Charlie Bishop Susanne Brandstatter Ashley Robar P6314 - Field Oceanography Charlie Bishop Susanne Brandstatter Ashley Robar

Details of Study Ship: Anne S. Pierce Duration of Cruise: 1.5 days (Oct. 7th – Oct. 8th)

Study Site Conception Bay 5 fixed stations 2 ADCP transects Open Bay (Oct. 7th) Tickle (Oct. 8th) 5 fixed stations 2 ADCP transects Sonar Survey

Purpose of Project 3 aspects of oceanography in Conception Bay Physical Geological Biological Question: How do these 3 areas interconnect within Conception Bay?

Equipment and Example A= Chaetognath, B= Copepod -1, C= Copepod -2, D= Cladoceran, E= Echinoderm Larvae, F= Gastropod Larvae, G= Larvacean, H= Mysid, I= Shrimp Larvae, J= Pteropod, K= Starfish Larvae. Plankton Ring Tow Net

Equipment and Example Bottom Grab Sampler

Equipment and Example Biosonics Echo-Sounder No data beyond 15 m. This is the default setting, we didn’t adjust it. Also, zooplankton plumes... No fish (not big enough). Biosonics Echo-Sounder

Equipment and Example Secchi Depth Secchi Disk

Equipment and Example Plot CTD data bigger. CTD

Equipment and Example Tides Strong Winds??? Moored Thermistor and ADCP Look at wind data – compare (wind speed and direction). Moored Thermistor and ADCP

Equipment and Example Towed ADCP

Equipment and Example Glider

Equipment and Example Sub-Bottom Sonar

Equipment and Example Side-Scan Sonar Perhaps the overview shot, then zoom in. Side-Scan Sonar

Equipment and Example Multibeam Sonar

Projected Data Analysis Physical Moored ADCP, Moored vs. Towed ADCP, thermistor, CTD, Biosonics  filtering Geological Side-scan, Multi-beam, Sub-bottom sonar  filtering Biological Statistical Analysis among sites, Species Abundance/Dominance, Comparison with Biosonics
