IN2018_V08     - is a Marine National Facility voyage

Title:- The Balleny mantle plume: key role in Tasmania-Antarctic breakup?

Period:- 2018-12-27 to 2019-01-10

From: Hobart To: Hobart

Region: Southern Ocean; Tasman Sea

Ship :- Investigator (RV) [details]

Project:- The Balleny mantle plume: key role in Tasmania-Antarctic breakup? [details]

Description:- RV Investigator research voyage in2086_v08, titled "The Balleny mantle plume: key role in Tasmania-Antarctic breakup?" Objective 1. Collect seafloor and subseafloor geophysical data. This data will be used: a. To identify seafloor fabric, which will help refine plate reconstructions of the Tasman Seas in areas difficult to constrain from magnetic anomaly lineations alone; b. To obtain comprehensive multibeam and backscatter coverage of the seamounts and their morphology to understand tectonic setting, eruptive style, palaeo-water-depth and sedimentation patterns; c. To assist in dredge site targeting by identifying sediment-free scarps and slopes; d. Sub-bottom profile data will be collected to provide additional context for the nature of the near-surface sediment and geological structure. Objective 2. Dredge volcanic samples from seamounts along the proposed Balleny Seamount chain. Ashore, samples will be: a. Ar/Ar Dated to determine the age and duration of seamount formation; b. Volcanic coherent rocks will be described macroscopically, petrographically and mineralogically to classify and characterise the type volcanism on the seamounts. Comparing the nature and origin of volcanism at different sites may reveal multiple episodes of volcanism or variations in volcanic activity in time and space. c. Volcaniclastic rocks will be described macroscopically, petrographically, mineralogically and include ash morphology descriptions. This work will constrain submarine/subaerial eruption/emplacement and style of transport d. Sedimentary rocks will be described macroscopically, microscopically and petrographically. Additional U-Pb geochronology will be undertaken as will micro- and macro-fossil palaeontology. These analyses can constrain depth, environment, and time of deposition, important for constraining the timing and rate of subsidence.

    Caveat: this event log was authored on the voyage using a standalone logging system called ELOG which has no linkages to any underway or GPS data feeds. For this reason, some positions are unknown and may be resolved using the logged time and the underway dataset for the voyage.

    Maintenance The saw vice becaome unusable when the bolt head washers began to bellow and deform from over tighening. This made it hard to remove the bolt head as the hex was not available to get a socket or anything on because the washers where squashed around it. I begun two options - tap the whashers straight. very hard to access and dificult to use tools in this position. Reviewed the assembly for complete removal: loosened all bolts holding the two main 'ways' to pivot the unit to access the underside bolt issue. This also had little 'gotchas'.... weighting up options. reverted to option 1 and patently straightend the washers to get access to the bolt head. achieved this , used some thicker washers from the engineers store and then re installed all components. Lesson learnt.: Dont over tighten the rock in the vice. make the vice clamp as parallell as possible. Vice clamp mount bolt wASHER NEED TO BE MORE ROBUST THAN A WASHER. the section that the thread pushes onto the vice cheek plate appears to be missing a piece that better connects the two . currently a block of wood is now doing this job. T handle is not that user friendly - ratchcet improved suggest by MAtt.

After the triggering in Ksync had settled in two groups, the SBP120 was set back to group 1 - all OK Unsure of the cause of the initial issue but suspcted to have been a KSync drop-out on the SBP120 (possible aeration from trusters?)
