Xutong reported on the results of processing GPS data in Lake Erie. He found that two points are showing a significant difference from the results that were processed three years ago. Results from a detailed comparison will be available soon. 

Chung-yen worked on the SRTM data datum conversion and checked the altimetry data records in Tampa Bay. Only a few data spots inside the Bay have records. He will work on these spots by combining gauge station observations. 

Professor Bedford gave an update on Tampa Bay modeling. In terms of Tampa Bay water surface modeling, he mentioned that there are several factors that affect the water surface level inside the bay, including warm water going from the Atlantic Ocean into the Gulf of Mexico through Key West, the pumping mode at the entrance of Tampa Bay, and the affects of hurricanes. We are not able to capture all of these factors. He suggested using the gauge station outside the Bay (Clearwater Beach Station) to set up a boundary condition for Tampa Bay modeling. He made the assumption that the water level observed at the gauge station (Clearwater Beach) would propagate into the inside of the Bay. We need to determine the specific time delay for corresponding water-level change at stations inside the Bay. A comparison/correlation between gauge station observations outside and inside the Bay should be done first to prove this assumption. If the assumption is correct, Professor Bedford will apply the Princeton Ocean Model (POM) to the Tampa Bay water-level modeling. Alok will help Professor Bedford with model grid generation and related work for modeling Tampa Bay.
