After the Event: Response, Stabilization, and Salvage of Photographic Collections

Photographic materials have complex structures, specialized needs, and inherent preservation vulnerabilities; salvaging these materials safely after a disaster incident can sometimes be more challenging than salvaging collections that are primarily paper. This workshop will address disaster response with a focus on photographic collections. Presenters will share practical procedures for efficient initial response and stabilization of a disaster scene and will give specific guidelines on salvaging and caring for photographs following a disaster. The session will conclude with a brief, hands-on exercise in which participants will have a chance to witness and practice simulated salvage of photographic materials

Moving from positive to negative : working across disciplines on large photograph digitization projects

Historic images are in demand—especially those available for discovery online. At the same time, digitizing large photograph collections can be daunting, particularly when a project involves balancing access and preservation with tight budgets, limited staff, and fragile or deteriorating objects. Outside collaborators can help leverage available resources and increase the effectiveness and reach of the project but identifying and recruiting partners and keeping diverse stakeholders on the same page can be challenging. Panelists will discuss collaborating across disciplines on two large digitization projects, the Religious News Service photographs, 1945-1982 (about 60,000 prints and negatives) and the Los Angeles Department of Public Works photographic materials (about 700,000 prints, negatives, and slides)

Exploring, exploiting and evolving diversity of aquatic ecosystem models: A community perspective

Here, we present a community perspective on how to explore, exploit and evolve the diversity in aquatic ecosystem models. These models play an important role in understanding the functioning of aquatic ecosystems, filling in observation gaps and developing effective strategies for water quality management. In this spirit, numerous models have been developed since the 1970s. We set off to explore model diversity by making an inventory among 42 aquatic ecosystem modellers, by categorizing the resulting set of models and by analysing them for diversity. We then focus on how to exploit model diversity by comparing and combining different aspects of existing models. Finally, we discuss how model diversity came about in the past and could evolve in the future. Throughout our study, we use analogies from biodiversity research to analyse and interpret model diversity. We recommend to make models publicly available through open-source policies, to standardize documentation and technical implementation of models, and to compare models through ensemble modelling and interdisciplinary approaches. We end with our perspective on how the field of aquatic ecosystem modelling might develop in the next 5–10 years. To strive for clarity and to improve readability for non-modellers, we include a glossary
