Description: | Monitoring Ocean Change and Variability along 170W from the ice edge to the equator. Principle Investigators also include: Bronte Tilbrook, Lev Bodrossy, Bec Cowley(CSIRO O&A)and Mark Warner, John Bullister (U. Washington, Seattle, WA USA). Scientific objectives: The full suite of key ocean parameters and the deep ocean heat and carbon reservoirs remain poorly measured. This proposal will complete full-depth, high-precision hydrographic, carbon, and tracer measurements, along 170oW from the sea-ice edge to the equator, to monitor and detect ocean variability and change including changes in the carbonate chemistry associated with acidification. These data, together with other observational data and numerical models, will allow for the detection and attribution of ocean change and variability and to assess the impact of the ocean on climate variability. This hydrographic section will monitor ocean change and variability by: 1. Directly measuring the full suite of ocean water properties (temperature, salinity, velocity, nutrients, tracers and ocean mixing) at high vertical and spatial resolution throughout the entire water column and in the deep boundary currents, contributing to the international GO-SHIP program 2. Providing high precision biogeochemical measurements to monitor changes in ocean carbon storage and oxygen concentrations, contributing to the IOCCP international program to monitor the global carbon budget. 3. Directly measure ocean mixing to improve our knowledge of the ocean Meridional Overturning Circulation. 4. Provide high precision baseline data to calibrate the Argo array, XBT program, and other autonomous observations (ocean gliders, moorings and satellites) in the vicinity of the section. 5. Deploy Argo floats for the core mission and contributions to the international SOCCOM project. 6. Obtain side-by-side CTD/XBT data for the assessment of bias errors in XBT measurements. This is an extract from the in2016_v01 voyage plan. This project is affiliated with previous projects "Deep Ocean measurements 2000-2001" and Deep Ocean Time Series Section (DOTSS). These two projects were associated with MNF voyages FR 05/2001 and SS200901 respectively. |

B. Sloyan (CSIRO, O&A) | RV Investigator research voyage in2016_v03. Titled Monitoring Ocean Change and Variability along 170oW from the ice edge to the equator This voyage involves two legs from Hobart to Wellington(NZ) and Wellington(NZ) to Lautoka(Fiji). Voyage objectives of the major project - Monitoring Ocean Change and Variability along 170oW from the ice edge to the equator are: The primary voyage objective is to obtain repeat occupations of the 155 full-depth CTD and Niskin casts along the GO-SHIP P15S section, with chemistry performed on water collected at 36 bottle levels. We will measure temperature, salinity, pressure, oxygen, fluorometry, shear and micro-scale temperature continuously, and the major nutrients, oxygen, salinity, CFC and carbon components discretely via chemical analysis on board. Small amounts of material will be filtered and stored for genomic analyses back on land. CSIRO has completed this line twice before and international groups have completed similar work along lines further east. The work plan and timings are based on these past voyages. Argo float deployments will also be carried out - usually when just leaving a CTD station (SOCCOM floats) or during transit (we may slow the ship speed slightly). These will be over the ship's stern (preferred). Voyage objectives of the supplementary project -Facing the challenges of under-ice for autonomous navigation are: Accurate navigation under both drift and stationary ice is one of the key unanswered questions in polar marine science and engineering. The primary aims of this project are to (1) estimate INS drift and calibration times; and, (2) test the integration of acoustic positioning methods in an INS within a drifting and rotating frame of reference. This project will develop error propagation models at increasing latitudes and test the use of a non-stationary, ship borne acoustic positioning network on a small (<3 m) AUV. Both are critical for robust, accurate and reliable AUV operation under-ice. The primary voyage objective is make measurements of inertial drift during vessel transit and calibration time while the Investigator is on station across as broad a range of latitudes as possible. The way that this will be achieved is that, while the vessel is on station, bench top tests will be conducted for alignment. Then, while moving, tests of inertial drift will be conducted. The student on board will work with the other PIs on board to coordinate timings of these tests but will not disrupt the other work taking place on board. The work plan and timing is based on methodologies established during past voyages. Full details can be found in the in2016_v03 voyage plan. Previous MNF voyages include RV Franklin FR 05/2001 and RV Southern Surveyor SS200901. |
