Internal code | Internally assigned metadata identifier | 6330 |
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. | FishDAC - Mackerel Egg Survey (Scotland) |
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_884 |
Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_884 |
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 | 1977-01-01 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-11-07 |
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'. | unknown |
Abstract | The abstract provides a clear and brief statement of the content of the resource. | This is the Scottish component of the ICES-coordinated triennial mackerel and horse mackerel egg survey (1977-to date). See also the individual cruise records. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Ichthyoplankton are sampled via a stratified, systematic sampling design using double-oblique tows of a Gulf VII sampler (or earlier variant depending on the survey year). Egg densities are measured per unit volume of seawater filtered and integrated to the density per unit area. Trawl haul samples are taken to provide data on the biological characteristics of spawning fish and the sex ratio of the sampled population. Ovarian samples are collected to calculate fecundity (also accounting for atresia of eggs). Raised estimates of annual egg production and the average fecundity per unit weight of females is used to calculate spawning biomass. Temperature and salinity data are collected to characterise the spawning fish environment. |
