Biotic and abiotic data from the baseline study in 2024 and early impact in 2025 for the Princess Elisabeth Energy Island.

This dataset presents findings from an environmental impact assessment conducted along three gradients extending northeastward, southeastward, and southwestward from the Princess Elisabeth Energy Island. Samples were collected at 20 locations in 2024, and 8 locations in 2025 in triplicate, using a 0.1 m² Van Veen Grab, assessing sediment grain size distribution and total organic carbon content. Macrobenthos samples were preserved, stained, and analyzed in the laboratory.
