Conducting operational hydrological environment surveys and research in the Arctic Ocean, acquiring basic environmental information such as marine hydrology and meteorology in this region, obtaining key information on marine environment and resources, and clarifying the current status and changing trends of the Arctic Ocean’s marine environment are of great scientific significance and application value for studies including polar physical oceanography, the response and feedback of polar hydrological environments to global change, and the impacts of polar hydrological environmental changes on biological activities.

This dataset contains marine LADCP observation data from the Chukchi Sea during the 13th Chinese National Arctic Research Expedition (2023). It provides fundamental data for investigating the formation and variability of Arctic Bottom Water, and enables multi-perspective insights into the Arctic Ocean region, as well as the sea-ice-atmosphere interaction processes in the Arctic Ocean and their impacts on marine ecosystems.

1. Measuring Instruments
Instrument Name: Acoustic Doppler Current Profiler (LADCP)

2. Observation Methods and Obtained Data
The observation adopted transect surveys for physical oceanographic investigations, including full-profile comprehensive LADCP observations of parameters such as water temperature, salinity, depth, current speed and direction. The transect surveys were carried out from July 26 to August 11, 2023, and a total of 41 LADCP transect stations in the Chukchi Sea were completed.

3. Observation Area
Chukchi Sea region.
