Metadata: Southern Ocean Freshwater Flux Field
Abstract:
The dataset comprises a derived freshwater flux field for the Southern Ocean. This flux field is the rate of freshwater (m^-3 s^-1) entering each point of a grid covering the Southern Ocean, divided by the surface area (m^-2) represented by each grid point, which gives a flux (m s^-1) at each grid point. It was produced using up-to-date freshwater data from ice shelves, icebergs, and rivers over the period 2010-2015 and integrated over a surface encompassing Antarctica and surrounding waters. These data are intended for use in the Southern Ocean State Estimate (SOSE) iteration of the MIT General Circulation Model (MITgcm), but can be adapted for use on a different grid or model. The flux data are in units of m yr-1, on a 2160x320 grid. MATLAB scripts and tables of runoff data are available and show how the field was produced, how the data can be used and how different data can produce the field for a different grid. The field was created to update the accuracy of the freshwater input to a model based on SOSE, and to stabilise it with respect to the formation of open-ocean polynyas. This field was produced by Mark Hammond under the supervision of Dr Dan Jones at the British Antarctic Survey.

Internal code | Internally assigned metadata identifier | 8408 |
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. | Southern Ocean Freshwater Flux Field |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | British Oceanographic Data Centre record 1048SouthernOcean_FreshwaterFlux |
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. | 4afcb51b173e5fd7ba9e955b1f143224 |
Resource Identifier | This is the code assigned by the data owner. | EDMED6546 |
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 | 2010-01-01 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2015-12-31 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
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'. | asNeeded |

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 procedures and model. The data were then provided to the British Oceanographic Data Centre (BODC) for archival and discoverability. This record will include any updates to the data as and when they occur. The originator supplies both documentation and software through the link in this metadata record. No data quality or data processing procedures were applied by BODC. |
