PACE was launched on February 8, 2024, and the first OCI global map of ocean chlorophyll was produced on March 4, 2024.\r\n\r\nThis year-long visualization of PACE chlorophyll data uses a traditional rainbow color palette to show areas with high chlorophyll concentration in red and yellow, medium chlorophyll in green and low chloroiphyll in blue and purple. Each individual image is a 30 day average, and the visualization covers one year, from March 2024 to March 2025, revealing the seasonal cycle of phytoplankton activity.",
