Field Activity 2017-324-FA

Identifier 2017-324-FA
Alternate names 17BIM05, 17BIM06, 17BIM07, 17BIM08
Purpose Collect single beam bathymetry and seismic profiles along the Louisiana Chenier Plain coastline from Marsh Island to Sabine Pass, TX.
Location Leg 2: Western Chenier Plain
Summary 683 SBB lines were collected for a total of 1,935 Km of data along the southern LA coast from Rockefeller NWR to Sabine Pass. Four sub-bottom profiles were collected.
Info derived Single beam bathymetry and sub-bottom profiles.
Comments This will be leg 2 of 2 trips to survey the full extent: Sub FANs: 17BIM05 = R/V Sallenger - SBB + chirp 17BIM06 = R/V TwinVee - SBB 17BIM07 = R/V Shark (White = WVR1) - SBB 17BIM08 = R/V Chum (Blue = WVR2) - SBB Entries for this field activity are based on entries from Field Activity 2017-323-FA

26' Parker
Twin Vee (Jabba Jaw)
22-ft Twin Vee This boat has a carrying capacity of up to 1500 pounds and up to 7 people and a shallow draft (9 inches empty). This boat's cat hull design results in a smoother ride in choppy water, at the expense of a slightly deeper draft. This boat is powered by two Yamaha 70hp motors.
