Metadata: 0608H HERAS West coast herring acoustic survey- MFV Chris Andra
Abstract:
Daily folders (17) of Simrad format (.raw) acoustic data. 17 Echoview format (EV) format analysis files. Excel biological data for 24 pelagic hauls. Objectives 1. To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and West of Scotland (ICES area VIa(N) as part of the ICES International North Sea Herring Acoustic Survey. 2. To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.

Internal code | Internally assigned metadata identifier | 6210 |
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. | 0608H HERAS West coast herring acoustic survey- MFV Chris Andra |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | HERAS, North sea herring survey, MFV Chris Andra, FR228 |
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_1725 |
Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_1725 |
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 | 2008-06-27 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2008-07-16 |
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 55°–60°N and 03°–10°W. Echo-integration 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. Fish shoals seen on the echo-sounder will be identified using a pelagic trawl. Trawling operations will be carried out between two and four times per day, and not between 2300 and 0300. 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. Maturity state will also be recorded. Presence of Icthyophonus infection will be recorded. The survey will involve following a pre-set survey pattern, at normal steaming speed (approximately 10 knots). The survey is timed to allow the southern part of the area to be interlaced with the Irish survey, which is due to end in the northern part of their area at the beginning of July. A port call will take place at an approximate half way stage in Ullapool; to provide a rest day in accordance with working time directive for a trip of this length. It is intended to complete the survey in the north-eastern part of the survey area to coincide with the acoustic survey by FRV Scotia in the adjacent area (ICES division IVa). |
