Information to be Derived:
Summary of Activity and Data Gathered: 12 April 2010, drive from Falmouth to Delaware, launch boat and test gear; 13 April 2010, collect resistivity (CRP), depth, salinity/temp, and chirp data around perimeter of Indian River Bay, rough weather in PM, end operations early in SE corner of bay; 14 April 2010, collect data on long E-W lines, equipment problems in AM, Holly Michael and students visit at marina around mid-day, PM resume CRP and salinity/temp/bathy data collection on E-W and some N-S lines, chirp system not operating; 15 April 2010, collect more data along N-S zigzag lines (no chirp), also E-W lines in shallow, SE corner of bay, and set of ~12 closely-spaced lines in a dense box off Holts Landing State Park, load boat on trailer at marina and stow equipment at end of day; 16 April 2010, travel day back to Falmouth from Delaware.

Notes: Data quality problems with bathymetry and salinity/temperature on 13 April PM and 14 April AM associated with placement of instruments too close to bow and chirp towfish; moved astern on 15 April; CRP processed with available and interpolated data for bathymetry and salinity/temperature on 13-14 April; tide stage data downloaded from USGS gauges at Indian River Inlet (Coast Guard Station) and Oak Orchard gauge (#01484595) upstream in Indian River.
