SMS Markgraf

Markgraf stood in the thick of Jutland in 1916, trading salvos with the British battle line and taking hits that killed members of her crew, then endured the hungry, mutinous final years of the German fleet before sailing into internment at Scapa Flow. On 21 June 1919 she answered von Reuter's scuttling signal, and her sinking carried the day's sharpest tragedy: as British guard boats tried to force crews back aboard, her commanding officer, Walter Schumann, was shot and killed, one of the last men to die in the First World War's naval conflict, months after the armistice. The Markgraf sank into the deepest water of the seven survivors and lies today almost completely upside down in about 45 meters, the most demanding and, many say, the most rewarding of Scapa's battleships. Her hull sides drop like cliff faces, rudders and shafts crown the upturned stern, and along the seabed the casemate guns and armored belt emerge from the gloom. Divers treat her with particular respect, both for her depth and for the men who died with her.

她是如何沉没的: Scuttled with the interned German High Seas Fleet on Admiral von Reuter's order, 21 June 1919.

环境条件: Largely intact inverted hull, the least salvage-damaged of the battleships, with slow internal collapse

穿越式潜水: Limited. Interior access is deep technical territory: dark, silted and structurally suspect; most visiting divers never leave the hull exterior. 进入任何封闭式环境都需要专项培训：至少需要沉船潜水认证，完整穿越则需要技术级沉船培训。

建议持有证书: Deep or technical qualification; the hull top alone suits experienced advanced divers

水流: Mild · 能见度: 4–12 m

海洋生物: Anemone-crusted plating, shoals of saithe and pollack along the hull sides, wolf-eel-like butterfish in crevices, congers and lobsters in the wreckage, brittlestar beds on the floor.

危险因素: Depth beyond recreational limits at the seabed, cold and dark, overhead structure, and old netting
