Abstract:
Previous Sternfahrten were mainly conducted in spring and summer. To cover the seasonal aspects more thoroughly, including a winter situation, this cruise was conducted in late autumn (20 -22 November 2025 ). We used the RV Heincke (cruise HE673/2) instead of the RV Uthörn. The Heincke's draught is greater, so we could not reach all of our previous stations. Surface and bottom water samples were taken with a rosette.
