In June 2025, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted sediment core sampling at Midnight Pass, an inlet between Siesta Key and Casey Key, Florida. This inlet was closed by mechanical action in 1983 and reopened by the passage of hurricanes Helene and Milton in 2024, reconnecting Little Sarasota Bay to the Gulf of America (Gulf of Mexico). A total of seven cores were collected, with approximate recovery lengths between 0.54 meters (m) and 1.05 m. The cores were collected using a mechanical post driver and 3-inch (7.62 centimeters [cm]) diameter aluminum barrels.
