Protocol for reporting finds of archaeological interest Full text Prepared by August 2005 Wessex Archaeology British Marine Aggregate Producers Association and English Heritage Protocol for reporting finds of archaeological interest August 2005 prepared by Wessex Archaeology Purpose other relevant parties to provide appropriate advice. In 2003, the British Marine Aggregate Producers Association (BMAPA) and English Heritage (EH) The aim of the Protocol is to reduce any adverse jointly published Marine Aggregate Dredging and effects of marine aggregate dredging on the the Historic Environment: Guidance Note. The historic environment by enabling people working Guidance Note sets out the character and in the industry to report their finds in a manner importance of the marine historic environment, that is convenient and effective. and describes best practice in dealing with archaeological matters in the course of planning The archaeological finds made by aggregate marine aggregate dredging. workers are important because they shed light on our predecessor’s use of the sea and seabed. The Guidance Note includes details of measures The information that these finds bring to light to mitigate the effect of marine aggregate helps archaeologists to better understand what dredging on the historic environment, including happened in times long (and not so long) ago. It the implementation of protocols to report and also allows archaeologists to better protect deal with finds made in the course of dredging. aspects of our history that should be conserved on behalf of future generations. Archaeological Rather than have many different protocols, each finds from the seabed also help the public to designed for different dredging areas and catch a glimpse of the past in an otherwise potentially with varying provisions, BMAPA and unfathomable environment. English Heritage decided it would be preferable to have a single unifying protocol applicable to Further information about marine aggregate all dredging areas, vessels and wharves. The dredging and the historic information is set out existence of a single protocol would ensure in Marine Aggregate Dredging and the Historic consistency and therefore encourage Environment: Guidance Note (BMAPA/English participation by everybody involved in the Heritage 2003). marine aggregate dredging industry.

This Protocol sets out best practice in the reporting of finds of archaeological interest. The 2 The Protocol Introduction All Staff The Protocol has been designed to deal with Companies shall draw the attention of all discoveries made on the seabed, onboard and at relevant staff to the potential for archaeological wharves. A separate – but similar – series of material to be found in the course of aggregate actions applies in each case. dredging and inform them of the possible importance of such finds.

The Nominated Contact for the Company will liaise with English Heritage. Vessels and Wharves Managed by Other Operators Terms and Roles There may be instances where third party Nominated Contact vessels and wharves may either dredge or receive aggregate from a licence area subject to Each Company shall nominate one of their staff this Protocol (i.e. managed by a BMAPA member to act as the single point of contact for all company).

In order that The Protocol requires actions to be taken by the such constraints be removed as swiftly as various parties. The timescales within which possible if they are not merited on these actions are taken may be critical to archaeological grounds, it is important that safeguarding finds of archaeological interest, Companies receive archaeological advice and to avoiding unreasonable disruption to promptly. For their part, English Heritage may commercial operations. want to obtain specialist advice, on specific finds and their treatment for example. It is Where Staff or an Officer on Watch notice expected that English Heritage will provide something on a vessel, it is important that action initial formal advice to the Nominated Contact is taken immediately. The precise position on the within two working days of receiving information seabed of a find or anomaly will be a key piece from the Nominated Contact. of information. The occurrence should be noted and brought to the attention of the Master / Site In view of these arrangements, the overall Champion straight away, so that positions can be timescale between a find occurring, and formal calculated. It is important that positions are archaeological advice being provided, should be calculated before any more dredging passes are no more than five working days. made in the vicinity of the anomaly / suspected find. Time may also be of the essence in If anyone finds or takes possession of wreck, checking the dredging gear for any artefacts that they are committing an offence if they do not may have become lodged in the draghead or report it to the Receiver (Merchant Shipping Act screens. 1995 s. 236). Although the Act does not state a time limit within which notification must occur, Where staff notice something on a wharf, the it is a matter of policy that the Receiver expects key concerns are to safeguard artefacts before to be notified within 28 days of the find they are lost within the volume of material occurring. being processed, and to establish the cargo – and hence the vessel and the area of seabed – that the find originated from. Immediate notification Types of Find of the Site Champion is required. ‘Finds’ are considered here to mean all forms of The Site Champion will be able to take the artefact that can be found on the seabed. To be actions necessary to safeguard finds, and an artefact, the thing must have been made, information relating to them, in the short term. modified, used or transported by people, i.e. It is important, however, that information is their presence on the seabed is ‘artificial’ or passed on promptly so that decisions – which ‘cultural’ rather than ‘natural’. may have operational implications – can be taken for the medium term. It is expected that For legal purposes, finds from the seabed fall the Site Champion will inform the Nominated into two categories. ‘Wreck’ has a specific legal Contact on the same working day that a find is definition broadly encompassing all sorts of made. materials that came to be on the seabed as a direct result of once being aboard or part of a On receiving a report, the Nominated Contact vessel. has a number of obligations that require discussion with third parties, and regarding All other finds are referred to here as ‘non- which the Nominated Contact may wish to take wreck’. ‘Non-wreck’ includes things such as advice.

