6.3 | Purchase diamond saw blades @ 75 m/blade (ARP/CRP).page break |
7. | GPS SURVEYING |
7.1 | Y2K (486+) required for Community Base Station at Cape Roberts Hut. |
7.2 | Real Time Correction Signal - Compatible with any new Vehicle GPS units purchased and RTCM 104 compatable. |
8. | DRILLING |
8.1 | Down hole wire line cutters. Crimp and charge type for wire line. |
8.2 | Modify HQ fishing tool with HQ box? [tool was put in VUW cargo.] |
8.3 | Modify Bull Ring slips? [slips were put in VUW cargo.] |
8.4 | Van Routh plugs for cementing open hole sections to be drilled out later. |
9. | SCIENCE LABORATORY |
9.1 | Paper towels consumed @ 2 packs per 24 hours. |
9.2 | Core splitting blades, allow 80 m of drill hole each (10 × .065 × 5/8 inch). |
9.3 | Replace two hand pump garden sprayers (sea water corrosion and used for other purposes contaminated during decommissioning). |
9.4 | Four Lab-distinctive Tape Measures, 8 m quality/coated for better performance for sea water exposure. |
9.5 | Plastic core splits for boxed core. The core repository has requested that all core be boxed with splits. |
