Happy (belated) Halloween!

After fighting some rough winds through the Bering Strait, the Sikuliaq has arrived in the operations area as planned! And the rumors are true: the arctic is very cold. The ocean is green and black and so cold that every wave hurls sleet up onto the deck. We all stay inside as much as possible, except for a few nights ago when everyone gathered on the bridge deck to view the northern lights.

This second week has been all about getting into a steady routine. The science team is busy monitoring the multibeam seafloor map and sub-bottom profiler in between casting CTDs, collecting samples, and servicing meteorological buoys. Up on the bridge, the mates and the captain have been fighting the wind and waves (up to 40 knots and 10 feet tall, respectively!) to keep us stable and on the correct heading. And the engineering crew runs the tightest ship I’ve ever seen- a ship like the Sikuliaq requires a labyrinth of machinery to operate in extreme climates like the arctic, and they keep it spotless and running smoothly every single day.

As a marine tech, my job is to collaborate with all of these groups and to help with operations in any capacity I can. I especially enjoyed helping the engineers service the A-frame hydraulics; machinery of that scale is fascinating to me, and I appreciated the chance to get some grease on my brand new work gloves! Another highlight was joining the crew in one of the small boats to recover a meteorological buoy. It’s hard to really appreciate the sheer size and power of the Sikuliaq until you’re sitting in a three-person raft and watching it bear down on you.

I’m excited to see what this coming week holds!

My first week aboard the R/V Sikuliaq has flown by! After arriving in Seward, Alaska, I leapt at the opportunity to do a bit exploring. Seward is a beautiful town with a lot of history, but it’s quiet this time of year as the tourist season winds to a close.

The weather cleared up as the Sikuliaq got underway! The extended maintenance period at the dock in Seward turned out to be a blessing in disguise: the delay prevented us from sailing through an intense storm cell in the Bering Sea. So, we began our transit that would take us through Unimak Pass, along the western coast of Alaska, and eventually through the Bering Strait and across the Arctic Circle.

Today is day 8 of our transit. Winds around 30 knots have been whipping up the waves and slowing our progress towards the Bering Strait– and the turbulence was enough to knock my sea legs right out from under me! I have noticed that the color of the sea has changed the further north we have gone; I have some theories but if anyone happens to know why this is, I would love to learn!

During the transit, I have been getting acquainted with the ship, the crew, and my duties and responsibilities as a Marine Technician. Some projects I’ve tackled so far are installing and calibrating sensors on the CTD array, replacing batteries in universal power system banks, and learning the daily maintenance of tools like the uncontaminated seawater system that allow for the continuous collection of valuable environmental data. In the next week or so, I expect that we will have crossed the Arctic Circle and reached the operations area; I hope to see some ice fields and maybe a polar bear (from a distance.)

The SECURE-IT cyber training cruise aboard the R/V Sikuliaq has come to an end, and I’m writing this final post while taking in the cold Alaskan air after days of navigating the Pacific. It’s hard to put into words how transformative this experience has been, both technically and personally.

Each day onboard was a full-immersion dive into maritime cybersecurity and cyberinfrastructure. We configured segmented networks using Fortinet firewalls, utilized Proxmox virtual environments, and worked with legacy systems still commonly found in real-world maritime operations. We tackled bandwidth limitations, satellite communications, and network segmentation in a way that mirrored actual at-sea constraints—and that’s not something you can fully simulate in a classroom.

One of the most impactful parts of this experience was the people. Having such a diverse crew—ranging from seasoned technologists and marine technicians to undergraduate students from across the country—created an environment rich in what’s known as tacit knowledge. These are the kinds of insights that aren’t always written down—techniques, workarounds, and instincts that come from time spent in the field. Watching the experienced professionals troubleshoot or explain their setups gave me a much deeper appreciation for the human element in technical problem-solving.

Another standout for me was having Tyler Peterson, a former MATE intern, onboard. His background as a marine technician and his experience with more traditional MATE internships helped bridge the gap between the classic marine tech path and this first-of-its-kind cruise focused on Information Technology, cybersecurity, and cyberinfrastructure. While we weren’t supporting an active science mission during this cruise, Tyler helped connect the dots between shipboard IT systems and how they ultimately enable and support scientific research. That context was incredibly valuable—it made the purpose behind the tech we were building feel real and relevant.

