"The weather was not at its best last night! It was cloudy and at times it rained very heavily. Amazingly, these conditions always happen to be when we get a new core on deck and have to cut it into sections! Rain brings a lot of birds too, and this morning a little Chiff Chaff came in the lab and was flying from wire to wire and from one laptop to another, banging its head all over the place. Five of us were trying to catch it but all the time it kept getting away from us. In the end Andrey managed to get it and we put it in another box as The Shoebox was already taken by bigger birds and we were afraid he might get beten up! In the early afternoon we had a science meeting to sum up what we’ve done so far, what results we’re getting and what we will be doing in the next few days. There are very nice stories coming out of this data - these will keep a lot of people busy in the coming months!"

"As Aggie mentioned, a combination of east winds over Iberia and heavy rain in our work area meant that lots of migrant birds on their journey south were drifted out to sea and then grounded on the ship last night. It was quite a surreal experience walking around with a torch in the torrential rain and seeing herons and other birds perched on various parts of the ship. A Cattle Egret, a Night Heron and two Grey Herons were amongst the larger birds seen, and at least 30 or so smaller land birds were seen on or around the ship. Plenty of good photo opportunities!"

 

Left: Christine and Sünje taking samples for X-ray analysis. The samples are 1cm thick slices that are cut from the core. The X-ray analysis is useful as it reveals structures of the sediments that are often hidden to the naked eye. Sünje will be studying the X-ray results as part of her student project, and will be looking for features such as current ripples and worm burrows in the sediment deposits

This afternoon’s science meeting

This White Wagtail flew into the lab and needed to be ‘escorted’ outside. It was later fed some breadcrumbs to help it get through the next stage of its journey.
