The vessel projections shown for the high scenario in
2025 for monthly ship
cargo ship traffic.
We developed a simulation model to better show how various projections associated with increased marine traffic in the Bering Sea might look in the coming decades. These simulations are able to help communities and managers better understand future patterns of traffic in the Bering Sea region as a whole, and look more specifically at possible changes in key areas of concern like the Bering Strait.
Following vessel activity analysis and considering vessel type, transit
routes, route timing, routing speed, and ports of call, we developed a novel
agent-based, spatially-explicit, baseline model of current marine vessel traffic patterns. We then applied projections about changes in traffic volume from a report by the US Committee on the Marine Transportation System detailing the 10-year projections of traffic through the Bering Strait to develop a possible future scenario of vessel activity.

Marine Invasive Species
of marine invasive species to the Bering Sea have historically been relatively
low, most likely due to geographic isolation and limited human activity;
however, with changing global shipping patterns and warming ocean temperatures,
introductions are likely to increase. More than 70 marine invasive species have
been identified as either occurring, or having the potential to occur in Alaska
waters based on proximity of species in neighboring regions, presence of
suitable habitat in Alaska, and active vectors that could lead to unintentional
introductions (Alaska Invasive Species Working Group 2010). Our goal is to
perform a marine invasive species risk assessment that will provide the most
up-to-date information for the Bering Sea and investigate risk factors
associated with commercial shipping and fishing traffic.
