A person silhouetted against a green swirling aurora stands atop a pile of snow and ice, holding up both hands. In the person’s right hand is a rock hammer.
A group of people with instruments are seen from far above, their long shadows extending toward the top left of the image. Around them are various types of terrain, from a dry looking expanse of tan soil with white areas to richer looking reddish soil with green objects that appear to be plants.
A woman in profile leans over a blue railing on a concrete pier. With her left hand, she reaches toward a green plastic bucket of water that she is holding up by an attached thin white rope held in her right hand and loosely wrapped around her arm. Behind her can be seen the back of a boat with the NOAA logo, “R8001,” and “Muskegon, MI” printed on its stern.
