Document Summary
Wisconsin glacial episode: was the most recent major advance of the north american ice sheet complex. This advance was synchronous with global glaciation during the last glacial period. The wisconsin glaciation extended from approximately 85,000 to 11,000 years ago. Last glacial maximum (lgm): refers to a period in the earth"s climate history when ice sheets were at their most recent maximum extension, between 26,500 and 19,000 20,000 years ago, marking the peak of the last glacial period. During this time, vast ice sheets covered much of north america, northern europe and asia. Glacial periods: individual pulses of cold climate within a long-term ice age. Interglacial periods: intermittent warm periods within a long-term ice age. Marine isotope stages (mis): are alternating warm and cool periods in the earth"s paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples.
