Expedition is a generic term for a journey eg. Polar Expeditions Classification Scheme.
Expedition is also a term for any Path that is not a Crossing, Circumnavigation or Loop and is divided into 4 variants.
An Expedition is also a variant of an Expedition Path.
An Expedition's geographical objective should be named in the label eg North Pole Expedition, Expedition to the Pole of Inaccessibility, etc.
An Expedition starts at a Coastline, Outer Coastline, Inland, Offshore or Mid-Ocean margin and reaches a recognisable point eg. South Pole. Expedition variants:

A Return Expedition starts and ends at the same point or along the same line, reaching a significant feature at its furthermost point. The first half of a Return Expedition must satisfy Expedition Path criteria. A Return Expedition starts and ends at a Coastline, Outer Coastline, Inland, Offshore or Mid-Ocean margin and reaches a recognisable point eg. South Pole Return. Such expeditions usually benefit from self-supplied caches - offloading supplies on the inward leg and recollecting them on the outward leg. Such a strategy still qualifies as Unsupported if all other unsupported criteria are observed. Return Expedition variants:
Examples:
For longest distance record purposes, Return Expeditions are classified differently to one-way journeys and will be titled Longest Return Journey if a record one-way journey is longer. If the Return Expedition is the overall longest distance it will be titled Longest Journey. |

An Alternate Return Expedition starts and ends at at a different Coastline, Outer Coastline, Inland, Offshore or Mid-Ocean margin, reaching a significant point at its furthermost point. The first half of a Return Expedition must satisfy Expedition Path criteria. An Alternate Return South Pole or Alternate Return Antarctica Expedition travels out and back on a different route that is less than 90 degrees of arc between start and end. An Alternate Return North Pole or Alternate Return Arctic Ocean Expedition must include any point on the Northern Pole Line and have less than 90 degrees of arc between start and end. A Greenland Alternate Return Expedition has less than 90 degrees of arc between start and end in relation to the Ice Divide Alternate Return Expedition variants:

A Reverse Expedition starts at the North or South Pole or other significant feature and ends at a Coastline, Outer Coastline, Inland, Offshore or Mid-Ocean margin. Reverse Expedition variants:
