One of the parameters we have been asked about most regularly is pH.  We are now delighted to announce that the ANB Sensors S-1000 pH sensor is available as a payload for the ecoSUBm5 AUV, it can be combined with a range of payloads including Conductivity, Temperature, Chlorophyll-a, Turbidity and Dissolved Oxygen to offer an excellent Science class set up for our users.

The S-1000 pH sensor is a high accuracy sensor with initial accuracy of +/- 0.05 pH and is calibration free.  It samples once every 23 seconds whilst on mission and can provide a useful tool in measuring ocean acidification.  Software integration and mechanical design are complete and we look forward to providing this to many ecoSUB users in the future.

Unfortunately we don't have any photos of this configuration yet, but below is a rendered image of an ecoSUBm5 with the flow tube and exhaust visible for the S-1000 pH sensor, along with a Sea-Bird Scientific three channel Chl/CDOM/BB sensor, Valeport CT sensor, Water Linked DVL and nano-modem.

Iain, Alex and Ayana finally got the chance to get out on the water this month, after what seems like a long time! We spent the day out on the Plymouth Quest helping James Fishwick and colleagues at PML capture some footage of their new ecoSUB AUVs for the Marine Tech Expo event.  If you missed the Marine Tech Expo, catch up with it here
