Because phytoplankton respond directly to physical forcings, it is likely that both species composition and timing of blooms will change in response to climate change. While ecosystem models have evolved from parameterization of phytoplankton as total biomass to functional groups and individual species, observational assessment of phytoplankton species on appropriate space and time scales remains a technological challenge.

In shallow waters overlying continental shelves some phytoplankton species, particularly diatoms and dinoflagellates, can form resting stages or cysts that lie dormant in the sediment for months to years. These cysts and resting stages can be either triggered to germinate by exposure to very low levels of light at the end of the winter or can be reintroduced into the euphotic zone by vertical mixing events.

In addition to the need for serious reduction in sensor size, other issues include sensor robustness, depth rating, power consumption, battery life, sensing frequency including conditional sampling, sensing duration of weeks to months, on-board manipulation of water samples, on-board data analysis and compression, data storage and transmission, and ability to be integrated into mobile platforms and moorings. How will the research be conducted?

. High frequency sampling would provide a picture of what really happens during a bloom -- similar to a walk through the garden to see what plant species are there and who grows the fastest; high frequency identification of species would provide an answer to who's blooming and the beginning of the answer to why.
