Metadata: CLYDAS - 2014A - Clyde herring acoustic survey 2014 - Clyde - Alba Na Mara
Abstract:
Daily folders (11) of Simrad format (.raw) acoustic data. Excel biological data for 5 pelagic hauls. Objectives: To conduct an acoustic survey designed to survey both the open and enclosed areas of the Clyde to ultimately provide an estimate of the abundance and distribution of herring and sprat. To obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection. All other species caught will be measured for length and weight to establish a length weight relationship. To gather passive acoustic data using a towed acoustic array to assess the presence of cetaceans.

Internal code | Internally assigned metadata identifier | 6194 |
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. | CLYDAS - 2014A - Clyde herring acoustic survey 2014 - Clyde - Alba Na Mara |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Clyde, Herring acoustic, Alba Na mara |
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. | Marine_Scotland_FishDAC_1718 |
Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_1718 |
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 | 2014-11-04 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2014-11-16 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 55000.00 |
Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/resources/uom/gmxUom.xml#m |
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'. | Not Planned |

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The survey will be carried out within an area bounded by approximately 55°N to 56°N and 04° 40’ W to 05° 40’ W. Echointegration will be carried out at 38, 120 and 200 kHz. Trawling operations will be carried out as and when marks are identified. Otoliths will be collected from a sub-sample of the herring and sprat to determine age. The maturity state and presence of Icthyophonus infection will also be recorded. The track will be similar to that carried out during the same survey in 2012 (Figure 1) with modifications being made to target areas where herring are likely to be, based on information obtained from MS Compliance during the survey. The survey will involve following a pre-set survey pattern, at a steaming speed between six and eight knots. The acoustic array will be deployed throughout the survey, unless the vessel is in an area of short transects requiring tight manoeuvrability. |
