Heligoland (; German: Helgoland, pronounced [ˈhɛlɡoˌlant] ; Heligolandic Frisian: deät Lun, lit. 'the Land', Mooring Frisian: Hålilönj, Danish: Helgoland) is a small archipelago in the North Sea, administratively part of the German state of Schleswig-Holstein. The islands are located in the Heligoland Bight (part of the German Bight) in the southeastern corner of the North Sea and are the only German islands not in the vicinity of the mainland: they lie approximately 69 kilometres (37+1⁄2 nautical miles) by sea from Cuxhaven at the mouth of the River Elbe. The islands were historically possessions of Denmark, then became possessions of the United Kingdom from 1807 to 1890. Since 1890, they…

Behaviors of Grey Seals (<i>Halichoerus Grypus</i>) Addressed Towards Human Swimmers During Experimental Open Water Encounters Off Heligoland (German Bight, North Sea). Risks arising for humans during swim encounters with seals are poorly understood. This study was initiated to examine behaviors of unhabituated grey seals addressed towards humans during experimental, noncommercial seal-swim activities off Heligoland. In total, 26 in-water encounters were conducted. Behavioral classes and the number of seals simultaneously approaching swimmers were time sampled. A set of risky and nonrisky interactive behaviors was continuously sampled. Seals spent approximately the same amount of time inter…

The Frisian Islands, also known as the Wadden Islands or the Wadden Sea Islands, form an archipelago at the eastern edge of the North Sea in northwestern Europe, stretching from the northwest of the Netherlands through Germany to the west of Denmark. The islands shield the mudflat region of the Wadden Sea (large parts of which fall dry during low tide) from the North Sea. The Frisian Islands, along with the mainland coast in the German Bight, form the region of Frisia (German and Dutch: Friesland), homeland of the Frisian people. Generally, the term Frisian Islands is used for the islands where Frisian is spoken and the population is ethnically Frisian. In contrast, the term "Wadden Islands…

The German Bight (German: Deutsche Bucht [ˈdɔʏtʃə ˈbʊxt]; Danish: tyske bugt; Dutch: Duitse bocht [ˈdœytsə ˈbɔxt]); West Frisian: Dútske bocht; North Frisian: Schiisk Bocht; sometimes also the German Bay) is the southeastern bight of the North Sea bounded by the Netherlands and Germany to the south, and Denmark and Germany to the east (the Jutland peninsula). To the north and west it is limited by the Dogger Bank. The Bight contains the Frisian and Danish Islands. The Wadden Sea is approximately ten to twelve kilometres (6 to 10 miles) wide at the location of the German Bight. The Frisian islands and the nearby coastal areas are collectively known as Frisia. The southern portion of the bigh…

The Heligoland–Zanzibar Treaty (German: Helgoland-Sansibar-Vertrag; also known as the Anglo-German Agreement of 1890) was an agreement signed on 1 July 1890 between Germany and the United Kingdom. The accord gave Germany control of the Caprivi Strip (a ribbon of land that gave German South-West Africa access to the Zambezi River), the strategically located archipelago of Heligoland in the North Sea, and the heartland of German East Africa. In return, Germany recognized British authority in Zanzibar. Heligoland was needed to control the new Kiel Canal and the approaches to Germany's North Sea ports. Britain used Zanzibar as a key link in the British control of East Africa.

The Heligoland Bight, also known as Helgoland Bight, (German: Helgoländer Bucht, pronounced [ˈhɛlɡoˌlɛndɐ ˈbʊxt]) is a bay which forms the southern part of the German Bight, itself a bay of the North Sea, located at the mouth of the Elbe river. The Heligoland Bight extends from the mouth of the Elbe to the islands of Heligoland and lies between the East Frisian island of Wangerooge and the North Frisian peninsula of Eiderstedt. The bight takes its name from the island of Heligoland. It was the location of World War I naval battles in 1914 and 1917. In 1939 it also had a World War II aerial battle named after it. In the Heligoland Basin (Helgoländer Becken), a basin lying directly southwest…

Variations in Movement and Habitat Selection by Eurasian Curlew at Two Important Sites in Europe Throughout Winter.. Shorebirds aim to replenish their body reserves during the wintering season to ensure their subsequent survival and to improve their breeding performance. However, their space use depends on their fluctuating resource availability and energy requirements throughout the winter. Hence, this study aimed to determine if the space and habitats used by Eurasian curlews ( Numenius arquata ) were influenced by their wintering site and stage. Sixty-two curlews were equipped with GPS tags at two major wintering sites in Europe with contrasting waterbird density: the Pertuis Charentais…

The late Holocene demise of a sublittoral oyster bed in the North Sea.. A fossil oyster bed (Ostrea edulis) was recently encountered offshore Helgoland (German Bight). Oysters are important filter feeders in marine environments and their habitat structure supports a large associated biodiversity. The European flat oyster Ostrea edulis has historically occurred in vast populations in the North Sea, but declined massively in the early 20th century. The ecological restoration of Ostrea habitats is a current focal point in the North Sea. To better understand the mechanisms that caused the local collapse of the oyster population, this study investigated the size structure, weight, and age of the…

Occurrence and Temporal Variation of Technology-Critical Elements in North Sea Sediments-A Determination of Preliminary Reference Values.. As interest in the investigation of possible sources and environmental sinks of technology-critical elements (TCEs) continues to grow, the demand for reliable background level information of these elements in environmental matrices increases. In this study, a time series of ten years of sediment samples from two different regions of the German North Sea were analyzed for their mass fractions of Ga, Ge, Nb, In, REEs, and Ta (grain size fraction -1 for In to 114 mg kg -1 for Ce. As none of the threshold values exceed the observed natural variation of TCEs…

Comparative metagenomics indicates metabolic niche differentiation of benthic and planktonic Woeseiaceae.. Background Benthic microbiomes exhibit remarkable temporal stability, contrasting with the dynamic, substrate-driven successions of bacterioplankton. Nonetheless, understanding their role in carbon cycling and interactions between these two microbial communities is limited due to the complexity of benthic microbiomes. Results Here, we used a long-reads (LRs) metagenomic approach to examine benthic microbiomes and compared them to the microbiomes in the overlaying water column and on particles, sampled at the same site and time off the island Heligoland in the North Sea. Although the di…
