PS101 - Weeklý Report No. 1 | 10 - 18 September 2016


[19. September 2016] 

The aim of POLARSTERN expedition PS101 is to study the geophysical, geological, geochemical and biological processes at seamounts and sources of hydrothermalism at Gakkel Ridge of the Central Arctic. Such integrated studies of ultraslow oceanic spreading zones are rare, because the most extensive of these systems<ins></ins>, the Arctic Gakkel Ridge and the Southwest Indian Ridge, lie in poorly accessible areas.
