The Australian Historic Shipwreck Preservation Project: In situ Preservation and Long-Term Monitoring of the Clarence (1850) and James Matthews (1841) Shipwreck Sites

Increasingly, archaeologists are opting for on-site examination, reinterment, and in situ preservation of underwater cultural heritage sites as the first option in the management of sites at risk, as opposed to the more traditional excavation, recovery, conservation, and display/storage methods. This decision will inevitably be based on significance assessment, degree of perceived risk, and resourcing issues. However, long-term monitoring must become an integral part of these management programmes in order to quantitatively evaluate the effectiveness of the in situ preservation techniques employed. In 2012 the Australian Historic Shipwreck Preservation Project (AHSPP) was awarded a large Australian Research Council (ARC) Linkage Grant, enabling ten partner organizations and three Australian universities to collaborate in one of the largest multi-organizational maritime archaeology projects to be undertaken in Australia to date. One of the major aims of the project is to develop a protocol for the excavation, detailed recording and reburial of significant shipwrecks under threat, fostering a strategic national approach for the management of underwater cultural heritage (UCH) sites at risk. Two historically significant shipwreck sites that are considered under threat were chosen for this longitudinal comparative study — the Clarence (1850) located in Port Phillip Bay, Victoria; and the James Matthews (1841) which lies in Cockburn Sound, Western Australia. Both sites have been preserved in situ using two very different but innovative remediation strategies. More importantly, long-term monitoring programmes have been implemented on both sites, which will characterize changes in the reburial environment and the effect on the reinterred materials. In this way, the efficacy of both in situ preservation techniques will be systematically tested, providing a comparative analysis of practical protocols for the long-term protection and management of underwater cultural heritage.     

Working with Tradition: Towards a Partnership Model of Fieldwork

This paper explores the interaction between fieldworker and “tradition bearer” over an extended period of time, in the context of an ethnographic study of singing traditions in the southern Pennines of England. Using examples, it examines the negative as well as the positive aspects of the exchange, with particular emphasis on mutuality and reciprocity. It charts the development of key relationships and the ways in which they have come to maturity and achieved equilibrium. Careful thought is given to the role of the fieldworker in respect of active/passive, interventionist/non-interventionist stances. Aspects of performance, commercialisation, networking, promotion, and media relations are discussed. Following a consideration of ethical and moral issues, including exploitation and advocacy, the paper suggests a working model of partnership as a way forward for future productive field-based research into traditional expressive arts.     

Thelodont fish and conodonts from the Early Devonian of Reefton,New Zealand

Thelodont scales and associated fragments of conodont elements identified as Turinia sp. cf. Turinia australiensis and Ozarkodina sp. cf. Ozarkodina buchanensis respectively are described for the first time from the Early Devonian Murray Creek Formation of Reefton, New Zealand. The conodont and thelodont components of the fauna suggest a late Pragian to early Emsian age for the assemblage.     

Remarks on the pattern of septal insertion in rugose corals

Wang, G., Percival, I.G. & Li, R., 25.2.2015. Remarks on the pattern of septal insertion in rugose corals. Alcheringa 39, xxx–xxx. ISSN 0311-5518

Well-preserved specimens of the Hirnantian (latest Ordovician) rugose coral Lambeophyllum? corniculum He from the Yangtze Platform of South China, clearly show how catasepta (minor septa) are inserted, confirming the model proposed by Weyer in the 1970s. Our observations indicate the insertion of counter lateral septa and their neighbouring catasepta on the counter side takes place in exactly the same manner as that of the subsequent metasepta and catasepta. We propose abandoning the use of the term counter lateral septa. Therefore, exclusion of the pair of counter lateral septa reduces the number of protosepta from six to four.
