Abstract:
Zooplankton samples were collected by vertical hauls with a NORPAC net (mesh size: 0.33 mm, mouth diameter: 45 cm) during the T/S Oshoro-maru cruise (cruise number: C255) in the southeastern Bering and Chukchi Seas in 2013. Zooplankton samples were preserved with 5% buffered formalin immediately on board. In the land laboratory, the zooplankton samples were measured for wet weight with a precision of 1 mg using an electric balance (Mettler Toledo, New classic MF).
