Disaster Recovery: Archaeological Collection at JamestownBy Melba J. Myers

From the perspective of collections care, the flooding of the basement of the Visiter’s Center at the Colonial National Historical Park at Jamestown during Hurricane Isabel can be considered the most dramatic incident resulting from the hurricane in Virginia. A classic collections disaster–from the controversy over how it could have been prevented to the drama and magnitude of the recovery effort, it will provide lessons to collections managers of archaeological materials for years to come.

This summary will focus on the first phase, the immediate first-aid recovery effort starting two days after the hurricane when the first responders arrived on the scene, to the transport of the collection near the end of November from their temporary home, in a warehouse provided by Fort Lee, to a longer term treatment facility in Newport News, Virginia.

On September 18, 2003 a storm surge which contained water from the tidal James River, as well as seepage from a nearby brackish swamp, poured into the basement collections storage area. However the water came in, it was strong enough to knock over at least one of the stacked 8-drawer artifact cabinets and it resulted in 5 feet of standing salty water lasting for at least 1 1⁄2 days. The artifacts were stored in cardboard (chipboad) trays in drawers lined with Ethafoam within powder coated metal cabinets.

For several days before the hurricane, BMS-CAT, an international contractor out of Fort Worth, Texas, specializing in fire and water damage recovery, had positioned people and equipment in Virginia and were ready to respond to the call from the National Park Service.

In addition, NPS personnel from both the Northeast Museum Services Center in Boston (Conservator, Sara Wolf, among others) and from the Museum Resource Center in Washington, D.C. (archaeologists and collections managers) rushed to the scene, overcoming fallen trees and other obstacles on the way. Standing water was pumped out of the basement, holes were drilled in the bottom of the cabinets to drain them, and the cabinets, still full of wet artifacts in chipboard trays, were transported on pallets to Fort Lee, Virginia east of Petersburg.

to pop open locked file drawers. The paper materials that had been submerged by the flood were immediately sent to Fort Worth for freeze drying. These materials have now been returned, and because freeze dried materials are physically fragile, they are being scanned to make digital back-up versions of the original documentary materials.

The collection catalog was backed-up electronically prior to the storm. It was printed out in three volumes shortly after the collection arrived at Fort Lee and an effort was started to get a more accurate estimate of the total number of artifacts. There were 290 artifact cabinets, located in a large room of the Fort Lee warehouse. Most catalog items contained far more than one object. The approximate artifact estimate eventually became almost a million artifacts.

There were two obvious imperatives that drove subsequent recovery procedures:

*Artifact Stabilization: The decision had been made before leaving Jamestown that all the artifacts that had been submerged needed to be rinsed off with DI H

2O to remove

soluble salts, if at all possible before the artifacts had a chance to dry out. BMS-CAT would do this, but triage procedures ensuring that the most vulnerable materials were washed first, and that appropriate drying methods were used for each material class were to be established by conservators.

*Health Concerns: Because the ubiquitous chipboard container trays immediately began to produce a vast range of mold types,

Disaster Recovery Courses On-line from SOLINET

*New* distance education class allows you to study at work or home. Three two-hour sessions allow for flexibility in your busy work schedule. Begin the process of writing a disaster plan for your institution. Make this workshop a team-building activity with tangible results--a plan that will benefit your staff in a time of need.

Developing a Disaster Plan(Web-Based Training)

Wednesday, February 18, 2004, with mandatory follow-up sessions on March 10, 2004 and March 31, 2004.

To prevent unnecessary loss of materials, institutions needknowledgeable staff and written plans for dealing with emergency situations so that fewer disasters occur and damage is minimized. Disaster planning requires the support and commitment of staff from many departments, including facilities and fiscal affairs. Plan preparation is more successful and effective when undertaken by a committee with staff representatives from across the institution.

Taught in 3 two-hour sessions over the course of six weeks, this class guides participants through the development of a written disaster plan. This web-based workshop is designed to support the work of an institutionʼs disaster planning committee. Homework assignments will require input and support from a variety of staff members.

The modules cover: Establishment of a planning structure,information gathering, including risk assessment and resource list development, setting recovery priorities, an overview of recovery procedures, plan development, and working with disaster recovery vendors.

This workshop is designed for staff members responsible for organizing, writing, and implementing an institution-wide disaster preparedness plan in academic, public, or special libraries; archives; or historical societies. Participants are invited to submit their completed plans for review.

