A Lambert Glacier - Amery Ice Shelf series of airborne (Squirrel helicopter and Twin Otter fixed wing) RES and surface elevation profiles were conducted over two summer seasons; 1988/89 and 1989/90. Altogether nearly 10,000 km of various flight paths were undertaken, operating out of Mawson (67.60 S, 62.88 E), Davis (68.58 S, 77.97 E), Dovers (70.22 S, 65.87 E) or Beaver Lake (70.80 S, 68.18 E). More information can be found at the BEDMAP website. The fields in this dataset are: mission_id (unique mission identifier) latitude (decimal degrees) longitude (decimal degrees) ice_thickness (m) surface_elevation (m) water_column_thickness (m) bed_elevation (m)

Please also see the child records of this project for access to data. Attached to this record are the originally supplied datasets for 1997-1998, and also summary files and mooring diagrams supplied in 2012. Taken from the 2008-2009 Progress Report: Progress against objectives: The key to advancing the objective of understanding ocean processes controlling uptake of atmospheric CO2 is the ability to deploy moored autonomous samplers and sensors in Southern Ocean surface waters capable of quantifying seasonal cycles in biological and biogeochemical processes. Our effort in the last 12 months has focused on development of a robust mooring platform to carry these devices. We deployed two different engineering test designs, known as Pulse 5 Heavy and Pulse 5 Light. Both designs survived 6 months in the sea, including wave heights up to 12 meters, while transmitting mooring tensions, mooring accelerations, and GPS positions live to the internet (www.imos.org.au). Following this success we are preparing to deploy the next version of Pulse with scientific instruments to measure temperature, salinity, oxygen, and phytoplankton fluorescence. In addition we deployed a deep ocean mooring with time-series sediment traps to quantify sinking particle fluxes, and in-situ settling columns to determine particle sinking rates. Taken from the 2009/2010 Progress Report: Progress against objectives: Two voyages were awarded by the Australian Marine National Facility to use RV Southern Surveyor to service these Southern Ocean Time Series (SOTS) moorings in the 2009/10 season, and for this reason the shiptime awarded to this project by AAS was not needed and was relinquished. This arrangement will continue in 2010/11 for which the MNF has again awarded two voyages in September 2010 and April 2011. The fieldwork in 2009/10 was very successful: i) the SAZ deep sediment trap mooring was recovered in September 2009 and redeployed for recovery in September 2010. ii) the PULSE biogeochemistry mooring was deployed in September 2009 and functioned beautifully prior to recovery in March 2010 for servicing. It will be redeployed in September 2010. iii) the SOFS Southern Ocean Flux Station mooring was completed and deployed in March 2010 for recovery in April 2011, and redeployment in September 2011.

Metadata record for data from ASAC Project 2519 See the link below for public details on this project. This dataset comprises of floating buoy data collected as part of the ARGO program. All of the data are automatically uploaded to the main ARGO data centre, and can be accessed from there (via the provided URL). Above the map of current float locations on this web page, there are buttons to allow you to access an interactive map, search for floats, and access the data. The Argo floats are programmed to measure temperature and salinity profiles from 2000m to the sea surface every 10 days. When they surface they transmit the profile data, their location, and various engineering parameters to satellite. The data ares put on the Global Telecommunications System (GTS) and are available within 24 hours. Global data centres in the USA and France receive the raw data from the country of origin and also update the data when quality control is performed. Some floats measure other data in addition to temperature and salinity. Dissolved oxygen and current velocity are two other parameters that are measured by a few floats. See the ARGO website for further details about each float (information can be accessed using the WMO (World Meteorological Organisation) numbers provided in the download file). The fields in this dataset are: Launch Date Latitude Longitude ARGO Number WMO Number Webb Number Deployment Order Number More information about the dataset is provided in a readme file as part of the download. Data were last updated in early May, 2014.

With a population of about 2 million pairs macaroni penguins are the most abundant penguin in the HIMI region. These birds feed on mesopelagic fish and, to a lesser extent, mackerel icefish. Despite their great abundance and comparatively proximate links in the food chain to the toothfish fishery, virtually nothing is known about the foraging ecology of macaroni penguins at HIMI. This will identify which regions of the ocean Macaroni penguins use as foraging areas, and in combination with diet studies quantify the potential for competition with fisheries operations in the HIMI region. The data are stored in a csv excel file. The fields in this dataset are: Latitude Longitude Date Direction Range Speed Bearing

Cores from lakes and the shallow marine were taken for investigation of palaeoclimate through proxies such as grain size, TOC, C:N:S and diatoms. The cores have been 14-C dated with some sheel fragments having been analysed using Amino Acid geochronology. The full postglacial record, plus till and pre-glacial sediments, were recovered from two marine cores at 10.3 and 12 m depth in the sediment respectively. These cores are presently (2000) being analysed. Contact the Chief Investgator for queries about these samples or the project, ASAC1071 - 'Palaeoenvironments of the East Antarctic coast between 50E and 120E'. The fields in this dataset are: core number station-employ lake/marine basin latitude longitude water depth (m) date gear recovery (cm) liner (cm) potsdam storage

Locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2004/2005 season. Samples were collected between February and March of 2005. The final dataset will contain information on chlorophyll, carotenoids, coccolithophorids and species identification and counts. Public Summary from the project: This program aims to determine the role of single celled plants, animals, bacteria and viruses in Antarctic waters. We quantify their vital role as food for other organisms, their potential influence in moderating global climate change through absorption of CO2 and production of DMS, and determine their response to effect of climate change.

The productivity of Antarctic waters may be controlled by the amount of iron. Experiments have shown that this is probably the case for phytoplankton but as yet we do not know if iron limits the growth of sea ice algae. This study will assess whether iron limits sea ice algae production and will conduct experiments to work out how these algae use iron. Measurements have been made to determine whether sea ice algae are limited by Fe. Sea ice samples were taken and this spreadsheet refers to those ice cores Columns A-G are self explanatory Column G is the depth in the ice core from the bottom Column H is the chlorophyll concentration in mg Chl m-2 Column I is the phaeophytin concentration in mg m-2 J is the total amount of protein in the sample ng m-2 K is the total amount of the protein flavodoxin ng m-2 L is the total amount of ferrodoxin ng m-2 These last two enable the Fe limitation status to calculated (not completed).
