Other constraints

Either: (i) the dataset is made freely available, e.g. via the Internet, for a restricted category of use (e.g. educational use only); or (ii) the dataset has not been formally approved by BGS for access and use by external clients under licence, but its use may be permitted under alternative formal arrangements; or (iii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted in order to determine the permitted usage of the dataset. Refer to the BGS staff member responsible for the creation of the dataset if further advice is required. He / she should be familiar with the composition of the dataset, particularly with regard to 3rd party IPR contained in it, and any resultant use restrictions. This staff member should revert to the IPR Section ( ipr@bgs.ac.uk) for advice, should the position not be clear.

Statement

Bulk rock or soil samples were crushed either using a ball mill, or agate pestle and mortar. Approximately 1g of sample was accurately weighted and then leached by the following methods in sequence using an end over end shaker. The overall sequence was a modified 6-step sequential extraction based on the BCR method (Rauret et al., 1999) and a scheme from Ruttenberg (1992) specifically designed for phosphorus extraction from marine sediments 1. Ion exchangeable fraction: 40ml of 1M MgCl2 at pH7 for 1 hour. 2. Acid soluble fraction: 40ml 0.11mol/L acetic acid for 16 hours. 3. Reducible fraction: 45ml 0.3M Na citrate buffered with 1M NaHCO3 at pH 7.6, with 1.125g of Na-dithionite for 8 hours. 4. Reactive (authigenic) phosphate: 40ml 1M Na-acetate buffered to pH4 with acetic acid for 6 hours. 5. Resistant (detrital) phosphate: 40ml 1M HCl for 16 hours. 6. Oxidisable: 10ml 8.8M hydrogen peroxide heated to 22°C for 1 hour, then repeated. Heated to evaporation, then 50ml 1M ammonium acetate buffered to pH2 with HNO3 for 16 hours. After each stage the samples was centrifuged to separate the leachate, the leachate diluted with 2% HNO3, and the solid washed with deionised water and then dried prior to the next step. Solution analyses were conducted using an Agilent 7900 ICP-MS at the University of Brighton, using online addition of 100ug/L rhenium solution as internal standard. The data was calibrated against calibration curves constructed with a calibration blank and Agilent multi-element standards diluted to different concentrations. The relative standard deviation was <10% for all elements analysed.
