About
Summary: The plan for this cruise is Project: Island Impact, Area Southern Antarctic Circumpolar Current research, two helicopters onboard, daily weather balloons. Departs from and returns to Cape Town, calls at Port Stanley mid-November.
Goals: Some of the highest concentrations of phytoplankton in the Southern Ocean occur in proximity and downstream of South Georgia. These substantial algal blooms require a significant iron (Fe) source for their development. The objective of this cruise is to understand the sources and pathways of input of Fe and other nutrients (both macronutrients and trace metals) into South Georgia Island shelf waters and further downstream in the Southern Antarctic Circumpolar Current (ACC).We will, therefore, investigate the main Island-derived (shelf) sources of Fe, nutrients and other trace metals including the impact of injection of these compounds by methane bubble ebullition and groundwater seepage. Seeps, groundwater, runoff and sediments may all play a role here.
For this summer generally, Germany is cooperating for logistics support of Finnish, Swedish and South African NAPs, and logistics collaboration with Norwegian, Japanese (tbc), Belgium (tbc) NAPs
