AD5197-S3 and AD5197-S5 pooled with slurp hose. Slurp yellow 3 and slurp black 5 (both small mesh) were paired, collected at the same orange mat within two minutes of each other; other slurp canisters were not used but the slurp hose contained a good deal of mud which yielded animals. Details not in Sealog; pulled from ASNAPS based on timestamps in Victoria Orphan's notes; S3 and S5 coordinates were identical within 5 decimal places. Field notes: Large with white microbial mat on top and pinkish orange potential anme mat on bottom. Pilot: Rick Sanger. Cruise: AT50-12. Details from cruise master sample log.
