Invasive species are spreading into northern latitudes and threatening food and water security. Alaska's aquatic environments support some of the world's most productive wild salmon fisheries. Yet, the influx of invasive species increases the strain on the ecosystems, cultures, and economies that depend on these fisheries. Especially worrisome is the potential transmission of aquatic invasive species (AIS) such as zebra mussels (Dreissena polymorpha), quagga mussels (Dreissena bugensis), or Asian clams (Corbicula fluminea) through the trade and traffic of recreational watercraft from AIS-infested regions. Since neither invasive mussels nor clams have been found in Alaska waters, there is opportunity to prevent introductions of invasive molluscs and avoid catastrophic impacts to some of the world's last intact ecosystems. To date little data are available to guide human response to reducing the risk of transmitting freshwater AIS that affect critical natal habitat for Alaska's salmon fisheries. This study triangulated existing data on watercraft registrations and inspections with key informant interviews to establish a first estimate of introduction rates for watercraft-related AIS. Results show that at least 129 used and motorized watercraft are estimated to enter Alaska annually from dreissenid-infested regions with an estimated 47 reaching Alaska freshwater uninspected. These watercraft are entering Alaska through both land and marine pathways. The study points toward the need for a collaborative response among state, federal, tribal, and local agencies, and watercraft owners to devise effective prevention. Response opportunities include inspections and decontaminations at critical control points, and an increased outreach and education campaign for watercraft users. Policy implications for salmon fisheries are discussed should AIS become established in Alaska. Also, the costs, and the long-term sustainability of a prevention program are discussed.

The University is working with the Port of Dover and the University of Manchester to create a digital twin of Dover harbour.

Antarctica is experiencing rapid and complex change, and it is critical to have a better understanding of these changes for the region's ocean ecosystems. The costs and logistical challenges to operate scientific research vessels prohibits the scaling of crucial science and discovery in the region. Yet, the tourism industry in Antarctica is growing rapidly, and collaboration between tourism companies and researchers provides important access to the region. While researchers gain from free or discounted ship time, it also provides the travel companies with enrichment opportunities for their guests. Scientists have been conducting research aboard platforms of opportunity (POMs) like tourism or cargo ships for decades, studying oceanographic conditions as well as organisms from phytoplankton to marine mammals, with some of the earliest published research using data collected aboard cruise ships headed to Antarctica. As the number of Antarctic tourism vessels has increased to over 70 boats, more research and citizen science projects are successfully expanding to take advantage of these POMs in Antarctica.

- A UK-first collaboration is set to use satellites to monitor coastal changes in a bid to create safer shipping navigation channels. - The project will see Peel Ports, the UK's second largest port operator, partner with the National Oceanography Centre (NOC) and Channel Coastal Observatory (CCO) to employ satellite surveillance and assess where maintenance is needed over a six-month period. - Funded by UK Space Agency Small Business Research (SBRI), we will use our patented coastal mapping technology to support Peel Ports in building targeted dredging operations across the Mersey and Medway estuaries. - Offering greater insight into changes to the marine environments around two of the UK's most important waterways, Peel Ports will use the data to ensure safer access to the Port of Liverpool and Port of Medway for arriving ships.
