Metadata: 2014, DMP, Zone 3 - Dogger Bank, Statistical Analysis of Marine Mammal Data (Teesside A and B)
Abstract:
Statistical analyses of Hi-Def aerial survey marine mammal observation survey data for the Dogger Bank development zone between 2009 and 2012. The scope of work requested from DMP Statistical Solutions UK Limited was a package of outputs that reflect the spatial distribution of several species/groups through time. The scope of species and species-groups were agreed with Forewind prior to analysis. The requirements were: 1. Annual relative abundance surfaces where possible for identified groups. 2. Relative and absolute abundance surfaces, over all surveys, for: a. Harbour porpoise. b. ‘Potential harbour porpoise’ grouping. c. Harbour porpoise & ‘Potential harbour porpoise’ grouping combined. d. White-beaked dolphin. e. Minke. f. Grey seal. The statistical models give expected density surfaces (numbers per square km) and upper and lower confidence bounds, potentially over a range of times e.g. monthly, seasonally, yearly. The models are based on a type of Generalized Additive Model (GAM) using radial basis functions with spatially adaptive knots and radius parameter (Walker et. al. 2011, Scott-Hayward et. al. (TBD)). The predictions in these files are given in a form adjusted for the following availability figure (absolute abundances) and a form UN-adjusted for availability (relative abundances).

| Internal code | Internally assigned metadata identifier | 19349 |
| 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. | 2014, DMP, Zone 3 - Dogger Bank, Statistical Analysis of Marine Mammal Data (Teesside A and B) |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Statistical Analysis of Marine Mammal Data (Teesside A and B) |
| 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. | af97ca72-a35a-4d3c-b38f-c63095b08887 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-2507 |
| 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 | 2009-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-12-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 0.02 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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 |
