The peachy museums of the world harbor a secret: They're dwelling solid to millions upon millions of natural history specimens that almost never run into the low-cal of day. They prevarication hidden from populace view, typically housed behind or to a higher house the populace demo halls, or inwards off-site buildings.

For paleontologists, biologists as well as anthropologists, museums are similar the historians' archives. And similar most archives – hollo upward of those housed inwards the Vatican or inwards the Library of Congress – each museum typically holds many unique specimens, the entirely information nosotros withdraw hold on the species they represent.
The uniqueness of each museum collection way that scientists routinely brand pilgrimages worldwide to see them. It also way that the loss of a collection, equally inwards the recent heart-wrenching burn inwards Rio de Janeiro, represents an irreplaceable loss of knowledge. It's akin to the loss of menage unit of measurement history when a menage unit of measurement elderberry passes away. In Rio, these losses included one-of-a-kind dinosaurs, mayhap the oldest human remains always establish inwards South America, as well as the entirely sound recordings as well as documents of indigenous languages, including many that no longer withdraw hold native speakers. Things nosotros i time knew, nosotros know no longer; things nosotros mightiness withdraw hold known tin no longer hold upward known.
But straightaway digital technologies – including the internet, interoperable databases as well as rapid imaging techniques – decease far possible to electronically aggregate museum data. Researchers, including a multi-institutional squad I am leading, are laying the foundation for the coherent job of these millions of specimens. Across the globe, teams are working to convey these "dark data" – currently inaccessible via the spider web – into the digital light.
What's hidden away inwards drawers as well as boxes
Paleontologists oft depict the fossil tape equally incomplete. But for to a greater extent than or less groups the fossil tape tin hold upward remarkably good. In many cases, in that location are enough of previously collected specimens inwards museums to assistance scientists response their inquiry questions. The number is how accessible – or non – they are.

With the vision as well as investment of funding agencies such equally the National Science Foundation (NSF) inwards the United States, numerous museums are collaborating to digitally convey together their information from key parts of the fossil record. The University of California Museum of Paleontology at Berkeley, where I work, is one of 10 museums straightaway aggregating to a greater extent than or less of their fossil data. Together through our digitized collections, nosotros are working to empathize how major environmental changes withdraw hold affected marine ecosystems on the eastern coast of the Pacific Ocean, from Republic of Chile to Alaska, over the end 66 1000000 years.
The digitization procedure itself includes adding the specimen's collection information into the museum estimator organization if it hasn't already been entered: its species identification, where it was found, as well as the historic menstruation of the rocks it was establish in. Then, nosotros digitize the geographic location of where the specimen was collected, as well as withdraw hold digital images that tin hold upward accessed via the web.

Significantly, the cost of digitally aggregating the fossil information online, including the tens of thousands of images, is remarkably small-scale compared amongst the cost it took to collect the fossils inwards the outset place. It's also less than the expense of maintaining the physical safety as well as accessibility of these priceless resources – a cost that those supposed to hold upward responsible for the museum inwards Rio land were non willing to cover, amongst disastrous consequences.
Digitized information tin assistance response inquiry questions
Our group, called EPICC for Eastern Pacific Invertebrate Communities of the Cenozoic, quantified only how much "dark data" are acquaint inwards our articulation collections. We establish that our 10 museums incorporate fossils from 23 times the number of collection sites inwards California, Oregon as well as Washington than are currently documented inwards a leading online electronic database of the paleontological scientific literature, the Paleobiology Database.

To response these questions, all the relevant fossil data, drawn from many museums, needs to hold upward easily accessible online to enable large-scale synthesis of those data. Digitization enables paleontologists to run into the wood equally a whole, rather than only equally a myriad number of private trees.
In to a greater extent than or less cases – such equally records of yesteryear languages or the collection information associated amongst private specimens – digital records assistance protect these invaluable resources. But, typically, the actual specimens stay crucial to agreement yesteryear change. Researchers oft even as well as thence demand to brand key measurements straight on the specimens themselves.
For example, Berkeley Ph.D. pupil Emily Orzechowski is using specimens beingness aggregated yesteryear the EPICC projection to attempt the thought that the body of body of water off the Californian coast volition decease cooler amongst global climate change. Climate models predict increased global warming volition atomic number 82 to stronger winds downward the coast, which volition increment the coastal upwelling that brings frigid waters from the deep body of body of water to the surface – the drive of San Francisco's famous summertime fogs.

Understanding response to yesteryear alter is non only restricted to fossils. For example, nearly a century agone the manager of the Museum of Vertebrate Zoology, Joseph Grinnell at the University of California, Berkeley, undertook systematic collections of mammals as well as birds across California. Subsequently, the museum re-surveyed those precise localities, discovering major changes inwards the distribution of many species, including loss of many plane species inwards the Mojave Desert.
Influenza A virus subtype H5N1 key facial expression of this go has been comparing of the deoxyribonucleic acid from the almost hundred-year-old museum specimens amongst deoxyribonucleic acid of animals hold upward today. The comparing revealed serious fragmentation of populations, as well as led to the identification of genetic changes inwards response to environmental change. Having the specimens is crucial to this form of project.
This digital revolution is non only restricted to fossils as well as paleontology. It pertains to all museums collections. Curators as well as researchers are enormously excited yesteryear the ability to hold upward gained equally the museum collections of the world – from fossils to specimens from live-caught organisms – decease accessible through the nascent digitization of our invaluable collections.
