Determination of wave slopes from photographs of the ocean surface: a new approach
Abstract:
A general nonlinear technique is described for determining wave slopes from photographs of an area of the ocean surface that is illuminated by diffuse skylight. This technique is evaluated using uniform, overcast, and bright sky radiance distribution models, and results from its use are compared with the approximate results obtained by previous authors. Under certain clearly defined practical experimental conditions, it is theoretically possible to determine the total wave slope magnitude at the ocean surface.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
