On July 2, the Arctic survey boat (ASB) was lowered by crane from the Healy for science excursions away from the main ship, which can mix water and cast a shadow that interferes with the scientific measurements. ICESCAPE scientists and Coast Guard crew made first-of-a-kind measurements near the edge of Arctic sea ice collecting water samples from the Chukchi Sea. The samples are returned to scientists in the Healy's laboratory for use in biology and chemistry experiments. (Photo by Kathryn Hansen)
