Metadata: 2003-2005, RPS, Humber Gateway, Marine Mammal Survey
Abstract:
RPS, commissioned by the Institute of Estuarine and Coastal Studies, conducted a marine mammal survey from October 2003 to April 2005 to assess the distribution, abundance, and seasonal trends of grey seals, common seals, and harbour porpoises near the Humber Gateway Offshore Wind Farm off the Holderness coast and the wider south-east England area. Findings confirmed year-round presence—particularly of harbour porpoise and grey seal—with notable seasonal peaks, but overall numbers were low to moderate compared to other UK regions. The study highlighted the importance of using specialist observers for accurate population estimates, the need to account for seasonal trends in environmental impact assessments, and emphasised compliance with UK and EU conservation legislation. Recommendations include ongoing monitoring to capture sensitive periods, further assessment of potential anthropogenic impacts, targeted mitigation to protect regulated populations, and the strengthening of international cooperative frameworks to safeguard threatened marine mammals.

| Internal code | Internally assigned metadata identifier | 39785 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2003-2005, RPS, Humber Gateway, Marine Mammal Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Marine Mammal Survey |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 7496b119-0bd1-42f7-9905-78fc62138ed8 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-681 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2003-10-27 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2005-02-09 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Boat and aerial bird surveys were conducted during which incidental sightings of marine mammals were recorded. In addition, a dedicated marine mammal surveyor was used during four of the vessel-based survey trips. The survey utilised vessel-based and aerial methodologies, systematic twice-monthly observations, dedicated marine mammal observers, and analytical techniques such as GLM and distance sampling, alongside a literature review of relevant legal frameworks. |
