Audio Recording Equipment Check

2026-01-28 11:38 UTC gpt-5-2-thinking Open in ChatGPT ↗

Are any of these audio recording equipment:

Valeport Mini CTD, Sontek CastAway CTD (onboard r/v Augusta)

LI-COR LI-1500 Light Meter/logger with LI-190 Quantum sensor, LI-192 Underwater quantum sensor, LI-193 Spherical underwater quantum sensor

RBRsolo PAR logger

YSI Pro ODO Oxygen sensor/logger (onboard r/v Augusta)

YSI ProSolo ODO/CT Oxygen, temperature and salinity sensor/logger, 2 pcs

Onset HOBO U26 oxygen and temperature loggers

Onset HOBO U24 conductivity and temperature loggers

Onset HOBO Pendant temperature loggers

Water samplers, Limnos 2L, 2.8L and Limnos 5L

Plankton nets, mesh sizes 10-200 µm

Sediment samplers: van Veen grab, box corer (small), box corer (large) with 12 acrylic liners, GeMax twincorer, HAPS corer for sandy sediments, Ekman grab, Sediment Limnos, Petit Ponar

Meridata MD-DSS multi-mode sonar system and S-150Pi side-scan sonar with 100 m cable.

No — none of the items you listed are audio recording equipment (like microphones, hydrophones, audio recorders, preamps, or acoustic data loggers).

What they are instead (quick mapping):

Valeport Mini CTD / SonTek CastAway CTD: water column sensors (conductivity–temperature–depth; often salinity too).
LI-COR LI-1500 + LI-190/192/193 sensors: light/PAR (photosynthetically active radiation) measurement, including underwater light.
RBRsolo PAR logger: PAR/light logger.
YSI Pro ODO / ProSolo ODO/CT: dissolved oxygen (optical DO), plus temperature/salinity depending on model.
Onset HOBO U26/U24/Pendant loggers: oxygen/temp; conductivity/temp; temperature loggers.
Water samplers (Limnos bottles): physical water sampling bottles.
Plankton nets: biological sampling.
Sediment samplers (van Veen, box corers, etc.): sediment sampling/coring.
Meridata MD-DSS sonar + S-150Pi side-scan: acoustic sonar imaging (active acoustics), not audio recording of ambient sound.

If you’re specifically looking for underwater audio recording, the keywords you’d expect to see are things like hydrophone, acoustic recorder, passive acoustic monitoring (PAM), sound trap, audio logger, or recorder brands/models (e.g., SoundTrap, icListen, etc.).
