Metadata: 2015 - 2018 Marine Biological Association of the United Kingdom (MBA) Western English Channel standard haul demersal fish survey data
Abstract:
Time series data of demersal fish populations in the Western English Channel sampled using a large otter trawl (15m headline) by the Marine Biological Association of the United Kingdom from 2015-2018. This data set contains vertebrate data from 108 trawls. For each trawl, the entire catch was identified to species level. This dataset contains abundance, length, weight and disk width (if applicable) measurements. This dataset contains consistent sex data for elasmobranchs. Invertebrate abundance data was also collected on each survey and is available on request to MBASepia@mba.ac.uk. These data include high confidence cephalopod, scallop and large crab abundance as well as counts of other invertebrates including other crustaceans and echinoderms.
Data holder:
Marine Biological Association of the United Kingdom
Use constraints:
open access; Unpublished data (such as that excluded data mentioned in the lineage field) can be requested via MBASepia@mba.ac.uk

| Internal code | Internally assigned metadata identifier | 113 |
| 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. | 2015 - 2018 Marine Biological Association of the United Kingdom (MBA) Western English Channel standard haul demersal fish survey data |
| 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. | 0370af22f970a98e2a5fcc79d5dd05b1 |
| Resource Identifier | This is the code assigned by the data owner. | MBA_StandardHaul_DT0001 |
| 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 | 2015-01-21 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2018-09-13 |
| Vertical extent (min) | A positive or negative decimal number, for example, the shallowest depth recorded if subtidal, or, if intertidal, the lowest point recorded. | -20.0000 |
| Vertical extent (max) | A positive or negative decimal number, for example, the deepest depth recorded if subtidal, or, if intertidal, the highest point recorded. | -80.0000 |
| Vertical extent reference | This descibes the vertical coordinate reference system as referred to in the EPSG register of geodetic parameters. (epsg-registry.org) | urn:ogc:def:crs:EPSG::5861 |

| 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'. | unknown |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | Time series data of demersal fish populations in the Western English Channel sampled using a large otter trawl (15m headline) by the Marine Biological Association of the United Kingdom from 2015-2018.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This 4-year dataset belongs to a parent data-series of standard haul demersal fish survey time series data titled '1913 - Ongoing Marine Biological Association of the United Kingdom (MBA) Western English Channel standard haul demersal fish time series survey data' with resource ID 'MBAStandardHaulSE01'. Seven research vessels have been used over the course of the time series with comparable gear i.e. an ~15m headline otter trawl with a small mesh cod-end or a cod end liner of mesh size 20mm. There is high confidence in this dataset. Data is subject to quality checking of 10% of digitised data against paper records. Since 2018, taxonomic identification has been validated through the NMBAQC scheme. If there is any question of confidence of taxonomic identification of a species then a more general taxonomic level is used to describe these specimens (typically genus). Data of lower confidence levels, including invertebrate records and sex data for non-elasmobranchs, has been excluded from this data set but can be requested via MBASepia@mba.ac.uk, these data include high confidence cephalopod, scallop and large crab abundance as well as counts of other invertebrates including other crustaceans and echinoderms. Record Types (see SpeciesNotes in taxon form) describe the measurements that were carried out for the sample and/or individuals: Individuals - (Each individual caught has been weighed, measured and counted), Abundance / Weight - (All individuals landed have been weighed and counted as a whole, not individually), Sub-sample (Abundance) - (Measured total weight off all landed individuals, and from this estimated total abundance) and Sub-sample (Weight) - (Counted the total abundance of all landed individuals and from this estimated the total weight). Please note that where an unknown weight occurred, the database auto-filled the blank entry with a value of 1. Therefore if weights are from a record types of 'Abundance/Weight' and 'Subsample Abundance' with values of 1, these are assumed to be an auto-filled value and have been changed to unknown within this data set. Where an 'Individual Weight' or a Wet weight biomass which is Record Type 'individuals' and abundance of 1, contain a value of 1, this is assumed to be correct and has not been changed in this data set, but should be treated as correct under the data user's discretion. If any sensitive species or biotope records are present within this dataset, they will have been removed. If you wish to request access to sensitive species records, please contact the metadata contact. The UK Sensitive Species list has been agreed by UK statutory bodies and relevant experts. It can be viewed here https://docs.nbnatlas.org/sensitive-species-list/. Please note sensitive species lists can vary across the UK. |
