13:00End of the conference

Despite not meeting in person, the conference title remains

“NORA 4 – Reconnecting across Europe”

and the conference aims to do just that by taking place on, a virtual meeting platform which allows participants to “walk” around and interact with one another much as you would in an in-person conference. The use of this interface is financially supported by the Rich North Sea programme.
The interface is simple to learn and the NORA Secretariat will be offering a series of drop in sessions from 11-12CET/10-11GMT in the week running up to the conference to introduce those new to the format. Further details will be shared with registered participants, but if you would like to get a head start you can try a walk-through demo here….

NORA 4 Partners

The NORA Conference:
Purpose and Organisation of Programme Items

The NORA 4 Organising Committee, NORA Advisory Board and NORA 4 Scientific committee look forward to welcoming you to the NORA 4 conference from 23rd – 25th November 202. It is the active engagement and energy of the wider NORA community that we are seeking to provide a platform for during the conference. To this end, there are many elements of the conference which seek to deviate from a traditional conference focused on the sharing of scientific knowledge and achievements. Please attend prepared to participate in NORA-wide discussions, whether you are an established scientist, a non-academic project partner, or a student. We wish to create a forum where all voices can be heard. 

In order to give you a flavor of what is in store, here is a brief overview of the conference sessions.

Student Session (registration required)

At this postgraduate workshop, students at all stages of their research project will present their research plans or results, exchanging knowledge. Aiming to create a supportive environment, the workshop will be open not only to students, but to whoever is interested in joining the event as mentors or interested parties. There will, however, be a limited number of attendees to maintain a relaxed atmosphere. This session presents a great opportunity for networking and future collaborations. There will be a student-only social event held on the evening of the 22nd November. Registration and abstract submission for the student session is now open. The abstract deadline is July 15th 2021. We hope to see you there!


The NORA 4 Organising Committee and the NORA Advisory Board are delighted to be hosting two global leaders in restoration of Ostrea species from around the world. We look forward to learning about oyster restoration from long standing and fast growing projects from the Pacific coast of the USA and Australia, and in finding out what lessons can perhaps be transferred. 
Find out more about our keynote speakers Chris Gillies and Betsy Peabody.

Poster session

Posters are a great way to present activities and results, especially if you would like to discuss them further with interested parties face-to-face. In, you have the possibility to discuss new results from restoration and research projects of the NORA community.

NORA Advisory Board/Secretariat Panel discussion

NORA is fortunate to have a dedicated Advisory Board, reflecting the geographic and professional diversity within the network. This session will provide an opportunity for the network to hear directly from the Advisory Board, and to pose their own questions in an open discussion.
