The Bransfield Basin is a Back-arc rift basin located off the Northern tip of the Antarctic Peninsula. The basin lies within a Northeast and Southwest trending strait that separates the peninsula from the nearby South Shetland Islands to the Northwest.[1]The basin extends for more than 500 kilometers from Smith Island to a portion of the Hero Fracture Zone.[2] The basin can be subdivided into three basins: Western, Central, and Eastern.[3] The Western basin is 130 kilometers long by 70 kilometers wide with a depth of 1.3 kilometers, the Central basin is 230 kilometers long by 60 kilometers wide with a depth of 1.9 kilometers, and the Eastern basin is 150 kilometers long by 40 kilometers wide with a depth of over 2.7 kilometers.[3]
