Intrusion of Kuroshio Helps to Diminish Coastal Hypoxia in the Coast of Northern South China Sea

评论：可以考虑用Kuroshio Intrusion(更加紧凑)。Help + verb (不需要to)。Coastal Hypoxia of Northern South China Sea就可以了。

Since half a century ago, the number and area of dead zones (dissolved oxygen (DO) < 2 mg L^–1 or 30% saturation) in the coastal oceans has increased dramatically. 

评论：应该是have。

As widely recognized, the increased terrestrial nutrient and organic matter inputs are the two main factors causing the eutrophication of many coastal oceans. 

Here we show with decadal observed time series data from stations off the Pearl River Estuary and in the northern South China Sea (nSCS) that a strong intrusion into the nSCS of the West Philippine Sea (WPS) seawater in the form of Kuroshio branch occurred during the warm phase of the Pacific Decadal Oscillation (PDO) around 2003–2004 and 2015–2016 (also a strong El Niño event). 

评论：这个句子太长了。在  we show that中间插入“一串东西”，不常见。

Consequently, the DO concentration increased but NO₃^– and PO₄^3– concentrations decreased in the subsurface layers of the nSCS. 

The WPS seawater was observed to reach the hypoxic area off the Pearl River Estuary in 2003–2004. 

Likely, due to the oxygen supply carried by the Kuroshio, little hypoxia developed. 

Yet, anoxic condition developed in the cold phase of PDO or strong La Niña years with weak Kuroshio intrusions.
