Summer Ship Tracks in the Pacific August 26, 2018 In August 2018, long, narrow clouds stood out against the backdrop of marine clouds blanketing much of the North Pacific Ocean. Known as ship tracks, the distinctive clouds form when water vapor condenses around the tiny particles emitted by ships in their exhaust. Ship tracks typically form in areas where thin, low-lying stratus and cumulus clouds are present. ... The Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua captured this natural-color image of several ship tracks extending northward on August 26, 2018. The clouds were located about 1,000 kilometers (600 miles) west of the California-Oregon border. Similar environmental conditions also triggered the formation of ship tracks in this part of the Pacific on August 27 and 28.

TOPSHOT - An aerial view of pancake ice and melt on July 19, 2022 as captured on a NASA Gulfstream V plane while on an airborne mission with University of Texas scientists to measure melting Arctic seaice. New observations from ICESAT-2 show remarkable Arctic Sea ice thinning in just three years. Over the past two decades, the Arctic has lost about one-third of its winter sea ice volume, largely due to a decline in sea ice that persists over several years, called multiyear ice, according to a new study. The study also found sea ice is likely thinner than previous estimates. (Photo by Kerem Yücel / AFP) (Photo by KEREM YUCEL/AFP via Getty Images)
