However, the previous pole location disregards the Gulf of Ob as part of the oceans, and a 2007 study proposes two other locations as the ones farther from any ocean (within the uncertainty of coastline definition): EPIA1 and EPIA2 , located respectively at 2,510±10 km (1560±6 mi) and 2,514±7 km (1,562±4 mi) from the oceans. These points lie in a close triangle about the Dzungarian Gate, a significant historical gateway to migration between the East and West. EPIA2 is located near a settlement called K̂as K̂îr Su in a region named K̂îzîlk̂um (قىزىلقۇم) in the Karamgay Township, Burultokay County.
