The GEOTRACES Intermediate Data Product 2017
No full textThe GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 25 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017
The GEOTRACES Intermediate Data Product 2014
No full textThe GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes (TEIs) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a strongly inter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 covers the Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at cross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet, netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering. Metadata about data originators, analytical methods and original publications related to the data are linked to the data in an easily accessible way. The eGEOTRACES Electronic Atlasis the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data from many cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition, the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes, as well as for making inferences about controlling processes

Introduction to the French GEOTRACES North Atlantic transect (GA01): GEOVIDE cruise
No full text© 2018 Author(s). The GEOVIDE cruise, a collaborative project within the framework of the international GEOTRACES programme, was conducted along the French-led section in the North Atlantic Ocean (Section GA01), between 15 May and 30 June 2014. In this special issue (https://www.biogeosciences.net/special-issue900.html), results from GEOVIDE, including physical oceanography and trace element and isotope cyclings, are presented among 18 articles. Here, the scientific context, project objectives, and scientific strategy of GEOVIDE are provided, along with an overview of the main results from the articles published in the special issue
A process evaluation of the City of Cape Town Business Support Voucher Programme
No full textIncludes bibliographical references (leaves 74-78).This dissertation focuses on a process evaluation of the City of Cape Town (CoCT) Business Support Voucher Programme (BSVP) which assessed whether this programme was implemented as intended. The BSVP aims to provide access to quality business support services and products to entrepreneurs in order to empower them to develop and grow their businesses. The target beneficiaries of the BSVP are the over 35 year old age group (including women, youth and the disabled) who are potential or start-up entrepreneurs or who own/run existing small businesses. A service utilisation flow chart was used to review the services provided by the allocating agents and the business development service providers. Data providers included the project sponsors, the implementation agent, the allocating agents and a convenience sample of beneficiaries and service providers. Additional materials used included check lists during site visits and a review of records. The findings suggested that whilst the programme was largely implemented as planned, there could be improvements to the definition of the programme targets, the consistency of the implementation across the programme and putting monitoring and reporting systems in place. The dissertation includes selected recommendations for implementation improvement, sustainability and future outcomes and impacts

GEOTRACES Intermediate Data Product (IDP) Download Agreement
The GEOTRACES programme is keen to ensure that the very significant effort and expertise involved in making trace-element and isotope measurements is acknowledged as fully as possibly in subsequent publications.
Users of the GEOTRACES Intermediate Data Product are expected to abide to the following rules regarding citation
To the greatest extent possible, please cite all relevant publications from researchers that made the measurements you use in your work. Details of publications that should be cited are provided point-by-point in the IDP dataset (in the ODV and ASCII versions) and will be updated on the online database as new papers are published. Where your research deals particularly with data measured by a single group of data originators, you are invited to please contact that group to discuss your work prior to publication and jointly consider the synergy and mutual benefit of co-authorship where appropriate.
Where other constraints prevent citation of all relevant publications, for instance where there is a journal limitation on the maximum number of publications that can be cited, or if the dataset is only used in a minor supportive way, please cite the data compilation itself (as below). In such cases, also please cite any original individual papers that you rely on particularly heavily for your research and interpretations.
Where using data from the IDP2017 product in your publication, please cite the data compilation as: Schlitzer, R., Anderson, R. F., Masferrer Dodas, E, et al., The GEOTRACES Intermediate Data Product 2017, Chem. Geol. (2018), https://doi.org/10.1016/j.chemgeo.2018.05.040 .
Where using data from the IDP2014 product in your publication, please cite the data compilation as: Mawji, E., et al., The GEOTRACES Intermediate Data Product 2014, Mar. Chem. (2015), http://dx.doi.org/10.1016/j.marchem.2015.04.005 .
