The HiSeasNet team of Walsh, Kevin P., Pumphrey, Mark and Kapusta, Karl are on site in Honolulu, HI to help the R/V Marcus G. Langseth get a new pedestal before she sails to parts west.  The previous one had lived past is usable life and it is time for service.

Welcome Mark Pumphrey

The HiSeasNet team would like to welcome our newest member to the HiSeasNet team: Pumphrey, Mark.

While Mark has many skills and achievements that could be listed, we'll briefly mention that he has 8 years of experience in the US Navy, and comes to us most recently from UC San Diego's San Diego Supercomputer Center. Mark has a depth of experience in running multiple projects at once in support of High Performance Computing (HPC) research efforts, designing, documenting and maintaining many advanced computing systems with automated techniques. We are excited to welcome someone with his skills and enthusiasm for well-engineered technical solutions to the team.

Mark will attend RVTEC 2017 where we are excited to introduce him to the the seagoing community.

Welcome Kevin Walsh

HiSeasNet welcomes a new network engineer, Walsh, Kevin P.. Kevin will replace Steve Foley as the primary HiSeasNet technical contact. Over the next while, Kevin will be ramping up on the project, and he looks forward to engaging with techs and scientists soon.

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.

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.

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.

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.

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.

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.

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

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.

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.

Welcome Jon C. Meyer

After years of experience with the wet side of the HiSeasNet links on the SIO vessels, Jon Meyer has just joined the shore side to some extent. While he has plenty of other work to do on some other projects at SIO, you may see him chiming in on some things from time to time or picking up some slack when I am unavailable.
