task1_stable-isotopes Task 1: Stable N and O isotopes of nitrate in Hong Kong waters

The stable N and O isotopes (δ15N and δ18O ) of nitrate (NO3–) showed a clear spatial gradient around Hong Kong and indicated that significant nitrate assimilation is taking place in the southern waters of Hong Kong.

hkust_zq Velocity vectors and cross-isobath component

The first row illustrates the velocity vectors in the upper (0-10m), intermediate (10-20 m) and lower (below 20 m) layer of the water column.

cityu First molecular insight about PFBS toxicology on thyroid

We found that parental exposure of marine medaka to PFBS caused potent disruption of thyroid endocrine system across three generations (F0, F1 and F2)……
