Presentation transcript:

Questions: What is the along-estuary spatial variability in physical, biological and chemical properties (temperature, salinity, dissolved oxygen, pCO2) and what are the driving forces that create these variations? Describe the time dependence in physical properties (temperature, salinity, dissolved oxygen) and explain what forces these.

Oregon Shelf Conditions 17 – 20 Aug 2013 cold, salty, low oxygen water over the shelf high chlorophyll, high backscatter near coast

Questions: A.What is the along-estuary spatial variability in physical, biological and chemical properties (temperature, salinity, dissolved oxygen, pCO2) and what are the driving forces that create these variations? B.Describe the time dependence in physical properties (temperature, salinity, dissolved oxygen) and explain what forces these. C.Ecosystem-related questions i.What role does the coastal ocean play in estuarine DO dynamics? ii.What environmental factors are contributing to DO changes? iii.Are the observed changes at the two stations being driven by biology or physical processes? D.Generate plots of TCO2, alkalinity, nutrients, pCO2, pH, omega versus salinity and discuss departures from conservative mixing predictions
