“…During this time period, the warm and oligotrophic Kuroshio surface water intrudes through the Luzon Strait and occupies a large area of the NSCS basin (Shaw, 1991;Hu et al, 2000), which significantly reduces the nutrient inventory in the upper ocean (Du et al, 2013). The TWS is ∼ 180 km wide with an average depth of ∼ 60 m (Hong et al, 2011). Except in the winter monsoon period, the northward flow dominates (Wu and Hsin, 2005;Jan et al, 2006).…”

Inter-shelf nutrient transport from the East China Sea as a major nutrient source supporting winter primary production on the northeast South China Sea shelf

Abstract. The East China Sea (ECS) and the South China Sea (SCS) are two major marginal seas of the North Pacific with distinct seasonal variations of primary productivity. Based upon field observations covering both the ECS and the northern SCS (NSCS) during December 2008-January 2009, we examined southward long-range transport of nutrients from the ECS to the northeastern SCS (NESCS) carried by the China Coastal Current (CCC) driven by the prevailing northeast monsoon in wintertime. These escaped nutrients from the ECS shelf, where primary production (PP) was limited in winter, might however refuel the PP on the NESCS shelf at lower latitude, where the water temperature remained favorable, but river-sourced nutrients were limited. By combining the field observation of nitrate+nitrite (NO 3 +NO 2 , DIN) with our best estimate of volume transport of the CCC, we derived a first-order estimate for DIN flux of 1430 ± 1024 mol s −1 . Under the assumption that DIN was the limiting nutrient, such southward DIN transport would have stimulated 8.84 ± 6.33 × 10 11 gC of new production (NP), accounting for 33-74 % of the NP or 14-22 % of PP in winter on the NESCS shelf shallower than 100 m.

“…The Strait's climate is sensitive to large-scale interannual variations originating in the Tropical Pacific Kuo and Ho 2004). The Strait is a meeting place and a conduit of warm waters of the Kuroshio and SCS, and cold waters of the China Coastal Current (CCC) (Jan et al 2002;Hong et al 2011;Fig. S1 in online supplementary material), with a strong north-south gradient of sea surface temperature (SST), especially in winter (Fig.…”

“…SST did not decrease much in Bins 13, 14 and 16 because they are located near the LZS, where were influenced by the Kuroshio warm water westward flow (red arrows in Figure 10) to this sea area (about 119 E, 20 N) in winter (Metzger & Hurlburt 1996;Liang et al 2008, Hong et al 2011aChang et al 2009Chang et al , 2013Liao et al 2013). Mainly due to the contribution of the Kuroshio intrusion water (KIW) (as Figure 10), suitable temperature with average value of 22.42 C in the offshore waters after the snowstorm provided favourable environment for the growth of phytoplankton, which would be beneficial for the further elevation of Chla.…”

“…This precipitation and the dissolved water from the ice and snow formed colder and larger fresh water runoff that pooled mainly into the PR and intensified the discharge of the PRE, as can be confirmed by noting that the largest discharge with the lowest temperature from PRE for the period 2006-2012 occurred in February 2008 after the snowstorm (Figure 4(b,c)). The larger and colder PRE diluted water flowed into NSCS, whose intrusion of larger and colder PRE diluted water extended mainly to the southwest and partly to the southeast (Hong et al 2011a;Lu et al 2013). This larger and colder PRE diluted water and its extension caused the SST to decline further in the study area, especially in the coastal waters near the PRE (Figure 4(b)).…”

At the beginning of 2008, disastrous weather with snowstorms truck South China. Analysis of satellite and in situ data revealed obvious changes in ecological environments in the northern South China Sea after snowstorms. The sea surface temperature (SST) data from NOAA and Moderate Resolution Imaging Spectroradiometer (MODIS) from 2000 to 2013, and the chlorophyll-a (Chla) concentration from MODIS are analysed. In the study area, the multiple-day-averaged SST dropped by 20.01% and Chla concentration increased by 22.42% during and after snowstorm. SST decreased more significantly and Chla increased in the coastal waters, while suspended sediment concentration (SSC) increased more remarkably offshore. The biggest drop of SST reached 6 C and striking elevation in Chla with 52.55% in the Taiwan Strait, and SSC changed significantly near to the Taiwan bank after the snowstorm. Further analysis indicated that the remarkable reductions in SST were caused by large cold water input from Min-Zhe coastal water and the Pearl River Estuary, as a result of strong sea-land-air interaction in the coastal waters during the snowstorm. The increase in Chla may be related to the abundant nutrients from the plenty of cold water, a strong front and vertical mixing in the coastal waters.
