SPECIFICATION SHEET

Remote Accesses and Phytoplankton Samplers NOAA requires RAS and PPS samplers for use at the new long-term monitoring stations in the Bering and Chukchi seas at stations M8 and C12.

The oxygen RAS samplers will acquire water samples while attached to long term moorings.

Specifications:

Must be to take up to 48 preprogramed water samples into 500 ml tedlar bags.

Must be able to be deployed for a duration of 1 year, sampling throughout the full year.

One Sampler must be able to add fixative to the bag of sample water for preservation until recovery.

The second sampler must be able to add chemicals to the samples at various times.

Sampling must be programmable to sample at preset times.

Must be able to operate in temperatures down to -5 C and depths to 300 m.

Individual samples must be isolated to avoid cross contamination.

Must be able to inject fixative without cross contamination with other samples.

RAS samplers mounted in mooring ready frame desired.

The PPS sampler will acquire plankton samples while attached to long term moorings.

Specifications:

Must be able to take 24 preprogrammed particulate samples on filters.

Must be able to be deployed for a duration of 1 year, sampling throughout the full year.

Must be able to add fixative to the filtered sample for preservation until recovery.

Sampling must be programmable to sample at preset times.

Must be able to operate in temperatures down to -5 C and depths to 300 m.

Individual samples must be isolated to avoid cross contamination.

Must be able to inject fixative into filter holder without cross contamination to other samples

PPS sampler mounted in mooring ready frame with filters desired.
