Researchers to probe undersea ‘blue hole’ off Florida: report

The video explores the Green Banana, a massive undersea cavern off Florida's coast. Managed by NOAA, this year-long expedition investigates the blue hole, an oceanic sinkhole equivalent, estimated to be 425 feet deep. Due to its narrowness, divers, not drones, will explore it. Blue holes may host diverse marine life, including sea turtles, corals, sponges, and sharks, in otherwise barren ocean regions.

What is the Green Banana, and where is it located?

• A type of fruit found in Florida

• A famous beach in Florida

• A new species of marine life

• The United States Navy

• The National Oceanic and Atmospheric Administration

• The Florida State University

• The Charlotte Observer

What is a blue hole, and how deep is the Green Banana estimated to be?

• A type of coral reef, 100 feet deep

• An oceanic sinkhole, 425 feet deep

• A deep-sea trench, 1000 feet deep

• A shallow lagoon, 50 feet deep

Why might drone submarines face challenges in exploring the Green Banana?

• The cavern is too shallow

• The water is too cold for drones

• The cavern is too narrow in many places

• The drones are not waterproof
