Maritime Situational Awareness: An Exploration

A write-up with links to different versions of impedance buffer and amplifiers for piezoelectric elements.

Underwater communication & navigation laboratory for DIY community with love

An analog amplifier board designed for 2 piezoelectric hydrophones consisting of a preamp, amp, and bandpass filter with 10khz high pass and 60khz low pass spec.

Self-supervised anomaly detection for Ocean Networks Canada underwater acoustic data using SSAMBA and Mamba-based audio representation learning.

Marine bioacoustics detection pipeline

Synthetic underwater acoustic waveforms for self-supervised learning. 12,000 5-second clips at 16 kHz covering 4 vessel classes + no-vessel ambient. Non-overlapping shaft rates, blade-gated cavitation bursts, Knudsen-model sea noise. License: TBD by Altair Infrasec Pvt. Ltd. Contact styagi@oravontsystems.com for details

Dash app for labeling, verifying, and exploring hydrophone detections with spectrograms, audio playback, notes, and time-frequency bounding boxes.

Lista de posibles proyectos de cooperación entre Greencore e Isla del Coco

Python tools for downloading Ocean Networks Canada hydrophone audio and spectral products, checking deployments, and generating custom edge-safe spectrograms.

Simple code I made in python as an amateur in bioacoustics and programming (with a little help from ChatGPT) to analize data from a homemade Hydrophone. Gets clip length, recording frecuency, cuts to 5 minutes, visualizes and saves spectrogram, RMS in re dB, Sound origin and percentage (Physical, Human, Biological) and comparative spectrum
