  • On July 14, drift ice was sampled at the northernmost point of this cruise, 69°58.3' N, 168°29.3' W. The drift ice came from an area where sea ice was concentrated (visible from the Oshoro-Maru), and had partially drifted away from the area. The sampled drift ice will be melted and examined for various constituents.

    Drift ice sampling scene. The whitish object floating in the upper right of the net in the center of the photo is drift ice. After this photo was taken, the ice was brought on board by the crew's skillful netting. (July 14, 2023; photo by UENO Hiromichi)
