Summary of Accomplishment

Ruoying He arrived at WHOI in September 2003 as CICOR 5th postdoctoral scholar. Since then he has been working on two main research projects. The first project is on the Gulf of Maine coastal circulation and harmful algal transport. This work is a part of the MERHAB (Monitoring and Event Response for Harmful Algal Blooms) project led by Dennis McGillicuddy (WHOI AOPE), Don Anderson and Bruce Keafer (WHOI BO).  Ruoying participated in the MERHAB 2003 field survey in the Gulf of Maine where they collected a wonderful set of in-situ measurements of physical and biogeochemical variables. He then implemented and tested an adjoint data assimilative ocean model that assimilates coastal sea levels and currents to hindcast the circulation and material transports. Exciting research findings on the utility of data assimilative ocean model and on mechanisms controlling water exchange and transport processes were presented inseveral scientific meetings and seminars. A paper documenting detailed scientific results is to be submitted for the refereed journal publication. MERHAB 2004 field survey was just completed this summer. With two years in-situ measurements, Ruoying is working on another paper focusing on the inter-annual variability of the Gulf of Maine circulation and transport and will submit it for publication shortly. The second research project Ruoying is involved in is the southeast Atlantic coastal ocean observing system. This is a collaborative study with other investigators from University of Miami (UM), Skidaway Institute of Oceanography (SKIO), University of South Carolina (USC), and University of North Carolina (UNC). Ruoying has played an important role in data analyses of surface wind fields and satellite observations, and real time numerical model nowcast and forecast of coastal circulation. Several journal publications have been produced out of this work. Ruoying will start on September 1st as an assistant scientist in WHOI APOE department. Listed below is a short list of Ruoying’s research activities so far in 2004.
