7 November 2014: SatMex8 beam 2 service in the Gulf doubles

The HiSeasNet service for the Ku-band ships in the Gulf of Mexico and southern US coastal areas doubled. The ships are now sharing a 512 Kbps link from shore to ship while each ship has a 128 Kbps link from ship-to-shore.

31 October 2014: Earth Station modems and amplifiers upgraded

The San Diego earth station has new amplifiers for all antennas. The Ku-band system now sports a 150W amplifier, while the C-band systems are running 250W amplifiers. The old Comtech CDM-550 modems were replaced with Teledyne Q-Flex modems. As matching modems are installed on the vessels over the coming months, more efficient services will be enabled.

20 September 2014: Atlantic Explorer link speed doubles

R/V Atlantic Explorer is now operating on a 256 Kbps bidirectional link. This is a doubling of their previous 128/128 Kbps link.

10 April 2014: R/V Thompson expands bandwidth to stream video from Nereus ROV

University of Washington's R/V Thomas G. Thompson has expanded its HiSeasNet bandwidth to enable a real-time video stream from the WHOI's Nereus ROV. The 1.2 Mbit ship-to-shore bandwidth will, for the next few weeks, support real-time video from the seafloor as the ship works in the western Pacific Ocean.

12 Dec 2013: AGU Poster

HiSeasNet engineer, Steve Foley, will present a poster at the American Geophysical Union Fall Meeting on December 12th, 2013. The poster is titled "The next generation of ship-to-shore networking from research vessels". The poster can be found on the HiSeasNet wiki.

7 Dec 2012: AGU Poster

HiSeasNet engineer, Steve Foley, presented a poster at the American Geophysical Union Fall Meeting on December 7th, 2012. The poster is titled "Efficient use of satellite bandwidth for shipboard science platforms."

7 November 2012: Transition to IS-23

HiSeasNet's Atlantic Ocean Region service is now being provided by the IS-23 satellite operated by Intelsat. IS-23 replaces IS-707 in Intelsat's satellite fleet, and is currently providing cleaner, stronger signals for the AOR ships and British Antarctic Survey station on South Georgia Island. The transition went smoothly with only about 1 minute of outage, and all stations appear to be operating normally again.

10 September 2012: Streaming seafloor video from R/V Revelle via a HiSeasNet bandwidth expansion

For the NOAA/NSF sponsored Submarine Ring of Fire 2012 cruise (Sep 9-26, 2012), R/V Revelle is hosting an ROV exploring underwater thermal vents in the Lau Basin. In order to support real-time streaming video from the seafloor, HiSeasNet temporarily expanded the ship-to-shore bandwidth from the normal 96kbps to 1.6Mbit. The video from this link is being streamed at http://oceanexplorer.noaa.gov/explorations/12fire/media/12firestream_pla... for all to view during the ROV dives. Follow along with the cruise via its website at http://oceanexplorer.noaa.gov/explorations/12fire/welcome.html.

29 November 2011: AGU poster

HiSeasNet engineer, Steve Foley, will present a poster at the American Geophysical Union Fall Meeting on December 7th, 2011. The poster is titled "Data stream mobility across shipboard satellite networks."

18 Aug 2010: Wecoma moves to Galaxy-18

As the R/V Point Sur (MLML) returned from operations in the Gulf of Alaska today, the R/V Wecoma (OSU) has taken up its satellite connection through the Galaxy-18 satellite operated and downlinked by Intelsat. They are operating with a 64kbps link that is ultimately routed through the HiSeasNet earth station facility.
