The city and harbor of Den Helder in the northern Netherlands has been the home port of the Dutch Royal Navy for over 175 years. Its favorable location provides access to the North Sea, and has made it an important commercial shipping port in addition to its strategic role. Bright red agricultural fields to the south of Den Helder indicate another noteworthy aspect of the region--commercial farming of tulips and hyacinth. This image is an oblique view--the camera is oriented at an angle relative to "straight down"--of the Den Helder region taken from the space station, which was located to the southeast, near Dulmen, Germany (approximately 225 kilometers away in terms of ground distance) when the image was acquired. In addition to the manmade structures of the Den Helder urban area (reddish gray to gray street grids) and dockyards to the east of the city, several striking geomorphic features are visible. The extensive gray mudflats, with their prominent branching pattern (top right), indicate that this image was acquired at low tide, and suggest the general low elevation of the region. Parallel wave patterns along the mudflats and in the Marsdiep strait are formed as water interacts with the sea bottom between Den Helder and Texel Island during tidal flow. Some ship wakes are also visible. According to scientists, the bright white-gray triangular region at the southern tip of Texel Island (bottom center) is a dune field, consisting mainly of eolian (windborne) sands deposited during the last Ice Age. Subsequent sea level rise and shoreline processes have mobilized and re-deposited these sands into their current configuration -- including a new dune field island to the southwest of Texel (bottom center).
Den Helder, Netherlands:
The city and harbor of Den Helder in the northern Netherlands has been the home port of the Dutch Royal Navy for over 175 years. The location provides access to the North Sea, which has made it an important commercial and strategic port. Bright red agricultural fields to the south of Den Helder indicate another noteworthy aspect of the region--commercial farming of tulips and hyacinth. This astronaut photograph is an oblique view (an angled, not a "straight down"view) of the Den Helder region taken from the International Space Station (ISS). The ISS was located to the southeast, near Dulmen, Germany, when the image was acquired, about 225 kilometers (140 miles) away in terms of ground distance.
In addition to the urban structures of the Den Helder area (reddish-gray to gray street grids) and dockyards to the east of the city, several striking natural features are visible. The prominent branching pattern of the extensive gray mudflats (image bottom right) indicate that this image was acquired at low tide, and show the generally low elevation of the region. Parallel wave patterns along the mudflats and in the Marsdiep Strait are formed as water interacts with the sea bottom between Den Helder and Texel Island during tidal flow. (Some ship wakes are also visible.) The bright, white-gray triangular region at the southern tip of Texel Island (image upper left) is a dune field, consisting mainly of eolian (wind-borne) sands deposited during the last ice age. Subsequent sea level rise and shoreline processes have shifted these sands into their current configuration, which includes a new dune field island to the southwest of Texel.
