Baltic FleetThe Baltic Fleet (Baltiyskiy flot) is the fleet of the Russian Navy in the Baltic Sea. Established 18 May 1703, under Tsar Peter the Great as part of the Imperial Russian Navy, the Baltic Fleet is the oldest Russian fleet. In 1918, the fleet was inherited by the Russian SFSR which then founded the Soviet Union in 1922, where it was eventually known as the Twice Red Banner Baltic Fleet as part of the Soviet Navy, as during this period it gained the two awards of the Order of the Red Banner.
Reference materials for stable isotope analysisIsotopic reference materials are compounds (solids, liquids, gasses) with well-defined isotopic compositions and are the ultimate sources of accuracy in mass spectrometric measurements of isotope ratios. Isotopic references are used because mass spectrometers are highly fractionating. As a result, the isotopic ratio that the instrument measures can be very different from that in the sample's measurement. Moreover, the degree of instrument fractionation changes during measurement, often on a timescale shorter than the measurement's duration, and can depend on the characteristics of the sample itself.
LakeA lake is a naturally occurring, relatively large body of water localized in a basin surrounded by dry land. A lake generally has a slower-moving flow than the inflow or outflow stream(s) that serve to feed or drain it. Lakes lie completely on land and are separate from the ocean, although, like the much larger oceans, they form part of the Earth's water cycle by serving as large standing pools of storage water. Most lakes are freshwater and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater.
Climate variability and changeClimate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. Climate change may refer to any time in Earth's history, but the term is now commonly used to describe contemporary climate change. Since the Industrial Revolution, the climate has increasingly been affected by human activities.
Baltic Finnic peoplesThe Baltic Finnic or Balto-Finnic peoples, also referred to as the Baltic Sea Finns, Baltic Finns, sometimes Western Finnic and often simply as the Finnic peoples, are the peoples inhabiting the Baltic Sea region in Northern and Eastern Europe who speak Finnic languages. They include the Finns, Estonians (including Võros and Setos), Karelians (including Ludes and Livvi), Veps, Izhorians, Votes, and Livonians. In some cases the Kvens, Ingrians, Tornedalians and speakers of Meänkieli are considered separate from the Finns.
Subglacial lakeA subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where gravitational pressure decreases the pressure melting point of ice. Over time, the overlying ice gradually melts at a rate of a few millimeters per year. Meltwater flows from regions of high to low hydraulic pressure under the ice and pools, creating a body of liquid water that can be isolated from the external environment for millions of years.
DustDust is made of fine particles of solid matter. On Earth, it generally consists of atmospheric particulates (particles in the atmosphere) that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. The rest, and in offices, and other human environments is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment.
Glacial lakeA glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep.
BaltsThe Balts or Baltic peoples (baltai, balti) are an ethno-linguistic group of peoples who speak the Baltic languages of the Balto-Slavic branch of the Indo-European languages. One of the features of Baltic languages is the number of conservative or archaic features retained. Among the Baltic peoples are modern-day Lithuanians and Latvians (including Latgalians) — all Eastern Balts — as well as the Old Prussians, Yotvingians and Galindians — the Western Balts — whose languages and cultures are now extinct.
PolandPoland, officially the Republic of Poland, is a country in Central Europe. It is divided into 16 administrative provinces called voivodeships, covering an area of . Poland has a population of 38 million and is the fifth-most populous member state of the European Union. Warsaw is the nation's capital and largest metropolis. Other major cities include Kraków, Gdańsk, Wrocław, Katowice, Łódź, Poznań, Szczecin and Lublin.
