Given a forward horizontal speed of 0.25 ms-1, gliders can cover ~ 25 km per day. They trace sawtooth profiles in the ocean by changing buoyancy, observing subsurface temperature, conductivity, and other water properties versus depth, and at the surface, fix position via Global Positioning System. Onshore team monitor and direct glider trajectories using two-way Iridium satellite communications, which permit near real-time delivery of observations and re-direction of mission/adaptive sampling. NCSU Ocean Observing and Modeling Group group has been running glider surveys in the South Atlantic Bight on a seasonal basis. Active research are being carried out to assimilate glider data along with other coastal ocean observations (satellite SST and SSH, mooring time series, HF Radar surface currents) into high resolution regional ocean model using advanced variational data assimilation schemes, providing a new look at along-shelf and cross-shelf exchanges associated with Gulf Stream dynamics.}, booktitle={Oceans 2016 - shanghai}, publisher={IEEE}, author={He, R.

Deltaic deposits exhibit contrasting characteristics along different sides of the delta plain (South China Sea, SCS hereafter, to the east and Gulf of Thailand, GOT hereafter, to the west) as well as on and off the subaqueous deltaic system. On one hand, cores recovered from the subaqueous delta in the SCS/GOT are consisted of poorly/well sorted sediments with similar/different clay mineral assemblage with/from Mekong sediments. Excess 210Pb profiles, supported by 14C chronologies, indicate either “non-steady” (SCS side) or “rapid accumulation” (GOT side) processes on the subaqueous delta. The δ13C and C/N ratio indicate a mixture of terrestrial and marine-sourced organic matter in the deltaic sediment. On the other hand, cores recovered from areas with no deltaic deposits or seaward of the subaqueous delta show excess 210Pb profiles indicating “steady-state” accumulation with a greater proportion of marine-sourced organic matter. Core analysis’s relevance with local depositional environment and previous acoustic profiling are discussed.}, journal={Journal of Asian Earth Sciences}, publisher={Elsevier BV}, author={Xue, Zuo and Liu, J.

Comparisons with limited observations showed that the model simulation captured the regional patterns and temporal variability of surface wave, sea level, and suspended sediment concentration reasonably well. Significant seasonality in sediment transport was revealed. In summer, a large amount of fluvial sediments was delivered and deposited near the Mekong River mouth. In the following winter, strong ocean mixing, and coastal current lead to resuspension and southwestward dispersal of a small fraction of previously deposited sediments. Model sensitivity experiments (with reduced physics) were performed to investigate the impact of tides, waves, and remotely forced ambient currents on the transport and dispersal of the fluvial sediment. Strong wave mixing and downwelling-favorable coastal current associated with the more energetic northeast monsoon in the winter season are the main factors controlling the southwestward along-shelf transport.}, journal={Continental Shelf Research}, publisher={Elsevier BV}, author={Xue, Zuo and He, Ruoying and Liu, J.Paul and Warner, John C.}, year={2012}, month={Apr}, pages={66–78} } @article{xue_liu_ge_2011, title={Changes in hydrology and sediment delivery of the Mekong River in the last 50 years: connection to damming, monsoon, and ENSO}, volume={36}, number={3}, journal={Earth Surface Processes and Landforms}, author={Xue, Z. and Liu, J.

High-resolution seismic profiling and coring during 2006 and 2007 cruises revealed a low gradient, subaqueous delta system, up to 20 m thick, surrounding the modern Mekong River Delta (MRD) in the west of the South China Sea. Based on clinoform structure, grain size, 210Pb, AMS 14C, and δ13C results, the subaqueous delta is divided into four zones defined by different sedimentary processes and depositional features. Over the past 3000 yr, the evolution of the MRD has shown a morphological asymmetry indicated by a large down-drift area and a rapid progradation around Cape Camau, ∼ 200 km downstream from the river mouth. This asymmetric feature is consistent with increased wave influence. The strong southwestward coastal current, strengthened by the strong NE monsoon, plays an important role locally in longshore transport of resuspended sediments into the Gulf of Thailand. A late Holocene sediment budget for the MRD has been determined, based on the area and thickness of deltaic sediment. Approximately 80% of Mekong delivered sediment has been trapped within the delta area, which, together with a falling sea-level, resulted in a rapidly prograding MRD over the past 3000 yr.}, number={1-2}, journal={Marine Geology}, publisher={Elsevier BV}, author={Xue, Zuo and Liu, J.

While the retreat rate during 1996–2003 decreased to 1.5 m/y, serious coastal erosion was found around river mouths, such as the Tang, Dai, Yang, Dapu, and Renzaohe Rivers, as well as Qilihai Lagoon, with the maximum of >7.0 m/y. Sediment starvation induced by dams mainly caused this fast coastal retreat. Sediment flux of the Luan River, the dominant fluvial sediment source in the study area, declined to only 9.0% of the levels before the impoundment of two large dams in 1979. Sharply reduced sediment supply disrupted the stability of sediment transport as well as the beaches' self-recovery processes after storm surges. Coastal erosion was further intensified by coastal engineering and tourism activities.}, number={3}, journal={JOURNAL OF COASTAL RESEARCH}, author={Xue, Zuo and Feng, Aiping and Yin, Ping and Xia, Dongxing}, year={2009}, month={May}, pages={723–733} } @article{feng_xue_chi_2008, title={Topographic features around Zhongshan Station, southeast of Prydz Bay}, volume={26}, number={4}, journal={Chinese Journal of Oceanology and Limnology = Zhongguo Hai Yang Hu Zhao Xue Bao}, author={Feng, S.
