SUBJECT: COVIS (Cabled Observatory Vent Imaging Sonar) Project Annual Report
Report Period Year 1: 1 November 2008 to 31 October 2009
PROJECT TITLE: Collaborative Research (Applied Physics Laboratory-University of Washington and Rutgers University) Acoustic Instrumentation for Imaging and Quantifying Hydrothermal Flow in NEPTUNE Canada Regional Cabled Observatory at Main Endeavour Field, Juan de Fuca Ridge

Collaborative Research Objective: This is a collaborative project between the Applied Physics Lab-University of Washington (Russ Light, PI, APL-UW) supported by NSF grant 0824612 and Rutgers University (Peter Rona, Co-PI) supported by NSF grant 0825088:
1) Develop a sonar system to image flow from seafloor hydrothermal vents (COVIS= Cabled Observatory Vent Imaging Sonar): APL-UW, period 1 November 2008 to summer 2010. RESON sonar system purchased.
2) Test and connect the sonar to the NEPTUNE Canada seafloor cabled observatory: APL-UW, scheduled for summer 2010
3) Initiate imaging of hydrothermal flow at a vent cluster in the Main Endeavour Field on the Juan de Fuca Ridge through the NEPTUNE Canada Oceans-2 DMAS (Data Management and Archiving System) to the user community with near real time quick-look plume images: Rutgers and APL-UW with NEPTUNE Canada, scheduled for summer 2010 (contingent on system preparation). Software under development.

The annual report consists of two sections:
I Applied Physics Laboratory-University of Washington, Russ Light, PI
II. Rutgers University, Peter Rona, Co-PI
