Metadata: 1980 Eastern Irish Sea Groundfish Survey Catch Data - Silver Star Time Series
Abstract:
A series of groundfish surveys were carried out on the fishing vessel Silver Star from 1976 to 1991 in the eastern Irish Sea. Fishing took place using a Boris Goshawk trawl towed for an hour. This data is from the 3 surveys carried out during 1980. Numbers at length by centimetre of the main commercial fish species are recorded. Station positions by area are recorded.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

All acronyms and abbreviations should be reproduced in full. | 1980 Eastern Irish Sea Groundfish Survey Catch Data - Silver Star Time Series |
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. | CEFAS4695b256-009b-4417-94f0-649e7f1555fa |
Resource Identifier | This is the code assigned by the data owner. | CEFAS2582 |
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 | 1980-03-10 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1980-11-14 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 1000 |
Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
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. | Three cruises were carried out in 1980: - Silver Star 01/80 (10th March - 29th March) Trawling began on 11th March and continued for 5 days until all the groundfish trawling stations along the Welsh coast had been completed. Strong winds prevented work until the 20th, after which 11 out of the intended 14 stations were completed off the Isle of Man working from Douglas. 31 one-hour trawl hauls were carried out in total, all commercial species were measured and otoliths were taken from 406 plaice, 239 whiting, 66 cod, 9 sole. - Silver Star 02/80 (7th June - 28th June) Trawling began at Conwy on the 7th June and continued through until the 11th. The vessel then sailed to Douglas after which four trawl hauls were carried out on the 13th. Increasing NE winds delayed work until 16th, the final trawls were then carried out and completed by the end of the 17th June. 34 one-hour hauls were completed in total, all commercial species were measured and otoliths were taken from 380 plaice, 239 whiting, 59 sole, 35 cod. - Silver Star 04/80 (20th October - 14th November) Trawling commenced from Conwy from 20th to 24th October with only one day being lost for bad weather. Passage was then made to the Isle of Man on the 25th, where due to strong onshore winds the vessel was confined to the inner harbour at Douglas with trawling only being possible on one of the eight days spent there. A return trip was made back to Conwy on the 3rd November, but persistent gales and rough seas allowed only four days work before the cruise ended on the 14th. In total, only 4 stations were worked from the Isle of Man, and 19 of the intended 20 were worked in the Welsh sector. All commercial species were measured and otoliths were taken from 236 plaice, 172 whiting, 148 cod, 58 sole. |
