In addition, the IWC undertakes co-ordinates and funds conservation work on many species of cetacean. Through its Scientific Committee it undertakes extensive study and research on cetacean populations, develops and maintains scientific databases, and publishes its own peer-reviewed scientific journal, the Journal of Cetacean Research and Management. Subsequent work has shown that marine debris, such as ALDFG and plastics, including microplastics, can be a conservation and welfare concern for cetaceans throughout the oceans.
