Oyster Update – Virginia Oysters
• Presentation of final results October 2004• Results accepted by Modeling
Subcommittee 2004• We are waiting for approval by review
panel• They are waiting for written report• Report is 75% complete. Expected April 15
2005
Oyster Update - Ariakensis
• Seven of ten proposed scenarios completed December 2004
• Results sent to Mike Fritz (CBP) and Tom O’Connell (DNR) and forwarded to Jon Volstad (VERSAR)
• We can proceed no further without feedback, instructions and inputs for additional runs
Oyster Update - Ariakensis
• Our modeling is on hold pending results of larval transport modeling and population modeling.
• Pick-up in activity in April with finish in autumn 2005.
• A meeting of investigators was discussed but never scheduled.
Model Status
• NAB requested $800,000 from Congress for FY05.
• They received $175,000 of which $160,000 has been transferred to ERDC.
• The $160,000 has been obligated for sediment erosion measures. There is a $10,000 deficit for this work which must be covered.
Model Status
• ERDC was scheduled to receive $185,000 in salaries from NAB, over and above EPA contributions.
• EPA contribution of $216,000 is in the pipeline. This is “off the books” of the cost-share agreement.
• $60,000 intended for menhaden will be diverted to this project. $10,000 will go to field program deficit.
Model Status
• The “core” of this project will be completed. Incorporation of dynamic suspended solids computation into water quality model with emphasis on Potomac and Upper Bay.
• The balance is endangered.
Erosion Rates
• First year field work completed by VIMS, Horn Point, ERDC
• Funding obligated for second year effort by VIMS, Horn Point
• First survey completed March 2005. Next scheduled for June
Light Attenuation
• First year field work completed by Smithsonian
• One survey completed March 2005
• No funding identified for second year’s effort. This is a crisis!
Estuarine Phosphorus Model
• Contracted by MWCOG to LTI and Horn Point.
• Major efforts in 2005 will be field work and literature review.
• No funding identified for ERDC participation
Bank Loads
• MDE has contracted with Jeff Halka to add on to existing work in MD. $50,000
• A simplified approach based on existing info will likely be adapted for Virginia.
pH Alkalinity
• No modeling activity
• MWCOG is exploring options for funding
• Substantial field work conducted in 2004 by Boynton and Cornwell for ICPRB, MWCOG
• Completion of work in this area under this project is endangered
Algal Speciation
• No activity• MWCOG is exploring
potential for funding funding
• Completion of work in this area under this project is endangered
Linkage to WQM
• Additional calibration of HM is halted pending examination of WQM results
• Seven years of hydrodynamics have been produced, 1993-1999. The year 2000 is in preparation.
• We will initially focus on 1993 and 1994. Compare to results on previous grid
Linkage to WQM
• We have received Phase 4.3 WSM loads mapped to new grid
• We have received point-source loads mapped to new grid
• We are in the process of downloading data for 1995-2000
• We are in the process of mapping new grid to current Bay Program segmentation
Linkage to WQM
• We need to find a better way of inputting direct atmospheric loads
• We will have results for July quarterly.
