LAKE DISTRICT AREA

It is located in the western-central sector of the UK, in England, at about 54.3ºN. There are around 20 large-medium-sized lakes, and a large number of small lakes (tarns). Most of these lakes are located at low altitude (less than 100 masl). In July 2014 we carried out a survey of surface sediments and water in six lakes in this area: Windermere, Coniston Water, Esthwaite Water, Blea Tarn, Louchrigg Tarn, and Bigland Hall. We studied the bulk organic matter, as well as the specific compounds (n-alakanes, alkenones and diols). On the base of these lines of evidence, we selected Esthwaite Water for our paleoenvironmental research and two long sediment cores were taken in March 2015.

The NAOSIPUK project is focused on two UK areas with a large number of glacial-origin lakes: Lake District National Park and Loch Lomond & The Trossachs National Park. They have been selected because of their important environmental features, as well as their latitudinal location. Most lake depressions of these areas were dug out during the pervious glacial periods, and filled up with water in the subsequent melting phases. Two surface sediment surveys were performed in these areas in July 2014 and October 2014 to identify the two lakes with the best features for paleoenvironmental reconstructions.

LOCH LOMOND AREA

It is located in the northwestern sector of the UK, in Scotland, at about 56.1ºN. There are around 22 large-medium-sized lakes (lochs), and a large number of smaller lochs and lochans. Most of these lakes are located at low altitude; for example, Loch Lomond, the largest lake in this area, is at around 10 masl. In October 2014 we carried out a survey of surface sediments and water in three lakes: Spling Lochan, Dubh Loch, and Chon Loch, and two extra sediment samples from the Loch Lomond mid-basin and south-basin were given by Dr. L. Vihermaa and Dr. S. Waldron. The same geochemical studies as in the lakes in the Lake District were carried out, and we selected the Loch Lomond to take a sediment core in the Summer 2015.
