There are a number of bryozoan collections in the Natural History Museum that can potentially be used for ocean acidification type research projects. They originate from a number of different expeditions from the 1870s to the late 20th century.


Organisms included: 


Geographical location covered:
  • Bimini Islands (USA)
  • Indonesia and the coral-sea - Siboga and Snellius expeditions
  • Southern Oceans - Terra Nova expedition
  • The Discovery and Challenger expeditions had a broad geographic coverage.
Timespan covered:
  • Challenger expedition - 1872-76
  • Siboga expedition - 1890s
  • Rattlesnake expedition - 1846-50
  • Discovery expeditions - early 20th century

Curation and collection management

Preservation and storage:

In most cases, the specimens are spread throughout the general collection. The exceptions are those from the Challenger expedition and the Bimini Islands (USA) collection.

Specific notes:

  • Bimini Islands (USA) collection is large and unpicked.
  • Siboga expedition collection mostly consists of dry specimens in slides.
  • The preservation history is generally unknown for the Rattlesnake and Challenger expedition specimens.
  • Destructive sampling is not allowed for the Rattlesnake or Challenger specimens.
Database information:
  • Specimen level databases are generally lacking. However, the entire Snellius expedition collection should be databased.
  • Specimens from the Challenger expeditions are in the process of being databased and photographed.
  • There is a British Museum catalogue for the Rattlesnake expedition collection.

Associated collections

Many of the Challenger expedition specimens are off limits for destructive sampling as they are types and/or of historical significance. However, the bulk samples that they were taken from exist in the Ocean bottom deposit collection and, in some cases, the Ocean bottom residue collection. These are more readily available for destructive sampling.
