BAYOU CORNE, La. (AP) — The Public Broadcasting Service television series NOVA is working on a documentary about the sinkhole in northern Assumption Parish.

NOVA producer Larry Klein tells The Advocate a film crew associated with the science program finished up four days of interviews and shooting in Bayou Corne on Friday. Klein says a one-hour program is set to air in the winter of 2015.

The lake-like sinkhole, now covering 32 acres, has drawn worldwide media attention since it appeared in early August 2012, swallowing up a former cypress swamp.

Klein said the program will report on why and where sinkholes occur around the world, and whether their numbers are increasing and whether anything can be done to prevent or lessen them.
