Specific Comments

Abstract

• Line 9–11: Thank you for pointing this out. The repeated sentence has been removed to improve clarity.

Introduction

The Introduction has been reorganized for improved clarity and structure. A more extensive description of D. delphis clicks, whistles, and burst-pulsed sounds will be added, along with known correlations with behavior.

• Line 19–23: This section has been moved to the end of the Introduction, as suggested.
  
  
  
  
• Line 23–26: The Introduction now begins with “This data descriptor…”.
  
  
  
  
• Line 26–27: The phrase “high-sampling” referred to the high sampling rate of each recording. This sentence has been revised for clarity and to avoid redundancy.
  
  
  
  
• Line 29: The words “including short-beaked common dolphin” has been removed, as it appears unnecessary.
  
  
  
  
• Line 35: The sentence has been revised for clarity.
  
  
  
  
• Line 35–36: The sentence has been restructured to reflect that the communication function of pulsed sounds is still under investigation. The corresponding line (Line 39) has been moved up, and possible functions are now discussed later in the paragraph.
  
  
  
  
• Line 36: “Pulsed sounds” are now better defined, with relevant references.
  
  
  
  
• Line 36–38: This section now includes a more detailed description of burst-pulsed sounds, including their context and characteristics, as well as their known behavioral associations in D. delphis.
  
  
  
  
• Line 43–44: This sentence has been simplified for clarity.
  
  
  
  
• Line 51–52: The repetition has been removed.
  
  
  
  
• Line 52–62: These lines, along with Figure 1, have been moved to the “Materials and Surveys” section, as they were too specific for the Introduction section.
  
  
  
  
• Line 63–64: The repeated sentence has been removed.
  
  
  
  
• Line 64–65: Elements previously found in Lines 19–23 have been integrated here to better contextualize the dataset and highlight its significance.

Materials and Surveys

• Line 69: Figures have been renumbered to reflect the revised structure.
  
  
  
  
• Line 70–74: This passage has been rewritten for clarity and conciseness. The figure legend now includes the name of the study area.
  
  
  
  
• Line 79: The term “parameters” has been replaced with “procedures.”
  
  
  
  
• Line 80: The term “computational processing” has been replaced with a clearer description indicating that no filtering or modification was applied to the raw acoustic recordings.
  
  
  
  
• Line 90: It seems that the disclaimer (lines 212–214) added in the initial version of the manuscript was missing its second part. The disclaimer has been updated. Specifically, we added the following sentence: “The DOLPHINFREE project obtained a favorable opinion from the Ethical Committee for Animal Experimentation of Languedoc Roussillon (CEEA-LR) for request #26568.” However, these documents are not available online.

Additional details about the fishing net (e.g., mesh size, length, and material) and its use have also been included in the Methods section.

Conclusions

The Conclusions section now includes a more comprehensive paragraph reinforcing the value of the dataset, its potential applications in behavioral and conservation research, and its contribution to open-access marine mammal acoustic data.

We thank you for your constructive and overall positive comments on our manuscript. We particularly appreciate your recognition of the usefulness of the acoustic dataset, the clarity of the manuscript sections, and the quality of the figures.

In the final version, we plan to revise and improve the Introduction and Methods sections based on comments from all referees. Regarding your concern about behavioural state classification, we agree that these assessments can be subjective and may not always represent the entire group or account for overlapping behaviours. Therefore, we will include a brief description to acknowledge these limitations and provide context for interpreting the behavioural data.

We also appreciate your careful identification of typos and grammatical issues. These will be corrected in the revised version. We provide explanations below for some specific comments.

• Line 16: We agree that “two-dimensional movement” may be unclear in this context and does not accurately reflect the intention of the sentence. Since the dataset includes audio recordings from four synchronised hydrophones, the directionality of sounds can be analysed using polar coordinates (elevation and azimuth angles), hence the two dimensions. However, to improve clarity, we will revise this sentence to refer explicitly to these angular measurements.
  
  
  
  
• Table 2: The title will be revised to: “Description of column headers in visual observation data (XLSX) files” to better reflect its content.

Once again, we sincerely thank you for your helpful and thoughtful feedback.

To address your concerns regarding behavioural data, we have added the following aspects in the revised manuscript and in the dataset available through Zenodo:



(i) The data was initially collected as relative percentages of each behavioural state, to reflect the different behaviours exhibited within a group of dolphins and/or the several behaviours exhibited simultaneously by a same individual (mainly attraction & socialisation during our surveys).

(ii) As a result, text in sub-section 'Observation notes' (lines 123-128) and Table 2 have been updated to precise the behavioural data collected.

(iii) The dataset available on Zenodo has been updated to include the initial relative percentage of each behavioural state recorded during the surveys



Again, we thank you for your constructive comments.
