Crater population and resurfacing of the Martian north polar layered deposits [PDF]

open access: yes, 2010
Present-day accumulation in the north polar layered deposits (NPLD) is thought to occur via deposition on the north polar residual cap. Understanding current mass balance in relation to current climate would provide insight into the climatic record of ...
