Biodiversity in salt marshes builds climate resilience
Biodiversity salt marshes climate resilience
2016/8/23
Coastal ecosystems worldwide are feeling the heat of climate change. In the Southeastern U.S., salt marshes have endured massive grass die-offs as a result of intense drought, which can affect everyth...
An integrated modeling study on the effects of mineral dust and sea salt particles on clouds and precipitation
mineral dust sea salt particles clouds
2011/2/24
This report addresses the effects of pollution on the development of precipitation in clean ("pristine") and polluted ("hazy") environments in the Eastern Mediterranean by using the Integrated Communi...
Different photolysis kinetics at the surface of frozen freshwater vs. frozen salt solutions
Different photolysis kinetics frozen freshwater frozen salt solutions
2010/11/30
Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL) . The p...

2009/3/11
The concentration of cloud condensation nuclei (CCN) in the marine boundary layer (MBL) was estimated from dimethyl sulfide (DMS) flux, sea salt (SS) emission, and aerosols entrained from the free tro...
The origin of sea salt in snow on Arctic sea ice and in coastal regions
sea salt snow Arctic sea ice coastal regions
2009/3/10
Snow, through its trace constituents, can have a major impact on lower tropospheric chemistry, as evidenced by ozone depletion events (ODEs) in oceanic polar areas. These ODEs are caused by the chemis...
