Hidden Gems Archive

Each year ICES Journal of Marine Science finds a selection of articles curated by the Editor-in-Chief, recognizing them as Hidden Gems which stand out from other articles in the field through their research or topics covered. The authors of these articles are then invited for interviews to discuss their articles and research.

Discover below the full history of interviews conducted in this Hidden Gems series, with new content added periodically over time.
