In connection with the 14th International Coral Reef Symposium (ICRS 2020, https://www.icrs2020.de/), originally planned to be held in Bremen, Germany, in July 2020, arrangements were made with the journal Oceans to produce a Special Issue associated with the conference to which conference delegates could submit papers based on their oral presentations or posters. This is the second Special Issue linked to the Bremen ICRS.

However, due to the coronavirus pandemic, the conference was postponed. A virtual conference was held as the 14^th ICRS online in July 2021, and an in-person meeting (15^th ICRS) is now expected to take place in July 2022 in Bremen, Germany.

Nevertheless, to provide attending delegates with an appropriate outlet for their material, a first Special Issue (entitled “The Future of Coral Reefs: Research Submitted to ICRS 2020/21”) based on papers submitted by July 2021 is in the process of publication in Oceans. Twelve accepted manuscripts have already been published online after being finalized (https://www.mdpi.com/journal/oceans/special_issues/coral_reefs) by 8 November 2021 (more will be published at a later date), thus ensuring the publication of 2020/21 manuscripts in the near future.

However, since the follow-up in-person meeting is now to take place in July 2022, it has been agreed that a second Special Issue will be published in 2021/22 in Oceans. This sister volume will retain the same name and continue to reflect the conference themes. Manuscripts for this second volume need to be submitted by 30 September 2022.

Instructions for submission may be found at https://www.mdpi.com/journal/oceans/instructions. All submissions will be subject to standard reviewing procedures to ensure the high quality of the writing and the accuracy of the content. Oceans has no restrictions on the length of manuscripts, and hence short papers based on either oral presentations or posters will be considered.

This second volume will be edited by Oceans editors in cooperation with an editorial support team led by Prof. Dr. Christian Wild, chair of the 14^th and 15^th ICRS.

Authors whose first language is not English are encouraged to submit manuscripts, but they need to have their text checked by a native English speaker or make use of MDPI’s English editing service (https://www.mdpi.com/authors/english). Only manuscripts that are well written in high-quality English will be considered and sent out for review.
