We gratefully acknowledge the positive feedback on the manuscript, and interactive webpage and datasets. We are delighted to read that the reviewer considers the IESDB as a valuable resource for teaching, research, and industry applications, which was the original aim of this project.

We fully agree with all the minor comments, which are addressed below.

C1 (R#1): I could not find the link from https://digital.csic.es/handle/10261/266163 to https://iesdb.eu/.

R1 (Authors): The link to https://iesdb.eu has been included in the data repository (https://doi.org/10.20350/digitalCSIC/14586).

C2 (R#1): Line 369: I don’t think that there a many active nuclear waste repository in rock salt formations. Please consider rephrasing the sentence.

R2 (Authors): We agree, but we also have to acknowledge that they have been considered for nuclear waste storage in different countries. The original sentence was: "Salt caverns are widely used as seasonal and long-lasting reservoirs for hydrocarbon products (e.g. oil crude and natural gas) and nuclear waste repositories (e.g., Ozarslan, 2012; Wang et al., 2017; Warren, 2017)", and has been rephrased to (lines 368-370 of the revised manuscript): "Salt caverns are widely used as seasonal and long-lasting reservoirs for hydrocarbon products (e.g. oil crude and natural gas), and in some cases have been considered as potential repositories for nuclear waste (e.g., Ozarslan, 2012; Wang et al., 2017; Warren, 2017)".

Thank you very much for the positive comments and for the suggestions.

We carried out this work aiming to make it accesible, easy to understand, and useful for a general audience interested in the wide subject of evaporites. We are pleased to read that your opinion is in line with the original project aim.

We gratefully acknowledge your suggestions (and references) about including the Sesimbra, Monte Real, and São Pedro de Moel evaporite structures. We will review all the available information and references of these structures and they will be included in the next IESDB update, which is planned for the last quarter of 2023.

We gratefully acknowledge the positive evaluation of the manuscript and the insightful and constructive comments on the IESDB webpage and database structure. Thank you for supporting the publication of this manuscript. The suggestions and comments are addressed below.

C1 (R#2): The map is sometimes unresponsive, at least in my case. Also, it would be nice to add some satellite imagery maps and geological maps as extra layers. This would make the database even easier to use for people who are not familiar with the area.

R1 (Authors): We have tried to maximize the responsivity of the interactive map. Our tests in Chrome, MS Edge, Mozilla Firefox, and Opera web browsers seem to work properly now. Regarding the possibility of adding extra base maps (satellite imagery or geological maps), they are commonly subject to copyright statements or CC licenses that do not allow their complete reproduction in the IESDB webpage. We will consider to request permission to the rightsholders in order to add the Global Lithological Map (GLIM, Universität Hamburg; Hartmann and Moosdorf, 2012) and satellite imagery in the next update of the IESDB website.

C2 (R#2): Add a link/comment/suggestion box where people can suggest new entries of other salt structures/work to be included in your database. I saw your UPDATES section, but you can design a form where people can add all the details needed to include new salt structures in the database.

R2 (Authors): The internal structure of the IESDB Database is complex and it would be very difficult to have a way for the users to add data to each file, or new sites. We do prefer to leave the UPDATES section as it is, since the new salt structures suggested by the community must fulfil the indexation criteria specified in the manuscript and webpage. We do, however, encourage the submission of new or revised information via the CONTACT section of the website, and have explicitly mentioned this in the revised version of the manuscript. In this way we can incorporate to the database data and improvements by the community:

Original sentence: "The IESDB aims to be a dynamic project open to collaboration and with constant improvement and expansion".

Rephrased to (lines 204-205 of the revised manuscript): "The IESDB aims to be a dynamic project open to collaboration and with constant improvement and expansion. We encourage users to contact the database managers and submit new information or suggest corrections to expand and improve the database".

C3 (R#2): In the seismic database - Can you provide links directly to the lines themselves and not only to the repository? I tried searching for two random lines and struggled to find the data.

R3 (Authors): Most of the seismic lines are normally included in the SIGEOF Data Catalogue (©Instituto Geológico y Minero de España; IGME), and most of them are only available under specific request and as part of a survey pack (i.e., not available individually). This means that a direct link to the seismic lines themselves cannot be generally included. However, all the information related to each seismic line, as well as the link to the request form, can be found at the IESDB webpage and at the interactive search engine provided by IGME (https://info.igme.es/SIGEOF/). 

C4 (R#2): It would be nice if you would consider adding a Digital Outcrop Model database as well within the structure of your datasets. If there are not many such resources available, this might spur some researchers to create them.

R4 (Authors): We find this suggestion an excellent idea. However, not all structures are present in outcrops, and for those that are, adding Digital Outcrop Models (DOMs) would require a major update of the database structure and webpage, as well as reasonable time for photogrammetric data acquisition in the field prior to the creation of the DOMs. We will consider this suggestion for the next planned IESDB update (4Q 2023) and, if viable, carry out pilot Digital Outcrop Modelling in some outcropping evaporite structures. Additionally, we will link existing DOMs published in open-access repositories (e.g., V3Geo, eRock).
