Abstract
In order to understand the processes governing the production of
marine aerosols, repeatable, controlled methods for their generation are
required. A new system, the miniature Marine Aerosol Reference Tank
(miniMART), has been designed after the success of the original MART system,
to approximate a small oceanic spilling breaker by producing an evolving
bubble plume and surface foam patch. The smaller tank utilizes an
intermittently plunging jet of water produced by a rotating water wheel, into
an approximately 6 L reservoir to simulate bubble plume and foam formation
and generate aerosols. This system produces bubble plumes characteristic of
small whitecaps without the large external pump inherent in the original MART
design. Without the pump it is possible to easily culture delicate planktonic
and microbial communities in the bulk water during experiments while
continuously producing aerosols for study. However, due to the reduced volume
and smaller plunging jet, the absolute numbers of particles generated are
approximately an order of magnitude less than in the original MART design.
