F? A: Very very fast! ;-) Well on a more serious note ... we have an outhouse at camp. The seat in there is cut from a piece of blue foam and it is actually reasonably comfortable to sit on. The biggest problem is getting in and out of the 6x6 foot outhouse when the wind is really blowing. The door has a strap that keeps it from slamming into the structure but it is not strong enough. To fix that we tie a 5000lb Cargo Strap around the entire outhouse, but that makes it difficult to get in or out.
There have been times when people have gotten stuck
out there and have simply had to wait for the weather to clear before
they could get back to the kitchen or sleep hut again. |

| Q: Now that B15,
the giant iceberg that blocked McMurdo Sound for a couple of years, has
moved up the mainland coast, will there be a change in the number of seals
in the colonies this season? A: B15 had a severe influence on the ice conditions in the sound. Because of B15 the sea ice did not break up as it usually does during the Antarctic summer. This again meant that the distance from the open water to the colonies was substantially longer than usual, in some areas up to 100 miles. According to Dr. Bob Garrett, it is believed that the ice conditions are directly linked to the seals behavioral pattern and it is therefore expected that more animals will show up in the colonies this year. As Dr Garrott put it: "The dramatic change we expect to see is basically a return to normal conditions!". "In a normal year, as many as 450 to 500 pups are being born in the study area around Ross Island". Last season we saw only about half that number of pups. The Weddell seal can stay under water for 60 minutes or more and can travel substantial distances in that time, especially when doing exploratory dives where they swim near the surface. However, they need to find cracks or other openings in the ice to get air and if the chances of finding such openings are limited, the seals most likely will not attempt to get to the colonies. Dr. Garrott also remarks that "While the ice seems to have broken up all the way in to the north side of Tent island and Inaccessible island last summer, the ice conditions at Turks Head and Hutton Cliffs is possibly even worse than previous years".
B15 also had significant impact on the Emperor and
Adelie penguin colonies around Ross Island. |
