HSN, Others, Behind the Scenes of El Faro Data Recorder Search

Huge congratulations are due to WHOI, the NTSB and the US Coast Guard for successfully locating the voyage data recorder (VDC) of the sunken cargo ship El Faro. SS El Faro was declared missing October 2, 2015, a day after ship encountered Hurricane Joaquin (cat 3) and communications ceased. Locating the VDC, an object the size of a basketball, three miles underwater and 41 miles from land, is a tremendous feat and will hopefully help researchers learn more about the shipwreck.

15 September 2015: Welcome Kevin Walsh

HiSeasNet welcomes a new network engineer, Kevin Walsh. 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.

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.
