CHUB02BD-014P (core, piston)
Interval 1 (core, piston)
Description | Gravity core empty; length for piston core recorded as 699cm - Lowering Log indicates it was 849cm; a missing section was noted and continuous depth assignment, 0 to 699cm, adopted. Section 4 is missing. AKA, XIV pg, fourteen roman numeral. We relabel and renumber this piston core using the somewhat shrunken lengths of 1960. Sect1: length 141cm; 2 segments: 0-70cm and 70-141cm; Chocolate brown clays with some tan mottles, nodules at top (~4cm diam) small inclusions at 47.5cm and 69cm (possibly nodules). Sect2: length 145cm; 2 segments, 141-214cm and 214-286cm; brown chocolate clays, some tan mottles with distinct tan zones at 145, 167, 185, 201 and 279cm. Sect3:length 150cm 2 segments; 286-361 cm and 361-436cm; light brown silts with tan mottles to 302cm, 302-324cm area of uniform darker brown clays and inclusions at 328cm. Sect4: although this section was described in 1960, a simple length discrepancy is apparent. The Lowering Log of 1954 measures this section as 127.6cm. The 1960 description was written on a section that measured 147cm after 6 years in which it would certainly have shrunk, not grown in length. Section 4 is therefore assumed to be the missing section and will be assigned the missing depth interval of 436 to 564cm. That depth interval assumes no shrinkage. Section 5: length 147cm,564-638cm and 638cm-711cm; medium brown silts with light mottling. Sect6: length 116cm; 2 segments; 711-769 and 769-827cm; brown to light brown silts and clays, mottled by tan streaks in upper segment; from 759 cm on down, core is more clay like and darker brown color with few mottles. Sum of shrinkage/growth = 22cm. |
