Phytoplankton are important in global biogeochemistry since they produce the bulk of oxygen on Earth through photosynthesis. They form the base of the marine food web and are primary producers of organic carbon. Some species produce polyether toxins, thus forming harmful algal blooms that can have detrimental effects on local fauna and flora. For these reasons, phytoplankton monitoring in the oceans is critical. It can provide insight to climate change, microbial ecology, biogeochemical cycles and health toxicity of recreational waters. Currently, the oceans are vastly under-sampled and in situ sensors and sensor networks can address this need for sampling. Miniaturised and microfluidic sensors are increasingly being used for phytoplankton monitoring with great promise for future applications. This chapter will provide an overview of traditional methods of phytoplankton analysis, introduce microfluidics, and review the state-of-the art in miniaturised and in situ sensors for algal detection in the oceans read more ...
