What was the main purpose of the HMS Challenger expedition?
Modern oceanography began with the Challenger Expedition between 1872 and 1876. It was the first expedition organized specifically to gather data on a wide range of ocean features, including ocean temperatures seawater chemistry, currents, marine life, and the geology of the seafloor.
Why was the Challenger Expedition important for oceanography?
Many consider it to be the first true oceanographic expedition because it yielded a wealth of information about the marine environment. Those aboard identified many organisms then new to science, and they gathered data at 362 oceanographic stations on temperature, currents, water chemistry, and ocean floor deposits.
What did the HMS Challenger expedition discover?
Halfway through the journey, in the spring of 1875, Challenger made one of its greatest discoveries: the Mariana Trench, containing the deepest point on Earth. The Mariana Trench is located near Guam, about 1,500 miles east of the Philippines.
What are three reasons to learn the history of oceanography?
Three primary reasons for early civilization to interact with the ocean:
- To obtain food.
- Trade with other cultures.
- To discover new lands.
Which expedition found the deepest part of the ocean?
EXPEDITION OVERVIEW The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.

What did they find in the Challenger Deep?
Discoveries in the Challenge Deep included “vibrantly colorful” rocky outcrops that could be chemical deposits, prawn-like supergiant amphopods, and bottom-dwelling Holothurians, or sea cucumbers.
What caused the Mariana Trench?
The Mariana Trench was formed through a process called subduction. Earth’s crust is made up of comparably thin plates that “float” on the molten rock of the planet’s mantle. This movement creates a trench where the descending oceanic plate drags down the edge of the overriding plate.
What three primary reasons was ocean exploration carried?
When did ocean exploration start?
Ocean exploration begins around 5000 B.C. with the first ocean diving and the first sailing vessels.
What is the deepest point of each ocean?
The deepest place in each ocean are the Molloy Hole in the Fram Strait (Arctic Ocean; 5669 m, 79.137° N/2.817° E), the trench axis of the Puerto Rico Trench (Atlantic Ocean; 8408 m 19.613° N/67.847° W), an unnamed deep in the Java Trench (Indian Ocean; 7290 m, 11.20° S/118.47° E), Challenger Deep in the Mariana Trench …
