Other tools in the researchers» arsenal were high - resolution tracking, which provided information about how the manta rays used the lagoon habitat over long and short periods of time; an acoustic camera, which logged patterns of the animals entrances and departures from the lagoons; and photo identification / laser photogrammetry — making measurements from photographs — which provided insight into whether the manta rays were staying in this habitat for longer time periods by tracking their comings and goings.

They employed a broad spectrum of methods and other measurement data, including Baryonic Acoustic Oscillations, which are density waves from the early universe, local measurements of the Hubble constant, which specifies the universe's rate of expansion at the present day, as well as a certain group of supernovae or exploding stars.

In this study, the researchers, in collaboration with Cranfield University and the Scottish Universities Environmental Research Centre (SUERC), used acoustic thermometry to make the measurement by building an acoustic resonator and making amazingly precise measurements of the speed of sound in argon gas.

These methods are called «acoustic - phonetic» because they combine measurements obtained by listening (acoustic) with the output of automated sound analysis (phonetics).

To quantify krill biomass and distribution we used: an integrated MOCNESS [17] for estimates of krill size and acoustic target strength; dual EK - 60 fisheries echosounders (38 and 120 kHz, Kongsberg - Simrad) calibrated according to [18] and mounted on a zodiac for fine scale (100 km) measurements of acoustic volume backscattering; and the ADCP echo intensity to define the meso - scale (101 km) geographic extent of the krill distributions.

The combination of temperature dependent micro-Raman and femtosecond reflectivity measurements allows for a complete decoupling of the effects of temperature, geometry, and strain on the acoustic phonon dynamics [2, 3].

Recently developed, in - situ techniques for direct volume determination, acoustic wave velocity measurements, and x-ray diffraction at HPCAT, along with molecular dynamics simulations, were employed to explore the nature of the unusual and pressure - tunable, compression and elastic properties.

Generalised linear mixed models (GLMMs) were used to assess the effect of prosody (dog - directed / adult - directed); content (dog / adult) and content — prosody matching (matched (experiment 1) / mismatched (experiment 2)-RRB- on the acoustic measurements of stimuli in experiments 1 and 2.

In the majority of cases, ebullition was measured with funnels or was lumped with diffusive flux via floating chamber measurements; however, in two studies, researchers estimated methane fluxes via eddy covariance (Eugster et al. 2011, Deshmukh et al. 2014), and in another two studies, researchers estimated ebullitive flux via acoustic methods (DelSontro et al. 2011, 2015).

Although we did not explicitly address the temporal or spatial resolution of emission data from each system, it is notable that the few published acoustic and eddy covariance - based reservoir CH4 flux estimates are quite high compared to the median CH4 flux estimates from less temporally and / or spatially integrated measurement techniques (figure 1).
