Pål Wessel
Pål Wessel (August 31, 1959 – March 26, 2024) pronounced as, and also known as Paul Wessel, was a professor of the Department of Geology and Geophysics at the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa. He taught as a visiting professor at Sydney University in Australia and University of Oslo in Norway. Wessel was a Fellow of the Geological Society of America. Open source mapping tools and data In the 1980s, Wessel and Walter H. F. Smith created Generic Mapping Tools (GMT), an open-source collection of computer software tools for processing and displaying geographic and Cartesian datasets. They later supplemented this with the Global Self-consistent, Hierarchical, High-resolution Shoreline Database (GSHHS) that they constructed from two public domain data sets, the World Data Bank II (WDB), also known as CIA Data Bank, and the World Vector Shoreline (WVS) data set. Geological and geophysical research Areas in which Wes ...

Sarpsborg
Sarpsborg ( or ), historically Borg, is a city and municipality in Viken county, Norway. The administrative centre of the municipality is the city of Sarpsborg. Sarpsborg is part of the fifth largest urban area in Norway when paired with neighbouring Fredrikstad. As of 1 January 2018, according to Statistics Norway these two municipalities have a total population of 136,127 with 55,840 in Sarpsborg and 81,278 in Fredrikstad. Borregaard Industries is, and always has been, the most important industry in the city. The city is also the home of Borg Bryggerier, part of the Hansa Borg Bryggerier, which is Norway's second largest brewery-group. General information Name In Norse times the city was just called ''Borg'' (from ''borg'' which means " castle"). The background for this was the fortification built by Olav Haraldsson (see History section). Later the genitive case of the name of the waterfall ''Sarpr'' ( Sarp Falls) was added, it's unclear how Sarpsborg received thi ...

Hotspot (geology)
In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The alternative plate theory is that the mantle source beneath a hotspot is not anomalously hot, rather the crust above is unusually weak or thin, so that lithospheric extension permits the passive rising of melt from shallow depths. Origin The origins of the concept of hotspots lie in the work of J. Tuzo Wilson, who postulated in 1963 that the formation of the Hawaiian Islands resulted from the slow movement of a tecton ...

Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When he ...

Tasmantid Hotspot
The Tasmantid hotspot is a volcanic hotspot located in the South Pacific Ocean. Due to plate tectonics the hotspot was under different parts of the seabed in the past. It was initially centred under what is now the southern Coral Sea 60 million years ago where the first Tasmantid volcano was created. As the Indo-Australian Plate continued to drift northwards the hotspot was positioned in the northern Tasman Sea 20 million years ago, eventually reaching its current location east of Tasmania in response to ongoing northward plate motion. The erupted volcanics are saturated tholeiitic to transitional alkali-olivine basalt. The northward movement of the Indo-Australian Plate over the last 60 million years coupled with volcanism of the Tasmantid hotspot has resulted in a north-south line of submarine volcanoes called the Tasmantid Seamount Chain. This includes over 10 seamounts, the youngest of which is the seven million year old Gascoyne Seamount. The Tasmantid hot ...

Ontong Java
Ontong Java Atoll or Luangiua, (formerly ''Lord Howe Atoll'', not to be confused with Lord Howe Island) is one of the largest atolls on earth. Geographically it belongs to a scattered group of three atolls which includes nearby Nukumanu Atoll and the wholly submerged Roncador Reef located to the south. Description Administratively Ontong Java belongs to Solomon Islands. As an outlying part of Malaita Province, it forms the northernmost tract of land of this state, over north of Santa Isabel Island. The closest land, however, is Nukumanu Atoll, which lies only due north of Ontong Java's northern tip and, though historically closely related to Ontong Java, is now under the administration of Papua New Guinea. Ontong Java is roughly boot-shaped. The entire size of the atoll is , but there are only of land, spread out over 122 small islands. The islands are mostly low-lying coral formations, the highest elevation being . Approximately 2000 people live on the atoll. There a ...

Samoa
Samoa, officially the Independent State of Samoa; sm, Sāmoa, and until 1997 known as Western Samoa, is a Polynesian island country consisting of two main islands (Savai'i and Upolu); two smaller, inhabited islands (Manono Island, Manono and Apolima); and several smaller, uninhabited islands, including the Aleipata Islands (Nu'utele, Nu'ulua, Fanuatapu and Namua).

The capital city is Apia. The Lapita culture, Lapita people discovered and settled the Samoan Islands around 3,500 years ago. They developed a Samoan language and Samoan culture, Samoan cultural identity.

Tristan
Tristan (Latin/ Brythonic: ''Drustanus''; cy, Trystan), also known as Tristram or Tristain and similar names, is the hero of the legend of Tristan and Iseult. In the legend, he is tasked with escorting the Irish princess Iseult to wed Tristan's uncle, King Mark of Cornwall. Tristan and Iseult accidentally drink a love potion during the journey and fall in love, beginning an adulterous relationship that eventually leads to Tristan's banishment and death. The character's first recorded appearance is in retellings of British mythology from the 12th century by Thomas of Britain and Gottfried von Strassburg, and later in the Prose ''Tristan''. He is featured in Arthurian legends, including the seminal text '' Le Morte d'Arthur'', as a skilled knight and a friend of Lancelot. The historical roots of Tristan are unclear; his association with Cornwall may originate from the Tristan Stone, a 6th-century granite pillar in Cornwall inscribed with the name ''Drustanus'' (a varian ...

Easter Island
Easter Island ( rap, Rapa Nui; es, Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, there is compelling evidence presented in a 2007 study that places their arrival closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. However, land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforest ...
