Continental Lithosphere: a Broadscale Investigation was a Task Force of the International Lithosphere Program . It was a temporary, international platform for scientific exchange and outreach on the structure, properties and evolution of the continental lithosphere (see proposal description PDF). Beyond many support to projects and early-career scientists, a main output is a series of talks on the lithosphere-asthenosphere boundary available here: https://www.youtube.com/@orog3ny and also embedded below.
