whats is the H.M.S. Challenger voyage???????

1. What was the main purpose of the H.M.S. Challenger voyage?

2. The voyage of the Challenger was truly an interdisciplinary voyage. There were chemists, biologists, and physicists on board.
Over the course of their 4 years on board, what were the accomplishments of this group of scientists?

3. They used many different types of instruments and tools. List three specific types of tools, or instruments, which were used aboard the vessel and tell what the tool was used to do.

PLEASE HELP ME!!!!! THIS CLASS IS ON FLVS AND IF I FAIL THIS ONE I CANT TAKE ANYMORE HELP!!!!!!! no mean comments or you will be reported.

The Challenger Expedition of 1872-76 was a scientific expedition that made many discoveries to lay the foundation of oceanography.

Prompted by the Scot, Charles Wyville Thomson—of the University of Edinburgh and Merchiston Castle School—the Royal Society of London obtained the use of a ship, HMS Challenger, from the Royal Navy and in 1872 modified it for scientific work, equipping it with separate laboratories for natural history and chemistry.

The ship, commanded by Captain George Nares, sailed from Portsmouth, England, on 21 December 1872.[1] Under the scientific supervision of Thomson himself it travelled nearly 70,000 nautical miles surveying and exploring. The result was the Report Of The Scientific Results of the Exploring Voyage of H.M.S. Challenger during the years 1873-76 which, among many other discoveries, catalogued over 4,000 previously unknown species. John Murray, who supervised the publication, described the report as "the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries".

Challenger returned to Spithead, Hampshire on 24 May 1876, having spent 713 days at sea out of the intervening 1,606.[1] On its 68,890-nautical-mile (127,580 km) journey,[1] it had conducted 492 deep sea soundings, 133 bottom dredges, 151 open water trawls, 263 serial water temperature observations, and discovered about 4717 new species of marine life. Copies of the written records of the Challenger Expedition are now stored in several marine institutions around the UK including the National Oceanography Centre, Southampton and the Dove Marine Laboratory in Cullercoats, Tyne and Wear

Scientific Instruments:

The HMS Challenger crew faced many challenges when they tried to determine temperature. The most commonly used thermometer on the ship was the Miller-Casella mercury thermometer, which was small, difficult to read and susceptible to the effects of pressure. The Challenger also had a piezo (pressure) thermometer and a resistance thermometer. But both of these instruments were fairly new, and the scientists had little experience with them.
