The CSIRO radiometer was deployed to measure underwater light levels on the Strahan, Marawah transects of FR 10/97. Deployments took place between 10:30 am and 3:00 pm, usually only once daily. Casts were taken near CTD stations.
-
The BSI radiometer was deployed on 12 occasions on the Franklin 7/97 cruise in the area off the mouth of the Sepik River, Papua New Guinea. Deployments took place between 10:30 am and 3:00 pm, usually only once daily. Casts were taken near CTD stations.

Both the CSIRO "Thunderbird" and BSI Radiometers were deployed on the SS 03/96 cruise in the oceanic and shelf waters off south eastern New South Wales and eastern Tasmania.Deployments took place around midday irrespective of position.

Both the CSIRO "Thunderbird" and BSI Radiometers were deployed on the SS 06/96 cruise which was carried out in waters off the east coast of Tasmania, southeastern Victoria and southern New South Wales. Deployments took place around midday irrespective of position.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2014_E03. This is the first trial voyage for the RV Investigator departing Hobart on the 11th November and returning to Hobart on the 17th November 2014. CTD data is collected using a 12/24/36 bottle rosette which can include auxilliary instruments such as: ecotriplet, transmissometer and fluorometers (phytoplankton, oxygen flourescence and turbidity). CTD are sampled at specified stations (refer to map), the system can operate at a maximum depth of 6,000 metres. The 12 bottle carousel CTD is used for trace metal work. The CTD data for this voyage will not be processed. Processing may be arranged upon request.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2015_V01 titled IMOS Southern Ocean time series automated moorings for climate and carbon cycle studies southwest of Tasmania. This was the first research voyage for the RV Investigator departing Hobart on the 21st March and returning to Hobart on the 30th March, 2015. Data for 3 deployments were acquired using the Seabird SBE911 CTD 21, fitted with 24 ten litre bottles on the rosette sampler. The Seabird SBE911 has dual conductivity and temperature sensors. The CTD was additionally fitted with SBE43 dissolved oxygen sensors, Fluorometer, Transmissometer and PAR sensors. These sensors are described in the processing report. The collected data was subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

The Huon Estuary Study was undertaken by CSIRO Marine Research between 1996 and 1998. The Huon Estuary is in South Eastern Tasmania. This record references the CTD data from both the spatial (HES) and the weekly monitoring (CM) surveys of the Huon Estuary Study. For the spatial (HES) surveys this includes the raw, intermediate, processed and calibrated data. The record also references the software used to process this data together with the technical reports written in support of the datasets. Two ctd profilers were utilized during the spatial surveys, their deployment during the spatial surveys is described in a technical report CTD Data From the Spatial Surveys of the Huon Estuary, OMR-121/117. A technical report on the performance of the seabird ctd is Sea-Bird CTD Performance in a Salt-Wedge Estuary, OMR-116/117. For the weekly monitoring (CM) surveys only preliminary processing has been undertaken. A readme_cont_ctd.txt file describes the processing routine followed for the weekly monitoring surveys. This dataset has not been calibrated. There are also other problems with the weekly monitoring ctd data especially in terms of depth registration (see Lineage below). CTD deployment information (not the actual data) is stored in the project database which is described by the 'Huon Estuary Study 1996/1998 - Database' metadata record. A number of CTD's were also deployed during the Physical Snapshot Surveys (see Marlin record 'Huon Estuary Study 1996/1998 - Physical Snapshot Survey Data') These ctd's were quickly deployed, the data was not processed and they form part of the snapshot dataset along with underway data collected on the same day. For these reasons this data are not referenced by this metadata record and does not form part of the HES CTD dataset.

This record describes the data (CTD, Dissolved Oxygen, Transmissometer, PAR, ECO Triplet, Nitrate, Fluorescence and LOPC) collected using the towed TRIAXUS platform on Investigator voyage IN2015_V01, titled: "IMOS Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between March 21 and March 30, 2015 departing from Hobart (TAS) and arriving in Hobart. CTD, Dissolved Oxygen, Transmissometer, PAR, and ECO Triplet have been processed and are made available via the links below. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator Event Voyage IN2015_E03. This is a trial voyage for the RV Investigator departing Hobart on the 16th April and returning to Hobart on the 23rd April, 2015. CTD data is collected using a 12/24/36 bottle rosette which can include auxiliary instruments such as: ecotriplet, transmissometer and fluorometers (phytoplankton, oxygen flourescence and turbidity). CTD are sampled at specified stations (refer to map), the system can operate at a maximum depth of 6,000 metres. The 12 bottle carousel CTD is used for trace metal work. The collected data is subsequently processed and QC'd by the DAP group and archived within the CSIRO Oceans and Atmosphere (O&A) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
