Images of shipwrecks filmed by a Halifax company and 3-D underwater landscapes are part of a new ocean module in the latest version of Google Earth.

The module is included, along with new GPS tracking functions, sequences of satellite images of a single location over time and imagery from the surface of Mars, in version 5.0 of the internet program, which became available for download beginning Monday.

The program bills itself as a virtual globe, including satellite images, maps and search functions.

Halifax-based Eco-Nova Shipwreck Central Inc., which produces documentary films about shipwrecks, provided some of the images in the ocean feature.

John Davis, producer at Eco-Nova, said his company has been shooting footage of shipwrecks for almost 15 years and is delighted the images are available to a wider audience.