Partial funding for this workshop has been provided by a grant from the National Endowment for the Humanities, Division of Preservation and Access.

Cost is $135 SOLINET members ($125 early bird, $160 lateregistration), $185 Non-members ($175 early bird, $210 lateregistration).

Damaged and Deteriorated Photographic Print Materials: Compensation for Loss

A Workshop Funded by The Andrew W. Mellon Foundation, Hosted by the J. Paul Getty Museum, Los Angeles, CA. March 22-26, 2004

Utilizing the Photographs Collection and Paper Conservation facilities of the J. Paul Getty Museum (JPGM), this five-day course will investigate compensation techniques employed in the conservation of damaged and deteriorated historic and contemporary photographic prints. Demonstrations of techniques will be carried out by experienced conservators and innovators in the field.Intensive laboratory sessions will be dedicated to hands-on practice and experimentation with a variety of compensation challenges; treatment solutions will be explored over the course of the workshop. Topics to be addressed will include color and light theory, inpainting media and techniques, inserting methods for losses in photographic paper, historic coating procedures, isolating layers, work space design, ethics, artistʼs intent, and exhibition aesthetics. Compensation issues with a wide variety of photographicprocesses from the 19th and 20th centuries will be examined during the week.

Eligibility: The workshop is open to specialists in photographconservation who have had limited access to equivalent training. Enrollment is very limited.

Subject: AIC Announces Historic Structures Symposium

State of the Art Techniques for Monitoring and Protecting Historic StructuresSaturday, March 27, 2004. Columbia University, New York, NY (8:30 am - 5:00pm).

This one-day symposium will focus on technologies developed in other fields that could have significant uses in historic preservation and architectural conservation. Interested participants will include architects, engineers, architectural conservators as well as owners and managers of historic buildings. Attendees will see and hear presentations on instrumentation for purposes of monitoring deterioration and structural integrity of buildings and monuments. Participants are eligible for 6 AIA Learning Units.

Cathodic protection is a cutting edge corrosion prevention technique proven after years of use in the shipbuilding, highway infrastructure and petrochemical industries. The large stock of early iron and steel framed buildings in both the United States and the United Kingdom has driven research into this corrosion protection system.

health authorities decreed that the trays should be pulled out of the drawers as a first priority. All personnel working in the main room would wear protective gear. Paper (documentary materials) had already been removed and artifacts made of wood, most of which had been treated in the past, were also pulled very quickly and sent out to be stabilized elsewhere. The only organic remaining was bone.

During the six week period at Fort Lee the two imperatives held sway, sometimes jostling against each other, forcing a re-focus of the labor force in one direction or another.

As is almost universally true of archaeological collections, the artifacts were organized in the cabinets by provenience, NOT by material class. Once a wash order was established: bone; metal; glass; delft (the glaze can pop off easily by drying soluble salts); followed by everything else, it was then necessary to have personnel that could identify these material classes and pull them out of the drawers. Archaeological glass or metals, for example, can appear in many visual guises, and the identification of Delft is easy only if you have done it. Conservators, curators, and collections managers with experience in mid-Atlantic historical archaeological collections were all applied to this sorting activity, while other NPS and BMS-CAT personnel hauled the color tape coded drawers of sorted materials into the wash/dry assembly line. Emily Williams and two of her interns were called on early and were involved in the critical triage decisions.

The above the water line artifacts had to be dealt with simultaneously. Steel cabinet drawers located below the water line were rusting fast, partly due to Ethafoam liners that were holding brackish water in contact with the bottom of the drawers. The cabinets were also warped and were determined to be unrecoverable. They would be turned in for scrap metal. Sample visual examination indicated that artifacts that had not been submerged would have to be looked at more closely at a later date, but that at the moment they needed to be removed as fast as possible from the metal cabinets and packed for transport. Packaging these in newly labeled Zip-Lock bags was a chore for new arrivals and volunteers.

It was clear that rinsing off the salts and carefully drying the artifacts would be all that was needed to stabilize some of them, however it was also obvious that many other treatments would be necessary to

In some cases the strength of the water flow disturbed the chipboard trays and distributed artifacts around the drawer. Fortunately, each individual artifact had a catalog number label on it.

