A balloon-like radome atop the R/V Roger Revelle houses an antenna providing Internet access.
The large, balloon-like radome atop the R/V Roger Revelle houses the Seatel antenna, which has brought constant Internet access to the ship since 2002. The antenna sends and receives data at speeds of up to 96/160 kilobits per second (kbps), fast enough for a live webcam session. Here, the ship is in port in Dunedin, New Zealand.
