I gingerly followed Mark out through the channel there, intimidated by the wind, the freezing water, and, above all, the heavy-gauge waves plunging and grinding down the rock reef.
The anglers, in waders and baseball caps, some smoking cigarettes, scanned the waters below for telltale splashes, while the surfers gauged the wave breaks as white ribbons of foam swept toward shore.
Near-shore gauges include wave gauges using ultrasonic waves and GPS buoys.
To accurately measure the in situ elastic modulus (E = 2(1 + ν)ρVs2) for nondestructive quality assessment of asphalt pavements, field measurements of density via an electromagnetic gauge and shear-wave velocity (Vs) via surface-wave testing were examined for four paving projects covering a range of mixes and traffic loads.
A virtual wave gauge (VWG) technique based on stereo imaging is developed to remotely measure water wave height, period, and direction.
Black squares with numbers correspond to wave gauge used for numerical simulations (Supplementary Table 4).
(b) The tsunami waveforms recorded by the bottom pressure gauge (TM1), GPS wave gauge and coastal tide gauge [72].
a The green squares and triangles show the location of the coastal tide gauge and offshore wave gauge stations, respectively.
We conducted a tsunami waveform inversion analysis of the tsunami signal recorded at seven tide gauges and two wave gauge stations.

Three offshore gauges, one GPS wave gauge (Iwate S at ~200 m water depth) and two cabled pressure-gauges (TM-2 at ~1,000 m and TM-1 at 1,600 m depth), recorded the two-stage tsunamis (Fig. 2).
