PS120 - Weekly Report No. 3 | 17 - 23 June 2019

Working in the Ocean

[24. June 2019] 

It is Sunday today on the POLARSTERN. I was delighted with the crispy croissant and apricot jam, which I consumed for breakfast with a delicious cup of creamy coffee, this morning. Our research doesn´t stop on Sundays. Ship time for ocean research is too precious.

Polarstern, 07°0´N, 23°48´W

[18. June 2019] 

On Friday the 14.06 we arrived at the equator. We stayed put there for a while to measure the different  over depth.  If one stood on the portside of the ship one was in the southern Hemisphere and standing on the starboard side, one was in the northern Hemisphere. The meteorologists could wander between both, outside their office.

Polarstern in Port Stanley

This is set upon RV „Polarstern“ as a collaboration of POGO (Partnership for Observations in the Global Oceans),  NIPPON FOUNDATION and AtlantOS.

The last week at sea

[03. June 2019] 

After our storm on last Friday, the sea only calmed down very slowly and station work was only possible with two CTD stations in the late night towards Saturday. The deployments were made about 60 km to the West of the spreading centre on its flank. There, the seafloor is parted by North-South orientated, parallel faults covered by young sediment, and we discovered both in the sediments as well as in the water column indications for fluid circulation in the Parasound recordings.

The expedition‘s stormy

[27. May 2019] 

The rapid changes in weather condition, which hit us last weekend, was exemplaric for the entire week. While were able to achieve the 450th dive of MARUM ROV QUEST (Fig. 2) on the ridge segment E2 of the East Scotia Ridge on Saturday, the storm on Sunday, which we endured in the ailee of Zavodovski Island, showed us that Antarctic winter has started.
