POL scientists Philip Woodworth and David Pugh are in the Falklands for the next few weeks to try to
determine whether sea level is rising as fast in the southern hemisphere as
in the north, and if the land of the islands is uplifting, as some
geological models suggest. They travelled via Santiago and Punta Arenas in
Chile, taking almost 3 days to get there. This project requires a lot of tide
gauge and GPS equipment which is put together by POL's Ocean Engineering and Technology Group (OETG).
The OETG designs, builds and uses instruments which record physical data anywhere from the surface to depths of about 6km and are crucial to the work
POL undertakes.
Philip and David are going to write a diary of their work in the Falkland Islands which will provide an insight into the work and projects POL undertakes and
the challenges and difficulties encounted when working in the field and in remote places.

Well, this was Friday 13 which started off with a driving rain. We went to Cape Pembroke Lighthouse where we had deployed one of our temporary tide gauges for seiche studies a few days before, when the small cove near to the lighthouse called The Gulch in which we had put the instrument was as calm as a mill pond (see photo). However, today when we went to recover it there were enormous breakers bursting into the cove which made recovery impossible. So, we went instead and recovered the last of our temporary installations at the Murrell River north of Stanley. Meanwhile, the tide had fallen and the waves were not as large, so we went back to the lighthouse for a second attempt. We were able to reach the rope to which the gauge was attached but unfortunately it became clear that the gauge was snagged on something. With a lot of effort with various ropes and with some danger in clambering over rocks so as to pull on the ropes from different directions (risk assessments again forgotten) we were able to tug the gauge free. What joy! However, that was short lived as it became clear that its O-ring had failed and its electronics had been flooded with sea water - the first time that has happened with this sort of tide gauge in our experience. That damage may have been caused by the earlier wave conditions. It is possible that the data in the memory can be recovered somehow but that remains to be seen. In the afternoon we completed packing our wooden crates for their return to POL on board the Shackleton at the end of April. A well deserved dinner at the Stanley Brasserie followed.
Tomorrow, we leave Stanley with much regret as we have met a large number of charming and helpful people. A large fraction of Stanley got to recognise us as the 'tides men' thanks to our article in Penguin News, an interview on Falklands Radio and a well-attended evening public lecture. Our main project, the sea level measurements at Port Stanley and Port Louis, would have been impossible without their help and also without the mostly fine weather we have had. That project looks set to have some very interesting results. Our sideline project into seiches was also successful in spite of minor setbacks as mentioned above, and may be taken further forward in the future with the help of people we have met.
This ends our Falklands diary as tomorrow Phil flies to Santiago in Chile for an eventual return to Liverpool, while David has one day in Punta Arenas prior to travelling back to the UK the wrong way. He will have a stopover in New Zealand to see old friends, and in Hobart and Melbourne

This morning we spent partly at FIPASS where we downloaded the contents of the data logger of the older of the two POL pressure gauges there. Other events included organising the sending of some of our stuff back to POL air-freight, and a few holes of golf at the Stanley golf course. In the evening we gave a public lecture on 'Sea level changes in the Falklands' to over 20 people at the Stanley High School.

day saw us drive out to Port Louis for the last time to recever our equipment. The morning started with torrential rain and fog but then cleared into another fine day. The equipment included Peter Foden's 'tide gauge in a suitcase' and two of David's RBR temporary gauges, plus the GPS equipment near to the Ross marker. The Land Rover was packed full on return. The rest of the day was spent saying thank yous to various people, including the landowners Peter and Melanie Gilding at Port Louis and Mr and Mrs Jock McVie and their daughter Trudi at Brookfield Farm, and also to George and Jenny Patterson-Smith at Port Louis. Preparations are under way for an upcoming visit by Princess Anne to Port Louis, however it is likely she will be more interested in the horses than tides. Refreshments in the Stanley Arms followed.

