A person prepares tools to gather data at the Ny-Ålesund research station, which is on the Norwegian island of Svalbard close to the North Pole. Photographer Anna Filipova spent a month at the station, where scientists are measuring environmental conditions to learn more about climate change.
Researchers from 11 countries live in Ny-Ålesund, a former coal-mining town.
The Zeppelin observatory is on Zeppelin Mountain -- an undisturbed Arctic environment away from major pollution sources.

Filipova had to be quick in grabbing these images. To photograph one particular atmospheric sensor, she only had one minute, because of concerns her breath would alter the instrument's readings.
Filipova's images are purposefully monochromatic. The photographer wanted to highlight the isolation she felt.

This is a place where, according to the scientists Filipova met, the air is "the cleanest air you will breathe."

This research tower, near the Ny-Ålesund settlement, gathers meteorological data for scientists.
"There are 15 people at the settlement, but most of the time you don't see anybody," Filipova said.
