Greetings from 70S

We are finally here – in the middle of the Weddell Sea! The eternal
quarantine is over, the long flight across the Atlantic is behind us and
all 92 of us have boarded the ice breaker Polarstern without bringing
any Corona-viruses with us! No more masks, no more tests, no need for
social distancing… it actually felt quite strange to go back to
“normal”!

We had a tough start heading out in the Drake passage from the Falkland
Islands a week ago – straight into the famous furious fifties and the
screaming sixties… I was far from the only one who did not show up for
dinner the first night at sea! but we are now steaming southeastward
across a relatively flat Weddell Sea, and the waves and the sea sickness
is easily forgotten when enjoying the view outside the window. Majestic
iceberg scattered around the horizon, sea birds flying along the side of
the ship – and if you stay outside long enough you are likely to spot a
whale or two break the surface.

We are not here to enjoy the view though – and there is hectic activity
downstairs in the labs to get everything up and running before we reach
the southern Weddell Sea and the Filchner Trough where the majority of
our work is to be carried out. Equipment is being tested and installed,
labs are being built, batteries are changed and instruments are
programmed.

The CTD with its 24 bottles are going down for the first time at the test station.

Yesterday the ship stopped for a “test station”, so that everyone who
wanted to could try out their equipment. There where quite some
technical hiccups – but luckily there is still a couple of days to sort
them out before the real work begins!

The CTD-data are displayed in real-time as the CTD descends towards the bottom at the test station – and the oceanographers are watching the first profile with great interest . We quickly realized that the sensor for fluorescence and the flash from the instrument that photographs particles in the water were interfering, so they have to be moved further a part before the next cast.
