Title
Sea Surface Salinity Remote Sensing
Subject
Sea, Ocean, Science, Technology
Description
Sea surface salinity (SSS) is an essential climate variable [1]. It is a key component of the water cycle,
as a tracer of precipitation and evaporation, river outflow and ice melt/freeze. It is a key driver of oceanic
circulation through its role in ocean density. It is also a critical parameter for understanding the variability
of ocean carbon fluxes, providing information on water masses and of their chemical properties.
In situ SSS observation coverage is lacking due to limited accessibility and the rough environment
of most oceanic regions, which limits long term deployment and maintenance of in situ instruments.
The lack of long term observations with good spatial coverage is exacerbated in the high latitude oceans
such as the Arctic and the Southern Oceans. Since the year 2000, the number of in situ observations
and their spatial and temporal coverage have increased substantially with the deployment of the
Argo network of free drifting profiling floats [2]. There are now approximately 4000 Argo floats
deployed globally that measure conductivity, temperature and depth/pressure (CTD), from which
vertical profiles of salinity and temperature are retrieved from 2000 m deep to 5-10 m below the surface.
Despite the continuous deployment of Argo floats and other sensors in the global oceans, spatial and
temporal coverage remains sparse in many regions, and combining satellite and in situ measurements
is necessary to derive an overview of the complete system.
SSS in the open ocean has been monitored from space since 2010 by the European Space Agency’s
Soil Moisture and Ocean Salinity (SMOS) [3] mission, the National Air and Space Administration
(NASA) and Comisión Nacional de Actividades Espaciales’s Aquarius/SAC-D mission [4,5], and more
recently by NASA’s Soil Moisture Active Passive (SMAP) mission [6,7]. This special issue gathers
contributions on research related to various aspects of remote sensing of sea surface salinity and the
combined use of satellite SSS with other observations.
