Metadata: DPLUS0045 Anguilla Still Image Analysis
Abstract:
Still image analysis of the groundtruthing data collected as part of the Darwin Plus funded project "Mapping Anguilla’s ‘Blue Belt’ Ecosystem Services". The project develops local capacity to undertake comprehensive marine resource assessments of Anguilla’s ‘Blue-Belt’, delivering best practice guidance for combining satellite and acoustic surveys, to extend mapping into deeper waters for the first time.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 9394 |
| 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. | DPLUS0045 Anguilla Still Image Analysis |
| 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. | CEFAS30b1c54b-b176-41ae-9ef7-7534bf77f183 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS19319 |
| 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. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2016-09-11 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-09-29 |
| 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. | Images were collected using a small drop-down camera frame built by Cefas. The groundtruthing survey ran for 10 days in September 2016 following the MBES survey, The frame collected both high definition video and stills of the seabed in carefully selected locations around Anguilla. Using the acoustic data and local stakeholder engagement, stations were positioned around Anguilla to best describe the different habitats and substrates present. The camera system consisted of a Bowtech Video Camera and two GoPro cameras attached to a custom-made frame. At each station the vessel was positioned to the upstream side of the location and the camera was lowered to just above the seabed. The vessel was then allowed to drift over the position while the cameras collected high definition video and stills data. Each camera station lasted for 10 minutes before the camera was recovered and the vessel moved on to the next station. The still and video data were assessed for benthic habitat composition. Benthic habitat composition per photograph was assessed in terms of percentage cover using Coral Point Count® (v4.1); a software tool for determining community statistics of benthic photographs. Percentage cover was derived by randomly assigning 24 points over each photograph and then identifying the species or substrate at each point. Benthic habitat types were selected based upon the classifications derived by Mumby and Harborne (1999)[1] with adaptations for Anguilla’s management purposes and habitats specific to Anguilla.
