"A complete understanding of the extent and chronology of Quaternary glaciation requires evidence from both terrestrial and marine evidence - discuss."

"Just as you cannot see your own footprint in the sand while your foot is covering it, you cannot see the effects of an active glacier at its base or sides. Only when the ice melts is its geological work of erosion and sedimentation revealed."

-Press and Siever 2000-

Introduction

The effects of glaciations in the last quaternary were global, thus information about them is hidden both terrestrially and in marine sediments. They type of information revealed in each of these areas varies both in detail and in what information they actually give. Depending on what information you require, it may be worth focusing on one particular information source. However, it may not be regarded as wise to do this, as you may inhibit your ability to obtain a complete understanding.

It is marine sediment analysis that was first used to study Quaternary environments, with the first piston corers being developed in the USA in 1945 (kingdom drilling 2004). With the aid of improved technologies for coring materials and data analysis, it could be
