A few points related to the Fleet Broadband communication system

  • The ship “monitors” the voice channel continuously. Persons ashore dial the ship as an international telephone call.

  • All outgoing traffic is logged for record and billing purposes. All research-related traffic will be charged to the scientist’s project. All personal traffic must be charged on a credit card or be made collect. Incoming traffic is paid by the originator. The ship’s station will not accept collect or reverse charge calls.

  • Caution: communication via satellite can be expensive involving satellite use as well as land line charges. Telephone and fax rates can exceed tens of dollars per minute. These rates apply to messages originating ashore as well as aboard ship.

HiSeasNet

An Internet access tool called HiSeasNet is now available on Knorr. This system increases the ship's capability to send and receive data and adds a Voice-Over-IP (Internet Protocol) feature, making ship to shore calls possible. This is all done at minimal cost. The following are some of the system's features and associated implications:

  • Email is transferred every 10 minutes
  • Web browsing is permitted from the science network
  • Email filters for incoming email messages will be set to the default size of 10K for all users. The filter size can be increased if needed.
  • No incoming connections to the ship are allowed except for ssh connections necessary for maintainance activities
  • There are 2 VOIP phones available for general use on the ship. The quality is highly variable depending on the amount of traffic on the HiSeasNet link at the time of the call. No incoming calls to the ship are permitted.

General Communication Information

  • The vessel can transmit on any Marine Band SSB frequency. At sea the vessel continuously monitors 2182 kHz SSB, Channels 13 and 16 VHF and INMARSAT.
  • E-mail -- see the shipboard computing section for information on electronic mail. The ship’s Internet addresses are of the form username@knorr.whoi.edu.
  • The Master is legally responsible for all communications emanating from the vessel. The Chief Scientist should discuss unique or extensive communication needs with the Master.
  • The placing of amateur radio equipment on board the vessel is permitted but must be done with the approval of the Master and the Marine Electronic Supervisor Mike Gagne (mgagne@whoi.edu). Amateur operators and their equipment must be duly licensed and operated in compliance with FCC regulations.
  • All antenna systems, either personal or scientific project related, must be placed in such a manner so as not to interfere with other equipment. Installation of antennas must be done with the approval of the Marine Electronics Supervisor Mike Gagne (mgagne@whoi.edu) and/or the Master.
