Ísafjarðardjúp (pronounced as /is/) is a large fjord in the Westfjords region of Iceland.[1] Its name translates to Depth of the fjord of sea ice.
Ísafjörður, capital of the Westfjords region, is situated close to the mouth of Ísafjarðardjúp in Skutulsfjörður.[1]
The north-eastern coast is fairly straight with the only inlet being Kaldalón, but the southern side has fjords extending well into the land: Skutulsfjörður, Álftafjörður, Seyðisfjörður, Hestfjörður, Skötufjörður, Mjóifjörður, Reykjafjörður and Ísafjörður.
Three islands lie in Ísafjarðardjúp: Borgarey, Æðey and Vigur. Borgarey is the smallest with no inhabitants and Æðey the largest. On both Æðey and Vigur there is one farmstead.[2]
On the peninsula of Reykjanes, there are hot springs and hydrothermal alteration.[3]
In the bottom of the fjord lies the former trading post Arngerðareyri.[4]
