Daily folders (15) of Simrad format (.raw) acoustic data. 15 Echoview format (EV) format analysis files. Excel biological data for 31 pelagic hauls. Objectives: To conduct an acoustic survey to enhance the precision of the survey carried out by FRV Scotia to ultimately provide an estimate of the abundance and distribution of herring in the northern North Sea (ICES area VI and VIa(N)) as part of the ICES International North Sea Herring Acoustic Survey. To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.

Internal code | Internally assigned metadata identifier | 6165 |
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. | HERAS - 0411H - Herring acoustic survey 2011 - North Sea and west of Scotland - MFV Sunbeam |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | HERAS, Herring acoustic survey, charter vessel, MFV Sunbeam, FR487 |
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_1715 |
Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_1715 |
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 | 2011-07-04 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2011-07-27 |
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 |
Abstract | The abstract provides a clear and brief statement of the content of the resource. | Daily folders (15) of Simrad format (.raw) acoustic data. 15 Echoview format (EV) format analysis files.

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | FRV Scotia, which has previously only covered area IV, will be including the area Via(N) north of the Butt of Lewis The survey will be carried out within an area bounded by by 58° 30’N to 62°N and 08°W to 2°E. Echointegration will be carried out at 38, 120 and 200 kHz on a 24 hour-a-day basis. Data from the times between 2300 and 0300 will not be used for stock assessment. Trawling operations will be carried out when the skipper has identified commercially viable marks. Samples of all species caught will be measured for length and weight to establish a length weight relationship. Otoliths will be collected from a sub-sample of the herring to determine age. The maturity state and. presence of Icthyophonus infection will also be recorded. A map of the proposed survey track is given below (Figure 1). The intention is to survey mid way between FRV Scotia transects (dotted line). This will allow an increase in the number of transects sampled in areas of high fish density, as close to being simultaneous with Scotia as possible The survey will involve following a pre-set survey pattern, at a steaming speed of approximately 7 to 10 knots depending on the position of Scotia relative to the charter vessel. A port call will take place at an approximate half way stage in Lerwick; to provide a rest day in accordance with working time directive for a trip of this length |
