Scientists from the US, Norway, Russia, Germany, Italy and China are participating in a study examining the potential role of black carbon, or soot, on the rapidly changing Arctic climate. The Arctic climate is changing faster than some scientists expected. For the first time, a PMEL black carbon sensor will also be aboard the Mantas.
