Meetings of the Porcupine Marine Natural History Society take place at venues throughout Great Britain and Ireland and may in the future be held Europe-wide. These include:
- An annual conference involving the presentation of papers, progress reports and discussion on a particular theme.
- Workshops on topical issues or identification of particular taxonomic groups.
- Field meetings which provide an opportunity to learn to identify marine species and to appreciate the ecology and geographic variation of marine communities.
- Joint meetings with other Societies.
