Well, all us farm boys know...
Interesting problem. It seems if you use different hectare/acre/sq. mile online calculators, you get different results. I won't use them again!
In my books, I used the Mexican federal government documents that described the legal measurement of the island when the federal government determined how many hectares the island comprised in order to determine the amount of land to distribute to the city, the state, and to the ejidos. I made the mistake of trying to translate those measurements into the terms Norteamericanos use. Looks like land got "lost in translation".
It seems I am not the only one to miscalculate. As I mention in my book, the original land survey measured 39,415.21 hectares. In 1944, they realized that survey was short by 4,481 hectares, so they corrected it to 43,896.21 hectares. I will let Dandy Don translate that into a measurement of land you are familiar with.
Isla Tiburon has 130 km of roads, two airstrips, a wildlife research station, a few buildings to house visitors, and two permanent military bases with military personnel living and working there year-round. It is not a “deserted island”, but is often described as “uninhabited” online. The island is only 3 kilometers from the mainland.
In 1946, Mexico’s
Secretaria de Educacion Publica (SEP) issued a book by Manuel Muñoz Lumbier entitled
Islas Mexicanas, which showed Isla Bermeja in the same approximate location as it had always been shown since 1535. The book localized Bermeja precisely at 22 degrees, 33 minutes North Latitude, 91 degrees 22 minutes West Longitude and
stated that its surface area encompassed 80 square kilometers!
I wrote about Bermeja Island on my website, EverythingCozumel.com
