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.
Acronyms: XRF = x-ray fluoresencence; RBS = Rutherford
Backscattering; XRD = x-ray diffraction; SEM = scanning electron microscopy; AFM = atomic force microcopy; PES = photoelectron spectroscopy, with x-rays (XPS) and ultraviolet (UPS); KP = Kelvin probe
measurements, SECM = scanning electrochemical microscopy, PL = photoluminescence; FTIR = Fourier transform infrared spectroscopy
Satellite instruments provide global maps of surface UV irradiance by combining
backscattered radiance
measurements with radiative transfer models.
This provides range - and time - resolved
measurements of radial velocity and attenuated
backscatter.
