Metadata: 2022-2023, Bangor University, Marine Characterisation Research Project, Marine mammal Acoustic Surveys (WP11)
Abstract:
This data series was collected for the Marine Characterisation project (MCRP) which forms part of the Morlais tidal energy project, managed by Menter Môn and funded by the European Regional Development Fund and The Crown Estate. The series is comprised of acoustic hydrophone data used to detect the presence of marine mammals (primarily harbour porpoise). These data were recorded during monthly boat based marine mammal observation surveys. Please see other data packages associated with WP11: 2022-2023, Bangor University, Morlais, Marine Characterisation Research Project - Echosounder surveys (WP11) 2022-2023, Bangor University, Marine Characterisation Research Project, Seabird and marine mammal observations (WP11) Access to the MCRP data is strictly subject to the MCRP Data Terms of Use. Please ensure that you read and understand the Terms of Use prior to using any of the data as you will be bound to comply with the same. The MCRP Terms of Use are the prevailing Terms of Use and supersede that of Marine Data Exchange Terms of Use in relation to MCRP data.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Survey A originally used the 13 parallel transects designed by Natural Power (Morlais 2019, Figure 2.2). The transect lines of varying length were orientated in a west-east direction and were spaced approximately 0.92 km apart. The vessel travelled south through the transects when the tide is flooding North and travels north when the tide is ebbing south, to avoid double counting seabirds drifting on the water. Whilst performing transects, the vessel maintained a speed over ground of approximately 10 knots. However, following the maiden survey on 15/05/2023, it became evident that completing the original Survey A and Survey B on the same day was not possible. Therefore, to allow both surveys to be completed, only 6 or 7 transect lines were carried out each month. The transect lines were alternated amongst months i.e., odd numbers in one month, followed by even numbers the next month. Survey B used the 10 zigzag transect routes designed by SEACAMS2 (Veneruso et al 2019, Fig 2.2), combining 2 observation teams and a high-frequency stereo hydrophone system (Marine Ecological Research). The transect lines were spaced 1 km apart. This survey design allowed collection of concurrent acoustic and observational information for marine mammals within the MDZ. The hydrophone was primarily deployed to detected harbour porpoise, whose almost continuous vocalisations (Sørensen et al 2018) make them suitable for acoustic detection. The vessel moved with the direction of the tide during the survey, reducing the background noise and increasing the likelihood of acoustic detections. One transect was surveyed per month and transects were alternated equally amongst months. Whilst performing these transects, the vessel maintained a speed over ground of approximately 10 knots. |
