The vast Heron-Allen collection contains 740 slides of foraminifera, including specimens from historic expeditions such as HMS Challenger and Terra Nova. A complete catalogue of the slide collection is available as an Excel spreadsheet.
Edward Heron-Allen (1861-1943) was a remarkable individual of diverse interests. His scientific work was focussed on foraminifera.
The collection includes specimens from around the globe, collected between 1873 and the 1930s. Many notable research expeditions are represented, including:
A complete catalogue of the collection is available as an Excel spreadsheet.
Each of the 740 slides contains more than one species. Most, particularly those collected during notable research expeditions, have detailed collection information, such as:
Specimens were picked from the ocean bottom deposit (OBD) collection and the washed residues from each expedition:
Many slide specimens have corresponding bulk samples from the same locations which can be used for future analysis.
There are 508 residue samples from 450 stations in the Heron-Allen and Earland collection of forams.
The majority come from coastal locations around the British Isles and Western Europe, but also from localities off the coast of Africa (Kermiba) and in the Mediterranean.
Most of the other specimens in the Heron-Allen slide collection came from these residue samples, which can also be re-sampled for further analysis.
