The '''Lindsey Islands''' (73°37′S 103°18′W) are a group of islands lying just off the northwest tip of the [[Canisteo Peninsula]] in the [[Amundsen Sea]].

The Lindsey Islands are situated west of the northern extremity of [[Canisteo Peninsula]], which projects into the eastern Amundsen Sea between [[Ferrero Bay|Ferrero]] and [[Cranton Bay]]s on the [[Walgreen Coast]]. The island group consists of one large island that is several kilometers wide, and a smaller island to its west with several nearby outliers further west. The total land area of the collective islands is approximately 2,100 acres.

The total land area of the collective islands is approximately 2,100 acres.  


Some descriptions (e.g. Lindsey 1995) include the island group 5 kilometers to the southwest as within the Lindsey group. However, these were later named the [[Schaefer Islands]] by U.S. place naming authorities. Available mapping incorrectly shows many of the individual islands within the group as merged together.

The island group is the emergent part of a shelf that is less than 200 meters deep, and is formed of granitic rocks. The islands are relatively flat, the highest point being about 40 meters on the largest island. The islands are mostly ice free in summer, and two small freshwater ponds are present on the largest island.

===Animal life===
Approximately 52 breeding pairs of [[Adélie penguin]]s were present on the Lindsey Islands as estimated from March 2011 satellite imagery. The colony occupies the eastern and southeastern coasts of the eastern island, and most of three main outliers and the northern half of the largest of the western group of islands. [[South polar skua]]s are also reported to breed on the islands, although numbers are not known.


Approximately 52 670 breeding pairs of Adélie Penguin were present on Lindsey Islands as estimated from March 2011 satellite imagery (unpublished data, H. Lynch & M. LaRue pers. comm. 2014). The colony occupies the eastern and southeastern coasts of the eastern island, and most of three main outliers and the northern half of the largest of the western group of islands. South Polar Skuas (Catharacta maccormicki) are reported to breed on the islands, although numbers are not known (Lindsey 1995). No other birds are known to breed in the area.
[[Southern elephant seal]]s and [[Leopard seal]]s have been reported in the area.


Non-bird biodiversity: Southern Elephant Seals (Mirounga leonina) and Leopard Seals (Hydrurga leptonyx) have been reported in the area (Lindsey 1995).
===Vegetation===
[[File:Lindsey Island Algae.png|350px|thumb|''Prasiola crispa'' algae in bloom on Lindsey Island. ]]
Due to the extensive ice-free areas on the islands as well as the Adélie Penguin colonies, the algae ''[[Prasiola crispa]]'' has successfully established a foothold. From November - March, the blooming algae blankets portions of the islands in a spectacular green carpet in stark contrast to the otherwise bleak surroundings.


The IBA qualifies on the basis of the Adélie Penguin (Pygoscelis adeliae) colony present, and comprises all of the (more narrowly defined) Lindsey Islands group and the intervening marine area.
When not in bloom, the algae has a reddish-brown color.

==Baron of Lindsey==
==Baron of Lindsey==
On 18 May 2016, Mr. Massimo Zanne, a long-time supporter of [[Westarctica]] from Italy, was granted the [[Hereditary Nobility of Westarctica|hereditary title]] Baron of Lindsey. His title was so-named for the Lindsey Islands.
==Weather and climate==
In February 2008, a team from the South Korean Polar Data Center installed an [[automatic weather station]] (AWS) on the largest and most easterly island of the Lindsey Islands. Averaged data collected at one and two hours is stored in a data logger, and then an Argos Satellite transmitter is used to transmit the two-hourly averaged data. The instruments installed on the AWS include:
* Temperature and Relative humidity probe(Vaisal HUMICAP® Humidity and Temperature Probe)
* Digital barometer(Vaisala BAROCAP® sensor)
* Wind sensor(OEM air flow sensor)
