Question: Besides the body of water by the city where Erwin Speckler died, and the Irish Channel, what else was lowered in the last cold phase?

Knowledge 1: Rhine
The last glacial ran from ~74,000 (BP = Before Present), until the end of the Pleistocene (~11,600 BP). In northwest Europe, it saw two very cold phases, peaking around 70,000 BP and around 29,000–24,000 BP. The last phase slightly predates the global last ice age maximum (Last Glacial Maximum). During this time, the lower Rhine flowed roughly west through the Netherlands and extended to the southwest, through the English Channel and finally, to the Atlantic Ocean. The English Channel, the Irish Channel and most of the North Sea were dry land, mainly because sea level was approximately 120 m (390 ft) lower than today. [SEP] Knowledge 2: Hamburg
Hamburg is at a sheltered natural harbour on the southern fanning-out of the Jutland Peninsula, between Continental Europe to the south and Scandinavia to the north, with the North Sea to the west and the Baltic Sea to the northeast. It is on the River Elbe at its confluence with the Alster and Bille. The city centre is around the Binnenalster ("Inner Alster") and Außenalster ("Outer Alster"), both formed by damming the River Alster to create lakes. The islands of Neuwerk, Scharhörn, and Nigehörn, away in the Hamburg Wadden Sea National Park, are also part of the city of Hamburg. [SEP] Knowledge 3: Erwin Speckter
Erwin Speckter (18 July 1806, Hamburg - 23 November 1835, Hamburg) was a German painter, often associated with the Nazarene movement.

The English Channel (French: la Manche, ``The Sleeve ''; German: Ärmelkanal,`` Sleeve Channel''; Breton: Mor Breizh, ``Sea of Brittany ''; Cornish: Mor Bretannek,`` Sea of Brittany''), also called simply the Channel, is the body of water that separates southern England from northern France, and links the southern part of the North Sea to the Atlantic Ocean. It is the busiest shipping area in the world.

Answer: English Channel