Today felt very different in Stanley with no tourists at all, after the 5000 ashore from cruise ships yesterday. We visited the Fitzroy settlement on the east coast of East Falkland with the intention of deploying one of our temporary tide gauges for our seiche investigations. However, although the weather was warm, there was too much wind to safely deploy it. Instead, we installed it in the Wurrell River which is a tidal arm of Port William, which is in turn the outer part of Port Stanley harbour. When analysed in combination with data from the Pembroke Lightouse temporary tide gauge installed yesterday, we may be able to understand better what drives the seiches of this part of the coast. Both of these gauges will have to be recovered late on Friday, shortly before our last week here ends. Otherwise we listened to the transmission of our Radio Falkland interview, recorded yesterday, and worked on our public lecture to be held on Thursday evening. We decided that we did have time to play a round of golf this time - that pleasure will have to wait till our next visit. Tomorrow will be one of our busiest days when we recover all of our equipment from Port Louis so we are hoping for good weather again.

Today we moved all of the equipment that we no longer need from a workroom near to the Public Works Department in Stanley into boxes at the FIPASS terminal prior to our return home. We then visited the Stanley Museum in order to obtain the key for the Cape Pembroke Lighthouse which is located a few miles east of Stanley. We were able to deploy one of David's temporary tide gauges near to the lighthouse, with the intention of removing it at the end of week, so as to obtain more information on seiches in the waters near to Stanley. The lighthouse is an interesting one, being constructed out of cast iron instead of stone blocks as in the UK. It is in rather better condition than even the Bidston lighthouse, for example, with spectacular views from its balcony. In the afternoon we recorded an interview for Falklands Radio on our work during the last few weeks.

Today we took a long drive around the recently-opened circle of new
road that connects Stanley with Goose Green in the south of east
Falkland, San Carlos and Port San Carlos in the west, and Teal Inlet
and Estancia in the north. We covered 160 miles over still rough roads
in our antique red Land Rover (see photo below). It was a beautiful day amidst
outstanding scenery - not a person (or even a sheep) for mile after
mile.
On the way to Goose Green we spotted the Endurance, which has to
return to the UK for a complete engine refit, piggy-back on the
enormous Dutch transporter called the Target (see photo below). Two engineers from the
Target had stayed at our Guest House for the previous couple of days.
In Goose Green we recovered the temporary tide gauge that Phil
deployed last Wednesday (see photo below). This was covered in a thick sludge which
hopefully will not have blocked the pressure sensor. The data should
give us insight into seiches in Choiseul Sound and some idea of the
local tidal characteristics. The tea shop was open as usual and was
full of army personnel on Sunday outings. We then turned into tourists
taking in the San Carlos British cemetery and museum where Lt. Col. H. Jones, VC is buried (see photo below). Shortly after
that, we turned into geologists, obtaining samples of peats from
exposed sections at San Carlos, Teal Inlet and Estancia, following
instructions from Andy Plater in Liverpool Geography (see photo below). Tomorrow almost
5000 tourists from cruise ships are expected in Stanley, more than
twice the local population - fortunately for them the gun at the
Narrows no longer works (see photo below). We expect to spend part of tomorrow making
preparations for sending our equipment back to the UK on either the
Shackleton or James Clark Ross.

Here is a report from David's trip for 2 days on Saunder's Island, the location of the first British settlement in the Falklands, and one night on Carcass Island, so named after HMS Carcass which surveyed the island in 1766. Various wildlife spotted included a Gentoo penguin singing the praises of POL science (see photo below), Magellanic penguins, some of these can also be found at Gypsy Cove near to Stanley (see photo below), the Striated Caracara one of the world's rarest birds of prey (see photo below), a Black-Crowned Night Heron (see photo below), and fighting Elephant Seals (see photo below). All of these were taken on Carcass Island. Today has been largely a day off for us in Stanley, which has been inundated by thousands of tourists from a cruise ship. Work resumes tomorrow with more levelling and tide-pole reading at Port Louis, weather permitting.