Where the Nominated sites on the shore. Contact is absent, Companies are expected to provide a deputy fully capable of carrying out A third category of find, ‘treasure’ as defined by the role. the Treasure Act 1996, is not relevant to this Protocol, as the Treasure Act is limited in its application to land above mean low water. 4 Ownership of Wreck Ownership of Non-Wreck Statutory law relating to ‘wreck’ is set out The law applicable to ‘non-wreck’ is largely principally in the Merchant Shipping Act 1995. common law, to be found in legal cases and The common law relating to wreck is to be found commentaries. in legal cases and commentaries. All wreck is presumed to have an owner, and Original Owners ownership is not lost through the passage of time. It is a legal requirement under section 236 Finds that are successfully claimed by their of the Merchant Shipping Act 1995 that wreck owners continue to belong to that owner, though material be reported to the Receiver of Wreck, the owner may be obliged to reward the finder in order to establish ownership and settle for having found and returned their property. salvage claims. If ownership cannot be established by the Receiver within one year of receipt of the report, the wreck becomes Unclaimed Non-wreck Material in Territorial ‘unclaimed wreck’. Waters On land, archaeological material is considered to Original Owners belong to the owner of the land in which it was found. The Crown generally owns the seabed Owners of wreck who are able to prove their within territorial waters, hence unclaimed non- ownership to the satisfaction of the Receiver of wreck material found within territorial waters is Wreck are entitled to have their property considered to belong to the Crown. In some returned to them on payment of a salvage cases a party other than the Crown owns the award. seabed, and in such instances unclaimed non- wreck material will be considered to belong to that party. Unclaimed Wreck in Territorial Waters Under the Merchant Shipping Act 1995, wreck Unclaimed Non-wreck on the UK Continental that is found in Territorial Waters and is not Shelf Beyond Territorial Waters claimed within a year automatically becomes the property of the Crown. In some areas – usually While the Crown generally owns the seabed close to the shore – the Crown’s right to within territorial waters, its interest in the unclaimed wreck has been granted to another seabed beyond territorial waters to the limits of beneficiary. the UK Continental Shelf is limited to sovereign rights to explore and exploit its natural resources. These rights do not extend to finds on Unclaimed Wreck on the UK Continental Shelf the UKCS, hence unclaimed non-wreck on the Beyond Territorial Waters UKCS beyond Territorial Waters is considered to belong to the finder. The stipulations of the Merchant Shipping Act 1995 apply to all wreck that is brought within UK territorial waters, irrespective of where it was Non-wreck in Marine Aggregate Licence Areas recovered. However, the provisions in respect of Crown ownership apply only to wreck recovered In the case of marine aggregates, extraction from territorial waters. Wreck recovered from activity is licensed by The Crown Estate. Through outside UK territorial waters that remains this license, ownership of mineral resources (and unclaimed after one year of reporting is not any associated non-wreck material) present on claimed by the Crown, and in most the seabed is transferred to the licensee once circumstances will be returned to the finder the material is raised. Any non-wreck material once any expenses incurred have been settled. discovered on board the dredging vessel or at the wharf will therefore become the responsibility of the licensee. 5 Discoveries on the Seabed possible in the vessel’s log together with the time and exact vessel position.
