Marine & Surf Forecast API
Marine- und Surfvorhersagen als API, powered by Open-Meteo — sauberes JSON, kein API-Key. Rufen Sie den aktuellen Meereszustand sowie die stündliche und tägliche Wellenvorhersage für jede Küstenlinie per Breitengrad/Längengrad oder einfach per Ortsnamen ab: signifikante Wellenhöhe, Periode und Richtung, plus die Dünungs- und Windwellenkomponenten separat ausgewiesen, sowie tägliche Maxima und Hauptrichtungen. Ein integrierter Geocoding-Helfer wandelt einen Ortsnamen in Koordinaten um. Vorhersagen laufen bis zu zehn Tage im Voraus. Live-Vorhersagedaten direkt aus dem marinen Modell von Open-Meteo. Ideal für Surf-Report-Apps, Segel- und Bootstools, Küsten- und Meeresbetriebs-Dashboards sowie Strand-Widgets. 4 Datenendpunkte. Authentifiziert mit einem x-oanor-key; Fair-Use-Ratenlimits pro Plan.

Sea Horizon API
Sea-horizon and visibility maths as an API, computed locally and deterministically — the distance-to-horizon, geographic-range and dip numbers a mariner, coastal navigator or marine app works sightings with. The horizon endpoint gives the distance to the sea horizon ≈ 1.169·√(height of eye in feet) nautical miles, including the standard atmospheric refraction that bends the line of sight a little past the geometric edge — at 9 ft of eye height the horizon is about 3.5 nm off — together with the dip, how far below true horizontal that watery edge lies (≈ 0.97′·√h), the correction subtracted from a sextant altitude shot to the sea horizon. The geographic-range endpoint gives how far off a light or landmark first peeps over the horizon = the sum of two horizon distances, your own plus the object's: 1.169·(√h_eye + √h_object), so a 100 ft lighthouse from a 9 ft cockpit lifts above the sea at about 15 nm — purely geometric, before the light's own luminous range and the visibility. The object-height endpoint inverts it: how tall a tower, light or headland must stand to break the horizon at a target range, or how close you must be before a known landmark appears. Everything is computed locally and deterministically, so it is instant and private. Ideal for marine-navigation and chartplotter apps, coastal-pilotage and lighthouse tools, and sailing utilities. Pure local computation — no key, no third-party service, instant. Geometric/refraction model. 3 compute endpoints. For great-circle distance use a geo-distance API; for set & drift a set-and-drift API.

Set and Drift API
Current-sailing (set and drift) navigation maths as an API, computed locally and deterministically — the course-over-ground, course-to-steer and current numbers a mariner, navigator or marine app plots a passage with. The course-made-good endpoint adds the boat's velocity through the water to the current vector to give the real track: the course over ground (COG) and speed over ground (SOG), with the drift angle the current pushes you off your nose — steering 090° through the water at 10 knots with a 2-knot current setting north comes out around 079° over the ground at 10.2 knots. The course-to-steer endpoint solves the other way: the heading to steer to make good a desired ground track, steering up-current to cancel the across-track set (sin(H−T) = −drift·sin(set−track) ÷ speed), and the resulting SOG — usually slower into a current, faster with it astern, and impossible if the current across the track beats your speed. The current endpoint finds the set and drift from the offset between a dead-reckoning position and an observed fix: the set is the bearing DR-to-fix and the drift is that distance ÷ the elapsed time, ready to carry forward. Everything is computed locally and deterministically, so it is instant and private. Ideal for marine-navigation and chartplotter apps, sailing and boating tools, and maritime-training utilities. Pure local computation — no key, no third-party service, instant. Degrees true. 3 compute endpoints. For great-circle distance use a geo-distance API; for tide times a tides API.

Seawater API
Seawater oceanography maths as an API, computed locally and deterministically from the standard equations — the density, freezing-point and chlorinity numbers an oceanographer, marine scientist or aquarist works with. The density endpoint gives the seawater density and σt from salinity and temperature using the full UNESCO EOS-80 one-atmosphere equation of state — it reproduces the official check value of 1027.675 kg/m³ at 35 PSU and 5 °C exactly — around 1,025 kg/m³, rising with salinity and falling with temperature, the two drivers of the ocean's density-driven circulation where cold salty water sinks. The freezing-point endpoint gives the freezing point from salinity (Millero): about −1.9 °C at the ocean's typical 35 ppt, and because salt also pushes the temperature of maximum density below freezing, seawater keeps overturning and cooling all the way down instead of stratifying like a freshwater lake — why the open ocean rarely freezes outside the polar seas. The chlorinity endpoint converts between salinity and chlorinity through the Knudsen relation S = 1.80655 × Cl, the classic titration measure that the constant major-ion proportions of seawater make reliable. Everything is computed locally and deterministically, so it is instant and private. Ideal for oceanography and marine-science tools, ocean-model and sensor pipelines, aquarium and aquaculture apps, and environmental dashboards. Pure local computation — no key, no third-party service, instant. Surface (atmospheric-pressure) forms. 3 compute endpoints. For the speed of sound in seawater use a sonar API; for general colligative properties a colligative-properties API.

Sonar & Underwater Sound API
Unterwasserschall- und Sonar-Mathematik als API, lokal und deterministisch berechnet – die Geschwindigkeits-, Absorptions- und Entfernungszahlen, mit denen ein Schiffsingenieur, Sonarentwickler oder Ozeanograph arbeitet. Der Schallgeschwindigkeits-Endpunkt liefert die Schallgeschwindigkeit im Meerwasser aus der Mackenzie-Neun-Term-Gleichung: etwa 1.500 m/s – weit schneller als in Luft – steigend mit Temperatur, Salzgehalt und Tiefe, sodass ein Profil von 25 °C, 35 ppt bei 1.000 m 1.550,7 m/s ergibt. Da die Geschwindigkeit mit der Tiefe variiert, biegen sich Schallstrahlen und bilden den SOFAR-Kanal, der Walgesänge und Signale über ganze Ozeane trägt. Der Absorptions-Endpunkt liefert Thorp's Schallabsorptionskoeffizienten in dB pro km gegen die Frequenz, mit dem Verlust über eine Strecke: Meerwasser verschluckt hohe Frequenzen schnell, weshalb Langstreckensonar und Walrufe tief sind, während hochfrequentes Sonar nur auf kurze Distanz scharfe Bilder liefert. Der Echo-Entfernungs-Endpunkt wandelt die Zwei-Wege-Laufzeit eines Echolots oder Sonars in die Entfernung oder Tiefe um – Distanz = Schallgeschwindigkeit × Zeit ÷ 2 – sodass ein Ein-Sekunden-Rundweg bei 1.500 m/s ein Ziel 750 m entfernt ergibt, dessen Genauigkeit auf der angenommenen Schallgeschwindigkeit beruht. Alles wird lokal und deterministisch berechnet, also sofort und privat. Ideal für Sonar- und Hydrophon-Werkzeuge, Vermessungs- und Bathymetrie-Apps, ozeanakustische Forschung und AUV/ROV-Navigationshilfen. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Standardgleichungsschätzungen über ihre gültigen Bereiche. 3 Compute-Endpunkte. Für die Schallgeschwindigkeit in Luft und Mach verwenden Sie eine Mach-Zahl-API; für Dezibel eine Schallpegel-API.
