Planned Research Vessel Movements: 2023 Research Season

Each spring, summer, and fall, numerous research vessels travel through Alaska and Arctic waters. IARPC, federal agencies, and the Alaska Ocean Observing System (AOOS) compile and communicate planned research expedition dates and routes, research goals, and mooring locations. Our hope is that researchers can use this information to coordinate activities, and that communities can use it to understand what vessels are in their waters and how to contact them if necessary.

On this page you will find a spreadsheet with all planned expeditions, brief descriptions of research activities, and a spreadsheet of mooring locations.

The research vessel spreadsheet and descriptions 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 Sarah Tucker (IARPC) and Katy Smith (NSF) with any questions.

Oceanographic moorings provide fixed location time-series ocean observations through a collection of sensors and data collection equipment tethered to a chain and anchored on the seafloor. By maintaining an up-to-date mooring location spreadsheet, 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. It will also facilitate collaborative science activities.

This valuable resource was developed and maintained by Dr. Robert Pickart. Please reach out to sarah.tucker@noaa.gov with any questions.


Pre-field season meeting

On May 25, IARPC held a pre-field season meeting to share information about upcoming expeditions, improve collaboration among Arctic researchers, and expand communications and coordination with local and Indigenous communities.


2023 expeditions

Expeditions here are organized by location, then launch date. If an expedition will visit more than one location, it will appear under both location headers. To see all expeditions at once, download the spreadsheet above, or view the calendar below.

October 6-17
Departs from: Dutch Harbor
Returns to: Shimizu, Japan

Moorings will be recovered and re-deployed on the pathway of the Pacific-origin water to monitor its transport and impact on marine ecosystem. Some flying drones will be used to measure meteorological parameters and to assess the conditions of sea ice and waves. Various drifting buoys will be launched to measure the ocean waves, currents, and temperature.

Arctic Mobile Observing System

October 10 - November 13
Departs from: Nome
Returns to: Nome
Research location: Central Beaufort Sea
Vessel: Sikuliaq (NSF)
Description: Characterizing Arctic ocean-ice-atmosphere variability and predicting the system’s evolution on synoptic to seasonal timescales requires observations that span a broad range of spatial and temporal scales. Forecast quality depends on observations for initialization, assimilation, and informing how the simulations represent unresolved physics. Data intended for use in nowcast/forecast efforts must be delivered in a timely fashion—a challenging requirement for polar regions where ice blocks access to satellite services. To support Navy missions in the ice-covered Arctic, the Arctic Mobile Observing Innovative Naval Prototype (AMOS INP) is developing a mobile observing capability composed of ice-based Gateway Nodes and an array of complementary autonomous platforms (gliders, floats, AUVs), networked together through acoustic navigation and communication to enable coordinated, cooperative sampling and efficient data relay.
