Calcareous sponges are represented in the following historical marine collections that may be of use for ocean acidification research:
The Discovery collections originate from a number of different expeditions that took place from 1901-1999. The collection of pteropods may be of particular importance for ocean acidification research, and there are a wide variety of other marine specimens as well as ocean bottom deposits and residues.

The collections of National Museums Scotland include up to 1 million marine invertebrate specimens, most of which are preserved in alcohol. There is also a comprehensive collection of microscope slides including tardigrades, amphipods and sponges. Find out more.
The collections at these institutions were surveyed for the UK Ocean Acidification Research Programme.
