No cost extension was granted through 3/1/24. This project involves two short-term employees engaging in recreational SCUBA diving expeditions at a minimum of eight SCUBA diving businesses across a 100-mile region of southeast Florida. Due to unforeseen delays in the hiring process, their participation didn’t commence until the second week of October, significantly setting back the project’s timeline. The delay, exceeding six weeks, has been exacerbated by factors such as inclement weather, the employees’ health and fitness status for diving, and the availability of dive shops for scheduling. An extension is requested to accommodate the completion of the recreational SCUBA diving trips, after which data collation and final report writing will ensue.
