1 April 2015: Pacific Ocean Satellite change and bandwidth increase

As of this afternoon, the Pacific Ocean Region (POR) service to the large C-band ships is 2 Mbit from shore-to-ship and 256kbps from ship-to-shore for each vessel at sea. This represents a great increase in the bandwidth available to and from those research vessels. Service is now being provided by Intelsat's IS-18 satellite.

13 March 2015: Gulf Ku-band service (SatMex8 beam 2) expanded

The satellite-based internet service offered to the ships operating in the Gulf of Mexico and South America footprint of SatMex8 was upgraded. The ships how have a shore-to-ship bandwidth of 1 Mbps and return ship-to-shore carriers of 256kbps per slot. This represents a doubling of the bandwidth available to and from those research vessels over their expansion in November 2014.

11 March 2015: North America Ku band service (SatMex8 beam 1) expanded

The satellite-based internet service offered to the ships operating in the North America footprint of SatMex8 was upgraded. The ships how have a shore-to-ship bandwidth of 768kbps and return ship-to-shore carriers of 256kbps per slot. This represents a great increase in the bandwidth available to and from those research vessels.

6 March 2015: AOR bandwidth increased 4-fold

As of this afternoon, the AOR service to the large C-band ships is 2 Mbit from shore-to-ship and 256kbps from ship-to-shore for each vessel at sea. This represents a great increase in the bandwidth available to and from those research vessels. More expansions will be coming later this month for the other satellite beams.

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."
