This could be because newer QGIS version might use a long time to load the NSIDC Sea ice concentration raster files in the project. Until the next version of Quantarctica where we will prepare new raster files, the temporary solution is either to use an older version of QGIS, or remove these raster files from the project. In the latter case, let QGIS keep loading the Quantarctica project file although it seems to have frozen. It might take five or ten minutes, but then it should complete loading. At that point, locate the Sea ice group in the Layers panel in QGIS, expand it, and select and mark all the NSIDC Sea ice concentration February raster layers so that they are highlighted, right-click one of them, and select \u201cRemove Layer\u2026\u201d. Do the same with the September raster layers, and save the project as a new project, e.g., \u201cQuantarctica32_NoSeaIceConcentration\u201d or similar. From now on, the project should load more promptly.<\/p>\n<\/div><\/div><br \/>\n<section  class='av_textblock_section av-22ufi4j-8e44d883f92395683ef762013f48646d '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h2>Download<\/h2>\n<div id=\"content-download\" class=\"site-content clr\">\n<article class=\"single-page-article clr\">\n<div class=\"entry clr\">\n<p class=\"ingress\">See the&nbsp;<a href=\"https:\/\/tryggve.npolar.no\/WEB\/quantarctica\/Quantarctica_GetStarted.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Quantarctica user manual<\/a> (PDF 1 MB) for installation details and how to optimize QGIS for use with Quantarctica.

The SCAR Standing Committee on Antarctic Geographic Information (SC-AGI) co-ordinates the provision of a geographic reference for scientific activities in Antarctica and the dissemination of Antarctic geographic information. The SCAR Composite Gazetteer of Antarctica is an activity conducted in this framework. In 1992 the SCAR Working Group on Geodesy and Geographic Information (WG-GGI), during the XXII SCAR meeting in Bariloche, recognized the need for a composite gazetteer of Antarctica to bring some order to the complex toponymy of Antarctica. The goal of the work programme which evolved from that discussion was to provide the scientific community with two products: 1. compilation of all existing geographic names of Antarctica and 2. a set of guidelines to be followed when proposing new names and when selecting one name from a list of synonyms for a given feature. Because Antarctica does not fall under the sovereignty of any one nation this particular continent is similar, in many respects, to the oceans. In general every country has a recognized body which approves the names of geographic features in the country and also has the power to enforce their use. For Antarctica, however, there is no such single naming authority. Individual countries are responsible for their national policy on, and authorisation and use of, Antarctic names.<\/p>\n<p><!-- Italic text (article reference) --><\/p>\n<p class=\"p-text-em\">SCAR Secretariat (1992, updated 2014 and 2017).

Such information is essential in order to inform the conservation actions needed to protect them against the range of threats identified in Antarctica. These include direct disturbance by visitors, disturbance by aircraft or vehicles, exposure to pollutants, ingestion of or fouling by marine debris, competition for prey from fisheries, accidental by-catch on fishing lines or in nets, introduction of disease from other parts of the world and climate change. Recent analyses have identified 204 Important Bird Areas (IBAs) in Antarctica, for all of which detailed site accounts have been compiled. Sites were identified using internationally agreed criteria that have been applied in 200 countries over the past 35 years. The compiled list of IBAs provides a baseline against which change can be measured and conservation actions considered.<\/p>\n<p><!-- Italic text (article reference) --><\/p>\n<p class=\"p-text-em\">Colin Harris, Lincoln Fishpool, Ben Lascelles, Katherina Lorenz, 2016.

H.<\/p>\n<p class=\"p-text\">This dataset uses a global seismic model of the crust and upper mantle to extrapolate existing heat-flux measurements to areas where there are few data, using a \u201cstructural similarity function\u201d. The original data are gridded on a geographic (lat-lon) grid, so when they are projected to a polar stereographic projection, this creates problems in gridding straight to 5 km resolution, due to the directionality of the points used in the interpolation procedure. The gridding introduces elongated features which are not present in the original data. The effective resolution of the data (in latitude anyway) is 100 km. Therefore the data were first gridded on to a 100 km grid using spline interpolation. The 100 km grid points were then reinterpolated, again using spline interpolation, onto the 5 km grid. This reduces the elongated features whilst retaining most of the detail in the original dataset. The data unit is mWm-2.<\/p>\n<p><!-- Italic text (article reference) --><\/p>\n<p class=\"p-text-em\">Shapiro, N. M. and Ritzwoller, M.

Ice thickness DEM was formed from the available radio-echo sounding (RES) data using the &#8216;Topo to Raster&#8217; function in ArcGIS. The RES data used in this study were compiled from four main sources which are (1) Scott Polar Research Institute (SPRI) survey collected during several campaigns in the 1970s (Drewry, 1983), (2) British Antarctic Survey (BAS) airborne radar survey conducted during the austal summer 2006\/07 (GRADES\/IMAGE) (Ashmore et al., 2014), (3) BAS airborne survey accomplished during the Institute and M\u00f6ller Antarctic Funding Initiative (IMAFI) in 2010\/2011 (Ross et al., 2012) and (4) Center for the Remote Sensing of Ice Sheet (CReSIS) data during the NASA Operation IceBridge (OIB) programme in 2012, 2014 and 2016 (Gogineni, 2012).

The temperatures represent an average for the period 2000-2017 at 1km2 spatial resolution. The dataset is a product of a TTOP (temperature at the top of the permafrost) equilibrium model that was driven by remotely sensed land surface temperatures (MODIS LST). Gap-filling was performed by downscaled ERA-Interim and ERA-5 climate reanalysis data, which were also used to estimate snow cover. The results were validated against in situ-measured ground temperatures from 40 permafrost boreholes, and the resulting root-mean-square error was 1.9\u2009\u00b0C.<\/p>\n<p><strong>Publication citation<\/strong>: Obu, J., Westermann, S., Vieira, G., Abramov, A., Balks, M.

Inside a QGIS instance of Quantarctica 3.2, right-click somewhere in the blank part of the data layer panel, and select Paste Layer\/Group.
