Satellite View Captures Ring of Phytoplankton Around Chatham Islands
NASA's Earth Observatory captured a vibrant ring of phytoplankton encircling the remote Chatham Islands in January 2026, observed by the VIIRS instrument on NOAA-20. The bloom forms where cold, nutrient-rich Antarctic waters meet warmer subtropical waters around the Chatham Rise, supporting local fisheries and marine life, though the region is also known for whale and dolphin strandings.
