Drifter velocity measurements can have a substantial impact on the ECCO large-scale time-mean surface circulation over extensive areas.. . Albedo increases due to more ice coverage to something like about 0.35 which is then equivalent to a 6% change (3 % change in mean geometric distance from the Sun). Qualitative Albedo Feedback loop:.
