We thank the reviewer for their helpful comments.

Regarding the first point about the repository, we wish to clarify that the provided links point to the public repository, which includes all scans and band traces that have been tagged by the core owners as publicly accessible. This does not include work-in-progress band traces or pre-publication core images. The reviewer may have trouble accessing the entire repository at once via the first Zenodo link because it is quite a large file (>100 GB). We also wish to reiterate from the manuscript text that the data visible on Zenodo are a snapshot of the current public repository. The repository is “living” (see below justification of repository curation) and the second Zenodo link contains information on how to connect directly to the CoralCache server. Once connected to the server via an FTP client, anyone can browse files or download individual files.

The data provided are a repository. We consider a repository a central storage location where specific types of datasets are stored, managed, and curated. This definition is consistent with CoralCache. It contains organized CT-scan and X-ray datasets of coral cores, coupled with observer interpretation files of the annual banding patterns. The data are managed by the actions within the CoralCT application, which inherently manages access, backups, and organization. The data are effectively curated as a community effort (i.e., the nature of users depositing scans and their interpretations through CoralCT is curation of these data in consistent, organized formats).

Regarding the second point about summarizing progress made, this is a good suggestion and we have added Figure 4 to address this. Figure 4 shows bar charts of numbers of cores and numbers of bands measured broken down by user-defined regions. This gives a current snapshot of progress made in collating cores across regions and analyzing them.

We thank the reviewer for these suggestions. In particular, we added citation in two places to Ma (1934) to acknowledge the early measurements of growth rates from coral skeletal density variations. We did not cite Darwin for the reason noted by the reviewer, that annual density bands were not described.

We also added clarification earlier in the manuscript (see lines 116-119) that a previous publication describes the methodologies of growth measurements in CoralCT and that the present manuscript focuses on the data compilation into a public repository. Nevertheless, we agree that a figure showing coral growth bands and the main interface of the application would help provide key context to readers, and we therefore added Figure 1. We also made a few minor text clarification to sections 2.5 and 2.6, but it is important to note that those sections are describing steps to synthesize datasets generated by multiple observers. The methods of the actual growth measurements in 3-D are fairly complicated and described previously (DeCarlo et al., 2025), so the focus here is not to repeat those methods descriptions.
