As climate change continues to reshape our oceans, science communication remains vital to the research and development of mitigation strategies. For scientists and engineers working on climate solutions, much of the conversation happens through technical papers, conference presentations, and policy memos. But invested communities outside these circles may have little access and limited time to con ...[Read More]

Where Freshwater Meets the Fjord: Researching Carbon in a Changing Arctic

Maurie Keppens September 9, 2025

We sat down with Henry Henson, a PhD student at Aarhus University, whose path led from an early love of nature to studying the frontlines of climate change in the Arctic. Henry works with both Aarhus University’s Arctic Research Centre and the Greenland Climate Research Centre in Nuuk, exploring how Greenland’s coastal oceans absorb CO2 and how a warming, freshening Arctic is transforming these fr ...[Read More]

The Untapped Potential of Citizen Science Onboard Expedition Cruise Vessels

Holly Stainton July 11, 2025

Guests participating in the FjordPhyto citizen science project. Antarctic Peninsula, January 2025.

Scientific work can be done not only by professional scientists but also by the general public, often in collaboration with scientific institutions. At HX Expeditions, citizens have the opportunity to contribute to scientific projects on expedition cruises. Join us as we hear from Holly Stainton, the Science & Education Coordinator at MS Roald Amundsen and HX Expeditions, about her experiences ...[Read More]

Phytoplankton are tiny, single-celled organisms mainly found in the ocean’s sunlit surface, where they grow through photosynthesis, forming the marine food web’s base and regulating Earth’s climate by absorbing carbon dioxide. Their seasonal growth cycles—known as “blooms”—drive marine productivity and influence everything from carbon uptake to food security. But how can we track ...[Read More]
