Investigate levels of sunscreen pollution and bioaccumulation in Jellyfish Lake, and coordinate a public awareness campaign to reduce activities that may exacerbate threats from invasive species and to endemic species. The former will elucidate links between tourism use of marine lakes and the environmental health of the marine lake ecosystems. The latter will produce a glossy booklet for public awareness, "Jellyfish Lake (Ongeim'l Tketau)," which will be printed in Japanese to be distributed to Japanese dive shops and tourist centers in Palau.
