The North Sea. It has quite a reputation. I packed sea
sickness medication when I got ready for the cruise. We’ve been in the North
Sea since July the 16th, but we haven’t seen much other than
mirror-like seas. Sometimes the wind picked up at the end of our shift, and we got
rocked to sleep nicely, but then all was calm again by the time we got back to
work, and the coring was never threatened. So far it’s been a doddle! Will it
stay that way? Hold that thought!
The times have changed since we got to Transect 2. As the
distances here are larger, there are more periods with nothing to do other than
stare at geophysics. That leaves me time to start on my processing. So I have
washed and photographed all my 14C samples, I have labelled all the photos, I
have made a list with what kind of sample they are and what sedimentary units
they are from, I have made a list of in what sort of sections the cores have
been cut (in the beginning, documentation of such was a bit sloppy) and
corrected all the pictures with wrong labels, and I have done the editing of
the pictures that were forgotten the first time around. I have made a list of
all our cores, and information on where and when they were taken, how long they
are, how much I like the sediment and more such things. I made maps of where
the good cores are and from which ones we have a 14C sample. There is still more
to do but it’s good to see so much tedious work being out of the way even
before we’ve stopped coring! The only thing is that even though the days are
less busy with coring and core splitting, I am more tired than I was before.
But it’s worth it! No need to do all this tedious inventory work in the office!
The work goes on: taking the core catcher out of the core liner once it's on deck
Making boxes for the cores sections to be stored in
So does anything become apparent doing all this work? Yes!
We have 58 radiocarbon samples, which isn’t bad, and some of them are beauties.
We don’t have as much good data from the Minch as we had hoped, as we had to
make do without the vibrocorer for several days, and once it worked again we
hit a few duds, but we have enough to work with. The other areas all have
yielded nice cores, and the area around Shetland has proven to be the richest
ground for 14C samples. Funnily enough, the best cores we took were from north
of Cape Wrath (see also the blog post one of the cores got on its own), which
was an area we hadn’t initially planned to core. I had just seen, during my
visits to the BGS, that they had cored up some nice materials there, and we
bolted on a little transect to see if we could too. And we clearly did!
Sometimes things you can date using radiocarbon do rather stand out in a core
So what about this North Sea, is it going to stay a
millpond? Probably not! As I write this, the southern North Sea (we are still
quite far up North, above Newcastle) seems to be a boiling churning inferno,
while we are still steaming though dead calm waters. We only have just over a
week to go; will the tail end of the cruise be curtailed by bad weather? Stay
tuned!
