Langseth’s computer network consists of gigabit networking to all lab spaces, with wireless accessibility throughout the ship. Internet access is on a separate, wired network. Only certain spaces have ports to access the internet. Refer to the Internet Access and Usage policy for details.
Internet access is a limited resource on ships. While HiSeasNet provides a 24-hour connection, bandwidth is less than that of a typical residential DSL service. Please refer to the internet access policy (on the internal Langseth web site) for information detailing how internet access is controlled. Any questions or assistance requirements, please contact the technical staff.
Access to email from home institutions is not blocked, and can be received on the internet-enabled network. Some sites, especially ones that need high-speed internet (YouTube), are blocked.
Large data transfers can be arranged. Transfers can be done at any time during the cruise but require coordination with the technical staff.
Scientists may bring their own computers to the vessel. The techncial staff will provide support in setting up a network connection and access to email, file services, and printing. Windows XP/Vista/7, Mac OS X, and Linux Redhat/Ubuntu/Debian/Fedora are supported.
Scientists may bring workstation computers. Please discuss beforehand with technical staff during planning stages to ensure enough space is available for all equipment. The tech staff will assist users in setting up workstations.
The techncial staff can provide desktop support limited to setting up network access and configuring devices to access network services. Windows XP/Vista/7, Mac OS X, and Linux Redhat/Ubuntu/Debian/Fedora are supported. Limited break/fix support is provided, on a best-effort basis.
Updated anti-virus software is required prior to departure. Failing to update on-coming computers’ anti-virus software puts the entire vessel network in danger.
Langseth provides workstations and software for seismic processing and general-purpose computing. These are located in the Main Lab. For a list of software available on these systems, please refer to the internal Langseth web site. Any questions or assistance requirements, please contact the technical staff.
Internet terminals (at least one) are also provided for crew and science party use. These may be relocated depending on mission requirements. Tech staff will brief the science party on internet terminal access during orientation.
Telephone calls for the PIs can be made from any phone on the vessel. Upon arrival at Langseth, the PI will be issued a code to allow him/her to access an outside line via Fleet Boradband. On weekends, the internet may be secured for up to two hours at a time to allow morale calls for all on board. Morale phone calls are in 15-minute slots.
