Caviana (Portuguese: Ilha Caviana, also called Ilha Caviana Meridional or Ilha Caviana de Fora) is a coastal island in the Brazilian state of Pará. The island is part of the municipality of Chaves. The Equator runs through the island, as well as the 50th meridian west.
The island belongs to the Marajó Archipelago, it is located opposite the north coast of Marajó Island in the delta lowlands at the mouth of the Amazon. The island forms part of the low-lying Marajó várzea, the inundated land in and around the mouth of the Amazon River. The island is an excellent place to observe the tidal bore called the pororoca, where the Amazon river waters meet the incoming Atlantic tides and form a standing wave, and is a birdwatchers' haven.
The island is separated from neighbouring island Mexiana by the Canal Perigoso ("Dangerous Channel"). The latter is called such because sandbanks make navigation perilous during low tides.[1]
Caviana is contained in the 59,985 square kilometres (23,160 sq mi) Marajó Archipelago Environmental Protection Area, a sustainable-use conservation unit established in 1989 to protect the environment of the region.[2]
