In previous studies, the impacts of YSWC on the spring bloom were
mainly related to the hydrodynamic environment rather than the nutrients.
Recently, nutrient status during the spring bloomin the central YS
has been reported (Jin et al., 2013). Their results showthat nutrient concentrations
before the spring bloom within the euphotic zone of the
YSWC area are significantly higher than those in the coastal area, and
rapidly decreasing during the blooms (Jin et al., 2013). Similarly, the
decline of nutrients in the central area during April, compared with
