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 up to 96/160 kbps, fast enough for a live webcam session. Here, the ship's in port in Dunedin, New Zealand.
