“…Eddy covariance (EC) systems have been recently adapted to aquatic systems including seagrass habitats (Hume et al, 2011). In addition to EC, non-dispersive infrared (NDIR) spectrometry holds promise as an instrument that measures CO 2 between air and sea, as well as within a submerged habitat (Fietzek et al, 2011a). While NDIR spectrometry has not been applied to ecosystem metabolism in seagrass meadows, it does account for changes in pH, which resolves issues with using CO 2 in NEP estimates in the past (Beer et al, 2001;Duarte et al, 2010;Fietzek et al, 2011a).…”

EC and NDIR spectrometry will be valuable tools for future C flux measurements in the near future, however, the use in seagrass habitats world-wide are partially limited due to their technical complexities and expenses from purchase and maintenance, particularly for research in developing countries and institutes with limited resources.…”

“…The HydroC CO 2 sensor is a newly developed device that has recently become available for diverse marine research applications (Fietzek et al 2011). Hence, this work provides some of the first field data acquired with this sensor, being deployed on a demanding platform.…”

“…One of the first small-sized in situ sensors is the HydroC sensor (CONTROS GmbH, Kiel, Germany), which can be deployed at pressures up to 6000 dbar. Power consumption and response time of the instrument as well as size and design of its housing enable this sensor to be deployed on autonomous platforms with limited space and energy availability, such as moorings, floating buoys, or profiling floats (Fietzek et al 2011).…”

“…pH, [7,8] oxygen, [9,10] pCO 2 [11,12]and nitrate [13][14][15][16]) many cannot be measured with sufficient accuracy. As a result many in situ analysers are based around a flow system which can draw a sample from the environment, chemically treat it (typically by adding one or more reagents to produce an optical response proportional to the concentration of the analyte), measure the response and then expel the waste.…”
