Description: This is a sediment sample database of over 4000 samples collected to date by INSS, INFOMAR and related projects. They include ADFish, DCU, FEAS, GATEWAYS, IMAGIN, IMES, INIS_HYRDO, JIBS, MESH, SCALLOP, SEAI, UCC. Where available the shapefileshows the results of partical size analysis (PSA) carried out on samples from 2004. PSA is applied to determine the range of sediment sizes contained in the sample which can often reveal an insight about the processes operating in the depositional environment. The results show percentage mud, sand and gravel present in the sample. This analysis is also used to determine if the sample is well or poorly sorted. The database contains information (where available) on:YEAR, SURVEY, VESSEL, SAMPLE_ID, SAMPLER, DATE, TIME, LAT, LONG, DEPTH, RECOVERY, DSCRIPTION, COMMENT, REPORT, MUD, SAND, GRAVEL, PSA_DSCRPT, FOLK_CLASS, SOURCE, IMAGE.
