Dr. Quint White is marking 50 years at Jacksonville University this September, a half-century career that reshaped marine science across Northeast Florida and left lasting marks on the Beaches coastline.

A Florida Times-Union photo gallery published Aug. 29, 2026, documented the milestone with images spanning White's career, including fieldwork in Atlantic Beach salt marshes and the site of a planned OCEARCH shark research headquarters in Mayport Village.

White, now professor emeritus, arrived in Jacksonville on Sept. 3, 1976, as a visiting assistant professor on a two-year appointment, replacing a colleague on leave. He had been hired just two weeks earlier. He walked into his first class at 8 a.m. on Labor Day, Sept. 6, 1976, without a class roster or his copy of the textbook, he wrote in a Nov. 5, 2024, Florida Times-Union column.

The two-year gig became a half-century career.

When a colleague asked White to start a marine biology major, he agreed on one condition: it had to be marine science. Understanding the ocean required chemistry, physics and math alongside biology, he wrote in the column.

By 2010, that insistence had grown into the Marine Science Research Institute (MSRI), a $10 million, 32,000-square-foot facility on the St. Johns River that houses the offices of the St. Johns Riverkeeper and Florida Fish and Wildlife, according to Jacksonville University. White served as executive director from its opening until he retired in August 2024.

His research took him into the salt marshes off the Intracoastal Waterway near Atlantic Beach, where he was photographed conducting fieldwork in May 2000. He also wrote a monthly "River Life" column in the Times-Union covering the science, history and ecology of the St. Johns River.

White's reach extended to Mayport. In 2017, he and JU President Tim Cost partnered with OCEARCH, described as the world's largest shark-tagging and oceanic research organization. OCEARCH founder Chris Fischer became Explorer in Residence at JU.

On June 16, 2023, JU and OCEARCH announced $5 million in state funding for an OCEARCH Global Headquarters in Mayport, planned for 1.18 acres of waterfront at the mouth of the St. Johns River. The facility would include a marine life research laboratory, public education space, dockage for research vessels and housing for crew members. A concrete dock funded by the City of Jacksonville was under construction at the site as of that June 2023 announcement. JU and OCEARCH expected to break ground by 2024, though the facility's current status has not been publicly confirmed.

As of June 2023, OCEARCH had conducted 45 ocean research expeditions and produced more than 80 peer-reviewed scientific publications. JU students and faculty had joined 11 of those expeditions.

JU honored White with its Marine Science Pioneer Award on Oct. 24, 2024. Past recipients include Dr. Robert Ballard, discoverer of the Titanic, and OCEARCH founder Fischer. An endowed graduate fellowship in White's name, initiated by former mentee Mike Hand and Susan Hand, had raised more than $180,000 as of the ceremony.

"I've never really felt like a pioneer. I've always enjoyed what I'm doing," White said at the Oct. 24, 2024, ceremony, according to JU. He called himself "very, very fortunate" to have spent his career doing work he loved.

The fellowship bearing White's name will fund the next generation of JU marine science graduate students. No public events marking the 50th anniversary have been announced.
