Metadata: 2006-2007, Sussex Sea Fisheries District Committee, Development of an Appropriate Hierarchical Classification Scheme for the Supervised Classification and Accuracy Assessment of acoustic ground discrimination system (AGDS) Data
Abstract:
Increasingly zonal management through spatial planning is seen as a tool to reconcile competing resource demands in the marine environment. The Government’s commitment to a system of spatial management is recognised in national marine policy, a key function of the intended Marine Bill is develop a spatial approach to marine planning. The process and efficacy of spatial resource management is informed by the availability and quality of relevant seabed descriptions. Currently broad scale habitat descriptions at a scale relevant to the inshore zone are not available to marine resource managers and those undertaking resource exploitation. The rationale of a project undertaken by the Sea Fisheries Committee was to develop methodologies and datasets using existing SFC assets to inform a consents decision making process. This work has a range of applications with particular relevance to marine conservation and fisheries management and the aggregate extraction consenting process. Previous studies by the SFC, funded through the ALSF, have developed datasets to describe inshore fisheries and tested the ability of SFC assets to map the seabed. During this project the SFC explore the relevance these methods to management and their ability to provide information relevant to marine spatial planning.An acoustic ground classification system (AGDS) collected data on routine fisheries patrols during between 2006 and 2007. To interpret and validate this acoustic dataset a bespoke survey using a towed video system was undertaken at 270 field sites in the summer of 2007. The data was used to create a hierarchical classification scheme which enabled a supervised classification and accuracy assessment of the AGDS data.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 5440 |
| 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. | 2006-2007, Sussex Sea Fisheries District Committee, Development of an Appropriate Hierarchical Classification Scheme for the Supervised Classification and Accuracy Assessment of acoustic ground discrimination system (AGDS) Data |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | MEPF Project Reference:MAL0020 2007/8 Extension |
| 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. | d0b7c130a2ff5de9a122264544107077 |
| Resource Identifier | This is the code assigned by the data owner. | 19744 |
| 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 | 2006-04-20 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2007-07-03 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| 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. | The Sussex Sea Fisheries Committee’s Fishery Patrol Vessel (FPV) ‘Watchful’ is equipped with an AGDS (QTC™ View 5) manufactured by the Quester Tangent Corporation of Canada. The QTC™ system is linked to a Simrad™ 50Khz single beam echosounder and output data is processed and logged to an onboard PC using proprietary software ‘Impact’ develop by QTC™. Subject to suitable operating conditions the system is normally operated during routine enforcement patrols. |
