Smartfin, is a surfboard fin with sensors that measures
multiple ocean parameters including salinity, pH, temperature, location, and wave characteristics.
«New satellite method enables undersea estimates from space: Statistical advance quantifies
important ocean parameters in the illuminated ocean.»
This module will ensure accurate, consistent, comparable, regional scale, long ‐ term measurements
of ocean parameters, which are key to addressing urgent societal and scientific challenges such as climate change, ocean ecosystem disturbance, and marine hazards.
These algorithms, developed for national and international operational and research satellite programs, convert sensor / instrument measurements into geophysical parameters such as vertical temperature / water vapor profiles, estimates of cloud amount, type and phase, and land /
ocean parameters such as sea surface winds, net heat flux, and forest fire intensity / extent.
The result is Smartfin, a surfboard fin that houses sensors for measuring multiple
ocean parameters like salinity, pH, temperature, location, and wave characteristics while surfers ride the waves.
Ocean parameters: horizontal and vertical ocean diffusivity k H = 200 — 5,000 -LCB- 2000 -RCB- m2 / s, k V = 0.1 — 1.0 × 10 − 4 -LCB- 0.3 × 10 − 4 -RCB- m2 / s at top, 1.1 — 2.0 × 10 − 4 -LCB- 1.3 × 10 − 4 -RCB- m2 / s at ocean bottom (vertical profile after Bryan Lewis).
