ODP Leg 193 Portable Infrared Mineral Analyzer (PIMA) Data Log "Enhance 1,2,3 means two, four, six times the ammount of time spent measuring each 2 nanometer increment to improve the signal to noise ratio. Enhance 0 indicates that no enhancement was used. All samples unless specifically stated otherwise in the comments column were measured using Enhance 2." "All minerals descriptions and mineral names given in the ""Feature analyzed"" and ""Comments"" columns are only tentative as they were given during visual core logging. Therefore these names represent only the initial diagnoses of the minerals present and may change at a later date, subsequent to further analytical analyses on the samples to identify more accurately the minerals present. All measurements were made on the archive half, perferably on a cut surface unless indicated otherwise."
