Nigehörn (German pronunciation: [ˈniːɡəˌhœʁn]) is an uninhabited artificial island in the North Sea belonging to the German city of Hamburg.

The Unterelbe (German pronunciation: [ˈʊntɐˌʔɛlbə] ) or, in English usually the Lower Elbe, refers to the lower reaches of the river Elbe in Germany influenced by the tides.
It starts at kilometre 586, at the sluice of Geesthacht, where the Elbe forms the border between Lower Saxony and Schleswig-Holstein. It continues downstream, then forming the border between Lower Saxony and Hamburg, before fully entering Hamburg territory. In Hamburg the Unterelbe forms two anabranches, Norderelbe and Süderelbe, the latter now partially a cut-off meander. Where Norderelbe and Süderelbe used to reunite, at kilometre 634 there is a bay called the Mühlenberger Loch. This marks the beginning of the section of the Unterelbe which called the Niederelbe. After leaving Hamburg it forms the border between Lower Saxony and Schleswig-Holstein, again. The end it defined by the Kugelbake in Cuxhaven at kilometre 727.73. It continues further into the Wadden Sea as the Außenelbe, where it passes the Hamburg islands Scharhörn and Nigehörn.
A tidal creek or tidal channel is a narrow inlet or estuary that is affected by the ebb and flow of ocean tides. Thus, it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils. Tidal creeks are characterized by slow water velocity, resulting in buildup of fine, organic sediment in wetlands. Creeks may often be a dry to muddy channel with little or no flow at low tide, but with significant depth of water at high tide. Due to the temporal variability of water quality parameters within the tidally influenced zone, there are unique biota associated with tidal creeks which are often specialised to such zones. Nutrients and organic matter are delivered downstream to habitats normally lacking these, while the creeks also provide access to inland habitat for salt-water organisms.
Neuwerk (German pronunciation: [ˌnɔʏˈvɛʁk] ; Low German: Neewark; Archaic English: New Werk or Newark) is a 3 km (1.2 sq mi) tidal island in the Wadden Sea ("Mudflat Sea") a marginal part of North Sea along the German coast. The population in 2023 was 21. Neuwerk is located 13 km (8 mi) northwest of Cuxhaven, between the Weser and Elbe estuaries. The distance to the centre of Hamburg is about 120 km (70 mi).
Administratively, Neuwerk forms a homonymous quarter of the city and state of Hamburg, Germany, and is part of the borough Hamburg-Mitte. This quarter includes the islands of Scharhörn and Nigehörn, which are bird sanctuaries and closed to the public. All three islands and the Wadden Sea around them form the Hamburg Wadden Sea National Park.
