Satellite Synthetic Aperture Radar (SAR) observations can provide a global view of ocean swell fields when using a specific ”wave mode” sampling. A methodology is presented to routinely derive integral properties of the longer wavelength (swell) portion of the wave spectrum from SAR Level 2 products, and both monitor and predict their evolution across ocean basins. SAR-derived estimates of swel...

The questions of how wind and ocean waves interact and how this coupling should be parameterized to optimally derive the surface wind stress remain open and central to estimating air-sea coupling at the global and local scales. While much attention has been given to evaluating the effect of the wind-driven waves upon the surface wind stress and air-sea drag coefficient, less emphasis has been g...

Microgels are cross-linked polymer latex particles that can form stable colloidal dispersions. Their typical sizes range from 10 to 1000 nm and they can swell in response to their external environment (pH, temperature and solvency). This swelling behaviour is central to many potential applications for microgels. The existing literature is dominated by studies of the properties of aqueous microg...

About 40 years ago, Snodgrass and other oceanographers (1966) tracked ocean swell propagating across the entire Pacific Ocean. At about the same time, several investigators (including Benjamin and Feir) showed that a uniform train of plane waves of finite amplitude on deep water is unstable. Comparing these two results, each of which is highly cited, leads to the following question: in light of...

Nonlinear Processes Geophysics, NPG-16Ocean Swell within the kinetic equation for water waves Zakharov and Badulin The authors present interesting notions about swell evolution for long durations and it seems worth publishing. Based on my considerations I recommend a major review. There are 3 important notions that should be discussed or modified in more detail. One concerns the model setup use...

The molecular identity of the channels producing swelling-activated Cl conductance (g swell) is of great interest since this physiologic response to swelling is common to many cells. the question of whether the observed g swell represents a family of channel proteins is presently unanswered, but to be included in this family a channel must be activated by cell swelling and conduct Cl. Determini...

development of argillic horizon in loess derived soils under xeric and udic soil moisture regimes was studied in golestan province. soils were classified as hapludalfs and haploxeralfs. high leaching, stability of the surface, forest vegetation,structure and well drainage conditions provide appropriate conditions for clay migration through the profile and formation of argillic horizons. in the ...
