    The satellite for Argos and AltiKa (SARAL/AltiKa) is the first ocean altimeter mission to operate in the Ka-band frequency. The objective of this article is to investigate the extent to which SARAL/AltiKa sea-level measurements provide valuable information in a complex bathymetric region, i.e., the semienclosed Solomon Sea. The data-editing procedure is revisited, and we propose two new data-editing criteria. The first is based on the detection of erroneous sea-level values after computation, and the second directly analyzes the radar measurements and geophysical corrections. We show that both methods are significantly more efficient than the standard procedure used in operational processing chains.
