The visualization shows the ICESCAPE ship's path through the Chukchi and Beaufort seas north of Alaska from July 3, 2011 through July 8, 2011. The ship stops and takes measurements along the way. The measurements are taken by canisters lowered to various depths that sample the water. The measurement depths range from 1.8 meters to 149.3 meters below sea level. The sets of measurements are broken into two transects. The first transect is the trip out into the ice. The second transect is the trip back. Topography (above sea level) is exaggerated 10 times. Bathymetry (below sea level) is exaggerated 200 times in order differentiate the measurements.
The colors of the measurements (i.e,. stations) correspond to the color bar below which represent chlorophyll-a concentrations. Measurements that are depicted by spheres were acquired while the ship was in open water while measurements depicted by cubes were acquired when the ship was in ice. As data is collected, a wall of interpolated data is generated.
An important finding of this research was that high concentrations of chlorophyll-a were found under the ice.",

"description": "Scientists have long thought that the waters underneath Arctic sea ice were too dark for plant life to grow. But in summer 2011, a NASA expedition to study the impacts of climate change in the Arctic found massive blooms of phytoplankton, tiny plant-like creatures essential for all sea life, thriving below the floating ice pack just north of Alaska. Researchers suspect changes to the Arctic Ocean's frozen ice cover are behind these blooms. Shallow melt ponds riddle the thinning ice at the edges of the ice cap, acting as natural skylights that allow sunlight to reach the nutrient-rich waters below. These conditions create the perfect breeding ground for phytoplankton. The visualization shows phytoplankton concentrations observed at different depths along the expedition's sampling route in the Chukchi Sea from July 3-8, 2011. || ",

"description": "Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition punched through three-foot thick sea ice to find waters richer in microscopic marine plants, essential to all sea life, than any other ocean region on Earth.The discovery is the result of an oceanographic expedition called ICESCAPE, or Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment. The NASA-sponsored mission explored the seas along Alaska's western and northern coasts onboard a U.S. Coast Guard icebreaker during the summers of 2010 and 2011. The finding reveals a new consequence of the Arctic's warming climate and provides an important clue to understanding the impacts of a changing climate and environment on the Arctic Ocean and its ecology. || ",
