CIS me

It is an underwater portable breathing meter, the name comes fromCoraliyouSITUmeHis glass window(In situ metabolism of corals), pronounced as "kiss-me" to reflect the gentle interaction between the device and coral/substrate.Used to measure the metabolic rate of corals in situ under field conditions.It can also be used to measure coral algae, calcified algae, benthic seaweed, other low-amplitude benthic organisms or substrates, microbial membranes and sediments, sponges, invertebrates, etc.

CISME calculates respiration (R) and photosynthesis (P) from these concentration changes by measuring oxygen flux and ΔpH during short-term incubation to obtain RQS (respiratory rate) and PQS.The sample circuit provides a water sample of total alkalinity (TA) for titration detection to measure calcification (G).The collected water samples can also be used to determine substances that may affect coral metabolism (e.g., acidified seawater).The measurement process can set the flow rate and light level gradient according to the experimental design (obtaining the light response curve).

Design highlights

• Separate relatively small volumes of water samples to facilitate the determination of pH and DO changes in specific time periods

• The water flow velocity keeps the water sample well mixed to minimize stagnation of the boundary layer

• Light control (switch and light level settings)

•Measure photosynthesis and respiration to produce photoresponse curves

• Collect water samples for laboratory analysis

• Additives such as photosynthesis inhibitors can be added for control tests (control group)

instrument design

• Electronic warehouse:It contains host electronic devices, network cards, digital processing and storage devices, etc., with a maximum water tolerance of 70m.

•Hatching head:Includes sensors, pumps, LED light sources and special traction devices for connection to coral/substrate surfaces.

• Instrument operation:CISME is connected to an underwater Android tablet via a network cable and operates through a dedicated Android application system.

• Diving:Lightweight, the equipment and underwater flatbed is 5-7 pounds underwater, making it easy for divers to carry.
