The current data set contains: Hysplit back-trajectories and IDL reader Trajectories were launched from the SIPEX II ship location every hour at 10m, 500m, 1000m, 1500m, 2000m, 2500m, 3000m, 3500m, 4000m. Three different meteorological reanalyses datasets (ECMWF, GDAS and NCEP were used to generate these 10 day air parcel back-trajectories.

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, phosphate, silicate) data obtained from the First International BIOMASS Experiment (FIBEX) cruise of the Nella Dan, during Jan - Mar 1981. The cruise is the first in a series of six, providing a long term field survey studying krill and other zooplankton. 52 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 14 out of the 52 CTD stations. Casts were made to 2000 m or to near bottom if shallower. The oceanographic sampling was done as a supplement to the krill research program and the nutrient sampling to help interpret phytoplankton distribution and abundance, so sampling location and depth were not necessarily selected according to oceanographic or nutrient related considerations.

Metadata record for data from ASAC Project 1329 See the link below for public details on this project. ---- Public Summary from Project---- The Antarctic Circumpolar Wave is a mode of high latitude variability involving the atmosphere, ocean and sea ice. Some research indicates it has a period of about 5 years but the robustness and persistence has yet to be fully established. This project will examine the nature of the ACW in a long data series, and will determine whether the wave is related to Australian rainfall. In this project, sea ice data were sourced from the National Snow and Ice Data Center (CIRES, University of Colorado, Boulder, CO 80309-0449, USA). The NCEP reanalysis data set was sourced from: NOAA/ National Weather Service, National Centers for Environmental Prediction (5200 Auth Road, Camp Springs, Maryland, 20746 USA). Australian rainfall data were taken from Jones and Weymouth (1997: An Australian Monthly Rainfall Dataset. Technical Report No. 70, Bureau of Meteorology, 19 pp.) compilation and provided digitally by the Bureau of Meteorology. The sea ice concentration data used were for the Antarctic only (the entire Antarctic sea ice domain). Data started in 1978. All data were collected by satellite. A link to a metadata record for these data are available from the URL given below. Two NCEP reanalysis data sets were used in this study. The first was NCEP/NCAR, with 6-hourly data available from 1958 (see the URL provided below for further information). The second was the NCEP/DOE set, with 6-hourly data available from 1979 (see the URL provided below for further information). In this project the following model/analysis was applied: Application of The University of Melbourne cyclone tracking scheme (Simmonds et al., 2003, Monthly Weather Review, 131, 272-288) and a broad range of statistical tests. Brief details are provided in the Summary. See the link for the pdf document for more detailed information. These complex statistical analyses were run over the entire length of the project (2001/02 - 2003/04). They were run on the Sun Workstation cluster in the School of Earth Sciences, The University of Melbourne.

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, nitrite, phosphate, silicate, manganese) data obtained from the Antarctic Division BIOMASS Experiment III (ADBEX III) cruise of the Nella Dan, during Sep - Dec 1985. This cruise is the fifth cruise out of a series of six, conducting a long term field survey on krill and other zooplankton. 50 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 25 of the stations. Casts were made to 2000 m or to near bottom over the continental shelf. The oceanographic and nutrient programs were subordinate to other programs and so the locations of the CTD stations were not always ideal for oceanographic purposes. The fields in this dataset are: pressure temperature salinity volume geopotential samples deviation conductivity

This dataset contains CTD (conductivity, temperature, depth) data obtained from the Australian Antarctic Marine Biological Ecosystem Research (AAMBER) 86/87 cruise of the Nella Dan, during Feb - Apr 1987. This cruise is the last out of a series of six, conducting a long term field survey on krill, fish and zooplankton. 94 CTD casts were taken in the Prydz Bay region, as a supplement to the krill and fish research program. Casts were made to the bottom over the continental shelf, and to either 200 m or 1000 m off the shelf. This dataset is a subset of the whole cruise data. The fields in this dataset are: Pressure Temperature Sigma-T Salinity Geopotential Anomaly Specific volume Anomaly samples deviation conduction

Antarctica is the world's greatest remaining wilderness area. It plays a significant role in many global environmental issues such as wind and water currents and world weather patterns. State of the Environment Reporting: - provides a 'snap-shot' of the status of the Antarctic environment - relies on long-term monitoring of environmental and other variables - allows the detection of trends and patterns, which may be due to natural variability or human-induced (anthropogenic) pressures Why are we interested? State of the Environment Reporting allows us to: - assess the quality of the Antarctic environment - identify threats to the Antarctic environment - monitor the pressures we exert on it and track the impact and efficiency of our activities in the Antarctic. How do we do it? State of the Environment Reporting is based on environmental indicators. Indicators: - are data that summarise physical, chemical, biological or socio-economic factors which best represent the key elements of the environment - are grouped into themes We have developed a web-accessible computer system called SIMR that manages the indicator data, metadata, and custodian information. The system automatically prompts custodians for data and evaluations when required and can produce reports on indicators via the web whenever requested.

This dataset contains CTD (conductivity, temperature, depth) and nutrient (nitrate, nitrite (insignificant concentrations), phosphate, silicate) data obtained from the Second International BIOMASS Experiment (SIBEX II) cruise of the Nella Dan, during January 1985. This cruise is the fourth in a series of six cruises, conducting a long term field survey on krill and other zooplankton. 64 CTD casts were taken in the Prydz Bay region, and nutrient data were collected at 44 of the stations. Casts were made to 1000 m or to near bottom if shallower. Oceanographic and nutrient sampling was done a supplement to the krill research program, and therefore was not always ideal for oceanographic purposes. The fields in this dataset are: cruise name station number date start time ship name station position cast depth sea bottom depth Depth Nitrate Nitrite Phosphate Silicate Manganese (Mn) Pressure Temperature Salinity Sigma-T Specific Volume Anomaly Geopotential Anomaly Number of samples Temperature Deviation Conductivity Deviation This dataset was updated by Angela McGaffin to include a summary excel file. This download file also contains the original datasets.
