题目：the treetop research
What is the TreeTop Barbie project?
TreeTop Barbie was designed to inspire youth - especially young girls - to become aware of the field of the forest canopy. She is a real Barbie doll, but wears hand-tailored clothes that are modeled on real field clothes and climbing gear, including a field guide to canopy plants and animals (both Barbie- and human-sized). The TreeTop Barbie package includes the doll and a personal letter from Barbie about forests and their importance to people.
What issues does this project address?
TreeTop Barbie can serve as a role model to encourage young girls in directions that are alternatives to the mainstream Barbie doll and what she represents in our society. TreeTop Barbie and her accompanying educational materials also provide a link between youth and an exciting part of the natural world in tropical and temperate ecosystems.
How can I get a TreeTop Barbie?
TreeTop Barbie is distributed by The International Canopy Network (ICAN)? a not-for-profit organization dedicated to promoting forest canopy conservation through research and education. Funds generated will support this and other outreach activities. Exploration of forest canopies is no easy task—since researchers can't cross between tree-tops? they have to clamber up trunks, explore, descend, and then climb the next. Or they did, until the advent of the Sol Vin Bretzel Canopy Raft.
A canopy raft is, basically, an inflatable PVC pontoon frame with high-tension netting spread between. They're pre-inflated and lifted into positioned via airship, dirigible, or helicopter. Once in position, the rafts are set down among the tree-tops, allowing researchers unfettered access to the uppermost reaches of the forest ecosystem. Scientists can observe from the raft? rappel from it too—they can even live on its temporary floor for several days at a time.
The pretzel shape of the raft in the top image is known as a Sol Vin Bretzel, created by architect Gilles Ebersolt (yes，like "Pretzel" but in German)，a recent design that replaced the previous, octagonal raft shape. Its unique 400m2 area offers numerous advantages over its predecessors. Itrs a more structurally sound platform that maximizes surface area, preventing any outlying section from folding or collapsing. It‘s also extremely lightweight——meaning it doesn't crush the new growth of the canopy upon which it rests.
