They are dissected by steep-sided valleys produced by at least two glacial stages in the Holocene.  There are over 150 freshwater lakes in the hills, ranging from small ponds less than 1 m deep, to glacial lakes up to 10 ha and 38 m deep.  The lakes are young, with the oldest basins being about 9000 years old. Variations in the characteristics of the lakes reflect deglaciation history, proximity to the continental ice margin and exposure to the ocean.  The main source of the water is snow melt, augmented by sea spray into the more exposed lakes.  The waters are well mixed by katabatic winds.  Most lakes thaw for up to 2 months in summer, but some are permanently frozen.\r\n\r\nThe waters have mainly low conductivity and exceptionally low turbidity, and have near-neutral pH values.  The ionic order is Na+ greater than Mg2+ greater than Ca2+ greater than K+.  This reflects a strong marine influence, with calcium dominating in a very few catchments.\r\n\r\nThe Larsemann Hills were discovered in 1935 by Captain Klarius Mikkelsen in the Thorshavn.  Australian, Chinese and Russian stations were established in the area in the mid-late 1980's.  Law (Australia) was commenced in 1986 when an Apple Hut was unloaded from MV Nella Dan.  A subsequent visit was made during the 1986 winter.  The first Australian scientific expedition visited the area during the 1986-87 austral summer.  Progress Station (Russia) was occupied at the time.  Building of Zhong Shan commenced in January 1989.\r\n\r\n*******************\r\n\r\nSeveral files are associated with this metadata record:\r\n\r\n1) A PDF copy of the original ANARE Research Note\r\n\r\n2) A CSV file containing the data presented in the ANARE Research Note\r\n\r\n3) A shapefile of the lakes presented in the ANARE Research Note\r\n\r\nThe fields in this dataset are:\r\n\r\nlake_id\r\n\r\nlake_name (text)\r\n\r\nlocation (text description)\r\n\r\nlongitude (decimal degrees)\r\n\r\nlatitude (decimal degrees)\r\n\r\naltitude (m)\r\n\r\nlake_area (ha)\r\n\r\ncatchment_area (ha)\r\n\r\nmaximum_depth (m)\r\n\r\ndimensions (m)\r\n\r\ndistance_from_polar_plateau (m)\r\n\r\ndescription (text)\r\n\r\ngeology (text)\r\n\r\nwater_temperature (C)\r\n\r\npH\r\n\r\nwater_conductivity (micro mho/cm)\r\n\r\nEh (reduction potential, mV)\r\n\r\nca_concentration (Ca++, ppm)\r\n\r\nmg_concentration (Mg++, ppm)\r\n\r\nna_concentration (NA+, ppm)\r\n\r\nk_concentration (K+, ppm)\r\n\r\nionic_ratios_na_ca_mg_k (ionic ratio of na:(ca+mg+mk))\r\n\r\nionic_ratios_ca_na_k_mg (ionic ratio of ca:(na+k+mg))\r\n\r\nbottom_sediment_grab_sample (text description of results)\r\n\r\n", "num_resources": 6, "num_tags": 28, "organization": {"id": "3e666ea1-f7c8-4382-a342-0e0bbc88ce9a", "name": "australianantarcticdivision", "title": "Australian Antarctic Division", "type": "organization", "description": "The Australian Antarctic Data Centre (AADC) was established in 1996 to provide long-term management of Australia's Antarctic data, thereby improving the value and impact of our scientific activities. The Data Centre is committed to the free and open exchange of scientific data, consistent with the Antarctic Treaty's position that \"to the greatest extent feasible and practicable scientific observations and results from Antarctica shall be exchanged and made freely available\".\r\n\r\nThe AADC team blends data management and scientific domain expertise with skills in computing, application development, geographic information systems, modelling, and statistical analyses. We work collaboratively with national and international centres, networks, and scientists, providing data management and analysis services as well as actively engaging in scientific research. As Australia's Antarctic Mapping agency, the AADC also supports the logistical operations of the Australian Antarctic Program.\r\n\r\nData held in the AADC are qualified with metadata and discoverable through the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM - http://data.aad.gov.au/aadc/metadata). Some data are also delivered through customised applications on the AADC website - http://data.aad.gov.au. Data delivery systems, where appropriate, use international standards for data exchange and data discovery.\r\n\r\nAADC staff assist in the capture of data at sea and on land, organise satellite
