Period: 2014-11-10 21:00 to 2014-11-17 02:00 UTC

Duration: 6.21 days

From: Hobart To: Hobart

Region: East coast of Tasmania, shelf break off Maria Island.

Description: RV Investigator trial voyage IN2014_E03. Physical and biological oceanography of the shelf break off Maria Island; And exploration for frontal eddies. This is a trial voyage which took place from Hobart to Hobart from the 11th to 17th November, 2014.
Voyage Objectives.
Introduce key stakeholders and science teams to Investigator, MNF and ASP operations.
Safely undertake as many operations and processes using as much of Investigator's equipment, facilities and capabilities as is possible to train and familiarise MNF staff and visiting science teams
Develop and implement procedures and job hazard assessments(JHAs) for scientific operations - CPR deployments; Triaxus deployments; CTD followed by N70 vertical haul; EZ net; Neuston net, and then simultaneously with EZ net bongo net to 200 m; Rectangular mid water trawl - as a backup for EZ net, and as a large neuston net.
Identify any problems, issues and conflicts and include these in a voyage report.
Collect and process data and samples as for a research voyage to test laboratories, facilities and on board systems.
Regular downloads from OceanCurrent for dynamical oceanography (frontal eddies).
Procedures for fixation with formaldehyde and preservation in alcohol; Chlorophyll extraction to calibrate fluorometers.
Undertake opportunistic testing and checks as per outstanding Specification of Functional Requirements (SFR) list.
Opportunistically collect physical and biological oceanography off the shelf break and explore frontal eddies by gaining meaningful data around Maria Island NRS, and across the 200 m isobath and "nose" of the East Australian Current
