The maritime Antarctic is characterised by highly variable weather conditions throughout the year, as well as over multi-year periods. The annual variability of weather conditions constitutes an important basis for biological and geographical studies, allowing for the monitoring of the functioning and changes of the geographical environment of the west coast of Admiralty Bay (King George Island, South Shetlands, Antarctica). Year-round meteorological observations (1.2006-12.2006) measured: atmospheric pressure, wind speed and direction, cloud cover, air temperature, relative humidity, total precipitation, snow cover, and Admiralty Bay ice cover.

The turn of the 19th and 20th centuries is a period of intensive research on Antarctica. It was during this period that the South Pole was attained. There were four expeditions which attempted to reach the South Pole: 1. The British National Antarctic Expedition, (1901-1904), on the ship "Discovery", was led by Robert Falcon Scott (1868-1912). The British tried to reach as far south as possible and on December 31, 1902 they reached 82 °17'S. 2. The British Antarctic Expedition (1907-1909) on the ship "Nimrod", led by Ernest Shackleton. On January 9, 1909 the expedition reached 88 °23'S. 3.The Norwegian expedition on the ship "Fram" (1911-1912), led by Roald Amundsen (1872-1928). Amundsen and Olav Bjaaland (1873-1961), Oscar Listing (1871-1936), Helmer Hanssen (1870-1956) and Sverre Hassel (1876-1928) on December 14, 1911 were the first to reach the geographic South Pole. 4. Scott's expedition on the ship "Terra Nova" (1911-1913). The expedition to the South Pole began on November 1, 1911. Scott, Henry R. Bowers (1883-1912), Edgar Evans (1876-1912), Lawrence Oates (1880-1912) and Edward A. Wilson (1872-1912) reached the South Pole on January 17, 1912. They all died on their way back. The participants of all expeditions led to attain the South Pole carried out observations, collected various samples and conducted scientific observations. Afterwards, the collected data and objects were compiled scientifically, sometimes for many years on. During that time, the following, among other, was discovered: the shelf character of Ross Ice Shelf, the Taylor Valley (the first of the snow-free Antarctic "oases"), setting up the basic stratigraphy of the Victoria Land mountains, about 40 thousand various geological and biological specimens were brought home, the latter belonged to more than 2,000 species of plants and animals, among which, more than 400 were species new to science.

This paper presents the scope of geographical research conducted at Arctowski Station during the 30th Polish Antarctic Expedition. The research included meteorological, climatological, geomorphological and glaciological issues. During the expedition, research was conducted on sandur sediments on the outwash plain of Sphinx Glacier, the size of the aeolian transport, intensity of periglacial phenomena, and the way in which environmental conditions are recorded on quartz grains collected on the Admiralty Bay beaches. Detailed measurements of the basic meteorological components were made, geomorphological maps of the outwash plains of Sphinx, Baranowski, and Windy Glaciers were also completed.

The structure of the anther and pollen grain was investigated in an Antarctic plant Deschampsia antarctica Desv. under a confocal microscope (CLSM). The Antarctic hair grass is one of the two native vascular plants growing in Antarctica. The structure of D. antarctica stamens with their short filaments and elongated anthers is typical of the family Poaceae. Microsporogenesis and development of D. antarctica pollen grains proceeds in a way typical of angiosperms from the family Poaceae. Beside the pistil, the hermaphroditic flower has three stamens with numerous pollen grains in pollen loculi. The monoporate and heteropolar pollen grains have a porus located at the distal pole. When observed under the confocal microscope (CLSM), D. antarctica microspores and pollen grains packed tightly inside the microsporangium exhibit strong fluorescence after eosin staining (green fluorescence). The use of calcofluor yielded blue fluorescence of anther endothecial cell walls. The D. antarctica anther endothecium is formed of a single layer of cells, although more than one layer of cells were observed at some sites.

Budowę pylnika i ziaren pyłku badano za pomocą mikroskopu konfokalnego (CLSM) u antarktycznej rośliny Deschampsia antarctica Desv. Śmiałek antarktyczny jest jedną z dwóch rodzimych roślin naczyniowych rosnących na Antarktydzie. Pręciki D. antarctica mają budowę typową dla rodziny Poaceae z krótką nitką i wydłużonymi pylnikami. Mikrosporogeneza i rozwój ziaren pyłku D. antarctica przebiega w sposób typowy dla roślin okrytozalążkowych z rodziny Poaceae. W hermafrodytycznym kwiecie obok słupka występują trzy pręciki, z licznymi ziarnami pyłku w komorach pyłkowych. Ziarna pyłku są jednoporowe i różnobiegunowe, z porusem położonym na biegunie dystalnym. Mikrospory i ziarna pyłku u D. antarctica ułożone ściśle wewnątrz mikrosporangium, obserwowane w mikroskopie konfokalnym (CLSM) wykazują silną fluorescencję po zabarwieniu eozyną (zielona fluorescencja). Po zastosowaniu kalkafluoru ściany komórek endotecjum pylnika fluoryzują na niebiesko. Endotecjum pylnika D. antarctica zbudowane jest z jednej warstwy komórek; w niektórych miejscach obserwowano więcej niż jedną warstwę komórek.

At the occassion of bicentennial of discovery of Antarctica in 1820, the paper addresses the legal framework applicable to this ice-covered continent. Territorial claims of several countries met the rejection of international community. Countries involved in Antarctic polar research gradually established Antarctic Treaty System for its management. Environment protection has become primary concern in contemporary Antarctica. Thanks to its systematic research activities conducted at the Mendel Polar Station, the Czech Republic achieved a privileged position in the system Czech involvement resulted into enactment of Czech Antarctic Law.

Při příležitosti dvousetletého výročí objevení Antarktidy v roce 1820 se věnujeme právnímu rámci tohoto ledem pokrytého světadílu. Územní nároky některých států čelí odmítání mezinárodního společenství. Státy provádějící antarktický polární výzkum postupně vytvořily Antarktický smluvní systém pro její správu. Výzvou doby je ochrana antarktického životního prostředí. Česká republika získala v tomto systému díky soustavnému výzkumu výsadní postavení. České angažmá vyústilo ve vytvoření českého antarktického práva.
