Surface retreat rate from gullies at an eroding blanket bog, Aberdeenshire, UK.

Surface retreat rate (erosion rate) or peat from seven erosion gullies within an eroding blanket bog. The bog is on a large high-altitude plateau blanket bog in the eastern part of the Cairngorms National Park, Scotland, UK (56.93° N, − 3.16° E, 642 m asl). Within each erosion gully, 9 1m steel pins (threaded rod) were inserted into the peat until they reached bed rock or were almost competely submerged (but still visible). The pins were oriented in a 1m2 square with 0.5m between each pin. Approximately every 2-4 months the distance between the top of each pin and the top of the peat was measured (measuring to the lowest point at which peat surace intersects with the pin). The dataset shows: Date: date at which the measurement was taken Gully: The gully number (1-7) Pin: The pin number within each gully (1-9) dL: Change in exposed length of pin (cm) compared to the start date of 27/09/2022
