Abstract. The paper presents the preliminary results of studies conducted in 2024 on the Near-Laptev Sea segment of the Gakkel Ridge from the board of the ORV "Yantar". New data has been obtained on the bottom topography, the distribution of bottom rock material, the structure of areas where focused hydrocarbon fluids discharge are discovered, as well as on individual morphostructural zones in the area. It is believed that the studied segment of the Gakkel ridge may represent a significant province for active gas emission. Keywords: Gakkel ridge, Laptev Sea, mud volcanoes, pockmarks, authigenic carbonates, ikaite, methane, neo-pentane
