This survey was undertaken by Cefas as part of the Western English Channel Groundfish Survey using Charter Vessels Bogey 1 and Carhelmar, Qtr 4 (FSS: CARHELMAR); This survey series ran from 1984 to 2013. The aim was to provide fisheries independent abundance indices of all age groups of sole and plaice which are used in assessment working groups to tune the ICES stock assessment and to estimate recruitment. The survey was undertaken annually. Fifty eight trawl stations on the main sole grounds in the English waters of the Western English Channel were fished and sampled. Surveys were carried out on chartered commercial fishing vessels with Cefas staff on board. Survey took place between 26/09/1989 and 03/10/1989 on Carhelmar Equipment used during this survey : - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner PORT - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner STAR Survey operations were undertaken on 57 stations 51 different species were caught on this survey

| 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. | Survey : CHMR 1/89 (part of Western English Channel Groundfish Survey using Charter Vessels Bogey 1 and Carhelmar, Qtr 4 (FSS: CARHELMAR)) |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Carhelmar Beam trawl survey |
| 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. | CEFASe3c8224c-410e-49d4-82b7-c249fc6bc8dd |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS10226 |
| 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 | 1989-09-26 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1989-10-03 |
| 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'. | annually |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A number of changes to the survey grid, sampling procedure and gear have occurred over time and these are documented by Cefas. Data were originally collected and stored in spreadsheets. All Carhelmar data is stored on the Fishing Survey System (FSS). Biological were samples returned to the laboratory fro processing and age determination as required. Data has been extensively quality checked. When the survey was undertaken by the Carhelmar (survey reference prefixed as CHMR) the catch was processed separately by port and starboard beam, but on a few occasions a catch only from the one side was processed. In 2002 and 2004 the survey was undertaken on the Corystes research vessel, (survey reference prefixed as CORY) but only the one beam was used, however this was rigged with the same gear previously used by the Carhelmar. In 2003 both vessels were used. When the survey was conducted on the Carhelmar, the processing of the catch focused on the commercial species. All commercial fish species were measured. Non-commercial species were not always identified and measured. Benthic observations were made in some of the years from the port side beam. Biological age data were collected for sole and plaice.
