Does NOAA publish any real-time or near-real-time seafloor point cloud data?
Determining the availability of real-time or near-real-time seafloor point cloud data from NOAA requires careful consideration. While the National Centers for Environmental Information (NCEI) archives extensive multibeam bathymetric surveys, current practices primarily involve post-processing, resulting in a delay before public release. Presently, a live or near-live data feed for survey data does not exist. Coverage for recent surveys largely prioritizes U.S. Exclusive Economic Zone (EEZ) and coastal regions, though broader data acquisition efforts are ongoing.
4,100-km Fibre Cable Across Drake Passage Could End Antarctica’s Hard-Drive Data Runs
A groundbreaking feasibility study by Chile's Subtel indicates a technically viable solution to Antarctica’s data transfer challenges: a 4,100-km fiber optic cable across the Drake Passage. Currently, Antarctic research relies on physically transporting data via hard drives, a slow and resource-intensive process. This proposed connection promises real-time data transmission, accelerating scientific discovery and bolstering climate research. For context on the importance of continuous monitoring, see our article, "Wuthuga (dugong) population status in Gathaagudu (Shark Bay) sea country," highlighting the challenges of tracking wildlife populations.
Kalman filter for ocean waves using IMU
A novel Kalman filter implementation for real-time ocean wave and boat motion estimation has been developed and validated using an inertial measurement unit (IMU). Utilizing an OU-Driven Quaternion MEKF framework, this open-source project, ‘ocean-imu’ (available on GitHub), provides calibrated estimates of boat heave and wave direction leveraging the atomS3R unit. This innovative approach offers researchers and practitioners a valuable tool for marine navigation and oceanographic data acquisition.
