Planned Research Vessel Movements: 2026 Research Season
Each spring, summer, and fall, numerous research vessels travel through Alaska and Arctic waters. and federal agencies compile planned research expedition dates, planned routes, research goals, and locations of data-collection moorings.
Our hope is that researchers can use the information about research expeditions to coordinate activities, and that communities can use it to understand what vessels are in their waters and how to contact them if necessary. Additionally, with the list of mooring locations we aim to inform the scientific community and vessel operators of the locations of all moorings presently deployed in the Bering, Chukchi, and Beaufort seas. This will reduce the risk of damage to the moorings and facilitate collaborative science activities.
On this page you will find a spreadsheet with all planned expeditions, brief descriptions of expeditions, and a spreadsheet of mooring locations. The spreadsheets will be periodically updated and emailed out to partners. If you would like to receive updates, sign up for the email distribution list.
Please contact field.operations@iarpccollaborations.org with any questions, or to provide additional information about upcoming expeditions.

2026 Pre-field season meeting
On May 14, held a pre-field season meeting. The annual pre-field season meeting is open to federal and non-federal partners, researchers, local and Indigenous community members, and anyone else interested in the 2026 research season. Attendees heard lightning-talk presentations from principal investigators leading research expeditions in Alaska and Arctic waters in 2026, followed by group discussion. The meeting supported the exchange of information about planned expedition objectives and facilitated collaborations that leverage these investments in research about the Arctic marine system. It was hosted by the Field Operations, Sea Ice, and Marine Ecosystems communities of practice.

Departs from: Nome, Alaska
Returns to: Nome, Alaska
Research location: Bering Sea
Vessel: Sikuliaq ()
Description: Oceanographic transects will be conducted in the Chirikov Basin, and to the south and east of St. Lawrence Island (SLI). Transects are designed to capture water-mass boundaries associated with the cold pool and the Yukon River outflow, as well as benthic biomass hot-spots in the 1 and 2 regions. Each of the transect lines includes underway measurements, and towed camera and instrument surveys using the ISIIS-DPI to assess pelagic communities and hydrographic parameters. This Remotely Operated Towed Vehicle (ROTV) can be “flown” in real-time, or automatically execute repeated undulations between programmed depths. Sub-millimeter particle size spectra are measured by a Sequoia Deep-LISST. Larger particles (i.e., zooplankton and micronekton) are surveyed with an onboard SIMRAD EK80 fisheries acoustic package equipped with upward and downward looking 30 and 120-kHz split beam transducers, and supported by the hull-mounted EK80 system.
Along each transect, we will also occupy a series of stations to conduct CTD deployments, phytoplankton and net-collected zooplankton sampling, and sediment sampling using the MC-800 multi-core. Each transect will also include one or more intensive process stations where we will deploy drifting sediment traps, in situ pumps for particle collection, and conduct experimental work. Year-round biophysical and biogeochemical moored instruments would be deployed at three locations, targeting the primary advective pathways on either side of SLI, and multiple water masses and biogeochemical regimes. Moorings would capture time series of water-mass distribution, sediment resuspension events, advection, and the east-west reversing flow south of SLI.
