“…Future surveys should also cover picocyanobacteria that often remain overlooked due to their very small size but they have been suggested as potential cyanotoxin-producers by numerous studies (Jasser et al, 2017). Also benthic cyanobacteria that have previously been associated with animal poisonings still remain to be fully explored (Quiblier et al, 2013), including investigations of newly observed couplings in ecology of benthic and pelagic communities (Zhang et al, 2015).…”

Toxic cyanobacteria and cyanotoxins in European waters – recent progress achieved through the CYANOCOST Action and challenges for further research

This review aims to summarise the outcomes of some recent European research concerning toxic cyanobacteria and cyanotoxins, with an emphasis on developments within the framework of the CYANOCOST Action: COST Action ES1105, Cyanobacterial Blooms and Toxins in Water Resources: Occurrence, Impacts and Management. Highlights of the Action include phycological and ecological studies, development of advanced techniques for cyanotoxin analysis, elucidation of cyanotoxin modes of action, management techniques to reduce cyanobacterial mass development, and research on methods and practices for cyanotoxin removal during drinking water treatment. The authors have identified a number of gaps in knowledge. Proposed directions for future research on toxic cyanobacteria and cyanotoxins are also discussed.

“…In our study, increased SST and decreased wind speeds were associated with later blooms and mixed layer depth was unrelated to either the timing of the blooms or the annual carbon fixation. Later timing of the spring bloom coupled with increases in precipitation forced by changes in the jet stream (Francis and Vavrus, 2012;Rahmstorf and Coumou, 2011) would lead to spring blooms that continue into the summer in these coastal waters; a situation which occurred in both 2011 (Queirós et al, 2015) and 2012 (Zhang et al, 2015) at station L4. During years with high summer precipitation, there was an increase in both micro-and total primary production (e.g.…”

“…The resulting selection must reduce the number of sites to what is logistically achievable whilst maintaining the delivery of the required scientific outcomes of the project. In the case of the SSB programme, the key importance of the spring bloom on the biogeochemical processes (Zhang et al 2015) dictated the temporal visitation requirements (minimum of 3 visits: pre-, during-and post-bloom); while the variations in sediment type were the key factor considered in terms of spatial requirements (see ' 'Step 3a'' and ''Assessments of confounding variables''). As a minimum, the end-member conditions for a given parameter within the region must be investigated, ideally with information at intermediate sites to 'fill in the gaps'.…”

An approach for the identification of exemplar sites for scaling up targeted field observations of benthic biogeochemistry in heterogeneous environments

Continental shelf sediments are globally important for biogeochemical activity. Quantification of shelf-scale stocks and fluxes of carbon and nutrients requires the extrapolation of observations made at limited points in space and time. The procedure for selecting exemplar sites to form the basis of this upscaling is discussed in relation to a UK-funded research programme investigating biogeochemistry in shelf seas. A three-step selection process is proposed in which (1) a target area representative of UK shelf sediment heterogeneity is selected, (2) the target area is assessed for spatial heterogeneity in sediment and habitat type, bed and water column structure and hydrodynamic forcing, and (3) study sites are selected within this target area encompassing the range of spatial heterogeneity required to address key scientific questions regarding shelf scale biogeochemistry, and minimise confounding variables. This led to the selection of four sites within the Celtic Sea that are significantly different in terms of their sediment, bed structure, and macrofaunal, meiofaunal and microbial community structures and diversity, but have minimal variations in water depth, tidal and wave magnitudes and directions, temperature and salinity. They form the basis of a research cruise programme of observation, sampling and experimentation encompassing the spring bloom cycle. Typical variation in key biogeochemical, sediment, biological and hydrodynamic parameters over a pre to post bloom period are presented, with a discussion of anthropogenic influences in the region. This methodology ensures the best likelihood of site-specific work being useful for up-scaling activities, increasing our understanding of benthic biogeochemistry at the UK-shelf scale.
