1. Progress Report July 2012 I. Coupled Physical-Biological modeling in SABGOM (SABGOM-BIO, carbon component); II. Coupled Sediment Transport Modeling in Bohai Sea, Yellow Sea, and East China Sea, (BYESED)

2. SABGOM BIO Simulated pCO2 against observation from UGA team Jan 08 2005, n=257, r=0.56

3. SABGOM BIO Simulated pCO2 against observation from UGA team Jan 14 2005, n=8560, r=0.41

4. SABGOM BIO Simulated pCO2 against observation from UGA team Aug 05 2005, n=10180, r=0.23

5. SABGOM BIO Simulated pCO2 against observation from UGA team Oct 17 2005, n=1006, r=0.05

6. SABGOM BIO Simulated pCO2 against observation from UGA team Dec 20 2005, n=1019, r=0.73

7. Problems and Possible Fix Simulated pCO2 is generally higher than observations; Simulated pCO2 is in better agreement with observations during winter (Dec, Jan) than other seasons (Aug, Oct); Possible solutions CPP: conservative alkalinity River Input: turn on/off DIC alkalinity inputs Atmospheric CO2 concentration

8. BYESED Coupled wave-ocean-sediment transport modeling (COAWST) ~50 year hindcast (1958-2006) Realistic forcings (atmospheric, ocean, & river input)

9. Results by the end of 1965 (8 yrs) Yellow River Sediments

10. Results by the end of 1965 (8 yrs) Yangtze Sediments

11. Model stops after 8 yrs simulation (1958-1966 or 1966-1974); Solution- memory issue?- Reduce history file output variables; Other difficulties: 1.5T external disk for omglnx6 and omglnx9 signaled on/off frequently Problems and Possible Fix

12. July-16 Progress Report BYESED (East China Sea sediment transport) 1)Try to run COAWST on RENCI, failed– COAWST support NETCDF 3.X; RENCI only have 4.X; 2)Try to run uncoupled (SWAN/ROMS independently)— Results are different from coupled even no wave- current interaction is activated– SWAN read UV/Zeta from ROMS from time to time 3) Try to run coupled case, increase SWAN step (10min – 20 min) and reduce SWAN-ROMS coummunication (4-hourly to daily): 64 processors on He2, will take < 10 days for an experiment (in-process)

13. Plan for next week and Problems Finish one BYESED experiment Look into SABGOM_BIO application if processors are available (compare in-situ T/S observation) Problems: external disk lost connection even touch/cp every 0.5 hours

14. Progress Report July 23rd What I have done BYESED application: 1.increase SWAN-ROMS communication interval to 1 day, SWAN timesteps to 20 mins; 2.Using COAWST v587, model stop again around year 1977; 3. Using COAWST v411, model stop around year 1972 because of disk space on share2 SABGOM_NF system 1. generate particle release webpage at http://omglnx9.meas.ncsu.edu/zxue/SABGOM/track.html

15. Progress Report July 23rd What to do in this week Continuous look into BYESED application, try to using restart option once model stops; Working on SABGOM_BIO if time permits;
