AB: HiSeasNet is a satellite communications network providing continuous Internet connectivity for oceanographic research ships and platforms throughout the Pacific, Atlantic, and Indian oceans. With the addition of new vessels and satellites in the network, HiSeasNet now uses five satellite beams to extend campus networks out to 13 ships at sea as well as a seismic observatory on South Georgia Island in the Southern Ocean. This year (2007) HiSeasNet has also supported ship operations in the Indian Ocean using a ground station in Germany. Employing a variety of networking technologies, HiSeasNet has allowed scientists to conduct videoconference outreach programs, maintain limited long-term real-time data collection, connect campus phones to shipboard phones through the ship's PBX using Voice over IP (VoIP) protocols, and direct multi-ship research from shore and other ships. Standard Internet protocols available include FTP, https, and ssh. With still more bandwidth available for data, this system can provide new opportunities for enhancing ship-based ocean exploration as well as supporting the long-term data collection projects such as those proposed in the NSF's Ocean Observatories Initiative program. The highest data rate achieved to date was 19 Mbps from the R/V Thomas Thompson off Vancouver. This involved a temporary conversion of the 2.4m shipboard antenna to Ku-Band for relaying HD video from the seafloor to the Internet ashore for real-time imagery of vent activity on the seafloor. The R/V Roger Revelle and R/V Melville include NSF Real-time Observatory and Data management Network (ROADNet) Points- of-Presence aboard ship for buffering and delivering shipboard data to shore continuously and in near-real-time. ROADNet is providing the baseline technology for the OOI Cyberinfrastructure Implementing Organization – the extension of this capability to more of the UNOLS fleet can provide near-real-time data for the OOI for non- proprietary data (e.g. meteorology and acoustic Doppler current profiler) to shore for general access and use.
