José María Sobral

José María Sobral is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand José María Sobral rather than just read about it. In short: Alférez de Navío José María Sobral (April 14, 1880 – April 14, 1961) was an Argentine explorer, geologist, naval officer and author who rose to prominence by participating in the Swedish Antarctic Expedition (1901–1904) becoming the first Argentine to overwinter in Antarctica. Later he pursued studies at Uppsala University becoming the first Argentine to obtain a geology degree.

Key takeaways

  • José María Sobral belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect José María Sobral to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of José María Sobral from memory before moving on to harder problems.

Reference excerpt

Alférez de Navío José María Sobral (April 14, 1880 – April 14, 1961) was an Argentine explorer, geologist, naval officer and author who rose to prominence by participating in the Swedish Antarctic Expedition (1901–1904) becoming the first Argentine to overwinter in Antarctica. Later he pursued studies at Uppsala University becoming the first Argentine to obtain a geology degree. Sobral worked briefly as ambassador to Norway in 1930 before returning to Argentina to work at YPF.

Biography

Sobral was born in Gualeguaychú, Entre Ríos. He joined the Swedish Antarctic Expedition on the ship Antarctic in Buenos Aires at the end of 1901, when the group headed by Otto Nordenskjöld asked the Argentine Government for supplies, to perform a series of meteorological, biological geological and geodesical studies. The expedition arrived at Snow Hill Island at the Weddell Sea in 1902, where they were to spend one winter. But the ship that was to return to pick them up, the Antarctic, under command of Captain Carl Larsen, was crushed by the ice and sank, leaving the expedition to spend a second winter on Snow Hill Island, with no communication with the mainland or the Antarctic party, which was stranded and spent the winter in rough shelter on Paulet Island. A year later the Argentine corvette Uruguay rescued the survivors, including the Argentine officer. Upon return to Argentina Sobral left the navy and went to Sweden to study geology at the Uppsala University, where he doctored in 1913. In 1906 he married Swedish Elna W. Klingström, with whom he would have 9 children. In 1914 he returned to Argentina, working as National Director of Mining and Hydrology until 1924. In 1930 he was named Argentine consul in Norway, but returned to Argentina a year later to work for Argentine national oil company YPF. He retired in 1935, but continued travelling around Argentina and giving geology lectures until his death in Buenos Aires in 1961, coincidentally on his 81st birthday.

Legacy Sobral wrote a number of books on the Argentine army, Argentina-Chile relations, geology, and his antarctic adventure. He is considered the father of the Argentine Antarctica, a national hero and the first Argentine geologist. The Argentine summer Base Alférez de Navío Sobral was built in 1965 and is located at 81°05' S, 40°00' W, in Edith Ronne Land facing the Filchner Ice Shelf. It supported the Argentine Army's overland expedition to the South Pole in 1965. A stamp bearing Sobral's image and Snow Hill Island is Argentina Scott #1070, 1975. The Argentine Navy patrol boat ARA Alferez Sobral (A-9) was named after him.

Worked examples

Example 1 — a first encounter with José María Sobral

Start with the simplest possible case. Write down what José María Sobral claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to José María Sobral before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about José María Sobral ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of José María Sobral

In research
José María Sobral appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses José María Sobral in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
José María Sobral is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1880 births, 1961 deaths, 20th-century geologists, so understanding it makes those chapters shorter.
In everyday life
Look for José María Sobral outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
