Field Activity 2026-303-FA

Identifier 2026-303-FA
Alternate names 26BIM03 = WVR1; 26BIM04 = WVR2
Purpose To collect 2026 pre-hurricane season bathymetry for Midnight Pass and Milton Pass that were created by the 2024 storms Helene and Milton. Updated bathymetry is needed to support annual monitoring efforts of the geomorphological changes in the pass and track sediment distribution patterns. The R/V G. Hill will be support vessel to the PWCs.
Location Midnight Pass is located Siesta Key, FL; Milton Pass is located in Englewood, FL
Info derived 2026 bathymetry x,y,z data points, 2026 digital elevation models, 2026 trackline dataset. This information will also be applied in other analysis.
Comments Funding account is Hurricane Ian Supplemental and the account to use is GX23MN00V02FL26. R/V Scooby and R/V Shaggy are the new PWCs that are planned to be used for this survey. That information will be added to Compass as soon as they come on-line. For now, R/V Shark and R/V Chum are stand-ins. Entries for this field activity are based on entries from Field Activity 2025-313-FA.
Projects
Platform
