| Survey | Investigator | Description |
|---|---|---|
| FR 07/96 [details] |
J.S. Godfrey (CSIRO) including other Pis | Cruise FR 07/96 was undertaken to study freshwater and heat budgets in the Tropical Indian Ocean. Primarily to measure the spatially inhomogeneous freshwater input. An instrumented drifting buoy was deployed at 2 degrees S, 93 degrees E and followed for several days. Radar images (3cm) were recorded at 10 minute intervals through the drift, for use in estimating the rainfall field away from the ship and buoy. Survey methods included boom and meteorological instrumentation, SeaSoar and silverfish deployments, ADCP, CTDs, radiometer measurements and TASCO infrared radiation thermometer tests, current meter recovery and underway instrumentation. Data analysis commenced on board and a draft paper on the results of the budget calculations has been prepared. On this occasion achieved heat budget closure to the desired level of 10 W/m2. |
| FR 03/94 [details] |
J. Church, G. Meyers, F. Boland (CSIRO) including other Pis | Cruise FR 03/94 was undertaken to investigate ocean transport in the Tasman Sea. Cruise objectives were to estimate the volume transport (and its time variability) of the EAC along the east Australian coast and in the Tasman Front using CTD, ADCP and current meter moorings; to determine the large-scale general circulation of the Tasman Sea using patterns of tracers (temperature, salinity, oxygen and nutrients) and of density to estimate geostrophic circulation. Current meter moorings were recovered from near Coffs Harbour (previously deployed on FR 10/89 & FR 11/89). Data and water samples were collected for on board and laboratory analyses. Related Franklin cruises are FR 10/89, FR 11/89, FR 02/90, FR 03/90, FR 10/91, FR 07/92 and FR 07/93. |
| FR 06/92 [details] |
E. Lindstrom (CSIRO), including other Pis | Cruise FR 06/92 forms part of the TOGA-COARE study. The joint Australia-Japan moored intrument array commenced in November 1989 and involves maintaining a current meter mooring on the equator at 147 degrees E. The mooring is part of the TOGA (Tropical Ocean Global Atmosphere) moored observing array for observing currents in the equatorial Pacific Ocean. This cruise was the sixth cycle, marking the end of the CSIRO involvement in the field phase of operation and the end of the third Tokai University surface mooring deployment. The moored current meter array in the New Guinea coastal undercurrent is to directly measure the currents in and transport through Vitiaz Strait, PNG, over an annual cycle. A line of five moorings were deployed across the strait from RV Moana Wave in Frebruary 1992 and the primary task of this cruise was to recover, service and redeploy the moorings, and to collect CTD and ADCP data for use in later interpretation of the moored data. Related cruises are FR 06/91 and FR 07/90. |
| FR 10/91 [details] |
J. Church (CSIRO) | Cruise FR 10/91 was undertaken to study ocean transport in the Tasman and Coral Seas and to collect ground truth data for validation of the ATSR (Along Track Scanning Radiometer). Also testing of the "flying fish" without electronic components and XBT/XCTD tests and calibrations were conducted. Survey methods included ADCP, CTDs, XCTDs, XBTs, underway instrumentation, radiometer, mooring and drifter deployments. Related Franklin cruises are 10/89, 02/90, 10/91, 07/92, 07/93 and 03/94. A cruise report for this voyage is available on-line at http://www.cms.udel.edu/woce/data/reports/pacific/pr11_pr13n_91_church.sum. |
| FR 06/91 [details] |
E. Lindstrom (CSIRO), S. Murray (Louisiana State Univ.) | Cruise Fr 06/91 forms part of the Joint Australia - Japan moored instrument array in the western equatorial Pacific Ocean. The third Australian equatorial mooring was successfully deployed 3 miles west of the Tokai mooring (147 degrees E). The Japanese mooring was not recovered and all equipment is lost. 27 hours of high quality ADCP data were collected at the mooring site. A Tokai University mooring at 2 degrees N, 147 degrees E was recovered successfully and a CTD section was completed along 147 degrees as planned. The moored current meter array in the New Guinea coastal undercurrent was also conducted. The principal aim of this experiment is to directly measure the currents in and transport through Vitiaz Strait, PNG, over an annual cycle. Survey methods included ADCP and CTD sections. Related cruises FR 07/90 and FR 06/92. |
| FR 03/90 [details] |
J. Church (CSIRO) | Cruise FR 03/90 was undertaken to investigate ocean transport in the Tasman Sea. Cruise objectives were to estimate the volume transport (and its time variability) of the EAC along the east Australian coast and in the Tasman Front using CTD, ADCP and current meter moorings; to determine the large-scale general circulation of the Tasman Sea using patterns of tracers (temperature, salinity, oxygen and nutrients) and of density to estimate geostrophic circulation and to determine temporal changes in surface pressure gradient between two points on the Lord Howe Rise, one at 28 degrees S and the other at 38 degrees S using two independent methods (steric height estimate and GEOSAT altimetry). A total of 57 CTD stations and 56 XBTs were completed. ADCP and underway data were continuously recorded and samples were collected for Chlorine-36 analysis from four latitudes and at several depths. Related Franklin cruises are FR 10/89, FR 11/89, FR 02/90, FR 10/91, FR 07/92, FR 07/93 and FR 03/94. A cruise report for this voyage (together with FR 02/90) is available on-line at http://www.cms.udel.edu/woce/data/reports/pacific/pr11_pr13n_90_church.sum . |
