It was not until the winter of 1902/1903 that the expedition led by Otto Nordenskjöld found out that Haddington Land is actually an island and called it James Ross Island in honour of its discoverer.
Až v zimě 1902/1903 však výprava Otto Nordenskjölda zjistila, že Haddingtonova země je ve skutečnosti ostrovem, a pojmenovala jej na počest svého objevitele ostrovem Jamese Rosse.
