Monitoring Posidonia oceanica in Tuscany with high-frequency Klein 4900 side‑scan sonar

Co.l.mar Italia recently conducted a technical survey for marine biocenosis monitoring, focusing in particular on the Posidonia oceanica seagrass meadows along the Tuscany coastline.

The survey was carried out using a Klein 4900 side‑scan sonar from Klein Marine Systems, configured to operate at 900 kHz, ideal for acquiring high-resolution acoustic images of the seabed.

The Klein 4900 is a compact and versatile sonar system designed for shallow-water applications. Its main specifications include:

• 445 kHz and 900 kHz operational frequencies

• Up to 150 m side range per side

• High acoustic resolution for detailed surveys

• Compatible with mobile platforms or autonomous underwater vehicles (AUVs/ROVs)

By using this cutting-edge equipment, Colmar delivers top-tier marine environmental monitoring services, providing extremely accurate and reliable results.

The acoustic images obtained allow detailed seabed mapping and identification of Posidonia oceanica meadows, contributing to the protection of marine ecosystems and sustainable coastal area management.

Co.l.mar’s commitment to marine environmental technology translates into effective solutions for public bodies, research institutes, and marine sector operators.
