Arctic regions are experiencing warming air, rising ocean temperatures, and reduced sea ice cover. This increases the occurrence of harmful algal blooms in northern latitudes. These blooms consist of high concentrations of toxic algae in coastal marine waters that poison marine life and pose significant threats to human health. The toxins can cause stomach pain, headache, and rashes as well as more serious problems like liver damage, seizures, cardiac arrhythmias, and death. Knowledge of the impact of harmful algal blooms on Arctic populations and marine ecosystems is limited. Once relatively immune to such blooms, Arctic coastal waters are becoming increasingly susceptible to their presence. This research undertakes exploratory research to investigate impacts of harmful algal blooms on Arctic peoples and marine ecosystems. Western Greenland was chosen for the pilot due to its seasonal sea ice cover and the calving of ice bergs from continental glaciers, both of which can host toxic algae. Here local populations subsist primarily on marine mammals and sea life (i.e., seals, whales, fish, and shellfish), all of which, under the right environmental conditions, can contain algal bloom toxins. The project team is composed of scientists who are experts in Arctic environmental science, social scientists, and medical professionals who are well acquainted with Greenland health issues and the associated data. It also includes significant interaction with the local communities to learn
