Методы сбора
The HydroMoth (Open Acoustic Devices) was configured for broadband recording at 250 kHz (Medium gain) with a 0.5–125 kHz band-pass filter and duty-cycled recording (300 s record / 5 s sleep). Data and metadata were structured for publication as a Darwin Core Archive (DwC-A). Because the device was not acoustically calibrated, amplitudes are expressed as relative dB FS (peak-to-peak) rather than absolute levels (dB re 1 µPa).
| Охват исследования | The encounter occurred off the Catalan coast within the Natura 2000 marine site Costes del Garraf (ES5110020). After the dolphin group was sighted, the vessel’s engine was switched off and the recorder was gently deployed at 5–7 m depth, where it remained until the encounter ended. The eight-minute segment analysed spans 09:36:25–09:44:30 (UTC+1) on 1 December 2024. Field notes—subsequently mapped to Darwin Core Event and Occurrence—include timings, species confirmation, number of individuals, recorder identity and depth, coordinates, sea state and brief behavioural context. |

| Контроль качества | An initial quality-control check (QC-0) verified file integrity, temporal consistency and agreement with the expected configuration (sampling rate, duration, etc). Whistles were manually reviewed and validated within the ROCCA module (PAMGuard) to exclude doubtful or very low-SNR contours. Clipped intervals were annotated in Audacity 3.7.5 and excluded before computing click metrics and classes with the PAMGuard Click Detector. The eMoF table specifies units, methods and remarks to ensure transparent and reproducible calculations and filtering rules. |
Описание этапа методики:
- Analysis: The audio files were screened in Audacity 3.7.5 to identify potential signal saturation (clipping). Two label types were created: HardClip (0 dBFS) and NearClip (−0.5 dBFS). Downstream analyses masked ±5 ms around these intervals. The audio was processed with PAMGuard v2.02.16 using two main modules: the Click Detector to detect clicks and ROCCA to visualise and select whistles. To obtain the actual (“real”) number of clicks, PAMGuard detections were cross-checked against the Audacity clipping labels. Real clicks were defined as those with a representative inter-click interval (ICI) of 0.5–100 ms and occurring outside the ±5 ms windows around NearClip/HardClip labels. Further methodological details are provided in the Zenodo record (DOI: 10.5281/zenodo.17534727).
- Data structure and access: The dataset is distributed as a Darwin Core Archive (DwC-A) containing Event, Occurrence, ExtendedMeasurementOrFact (eMoF) and SimpleMultimedia, along with meta.xml and the EML. SimpleMultimedia entries resolve to Zenodo, where all raw audio (WAV), PAMGuard project, configuration files and figures are preserved to support FAIR discovery and reuse. Linkage to the core follows the standard DwC convention in which each extension uses coreID = eventID (Zenodo DOI: 10.5281/zenodo.17534727).
- Key numerical results from the eight-minute segment analysed: Whistles: A total of 92 whistles were validated, with minimum–maximum frequencies between 7.6–13.0 kHz. These included convex, ascending and quasi-constant contours with harmonics. Clicks: PAMGuard automatically detected 21,853 clicks, of which 20,217 met the criteria for real clicks. Their mean relative amplitude was 134.99 dB FS (p-p) (relative, non-calibrated units). Based on representative ICIs, real clicks were classified as: Burst pulses (ICI ≤ 3 ms): 70%; Click trains (3 < ICI ≤ 10 ms): 13%; and Echolocation clicks (10 < ICI ≤ 100 ms): 17%. All metrics are included in the eMoF table.
