Cruise narrative
Sunday 18. March
Loading of equipment in Longyearbyen at Nykaia around 10:30. Arrial for
dinner at 16:30.
Departure around 20:00 with some open water tests in Isfjorden.
Monday 19. March
Mounting of new flux-meter at the ships bow, ready after lunch. First
tests inside of Axel Øya in Van Miijen fjorden.
Logging as we steam east, ice edge well inside of Axel Øya. CTD
mounting and testing.
Setup of Helohut, had to be modified. Test RDCP.
Stop in position 77 50.167 N and 16 32.307 E for beam test for SINTEF.
Sea ice sample, and deployment of GFI flux meter on the ice at 23:30
overnight.
Tuesday 20. March
Collected GFI Flux from the ice, steaming east to Svea to do ice
navigation tests for DNV.
Request to break ice for 'Green Frost' is accepted and we have to wait
1 day. Decides to make an
ice station in Van Miijenfjorden. 77 48.552 N and 15 56.999 E.
Deployment of Helohut, turbulent clusters,
RDCP and MSS. Also GFI Flux meter.
Wednesday 21. March
Depart from ice station at 01:30 to meet 'Green Frost'. Breaking ice
and removing ice from the dock in Svea.
Back to ice station at 11:30 to recover instruments and people. Flushed
instruments and stoved for going south
around Sørkapp. Attempts on having open water tests for SINTEF, too
much waves. Drifting bouy, not possible to
recover. RDCP data chekcked and OK.
Thursday 22. March
Very thin ice in Storfjorden. The DNV EM-instrument readings says 5-20
cm ice thickness nearly all the way north.
Steaming at 10-13 knots. CTD and GFI Flux station at Storfjorden sill
at 150 m depth. Engine trouble, drifting for
2-3 hours, thus late arrival et Freemansundet ice station. Deployment
while night falls. -1 deg C, Strong winds, 15-20 ms/s. Snowdrift.
50 cm ice thickness on fast ice. Freeboard -1 cm (water level 1 cm
above on snow). Lots of sluch below ice.
MSS sensor faults, TIC's and RDCP are fine, strong currents, 90 cm/s.
Friday 23. March
Departure from ice station, leaving TIC's, Miles, Johan and a ship
officer as polar bear guard. A female bear with two cubs.
Profiling south westward with MSS and CTD, and UNIS flux meter. One
meteological balloon profile. Profile mast of Aanderaa
instruments from the ships crane. Got to about 40 m depth, takes time
to run three instruments at each station.
Some sea ice/grease ice samples taken. Return to ice station as dusk
falls. Decides to recover all instruments apart from RDCP.
Strong winds now, 25 m/s. 3 bears. Starts longer profile out towards
deepest part of Storfjorden.
Saturday 24. March
Got to 140 m depth during the night, logging only with UNIS Flux meter,
and then using CTD and MSS as we steam back
towards Freemansundet. About 20 cm ice thickness here still, up to 1 m
thick in places, increasing in thickness as we aproach
Freemansundet. Barbeque on Helideck, Rugby match. Recover RDCP at 23:00.
Sunday 25. March
Beam-test by SINTEF and ice naviagtion, but could not get through
Freemansundet as planned. A 7 m thick ridge stopped eastward
progression effectively. Photography on ice. Talk about our
activity in the OPS room. CTD + MSS station in the deepest location
of Storfjorden. Then profiles across the outflow with high resolution
500 m. Almost no ice here. Fairly big waves. About 250 m drift
at each station.
Monday 26. March
3 MSS stations, then impossible to use MSS as KV Svalbard needs speed
(about 4 knots) to remain normal on the
wave direction, and the ship rolls extensively when it is paralell to
the wavecrests. Very little ice around Hopen
on the sattelite SAR images. Decide to make an ice staion east of Edge
Øya. Steaming north in a polynya created
by the strong winds from south west. 3 project leaders on the
bridge between 23 and 24 finally makes a stop in fairly
thick ice after alot of discussions, we stop the ship by a 1500 m big
floe.
Tuesday 27. March
Test drilling shows 40-60 cm ice thickness, so we make the last station
here. Quiet conditions now, and we are
done before lunch. Quiet in the ocean as well, low currents. A
warm layer, but deep down at 120 m depth.
Sea ice measurements, and ice cores. KV Svalbard stayes by the
camp. - 6 deg C and little wind during the
night, and we make shifts to work through the night.
Wednesday 28. March
Recover ice station after breakfast, has worked well, but too exiting
data. Packing and cleaning of equipment,
stowing away. DNV + SINTEF has their last ice navigation tests. Only
slush/frazil around Hopen when we pass
so it would not have been possible to have an ice staioin here.
Thursday 29. March
Inspection of Russian vessel north of Bjørn Øya. And a visit to the
station ! They serve coffee, have a tour, and the brave
among us becames members of the swimming club. Interview on NRK 1
'Kveldsåpent'.
Friday 30. March
Group discussions on what we have achieved, start writing a popular
story for Bjerknes Times.
Exchange of notes and images.
Saturday 31. March
Arrival Tromsø at 08:00
