The climate changes taking place on Earth have substantially modified the physical, chemical, and biological properties of the World Ocean, especially evident in polar regions. The Arctic ecosystem is highly sensitive to climate warming, so monitoring processes in the marine environment require appropriate measurement techniques. Information derived from the models based on satellite data is often used as a tool for mapping changes in the marine environment and providing environmental background for in-situ research. They allow us to look at the phenomenon studying on a larger scale. In the current work, we present the results of measurements of pigment concentrations in samples collected on the Greenland shelf in 2021 and 2022, compared with satellite observations. We used values of chlorophylls and carotenoids concentrations to analyze the biodiversity of the polar ecosystem.
