With a break in the rain, and mid-level tide, we took a quick run into the marsh today:
S6: shot boom angles (but the CSAT angles were not correct)
S7: shot boom angles (same issue with CSAT)
S15: shot boom angles (same issue)
collected soil core (horrendous! corer was rusted, roots tenacious, gnats all over)
checked out S1's old Qsoil wisard board and probe. Definitively isolated problem to EC-5 probe. Red wisard board is okay.
S8: shot boom angles (same issue)
Made it out under the bridge with 4cm to spare.
