Jærens rev

Jærens rev (Jæren's reef) is the westernmost sandbank on the coast of Jæren, located approximately 3 miles off Reve in Klepp municipality, between Orrestranda and Borestranda. Its location has been used to define the limits of the Norwegian fishery zone.

The shoal
The shoal is a partly stony sandbar and extends almost 2 nmi to the west in front of the Revtangen headland, the westernmost point of Jæren. It is very shallow: at Klausgrunnen, about 1.5 nmi off the coast, the water depth is still only 3.5 m. A light buoy is located about 1.8 nmi off the coast at the western end of the shoal, approximately at position 58 ° 45 'N, 5 ° 26' E, for safe passage making. A 16.5 m high steel mark on Revtangen built in 2004 also serves as a navigational beacon; its top mark has a side length of 4 m. A first wooden navigation mark was set up here as early as 1854; it was replaced by a steel construction in 1911, which was dismantled in 1994 and only replaced by the current beacon ten years later.

About 6 nmi further north-northeast is the Feistein Lighthouse on the small Feistein archipelago, at 58°49′35″N 05°30′19″E.

Wildfowl
Jæren's rev is a very well known locality for waders, and since 1937 Stavanger Museum has had an ornithological station (Revtangen Ornithological Station) on the mainland nearby. The Norwegian Air Force took possession of parts of the site in the 1950s as a target area for bombs and gunfire, and the ornithological station was therefore relocated in the autumn of 1954 about 1.5 km further northeast, to a point near the Reve farms, where it is still located today. Every year between 6,000 and 12,000 waders and passerines are caught there, ringed and then released again. Almost 300 different bird species have been observed there since its opening.

Wrecks
The reef has been the scene of many shipwrecks along the harsh Jær coast. In his book «Skipsforlis rundt Jæren» (tr. "Shipwreck around Jæren"), Erik Bakkevig writes of 394 shipwrecks along the Jæren coast over the years.

The Norwegian cargo ship MS Knute Nelson sank at Jærens rev on 27 September 1944, together with two other ships in the same Axis forces convoy, which encountered a French-laid minefield.

Rescue station
A rescue station was established here in 1852, and remained in operation until 1993.
