Survey_Scans_with depths.pdf

This document collection consists of sonar survey data and related technical imagery documenting a submerged tree hazard at coordinates 47°54.591 N, 124°38.348 W in a maritime location. The survey was conducted on June 25, 2025, at 07:04:50 AM local time, with water temperature of 52.9°F, depth of 10.0 feet, range of 0.221 nautical miles, and heading of 200 degrees magnetic. The waypoint is identified as "Submerged tree" with event code 2025/06/25EVENTS in a navigation system.

The document includes bathymetric chart data showing depth measurements ranging from approximately 8 feet to 13+ feet across the survey area, with multiple depth readings overlaid on nautical charts. Sonar imagery displays the submerged tree structure in high-resolution format showing water column data, bottom returns, and the distinctive acoustic signature of the wooden obstruction. A geographic reference map indicates the location near Quileute Marina, Alpha Angler Charters, and local waterfront facilities on the Washington coast. Three-dimensional sonar visualization renders display the tree's spatial orientation and size relative to the seafloor. The serial connection notation indicates data processing via PACWAVRSRTCM3 stream at 19200 bps. This technical documentation appears to support marine navigation safety, environmental survey, or coastal hazard mitigation purposes rather than representing a federal contract solicitation or related procurement document.
