Question: What body of water was dry land during the last ice age, besides the Irish Channel and the sea near the former Atlantic Hotel?

Knowledge 1: Islamic Centre Hamburg
During a meeting at Atlantic Hotel (Hamburg) in 1953, a group of Iranian residents of Germany discussed the need to establish their own religious center. A letter was sent to the late Grand Ayatollah Seyyed Husayn Borujerdi asking him for help; Grand Ayatollah agreed with the plan and donated 100,000 Rials to the center. The construction began in 1960 and by 1965 it was completed. In the same year Ayatollah Mohammad Beheshti was appointed to lead the center. [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: 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.

The English Channel (French: la Manche, ``The Sleeve ''; German: Ärmelkanal,`` Sleeve Channel''; Breton: Mor Breizh, ``Sea of Brittany ''; Cornish: Mor Bretannek,`` British Sea''), 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.
