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 – 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

Plankton Ring Tow Net

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.

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
