Sustainable Archaeology at the OAS Symposium

This past weekend staff from both Sustainable Archaeology Western and McMaster attended the annual Ontario Archaeology Society Symposium in Niagara Falls.

In addition to our workshop at the end of the day, we were in the book room for the day Saturday, and were able to have some great conversations with a number of professional archaeologists, students, and representatives of other organizations such as the Canadian Conservation Institute and the Canadian Museum of Civilization.

We received some great feedback on our use of digital tools and inventory management logic  for labeling and cataloguing of artifacts at Sustainable Archaeology, and enjoyed introducing people to the "immersive archaeological experience" using the Oculus Rift - a virtual reality headset that is designed for the gaming industry. The Oculus at  SA is used to immerse users in a reconstruction of the Lawson village site (located next door to SA: Western at the Museum of Ontario Archaeology) created in summer 2012 by the Sustainable Archaeology Animation Unit internship, using the Unreal game engine.

We look forward to continuing conversations from the weekend, and continue to welcome feedback on our draft Procedures and Practices document, available on our website. Thanks to the OAS for a great weekend!

"As it Happens": database development using Neo4J

Database development at Sustainable Archaeology "as it happens": the database team works with Neo4J .

Neo4j is used to power metadata queries, such as searches across attributes recorded for each artifact entered into the database.

This visualization of related nodes will be integrated into each element's record in the database, allowing a user to explore connections between different elements. For example, if the element of interest is an artifact, the user is able to explore the connections between that artifact and other related elements, such as the artifact's unit, and site of origin.

October at Sustainable Archaeology

Work study student Branwen applying labels

October has arrived with a flurry of activity, the shipment of several skids of our green artifact storage boxes, and some beautiful colours out back of the facility in the Medway Valley. This month we welcomed two new faces to the facility: Western work study students Ilsa and Branwen. Together they have been helping us to advance over one of the bigger hurdles we have here at the facility - the application of over 27,000 labels to the shelves of the mobile shelving units. Each individual box in the facility will be stored at a unique shelf address, which will be recorded in the database via the DM code barcoding system. Each label stores the information for two shelf locations, the "front" box, and the "back" box behind it.

Throughout the remainder of the month we will be preparing to host a workshop at the Ontario Archaeological Society Symposium in Niagara Falls on Saturday October 26th. Hope to see you there!

Sustainable Archaeology: Western is interested in purchasing a 3D printer to use in association with our 3D scanners and microCT to replicate archaeological artifacts. A request for quotation (RFQ) has been published on the Canadian Public Tenders website, MERX. The deadline for submissions is Friday, October 4th.

Flotation Machine in Action

Featured in a previous post, Sustainable Archaeology's soil flotation machine from R. J. Dausman Technical Services, Inc. was put through its paces today. A team from New Directions Archaeology Ltd. was on site to un-crate and set up the machine, running the first tests out in the Lawson village at the Museum of Ontario Archaeology, next door. They will be floating dry sediment samples over the next few days that they have collected from some recent excavations the company has been working on.

The machine requires access to running water for its initial fill, as well as access to a source of electricity for circulating the water in the tank. After its initial fill, the machine recycles water within itself to allow for light-fraction flotation, and heavy-fraction rinsing with an attached spray-hose. The material captured in the screens is then allowed to dry on newspaper before it is packaged, and later analyzed. The fine mesh, as seen in the images below, allows for the capture of tiny floating artifacts, such as tobacco seeds. A courser mesh filters the heavier fraction of sediment, which can include artifacts such as shell, bone and pieces of flaked stone tool.

Collections Repackaging at the Museum of Ontario Archaeology

Over the last week volunteers and work study students at the Museum of Ontario Archaeology have been working to prepare the Museum's collections for transfer to Sustainable Archaeology. The work includes the removal of any cardboard, paper bags, newspaper, and any other non-archival quality materials. When complete, the collections will be held in inert, acid free, archival quality materials, including polyethylene bags, acid-free tissue, and polyethylene foam. The repacking effort is guided by the Sustainable Archaeology Collections Procedures and Practices. The Procedures and Practices document, including standards for collections packaging can be viewed on our webpage. We are currently accepting feedback on this draft document, which be provided directly from the website by clicking the orange "Feedback" button to the left of the page.

 The repacking project will continue throughout the summer in the Museum's temporary gallery. Visitors to the Museum are invited to view the students and volunteers while they work, and to ask questions about the process and the collections.
