2st July 2014, the day we conquered Scoat Tarn!
Your mission, Fiona Russell, should you wish to accept it is…… compile a group of eight willing volunteers, two boats, paddles, 8 life jackets (must be safe), two corers, 350m of rope, 10 litres of drinking water, a ladder, some dodgy knees, sunshine and some cling film, then tackle one of the highest lakes in the Lake District to recover 1000 years of mud from beneath 18m of water. This message will self-destruct in 30 seconds.
After some last minute alterations due potential 40 kph winds on Thursday, we set off for an epic coring trip to Scoat Tarn, a typical mountain cirque basin at 600m altitude in the Lake District National Park, UK. Scoat Tarn is small (5.2ha), deep (<20 m), lies in a west facing valley at an altitude of 602 m to the north and above Wastwater, England’s deepest lake. The catchment comprises steeply sloping walls; with summits in excess of 825 m. Scoat Tarn shows a sediment signature of severe acidification in recent years as a direct result of human-induced acid deposition, and the location is one of the UK Upland Waters Monitoring Network of sites, whose data show the lake has recovered to some extent the last two decades.
Seven of the group sensibly met at the Wasdale Head Inn where we set up camp and spent an enjoyable evening in the pub eating drinking and watching Belgium knock USA out of the World Cup. The eighth decided to play a league tennis match til 8.30pm and then drive to the Lake District arriving just in time for last orders and a welcome pint of Lakeland Ale already purchased by the team.
In the morning, after a quiet night’s sleep accompanied by incessant bleating sheep, squawking birds, cuckoos and general noisy countryside, the reality of it all struck home and the tough fieldwork we had come here for arrived. A short drive along the edge of Wastwater and we arrived at the car park. Eight rucksacks packed to the brim with boats, ropes and coring equipment, we set off into the hills for a slightly daunting 500m climb over 4km.
Several hours and several miles (or km) later we reached Scoat Tarn. The aim was to collect 3 short gravity cores and a longer sediment record using a piston corer. To get the latter, we had to set up a rig with a stable working area from which we could operate the piston from. Our design was successful (it was worth carrying the ladder all that way!) and we managed to extract a one meter core from 18 m of water that will probably encompass the last 1000 years of environmental history for this upland catchment and what a catchment a stunning cirque basin in the southwest fells of one of the most beautiful valleys in England…..
We returned home to Liverpool the next morning with bags of sediment and a huge sense of achievement, my first PhD samples in the bag! Thanks to the team; Richard Chiverrell, John Boyle, Daniel Schillereff, Jen Clear, Hugh Smith, Amy Lennard and Agata Marzecova.
