Metadata: Chlorophyll-a concentrations from RRS James Clark Ross Southern Ocean cruise JR20131112 (JR291), austral spring 2013
Abstract:
The dataset comprises chlorophyll-a concentrations from water samples taken during RRS James Clark Ross cruise JR291, from 12/11/2013 - 19/12/2013. The cruise sailed from Stanley, Falklands, and returned to the same port. Samples were taken during transit to Signy Island (South Orkneys), and then up through the Scotia Sea to BAS survey sites P2 and P3 as well as near South Georgia and in the Western Core Box survey area to the north of the island of South Georgia. 170 samples were collected from the ship’s uncontaminated underway supply, with an intake at approximately 6.5 m depth, every two hours during transit periods. 74 samples were collected, using a rosette sampler, from the upper 1000m during CTD (conductivity, temperature and depth probe) deployments. Each 300ml sample was filtered through a 0.8µm pore size, 25mm diameter, MPF300 filter, rinsed with Milli-Q water, placed in an Eppendorf tube and stored at -20°C for later analysis. Samples were extracted in 90 % acetone for 22-24 hours at 4°C and measured on a Trilogy Turner Designs 7200 lab fluorometer calibrated with a pure chlorophyll-a standard (Sigma, UK) and set up following the method of Welschmeyer (1994). Data have not been adjusted for blanks. The data set was from the annual Western Core Box Cruise run by British Antarctic Survey (BAS). Data were collected to support the PhD of Anna Belcher and provide seasonal context for the cruise in terms of the primary production in the surface ocean. Chlorophyll samples were collected by Elena Ceballos-Romero (University of Sevilla), Frédéric Le Moigne (NOC) and Anna Belcher (NOC). Chlorophyll samples were analysed at the National Oceanography centre in Southampton by Anna Belcher from NOC.

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset was created by the organisations with the "originator" role in this metadata record following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for ingestion into one of the schemas of the National Oceanographic Database (NODB). During ingestion BODC undertake quality control, documentation and metadata enhancement procedures appropriate to the type of data. For an overview please see http://www.bodc.ac.uk/about/informationtechnology/dataprocessing_steps/. BODC supply full information about data collection, data processing and data quality with all data requests to enable users to assess data suitability themselves. Instrument(s) used to collect data: fluorometers; CTD. |
