PSA Quality Assurance: PS results have been quality assured by Claire Mason (claire.mason@cefas.co.uk) as described in MCZ PSA Quality Statement, available if requested.","CONFIDENTIALITY":"unclassified (open file)","ACCESSUSE_RESTRIC":"unrestricted use, copyright acknowledgement","TERMS_OF_USE":"Available under the Open Government Licence subject to the following acknowledgement accompanying the reproduced Department for Environment, Food and Rural Affairs materials \"Contains Department for Environment, Food and Rural Affairs materials @Crown Copyright [year]\"","TERMS_OF_USE_URL":"http://nationalarchives.gov.uk/doc/open-government-licence/version/3/","EQUIPMENT_START_DATE":"2015-09-07T12:40:57","PHI_MI_5_5":0,"PHI_MI_5_0":0,"PHI_MI_4_5":4.9500000000000002,"PHI_MI_4_0":1.6699999999999999,"PHI_MI_3_5":6.6500000000000004,"PHI_MI_3_0":7.0499999999999998,"PHI_MI_2_5":6.4400000000000004,"PHI_MI_2_0":6.4100000000000001,"PHI_MI_1_5":7.9000000000000004,"PHI_MI_1_0":11.640000000000001,"PHI_4_5":0.040000000000000001,"PHI_5_0":0.040000000000000001,"PHI_5_5":0.050000000000000003,"PHI_6_0":0.059999999999999998,"PHI_6_5":0.050000000000000003,"PHI_7_0":0.050000000000000003,"PHI_7_5":0.050000000000000003,"PHI_8_0":0.050000000000000003,"PHI_8_5":0.029999999999999999,"PHI_9_0":0,"PHI_9_5":0,"PHI_10_0":0,"PHI_10_5":0,"PHI_11_0":0,"PHI_11_5":0,"PHI_12_0":0,"PHI_12_5":0,"PHI_13_0":0,"PHI_13_5":0,"PHI_14_0":0,"PHI_14_5":0}},{"type":"Feature","id":"65445493","properties":{"PSA_DATA_ID":65445493,"ACTIVITY_ID":2345241,"SAMPLE_NAME":"+52+002/3343/GH/1","SAMPLE_ALIAS":"66C","SAMPLE_SOURCE":"Cruise: 2007/10_MEPF","CLIENT":"Marine Aggregate Levy Sustainability Fund","CONTRACTOR":"Gardline","EQUIPMENT_TYPE":"Grab: Hydraulic","EPSG_CODE":4326,"EPSG":"WGS 84","X":2.012,"Y":52.220300000000002,"XY_SOURCE":"DIFFERENTIAL GLOBAL POSITIONING SYSTEM","X_ED50":2.013369,"Y_ED50":52.221115099999999,"X_WGS84":2.012,"Y_WGS84":52.220300000000002,"X_BNG":674121,"Y_BNG":265597,"DEPTH_UNITS":"metres","WATER_DEPTH":39,"DEPTH_TOP":0,"DEPTH_BASE":0,"ANALYSIS_SOURCE":"Particle size analysis of the gravel, sand and mud fractions of offshore samples, these include folk analysis, phi and half-phi sand analysis and carbonate analysis based on folk fractions.","WEIGHT":1983.2,"WEIGHT_UNITS":"grams","GRAV":51.5,"SAND":45.399999999999999,"MUD":3.1000000000000001,"GSM_UNITS":"percent","PHI_0_0":1.4199999999999999,"PHI_1_0":8.5999999999999996,"PHI_2_0":28.010000000000002,"PHI_3_0":6.5099999999999998,"PHI_4_0":0.87,"PHI_UNITS":"percent","ADDITIONAL_INFO":"PHI_4_plus value stored in PHI_4_5 field.","CONFIDENTIALITY":"unclassified (open file)","ACCESSUSE_RESTRIC":"unrestricted use, copyright acknowledgement","TERMS_OF_USE":"Available under the Open Government Licence subject to the following acknowledgement accompanying the reproduced MALSF materials \"Contains Marine Aggregate Levy Sustainability Fund (MALSF) materials ©Crown Copyright [year]\"\r\n","TERMS_OF_USE_URL":"http://nationalarchives.gov.uk/doc/open-government-licence/version/3/","EQUIPMENT_START_DATE":"2007-09-07T00:00:00","PHI_MI_6_0":6.5099999999999998,"PHI_MI_5_5":3.6299999999999999,"PHI_MI_5_0":1.8100000000000001,"PHI_MI_4_0":6.5899999999999999,"PHI_MI_3_5":1.6300000000000001,"PHI_MI_3_0":2.9300000000000002,"PHI_MI_2_5":1.6300000000000001,"PHI_MI_2_0":2.9300000000000002,"PHI_MI_1_5":0.53000000000000003,"PHI_MI_1_0":1.3600000000000001,"PHI_4_5":3.1400000000000001}},{"type":"Feature","id":"65445494","properties":{"PSA_DATA_ID":65445494,"ACTIVITY_ID":2384523,"SAMPLE_NAME":"+50+000/1742/AM/1","SAMPLE_ALIAS":"HGrab 97","SAMPLE_SOURCE":"Cruise: 2007/12_MEPF","CLIENT":"Marine Aggregate Levy Sustainability Fund","CONTRACTOR":"Gardline","EQUIPMENT_TYPE":"Grab: Amon or Hamon","EPSG_CODE":32630,"EPSG":"WGS 84 / UTM zone 30N","X":711941.48999999999,"Y":5618483.6600000001,"XY_SOURCE":"DIFFERENTIAL GLOBAL POSITIONING SYSTEM","X_ED50":0.0014404000000000001,"Y_ED50":50.680422900000003,"X_WGS84":6.9900000000000005e-05,"Y_WGS84":50.679538100000002,"X_BNG":541403,"Y_BNG":88561,"DEPTH_UNITS":"metres","WATER_DEPTH":35.469999999999999,"DEPTH_TOP":0,"DEPTH_BASE":0,"ANALYSIS_SOURCE":"Particle size analysis of the gravel, sand and mud fractions of offshore samples, these include folk analysis, phi and half-phi sand analysis and carbonate analysis based on folk fractions.","WEIGHT":658.60000000000002,"WEIGHT_UNITS":"grams","GRAV":0.42999999999999999,"SAND":99.420000000000002,"MUD":0.14999999999999999,"GSM_UNITS":"percent","PHI_MI_0_5":2.8999999999999999,"PHI_0_0":7.1000000000000005,"PHI_0_5":9.5999999999999996,"PHI_1_0":20.100000000000001,"PHI_1_5":70.200000000000003,"PHI_2_0":373.40000000000003,"PHI_2_5":163.40000000000001,"PHI_3_0":6.1000000000000005,"PHI_3_5":1.3,"PHI_4_0":0.70000000000000007,"PHI_UNITS":"grams","ADDITIONAL_INFO":"PSA depth assumed.
