Theta
Theta (, ; uppercase: Θ or ; lowercase: θ or ; grc, ''thē̂ta'' ; Modern: ''thī́ta'' ) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth . In the system of Greek numerals, it has a value of 9. Greek In Ancient Greek, θ represented the aspirated voiceless dental plosive , but in Modern Greek it represents the voiceless dental fricative . Forms In its archaic form, θ was written as a cross within a circle (as in the Etruscan or ), and later, as a line or point in circle ( or ). The cursive form was retained by Unicode as , separate from . (There is also ). For the purpose of writing Greek text, the two can be font variants of a single character, but are also used as distinct symbols in technical and mathematical contexts. Extensive lists of examples follow below at Mathematics and Science. is also common in biblical and theological usage e.g. instead of πρόθεσις (means placing in public or laying out a corpse). ...

Melchior Islands
The Melchior Islands are a group of many low, ice-covered islands lying near the center of Dallmann Bay in the Palmer Archipelago, Antarctica. They were first seen but left unnamed by a German expedition under Eduard Dallmann, 1873–74. The islands were resighted and roughly charted by the Third French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05. Charcot named what he believed to be the large easternmost island in the group "Île Melchior" after Vice Admiral Jules Melchior of the French Navy, but later surveys proved Charcot's Île Melchior to be two islands, now called Eta Island and Omega Island. The name Melchior Islands has since become established for the whole island group now described, of which Eta Island and Omega Island form the eastern part, while the Sigma Islands mark the northern limit of the islands. The group was roughly surveyed in 1927 by Discovery Investigations personnel in the ''RRS Discovery'', and was resurveyed by Argentine expeditio ...

Dallmann Bay
Dallmann Bay is a bay lying between Brabant Island and Anvers Island, connected to Gerlache Strait by the Schollaert Channel, in the Palmer Archipelago. It was discovered and first roughly charted in 1874 by the German whaler Captain Eduard Dallmann, and was named for Dallmann by the Society for Polar Navigation, Hamburg, which sponsored Dallmann's Antarctic exploration. It was later charted by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). Life Jean-Ba ....

Palmer Archipelago
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898. He named it Archipelago Palmer for American Captain Nathaniel Palmer, who navigated these waters in 1820.

Kappa Island
Kappa Island () is an island, nearly long, lying immediately south of Beta Island and close east of the Theta Islands in the Melchior Islands of the Palmer Archipelago, Antarctica. The name, derived from kappa, the tenth letter of the Greek alphabet, probably was given by Discovery Investigations The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean.

Discovery Investigations
The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean. They were funded by the British Colonial Office and organised by the Discovery Committee in London, which was formed in 1918. They were intended to provide the scientific background to stock management of the commercial Antarctic whale fishery. The work of the Investigations contributed hugely to our knowledge of the whales, the krill they fed on, and the oceanography of their habitat, while charting the local topography, including Atherton Peak. The investigations continued until 1951, with the final report being published in 1980. Laboratory Shore-based work on South Georgia took place in the marine laboratory, Discovery House, built in 1925 at King Edward Point and occupied until 1931. The scientists lived and worked in the building, travelling half a mile or so across King Edward Cove to the whaling station at Grytviken to work on w ...
