Connecting Content: Galapagos Islands 1905-1906 Expedition Field Notes Digitization, Project Update

Since my last blog post I have finished scanning the field notes of Alban Stewart, the expedition botanist, and I have moved on to Washington Ochsner’s geology field notes. The pages are unbound and very brittle, so I have to be quite gentle with them and handle them as little as possible.

During the year the expedition was in the Galapagos, the scientists went to several islands multiple times. It seems that after the expedition these notes were reordered by island, so I check closely while scanning to make sure that the pages are not out of place.

Ochsner’s geology journal is divided into four sections:

The first, and largest section, is comprised of notes and general observations. It describes geological formations, strata, and rock composition. In this section he often describes a formation or an island’s origin, and explains how it may relate to other islands in the Galapagos chain. This section also contains interesting figures and maps to help visualize the descriptions. The maps and figures show rock strata and geological formations— such as lakes, cliffs, craters, and volcanic formations—with numbers or alpha-notations connecting features to the notes. These have been some of my favorite parts of the notes. I enjoy cartography, particularly old maps, and it is fascinating to read through Ochsner’s notes and connect them to his drawings.

Ochsner called the second section “occasional ideas.” These seem to be general thoughts that did not fit in with the notes on specific islands. It also contains citations for literature related to his observations.

The third section is a rock specimen catalog. This section contains a list of rock specimens Ochsner, and other members of the expedition, collected on the various islands. He assigned the specimens a unique catalog number and also a number relating to where they were found.

The final section consists of photograph metadata. This is descriptive information that corresponds to images taken during the expedition.

I am almost finished digitizing Ochsner’s field notes, and, after receiving further training with the imaging hardware and software, I will probably begin taking high resolution digital images of finch specimens. It should be lots of fun!

Connecting Content: 1905-1906 Galapagos Expedition Field Notes

The California Academy of Sciences was recently awarded a National Leadership Grant from the Institute of Museum and Library Services for a project called Connecting Content. This pilot project involves digitizing and providing access to expedition field notes and avian specimens from a 1905-1906 expedition to the Galapagos Islands, and I get to create the digital images! At the end of the project we will make the field notes available through the Biodiversity Heritage Library and specimen images available through the Encyclopedia of Life.

Besides the scientific and research value of this collection, it is also one of the Academy’s oldest collections. While the expedition was in the Galapagos the 1906 Earthquake devastated San Francisco and destroyed the old Academy building along with many collections. The Galapagos expedition’s field notes and specimens became part of the foundation materials for the new Academy.

I have begun scanning the field notes of Alban Stewart, the expedition botanist. The notes are divided into three sections. In the first section Stewart tracked plant species he encountered and recorded them using a numbering system, and he provided brief notes about them.

The second section is composed of his journal. In the journal Stewart describes in greater detail the various species and locations of plants found on the many islands of the Galapagos Archipelago. Stewart would survey an area and describe species he found and note any particulars of their surroundings, including if they were abundant or scarce. Stewart’s journal traces the biodiversity of the flora in relation to other islands and continental regions. In his notes he often mentions other regions where these plants grow, and whether or not a species can be found on other islands in the chain.

The final section is a chart of air and water temperature readings. I was surprised to find that the water and air temperature readings were often very similar.

I am working in the project lab on the first floor, across from the rainforest dome. It is a high-tech lab where visitors can walk by and view ongoing projects and research being conducted live. It has been kind of fun to scan, view, and process the images on three large computer screens while visitors can peer in through the glass. We set up a display with some related artifacts from the expedition—such as a pith helmet, some of the field notes, an old camera, and an expedition group photograph—for visitors to view as well so that they can get an idea of what we are doing. A few special tours have come through the lab and it has been great to interact with them and explain the project, why it is important, and what we hope to accomplish. It is quite rare in the archive world to have this much engagement with the public, so I am hopeful we can help demystify archives a little and show people what we are doing to make important primary materials more accessible.
