#Chondria tumulosa
New locations of ‘nuisance alga’ found in Papahānaumokuākea Marine National Monument
When National Oceanic and Atmospheric Administration divers first detected the alga in 2016, it grew in lower abundances and was not yet widespread. By August 2019, the algae had grown into abundant mats of over 100,000 square feet each at Manawai (Pearl and Hermes Atoll), outcompeting the species typically living in these ecosystems.
