Metadata: Nutrient data for autumn 2018 and spring 2019 in the Celtic Sea
Abstract:
Nutrient concentration data collected on the RV Cefas Endeavour as part of CEND1718, CEND0319 and CEND04_19, including concentrations of nitrite, nitrate, ammonia, phosphate and silicate. Samples were collected for use in eutrophication assessments and to test the Ferrybox water sampler. Samples were collected using three different methods: ( 1.)Manually from the continuous flow (CF) with mercuric chloride added. ( 2.)Manually from the continuous flow then frozen. ( 3.)Automatically with a water sampler attached to the Ferrybox with mercuric chloride added.

Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 9530 |
| 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. | Nutrient data for autumn 2018 and spring 2019 in the Celtic Sea |
| 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. | CEFAS411ef843-7882-4931-9a70-c4c4cec51bd4 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20365 |
| 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 | 2018-10-06 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2019-04-11 |
| 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 |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | Nutrient concentration data collected on the RV Cefas Endeavour as part of CEND1718, CEND0319 and CEND04_19, including concentrations of nitrite, nitrate, ammonia, phosphate and silicate.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Sample collection methods ( 1.)Manual CF mercuric chloride. Samples were collected from the surface underway system into 1 litre polyethylene bottles. A subsample was filtered through a glass microfibre GF/F filter and the sample was preserved with mercuric chloride to give a final concentration of 20 mg/l. Samples were refrigerated until analysis. ( 2.)Manual CF frozen. Samples were collected directly from the surface underway system into polycarbonate sample bottles and frozen at -20 deg C until analysis. ( 3.)Water sampler mercuric chloride. 150ml water samples were collected from the surface underway system using an automated Cefas Technology Limited water sampler into polyethylene bags which had mercuric chloride added, to give a final concentration of 47 mg/l. Samples were refrigerated until analysis. Sample analysis methods. All samples were sent to the nutrients laboratory at the University of East Anglia for analysis of nutrient concentrations. Samples were analysed on a Skalar continuous flow analyser using the methods detailed by Skalar. |
