Review of RRS James Clark Ross icebreaker

RRS James Clark Ross is an UK icebreaking vessel used primarily as a logistics (research / survey / cargo) supply ship serving Antarctica-based scientific stations. The vessel can also be chartered as cruise ship on biological, oceanographic and geophysical themed itineraries. Departures are roundtrip from Port Stanley (Falkland Islands). On Arctic expedition voyages the ship leaves from Portsmouth England (homeported at the Naval Base). RRS stands for "Royal Research Ship".RRS James Clark Ross icebreaker ship

Royal research ships are the UK's merchant navy vessels conducting scientific research for the British Government (HMG). The list of organisations that are allowed to operate RRS vessels includes NERC (abbrev "Natural Environment Research Council"), BAS (abbrev "British Antarctic Survey") and NOC (abbrev "National Oceanography Centre"). However, a warrant from the British monarch is required a vessel to be designated as RRS. The UK's current fleet of Royal Research Ships includes the follwoing vessels (the year built in brackets): RRS James Clark Ross (1990), RRS Ernest Shackleton (1995), RRS James Cook (2007), RRS Discovery (2013) and RRS Sir David Attenborough (2019).RRS James Clark Ross icebreaker ship

This icebreaker ship is named after James Clark Ross (1800-1862) - a British (Royal Navy) officer and an Arctic explorer. He is best known for the Antarctic expedition (1839-1843) during which was charted a huge part of Antarctica's coastline. Also during this expedition were discovered and named Victoria Land, Mount Erebus and Mount Terror (both named after the expedition's ships), Snow Hill Island, Seymour Island, Admiralty Sound. In his honor were named Ross Sea, Ross Ice Shelf and James Ross Island. In 1844, he was knighted by Queen Victoria (1819-1901).