1. IntroductionBiodeterioration of organic cultural

heritage materials is a common problem. While the conventional techniques forremoval of fungal material from paper are proofing sufficient in many cases, the removal of discoloration caused by fun-gal pigments is yet a problem in paper conservation.

There are very rare reports on the re-moval of fungi from paper by lasers. 1,2

A far-UV krypton fluoride (KrF) excimer laser was able to remove AspergillusNiger mould from filter paper whileviable spores and mould fragments were released into the atmosphere. 3 Actually UVB radiation of a 308 nm XeCl exci-mer laser can be used for the treatment of skin mycosis fungoides. 4 That meansthat UV laser radiation can deteriorate fungi.

However, irradiation of cellulose with even a near-UV excimer laser at 308 nm resulted in photo-oxidative degradationof the paper substrate, accompanied by an increase in oxidized groups content (carbonyl or carboxyl) and a severedecrease in degree of polymerisation. 5,6

That means that successes of anti- fungallaser treatments with UV lasers areaccompanied by paper deterioration.

It could be shown, on the other hand, that Nd:YAG lasers light at 532 nm leads to negligible paper deterioration in a flu-ence regime for practical laser clean-ing.5,6

2. Results and DiscussionPure cultures such as Penicillium,

Trichoderma etc. (Fig. 1) were subcultured in petri dishes containing malt agar with the so-called slide culture technique (Fig. 2). A block of sterile agar was cut out of a Petri dish (A) and was placed upon a ster-ile slide resting on a bent glass tube within a sterile Petri dish (B). A few spores of a fungus were inoculated at the edges of the sterile agar block (C) and topped with a cover-glass (D) for incubation on eithercotton filter paper or handmade rag paper from around 1600. A disc of moist filter paper in the dish maintained humidity for the culture. After incubation at room temperature for three weeks the paper samples were taken out of the dishes and immersed in 70 % Ethanol for removal of hyphae and mycelia and deactivation of the remaining conidia. After drying coloured stains were left (Fig. 3 and 4). To reduce shrinks and folds, samples were slightly moistured (1 hour) using a Gore-Tex laminate and then flattened for easier handling during laser cleaning.

Selective laser treatment of paper: PaReLa ProjectEC contract no. EVK4-CT-2000-30002

The variety of combinations of different types of foreign matter (dirt) on paper objects presents a spectrum of complex cleaning problems in paper conservation. Current cleaning methods using conventional means (solvents, mechanical) are not always sufficient to solve these problems. For instance local cleaning of paper in the vicinity of sensitive media is a common conservation problem. Laser technology can now practically and safely be used for selective and local cleaning.

This laser technology was developed in the cooperative research project “PaReLa”, funded by the European Commission. The consortium included paper conservators, researchers and engineers from The Netherlands, Spain, Austria, France, Germany, Ireland, Sweden and Greece.

The research program focussed on the examination of the interaction of laser light with paper and parchment supports, media and materials to be removed. The results of the research show that a green Nd:YAG laser is the most suitable for paper treatment, since side-effects in terms of ageing and mechanical changes are minimal or completely absent. Paper conservators played an essential role in the design of a laser workstation for paper objects, which had to be an attractive alternative to conventional cleaning methods in terms of applicability, safety and costs.

Currently a number of conservation studios are employing this innovative method in their daily practices. For more information please contact Art Innovation.

PaReLa Project

Date: 20 Nov 2003From: Sjoerd Postma <[email protected]>Subject: Workshop on laser cleaning

Art Innovation presents a two-day workshop on laser cleaning in art conservation.

The main objective of this course is to provide conservators and conservation scientists with information and knowledge about laser cleaning of art objects. This course will give insight in the advantages and disadvantages of laser cleaning in different application fields and hands-on experience with different kinds of lasers. There is no special knowledge, skill or scientific background necessary for this course, but a professional relationship to the conservation field is preferable. The workshop takes place at Art Innovation, Hengelo, The Netherlands <URL:http://www.art-innovation.nl/>.

