Cruise Status

completed

Departure

October 14, 2015, Tokyo, Japan

Arrival

November 02, 2015, Nagasaki, Japan

Research Area

East China Sea

Objectives

The objectives of this cruise are: (1) quantify the distribution of trace elements and isotopes in the East China Sea and their fluxes to the western North Pacific, (2) understand the biogeochemical/physical processes, spatial and temporal variations and cycles of nutrients in the East China Sea, and (3) reveal long-term biogeochemical changes in the East China Sea/Kuroshio area.

We expect to draw a full picture of biogeochemical cycling in the East China Sea and its adjacent Kuroshio water, quantify the material transport fluxes from marginal sea to open ocean, and clarify the interaction between this marginal sea and the mid-latitude western North Pacific.

In addition, there were two clean cross stations in GP06 line. RV Dongfanghong2 (Ocean University of China) cruise (19 October-2 November, 2015) covering the inner shelf was conducted led by Jingling Ren. Two cross stations were observed by R/V Hakuho-maru on 27-28 October and R/V Dongfaonghong2 on 26-27 October, 2015.
