Sea spray aerosol production from waves breaking in the surf zone

Sea spray aerosol is a product of wave breaking. A very strong source of this aerosol is the surf zone. In this sense, measurements in the surf zone can be suitable for the assessment of the contributions of the various spray production mechanisms to the total concentrations. At present, a comprehensive data set for performing such measurements...

Characterization of aerosols at a coastal site near Vindeby (Denmark)

Aerosol particle size distributions and aerosol chemical composition were measured with optical particle counters and filter packs, respectively, on an offshore mast in the Danish coastal waters near Vindeby on the island of Lolland. The filter pack samples were analyzed for ions representative of marine and continental aerosol: Na+, Cl-, SC4-,...

Deposition of atmospheric trace elements into the North Sea: Coastal, ship, platform measurements and model predictions

The atmospheric input of up to 16 trace and other elements into the North Sea is further assessed from aerosol concentrations measured at a coastal station in Belgium, on ships during two cruises, and on a platform, in the years 1992 - 1994. The Slinn and Slinn model is used to calculate the dry deposition from the measured aerosol...

Aerosol Production in the Surf Zone

Aerosol production in the surf zone and effects on IR extinction

The aerosol production in the surfzone, as determined from measurements, at two sites along the Califomia coast is presented. The data used were collected during three EOPACE (Electro-Optical Propagation Assessment in Coastal Environments) measurement campaigns in 1996 and 7997. Particle counters were deployed at both the end and the base of two...

Quantitative assessment of surf-produced sea spray aerosol

The first results are presented from a quantitative model describing the aerosol production in the surf zone. A comparison is made with aerosol produced in the surf zone as measured during EOPACE experiments in La Jolla and Monterey. The surf aerosol production was derived from aerosol concentration gradients measured downwind from the surf zone...

Use of radar remote sensing in coastal zone management

This paper, presented in poster form addresses the use of radar remote sensing in coastal zone management. Current and future applications in The Netherlands are highlighted with an outlook to technology and models that are involved. Applications include monitoring of the environment, oil spills, shipping, bottomtopography, coastal erosion. In...

Bubble Size Distributions in Coastal Seas

Bubble size distributions have been measured with an optical system that is based on imaging of a small sample volume with a CCD camera system, and processing of the images to obtain the size of individual bubbles in the diameter range from 30 to lOOO^m. This bubble measuring system is deployed from a buoy which is either self-contained or which...
