In winter, he spends the night high in its branches to study hibernation; in summer, he collects wildlife samples to study the tree's own particular ecosystem.
Though Messenger was able to detect the abundance of individual elements on Mercury's surface - including iron, titanium, sulphur and potassium - without rock samples to study, scientists cannot determine the exact compounds or minerals in which those elements are arranged.
De Rothschild will collect water samples to study and, using a satellite phone, post photographs and video clips on the Web site of Adventure Ecology, an environmental organization that he founded.
We are taken through the stages: Lorius's first trip to Antarctica to study snow; the realisation that the ratio of "light" hydrogen atoms to "heavy" in each snowflake corresponds precisely to the ambient temperature of the day of the snowfall; then decision to take core samples to study the change in temperature over time.
As the journalist Rebecca Skloot recounted in her 2010 best-seller, "The Immortal Life of Henrietta Lacks," it was not until 1973, when a scientist called to ask for blood samples to study the genes her children had inherited from her, that Ms. Lacks's family learned that their mother's cells were, in effect, scattered across the planet.
The Si samples to study were sorted into two groups.
The present study focused on the technique to provide irradiated samples to study biodosimetry.
Unfortunately, transportation surveys seldom have large enough samples to study each CT within a city.
Cross-sections were prepared from these samples to study the gilding technique.
He said scientists were collecting skin, muscle and baleen samples to study the creatures.
Atomic force microscopy was performed for the pristine and irradiated samples to study the surface morphology.
