Buchanan Point at the north-eastern end of the island, with Cape Whitson on its south coast, are Important Bird Areas.

[4] William S. Bruce conducted the first comprehensive scientific study of Laurie Island during the Scottish National Antarctic Expedition.

The British Government had previously refused to carry on the Scottish National Antarctic Expedition's scientific studies, as they considered Laurie Island itself worthless.

[6] Nevertheless, Bruce's offer was accepted, and the Argentines would continue operating the meteorological station at Omond House, sending a ship each year to replenish supplies.

The Argentine occupation of Laurie Island posed a problem for this strategy, as it weakened Britain's claim to the South Orkneys.

The post office went inactive shortly after, until 1942, when Argentina restarted postal services, in part to assert its claim to the South Orkney Islands.

The greywacke contained grains of many different minerals, quartz being the most numerous, along with plagioclase feldspar, titanite, zircon, biotite, chlorite, and veins of calcite.

Based on Pirie's incorrect analysis of the "graptolites", geologist I. Rafael Cordini dated the rock's genesis to the Ordovician Period.

The reassessment of Pirie's fossils as plant remains dates the formation of the Greywacke to the Carboniferous Period, many millions of years later than originally thought.