Practical work is done at the laser laboratory of Art Innovation. Course topics include:

* Theory of light and lasers (general) * Laser cleaning techniques with special attention on paintings, paper and sculpture * Laser safety at the workplace * Monitoring and documentation

During the course, participants will have the hands-on experience of working with a UV (248 nm) and a Nd: YAG laser (532 nm) on different art objects. Courses in 2004: March 18-19, 2004 April 29-30, 2004 May 27-28, 2004 July 1-2, 2004 September 23-24, 2004 October 23-24, 2004

These specimens were laser-treated in a computer-controlled laser cleaning system with a high pulse energy diode pumped Q-switched Nd:YAG laser operating at 532 nm and a pulse duration of <8 ns. 7 Extensive removal of visible remnants of fungi components were ob-served in the case of e.g. Penicillium (Fig. 3 and 4) and Alternaria. On the basis of various diagnostic tools as microscopy and multi-spectral imaging etc. the findings can be discussed in terms of surface damage due to embedded fruit bodies, discoloration due to pigmentsecretion, and structural destruction caused by enzymatic digestion of cellulose.

stabilize the entire collection, particularly corroding metals. Over the period of six weeks while the first-aid cleaning was being performed by BMS-CAT, the NPS managers, were working on what would come next and how to pay for it. Estimates of how many artifacts; of what materials and condition; and what type of facility would be necessary; were factored into a proposal that went up thand was eventually approved.

During the last week in November, 2003, the entire collection was moved to a larger rented facility located in Newport News, closer to Jamestown. Approximately $9,000,000 was approved to cover a 3-5 year project headed up by Sara Wolf from the NPS, Northeast Museum Services Center. A conservator site-manager and 15 other conservator/technicians will be hired to complete the recovery effort. The new technician slots will not be permanent NPS positions, but a contract situation which will allow for some benefits. At this moment NPS staff are in the process of adapting the Newport News warehouse to office and lab space. As of the deadline for this newsletter no information is available about where to look for these position announcements.

The cardboard trays had been manufactured with a paper covering set down with an adhesive that dissolved while submerged in water (probably animal skin glue). After the water was drained out of the cabinets, glue settled and adhered artifacts to the bottom of the tray.

Lorraine brought the business meeting to a close and asked David Voelkel, programs committee co-chair, to introduce the night’s speaker.

Program: David introduced David Hahn, our host for the event, who will speak on the topic “Conservation and Collections Management Issues and Concerns for Aviation Collections.” David is the assistant director and acting agency collections head at the Virginia Aviation Museum.

David began his talk by explaining his position and issues facing him

and the Aviation Museum. The Museum is under the Science Museum of Virginia and it is different from traditional museums in several ways. Most of the collections and exhibits are interactive. Also, they don’t have traditional curators. Conservation issues are also handled differently.

A major issue they deal with regularly is “Do we restore the artifact or preserve it as a document?” And if we restore, do we use new materials or old? There is a huge

cost difference between old and new materials in the aviation field. The curator’s job is to serve as a “warning light on the panel,” to make sure things are done right. His stance is that if you use new materials and shiny paint you are not really restoring. You need to use real conservators on historical machines and materials. This is not what is always done in the aviation field.

Planes are very complex structures. The life span is intended to be short, for example 90 days for World

War II planes, so they used metals next to others that would cause interactions. Salvagers are also pulling them out of lakes and oceans now. There is new thinking on how to treat an old plane. Most now consider it an historic document, so they want to make what is there last and don’t want to just slap a coat of paint on it.

An example of a preservation problem is the Blackbird parked outside in the front of the Museum. It was previously stored at Edwards Air Force Base, which is in the desert. That situation was good for metal. Now it is in Virginia and

outside, and there is a lot of active corrosion. He is trying to get a cover for it to help the situation.

David next discussed the “enemies of collections.” These include well-meaning but uninformed staff or board members, unskilled conservators, and rich or political friends who want to decide how things are done. He has had to deal with these people a lot with this collection. They can all cause damage with improper restorations.

His goal is to arrest deterioration within the collection. If there is not enough money to achieve that, he wants to at least slow it. David has been trying to get items under cover, if possible, but not to seal them up. He is currently trying to build a framework for operation and staffing, so that when dollars begin to come back in to state agencies they can start doing things exactly right. He is prioritizing needs in preparation for a better time.

These concerns parallel those at historical sites and art museums right now. When the Aviation Museum opened in 1987 there was no heat or air conditioning. It became a state property in 1990. He has worked on

climate issues since he has been there. For the future, he wants to make contacts within the conservation community. He hopes that the economy will make an upturn that will help museums.

David next gave a tour of the collection on display, highlighting conservation priorities and issues. He explained that his major goal is to preserve these things for future generations to see.

Thanks, David, for a great program!
