OSIL Offers New Low-cost Satellite Modem

Ocean Scientific International Ltd (OSIL) has added a new low-cost, low-power satellite modem to its range of telemetry equipment. The system will publish data, including traditionally high cost/volume currents and waves, from any location globally using the Iridium satellite network.    Monthly line rental costs are minimal, and data costs are kept low (as little as 4p per message) by using SBD messaging with big bundle deals available for multiple or long term deployments. Conventionally current and wave data transmitted via satellite has proved expensive for the end user owing to the

AUVs Under Ice: Past Milestones, Promising Future

The marine environments beneath ice are arguably some of the least accessible on earth. Ice is a formidable physical barrier that can range in thickness from centimeters to hundreds of meters—an impediment that has not diminished our desire to uncover the secrets that lie beneath.    In the heyday of manned submarines, under-ice was seen as an important operating theater, where the ability to listen and monitor one’s foes was crucial. As manned submarines have given way to unmanned vehicles, the duties of under-ice research have widened to include more fundamental motivations

A New Era of Antarctic Exploration: AUVs in Polar Science

20th century were the first to combine exploration and scientific discovery in the Antarctic. While the Scientific Committee on Antarctic Research (SCAR) was set up to co-ordinate international activities back in 1958, only in the last few decades have we realized the importance of the Antarctic for marine ecology, ocean circulation and climate change. Given its remoteness, the Antarctic is more accessible than ever.
