We
are students from the 9th D grade of the "Tudor Vianu" National
High School of Computer Science, Bucharest, Romania. We are honored for
having the opportunity to participate at the LIMA Quest Challenge. In
this way we had the chance to improve our team spirit and find out new
interesting information about Antarctica, which we considered useful.
We
enjoyed
working with you at this project and we appreciated the chat session
very much.
We
hope you will involve us in your future projects and contests.
Thank you very much for inviting us to collaborate with you,
and we hope that you will appreciate our material!
Proposal:
1.The name and/or description of your chosen ice feature
We chose the nunatak as our ice feature. A nunatak is an exposed, often
rocky element of a ridge, mountain, or peak not covered with ice or
snow within (or at the edge of) an ice field or glacier. The term is
typically used in areas where a permanent ice sheet is present.
2.An image of your chosen ice feature
Middle section of Taylor
Glacier with nunatak
3.The location of your selected feature in terms of its longitude
and latitude as well as the region of Antarctica in which it exists.
(Teams are encouraged to include a map of Antarctica with a mark pinpointing
the location of their selected feature).
77.8 °S, 161°E
4.A paragraph explaining why your chosen ice feature is scientifically
interesting.
We consider that the chosen image (Middle section of
Taylor Glacier) is the most interesting because of the spectacular nunatak,
which is surrounded by an ice formation.
The image is rewarding because of the complexity of the forms of relief:
we can observe ice dunes, the mountain peak and other important details
from the picture. The valley determines the direction of the ice flow,
and so illustrating its movement. The ice is surrounding the peak of
the mountain, isolating it, and so revealing a rock saddle.
5.A paragraph hypothesizing what geologic processes you think are
occurring to create this ice feature.
A glacier is a large, slow moving river of ice, formed from compacted
layers of snow that slowly deforms and flows in response to gravity.
The Taylor glacier is an ice feature whose formation corresponds to the
process described above.
The nunatak of Taylor Glacier might have been formed as a result of a
repeated process of ice melting and freezing after it glided across the
surface of the peak it had originally covered.
6.A paragraph asserting why you and your team should be funded to
further investigate this area of Antarctica. (In other words, what
are the potential benefits of exploring this feature?)
Situated at 77.8 °S, 161°E, the Taylor Glacier presents some
interesting formations called nunataks.It is well known that nunataks
represent some areas isolated by the surrounding ice or glaciers, creating
some habitats that can't be found anywhere on Earth. The term is frequently
used in areas where a permanent ice sheet is present. We consider that
if this areas can be studied in detail it would help us for better
understanding of the world and the environment, and might lead to the
discovery of some new species.
