Oceanography Calculators
Assess marine salinity concentrations, translate oceanic depth parameters to hydrostatic pressure limits, estimate wave dynamics celerity indices, compute chlorophyll biological water color classes, and model thermohaline seawater densities.
Wave State Estimator
Relate Significant Wave Height to wave period, deep water wavelength, celerity (wave speed), and WMO Sea State index.
Wave Characteristics
Oceanographic Core Report
UNESCO 1981 / Medwin modelsDeep water waves become physically unstable and break when steepness exceeds the Michell limit of 1/7 (~0.1428).
Oceanographic calculations use precise equations of state and wave velocity physics. Physical densities adjust dynamically according to temperature and salinity to define thermohaline buoyancy currents.
