Carpenter was a highly renowned scientist who studied fish, co-authoring a 2005 study that crowned the Philippines’ Verde Island Passage as “the center of marine shore fish biodiversity.”

“Dr. Carpenter made groundbreaking contributions that transformed global understanding of Philippine marine biodiversity,” Silliman University said in a statement.
“Dr. Carpenter’s contributions to Philippine marine science were profound and enduring,” a statement the Philippine Association of Marine Science posted Tuesday read.
“As a U.S. Peace Corps volunteer in the 1970s, he worked with the Bureau of Fisheries and Aquatic Resources and helped train the country’s first coral reef science team. His early papers on Philippine coral reef fisheries resources, including his work with National Scientist Angel C. Alcala on muro-ami and kayakas reef fisheries, were landmark contributions that shaped the country’s understanding of reef fisheries and the urgent need for science-based management,” the statement continued.

“In the wake of this devastating loss, PAMS strongly condemns this act of violence. We call upon the Philippine National Police, the local authorities in Negros Oriental, and appropriate national investigative agencies to conduct a swift, thorough, and transparent investigation. Those responsible for this heinous crime must be held fully accountable under the law,” the statement added.
“Dr. Carpenter devoted his life to protecting the Philippines’ marine heritage. We owe it to him to honor that legacy by continuing his work and demanding justice for his tragic and untimely death,” the statement concluded.
