WA 64490-96 BritNed Interconnector Scheme dataset https://portal.medin.org.uk/portal/start.php?tpc=010_e0ff832b-d6f8-3c46-88d7-6d2c16b09e7e A watching brief was undertaken in 2006 during ground works associated with geotechnical investigations of the BritNed Interconnector UK landfall site on the Isle of Grain, Kent. No pre-modern archaeological features or finds were observed. Holocene alluvium was found in borehole BH120 below made ground and a section of the core at -24.85 to -25.24mOD was analysed. Pollen evidence indicates oak and hazel woodland and an acorn cup produced a 14C date of 9030-8720 BP (late Mesolithic). Abundant charcoal suggests human activity or natural fires. Plant and animal remains indicate gradual marine inundation, with brackish intertidal creeks developing. During cable laying offshore in 2010, the previously unreported wreck of a small wooden vessel in poor condition was encountered at approximate position 450546 E, 5741447 N (UTM Zone 31N). Archaeological evaluation suggests that the unidentified wreck was exposed by sandwave migration after 2008. It probably dates to the late nineteenth or twentieth century and was probably a small fishing or recreational boat or World War II patrol or service boat. During cable burial operations off the Isle of Grain in 2010, part of a previously unreported wooden wreck was discovered in the cable trench at approximate position 346411 E, 5705324 N (UTM Zone 31N). It was completely buried during a subsequent archaeological diving inspection. Size, extent of survival and function of the unidentified vessel are unknown. The recovery of a cuprous fastening suggests that it is unlikely to predate the early nineteenth century. 20130807 20110411