Something else that really stuck with me: it takes a variety of disciplines to make scientific research at sea possible. From satellite communications and data acquisition systems to physical deployments like the ARGO floats, the cruise was a reminder that meaningful science only happens when engineers, IT professionals, technicians, and scientists work in harmony. This cruise wasn’t just a training exercise—it was a snapshot of what that collaboration can look like in action.

One of the personal highlights: I earned three cybersecurity certifications during this cruise—two from Fortinet and one awarded by the R/V Sikuliaq team. These credentials not only boosted my technical skill set, but also marked a real milestone in my journey toward becoming a cybersecurity professional in the maritime world.

Massive thanks to the University of Alaska Fairbanks (UAF) for hosting, Fortinet for the technical resources, the MATE program for making this internship possible, the crew of the R/V Sikuliaq, and everyone who made this adventure happen. Special shoutout to Julian Race for leading the charge and creating space for real hands-on learning. I’m leaving this cruise sharper, more inspired, and more confident in my future as a cybersecurity professional in the maritime space.

Until next time—signing off from the Gulf of Alaska.

Hello! I’m currently writing from my newly designated workstation aboard the R/V Sikuliaq, docked at the University of Hawaiʻi Marine Center in Honolulu, Hawaiʻi. We are scheduled to get underway later this evening. The Sikuliaq, operated by the University of Alaska Fairbanks, is a 261-foot ice-capable research vessel, and our current expedition—SEACURE-IT—is focused on advancing cybersecurity practices in maritime environments.

Our mission centers on understanding and strengthening shipboard cybersecurity infrastructure. Today’s focus was building a simulated research vessel network using Fortinet hardware, including a FortiGate next-generation firewall and a FortiSwitch managed switch. Each virtual vessel was named after a Star Trek captain, and I’m pleased to report that the R/V Christopher Pike is now fully operational.

To bring the system online, we began by installing the firewall and switch hardware, gaining access through the serial console port. From there, we configured a VLAN (Virtual Local Area Network) and assigned appropriate switch ports. After establishing basic connectivity, we implemented firewall rules to enable WAN access for the VLAN while maintaining strict segmentation between networks.

One of the critical lessons in maritime cybersecurity is the need to separate Information Technology (IT) systems from Operational Technology (OT). Onboard vessels, OT systems (such as industrial controllers managing propulsion, navigation, and critical mechanical systems) are sometimes based on legacy architectures and lack modern security hardening. Allowing these to share a network with IT systems—or worse, exposing them to the internet—creates serious vulnerabilities. Our firewall policy design reflects this reality, ensuring the IT and OT VLANs remain isolated. It is also best practice to separate these networks so that everyday users do not accidentally interfere with critical operations.

After confirming secure internet access on the IT VLAN, we deployed a lightweight Ubuntu virtual machine using the Proxmox hypervisor. While running on limited hardware, the system performs well thanks to the efficiency of Ubuntu, enabling us to simulate key cybersecurity operations within our constrained environment.

To put our network control to the test, I implemented a multi-layered blocking policy targeting a known security concern: TikTok. Using FortiGate’s Application Control, DNS Filtering, and Web Filtering capabilities, I successfully restricted access to TikTok domains and traffic patterns. As a result, no devices on our network can currently access the platform—a practical example of layered defense and policy enforcement in a live environment.

This experience has already been invaluable. I’m gaining exposure not only to enterprise-grade network security tools, but also to the nuances of securing mission-critical systems aboard research vessels.

Hello, I’m RaymondJames Gallant, a cybersecurity student at Eastern New Mexico University and a 2025 MATE intern. I’ll soon be embarking on a cyber internship aboard the RV Sikuliaq, where I’ll be learning firsthand how cybersecurity supports maritime research and operations. I’m passionate about protecting critical infrastructure and excited to explore the intersection of technology and ocean science. I’ll be using this blog to document my experiences, growth, and reflections throughout the journey—thanks for following along!
