Journal ArticleDOI
Doppler radar measurements of wave groups and breaking waves
TL;DR: In this paper, a 3GHz Doppler radar has been used to study wave dynamics and backscatter from the sea surface at low grazing angles, and it is shown that for a developing sea in deep water, group behavior modulates the occurrence of wave breaking.
Journal ArticleDOI
Aerosol non-sea-salt sulfate in the remote marine boundary layer under clear-sky and normal cloudiness conditions: Ocean-derived biogenic alkalinity enhances sea-salt sulfate production by ozone oxidation

TL;DR: In this paper, Baring Head, New Zealand, samples were collected during clear-sky and normal cloudiness conditions to assess the contribution that the O3 oxidation mechanism may make to coarse NSS.
Journal ArticleDOI
Switching system for single antenna operation of an S-band FMCW radar
TL;DR: A ground based S-band ocean surface remote sensing FMCW radar that has been adapted for single antenna operation by alternately switching the single antenna between the transmitter and the receiver is described.
Journal ArticleDOI

TL;DR: The SOLAS air-sea gas exchange experiment (SAGE) as mentioned in this paper was a multiple-objective study investigating gas transfer processes and the influence of iron fertilisation on biologically driven gas exchange in high-nitrate low-silic acid low-chlorophyll (HNLSiLC) Sub-Antarctic waters characteristic of the expansive subpolar zone of the southern oceans.
Journal ArticleDOI
Uncertainties in gas exchange parameterization during the SAGE dual-tracer experiment
TL;DR: In this paper, a dual tracer experiment was carried out during the SAGE experiment using the inert tracers SF6 and 3He, in order to determine the gas transfer velocity, k, at high wind speeds in the Southern Ocean.
