Runcie Research paper in Photochemistry and Photobiology, doi: 10.1111/j.1751-1097.2012.01241.x. “Photosynthetic Electron Transport in an Anoxygenic Photosynthetic Bacterium Afifella (Rhodopseudomonas) marina Measured Using PAM Fluorometry.” This paper describes the use of the Blue-RAT in determining values of photosynthetic absorptance, a requirement for the calculation of Electron Transport Rate (ETR). As…

Riddle Research paper in: Global Change Biology, DOI: 10.1111/gcb.12337 The paper discusses applications and analysis of data obtained from autonomous monitoring of photosynthetic capacity and electron transport of selected Antarctic marine macroalgae. Prototype fluorometers and irradiance sensors were used that were…
Read MoreMazzuca et al. 2013, “Establishing research strategies, methodologies and technologies to link genomics and proteomics to seagrass productivity, community metabolism, and ecosystem carbon fluxes”. This paper describes work conducted during a seagrass workshop held in Corsica, France in 2011, as part of the COST Action “Seagrass productivity: from genes to ecosystem management”. Aquation fluorometers were…
Read MoreAquation has recently released a prototype version of its new Submersible Photosynthesis-Respiration System. This system measures the rate of production or consumption of oxygen in a submerged chamber, which provides a good proxy for photosynthesis and respiration rates. The System is only designed to operate two chambers, and is therefore easy to carry, setup and deploy. No…
Read MoreEstimating primary productivity of marine macroalgae in East Antarctica using in situ fluorometry Aquation Director Dr John Runcie and colleague Dr Martin Riddle from the Australian Antarctic Division on the 05Nov2012 published a paper “Runcie, J.W., Riddle, M.J. (2012) “Estimating primary productivity of marine macroalgae in East Antarctica using in situ fluorometry ”. European Journal…
Read MoreOn request from Dr Ritchie we have developed and trialled our new leaf absorptance meter, the “Blue-RAT”, where RAT stands for Reflectance, Absorptance and Transmittance. The Blue-RAT was specifically designed to monitor fluorescence of bacteriochlorophyll which absorbs mostly blue light. White-RAT and Red-RAT versions are also available. see https://aquation.com.au/products/blue-rat-absorptance-meter
Read MoreDr Ray Ritchie has kindly allowed us to post his calculators on our website – see the Tools section. They take the form of spreadsheets, be sure to enable macros after downloading the file. Enjoy! writing a good research paper
Read MoreAquation Director Dr John Runcie and colleague Dr Martin Riddle from the Australian Antarctic Division on the 15July2011 published a paper “Runcie, J.W., Riddle, M.J. (2011) Distinguishing downregulation from other non-photochemical quenching of an Antarctic benthic macroalga using in situ fluorometry”. European Journal of Phycology 46(3). 171-180, doi:10.1080/09670262.2011.584635. The paper describes how automated dark-acclimation and…
