## Tools (as reported by the server, not verified)

- `resolve\_place`: Turn a place name \('outside Halifax', 'Strait of Hormuz', 'Bergen, Norway'\) into water coordinates. Maritime gazetteer first \(ports resolve to their approaches, straits/seas to a representative point\), then OpenStreetMap. Points on land or shallower than min\_depth\_m are walked seaward along the gaze
- `get\_bathymetry`: Seafloor depth from Clairwave-served global bathymetry \(\~450 m resolution\). Location: lat/lon or \`place\` \(name resolved to a water point, echoed in \`location\`\). Without a bearing: depth at the point. With a bearing \(compass degrees, 0 = north\): a depth profile along that transect out to range\_km.
- `get\_sound\_speed\_profile`: Seasonal sound-speed profile c\(z\) at a location \(lat/lon or \`place\` name, e.g. "Halifax approaches"\) for a calendar month \(1-12\), from Clairwave-served seasonal temperature/salinity climatology, plus the seabed parameters \(compressional/shear speed, density ratio, attenuation, sediment type\) at the
- `run\_transmission\_loss`: Run a physically grounded transmission-loss simulation \(RAM parabolic equation\) from a source at \(lat, lon or \`place\`, depth\) along a compass bearing. Bathymetry, the seasonal sound-speed profile \(\`month\`\) and seabed parameters are fetched for the location automatically. Returns TL vs range at the r
- `estimate\_detection\_range`: Sonar detection range along a bearing from a location \(lat/lon or \`place\`\). Transmission loss \(TL\) is ALWAYS computed: RAM parabolic equation with the location's bathymetry, seasonal sound speed \(\`month\`, default: current month\) and seabed. Every other sonar-equation term is optional — anything not
- `run\_bellhop\_volume`: Full 3D transmission-loss volume around a source \(lat/lon or \`place\`\) with Bellhop \(all bearings\), stored on the platform under a run id. Show \`open\_url\` to the user as a clickable link: it opens this run visualized. Returns the run id, the replication metadata \(SSP, seabed, bounding box\) and file l
- `search\_vessels`: Search live AIS vessels by name or MMSI prefix \(global feed\).
- `vessels\_near`: Live AIS vessels within radius\_km of a point \(lat/lon or \`place\`\), nearest first, with position, course/speed, type, dimensions and last-update time.
- `get\_vessel`: Everything about one vessel: live AIS position/track and static particulars, plus its 3D model \(unique photo-derived model if generated, else the class archetype\) with GLB URL \(bow=+Z, up=+Y\) and platform links.
- `vessel\_source\_level`: Underwater radiated-noise source level of a ship \(monopole, dB re 1 uPa m, 6 m reference source depth\): decidecade spectrum \(10 Hz - 100 kHz; model bands to 31.5 kHz, validated 20 Hz - 20 kHz\) and broadband level, from the JOMOPANS-ECHO reference spectrum model \(MacGillivray & de Jong 2021, J. Mar.
- `get\_vessel\_photo`: Photograph of a vessel from Wikimedia Commons, with attribution.
- `habitat\_received\_level`: Broadband received level \(dB re 1 uPa\) at a fixed site — a fish farm, reef, hydrophone or marine protected area — from the ships around it, power-summed. Each vessel's source level comes from its AIS class, speed and size; transmission loss is a fast broadband model, so this is a screening estimate
- `about`: What Clairwave provides, which models/data back each tool, and limits.
