Galleon Character Area
Present Day Form
The Galleon character area is situated in the central part of the study area. The geology of the area is a complex anticline of Jurassic and Triassic bedrock overlain by glacial till (clay, sand and gravel debris deposited from ice sheets) known as the Elbow formation. The water depth across the area varies between 20m and 25 m with a deep water pit known as the Coal Pit (probably a Devensian palaeochannel) aligned N - S running to a depth of 80m with associated gravel terraces. The maximum tidal range is c3m. The seabed of the area consists of seabed ripples of gravely sand.
Sea Use: Present
The Galleon character area contains an active gas production field based around the Galleon and Clipper fields. The fields were discovered between 1985 and 1990 and have reserves of c 80 billion cubic metres which make them one of the major production areas of the southern North Sea. The pipeline infrastructure transports the gas to the Bacton Gas Terminal in Norfolk.
There is fishing activity in the area but this is compromised by the exclusion zones around the gas installation.
Sea Use: Past
The Galleon character area has been shaped by thousands of years of dynamic sea level changes and erosion and deposition. The relatively shallow nature of the sea bed means that the area was dry land almost certainly in the Upper Palaeolithic, Mesolithic and probably in the Neolithic periods.
Marine traffic would have crossed this area on a regular basis from the Roman period onwards using the Coal Pit deep water channel. The Coal Pit deep was historically one of the famous sole fisheries first discovered during the early smack fishing days of the 19th century. These fisheries were exploited from Hull and Grimsby during the winter when sole would congregate in vast numbers in the deep water guts such as Sole Pit and the Silver Pit.
The area is also part of the named fishing ground the Leman Ground on Close's Fisherman's Chart (UKHO 1953) and is described as a good fishing ground in between the shoals. In the south, June to Sept are good months. Fish: Plaice Soles Cod and Dabs. Large lumps of coal are often taken in the nets. The area was also an important herring fishery.
Archaeological Potential
The Galleon character area has potential for the presence of drowned land surfaces resulting from the fact that sea level has fluctuated between -120m and +10m over the past 500,000 years. From the period 500,000 BP to 22,000 BP (before present), human population levels were low, and little more than stray finds may be expected, although these may still be of considerable archaeological importance.
From 22,000 BP to 2100 BP parts of the North Sea were dry land and human population levels were higher, especially in the Mesolithic age. Finds dating to the Mesolithic have been found to a depth of 40m so any area of sea bed above that has potential for habitation. Inundation of the North Sea landscapes occurred between 10,000 and 6,000 BP and the most likely evidence for human occupation would be, therefore, Mesolithic in date.
Earlier Palaeolithic occupation is less likely to be found and later Neolithic occupation is likely to have been limited to the inshore and very highest of the banks and shoals such as the Dogger Bank. The area's position adjacent to the Coal Pit palaeochannel makes it prime habitation site. Consequently, there is some potential for surviving evidence of human activity within the area. Over the last 6000 years (if not more), humans have used sea faring vessels and so wrecks and related material may lie on the sea floor or be buried beneath the sea floor. UKHO and NMR data show no unnamed or named wrecks in this area.
Character Perceptions
The area is perceived as an offshore fishing ground and also as a gas production area.
