1 Along-Estuary Spatial Variability and Driving Forces Group 3 - Question A (Christine Cass, Alejandra Sanchez, Marianne Corriveau, Hiromu Ishiyama, Genki Terauchi, Dubrava Krievskaya, Anna Malek, Sung Yong Kim)

2 Study Site - Yaquina Bay Cruise 2 - Aug 20, 2013 (Ebb Tide)Cruise 3 - Aug 21, 2013 (Flood Tide)

3 Methods underway flow- through CTDADCP Equipment:

4 Temperature (ºC) EbbFlood Temperature (ºC)

5 Salinity (PSU) EbbFlood

6 Dissolved Oxygen (ml/l) EbbFlood

7 Chlorophyll (mg/m 3 ) EbbFlood

8 Outer Bay Trawl Station: Estuarine Species: - English Sole - Ling cod - Pacific staghorn sculpin - Buffalo sculpin - Penpoint gunnel Oceanic Species: - Sand Dab, - Sand Lance Upper Bay Trawl Station: Estuarine Species: - English Sole - Ling cod - Pacific staghorn sculpin - Buffalo sculpin - Penpoint gunnel Oceanic Species: - NONE! Upper Trophic Level Trends

9 Tides & Currents

10 Freshwater Influence

11 What’s Happening Offshore: Sea Surface Currents NANOOS, High Frequency Radar http://nvs.nanoos.org/HFRadar

12 What’s Happening Offshore? Upwelling signature ●High chl ●Low temp ●High salinity ●Low DO (According to Jane)

13 What’s Happening Offshore? Satellite derived Chl-a 4 days composites Aug 19-22 47.5 N 41 N 127 W123 W ug/L

14 Back to the Question: What is the along-estuary spatial variability in physical, biological and chemical properties and what are the driving forces that create these variations? ●Mouth of Bay: ○ Higher S, Chl ○ Lower T, DO ●Major forces? ○ Tidal ○ Offshore processes (wind-driven upwelling)

15 Thank you!!! Do you have any question s?
