“…Similar relationships have been observed in other Florida estuaries (Robichaux et al 1998, Phlips et al 2011, 2012, as well as estuaries in other regions of the world (Lam & Ho 1989, Voltolina 1993. The specific role of nitrogen enrichment in enhancing the potential for A. sanguinea blooms has been highlighted in several studies (García-Hernández et al 2005, Rothenberger 2007, Kudela et al 2008. The importance of periodic nutrient limitation of phytoplankton production has been demonstrated in many coastal ecosystems in Florida, such as the Indian River Lagoon (Phlips et al 2002), Suwannee River (Bledsoe & Phlips 2000) and the St. Lucie estuary (Phlips et al 2012).…”

Abstract:Akashiwo sanguinea is a cosmopolitan dinoflagellate that has been observed to form major blooms in coastal ecosystems around the world. A. sanguinea plays a major role in the ecology of many marine environments, including coastal ecosystems with variable salinities, where its euryhaline character makes it competitive. The study involved monthly water sampling and measurement of physical-chemical parameters at four sites from the upper reaches of the Caloosahatchee Estuary to San Carlos Bay bordering the Gulf of Mexico. Major A. sanguinea blooms were observed in the Caloosahatchee estuary, with biovolume up to 30.5 10 6 μm 3 mL 1 , equivalent to 740 cells mL 1 , in the upper estuary. The latter regions of the estuary also had the greatest range of salinity and the highest total nitrogen and total phosphorus concentrations. The dynamics of blooms are discussed within the context of spatial and temporal patterns of salinity, temperature and nutrient concentrations, as they relate to hydrologic and climatic conditions.

“…In Monterey Bay, blooming of toxigenic diatoms has been directly linked to wind-driven upwelling [11], and blooming of a dinoflagellate species that can cause massive mortality of seabirds [12] has been linked to canyon upwelling [9]. Additionally, anthropogenic nutrient sources regulate toxicity of HAB diatoms [13] as well as bloom dynamics of a dinoflagellate species linked to seabird mortality [14].…”

Application of the Hyperspectral Imager for the Coastal Ocean to Phytoplankton Ecology Studies in Monterey Bay, CA, USA

As a demonstrator for technologies for the next generation of ocean color sensors, the Hyperspectral Imager for the Coastal Ocean (HICO) provides enhanced spatial and spectral resolution that is required to understand optically complex aquatic environments. In this study we apply HICO, along with satellite remote sensing and in situ observations, to studies of phytoplankton ecology in a dynamic coastal upwelling environment-Monterey Bay, CA, USA. From a spring 2011 study, we examine HICO-detected spatial patterns in phytoplankton optical properties along an environmental gradient defined by upwelling flow patterns and along a temporal gradient of upwelling intensification. From a fall 2011 study, we use HICO's enhanced spatial and spectral resolution to distinguish a small-scale "red tide" bloom, and we examine bloom expansion and its supporting processes using other remote sensing and in situ data. From a spectacular HICO image of the Monterey Bay region acquired during fall of 2012, we present a suite of algorithm results for characterization of phytoplankton, and we examine the strengths, limitations, and distinctions of each algorithm in the context of the enhanced spatial and spectral resolution.

“…Similarly, upwelling regions off the coast of Portugal contain high numbers of Pseudonitzschia cells, which are used as upwelling indicators during spring and summer (Moita, 2001;Loureiro et al, 2005). Riverine inputs have stimulated toxic Pseudo-nitzschia blooms in many regions and are characterized by lower salinities and higher temperatures than upwelling zones (Smith et al, 1990;Horner and Postel, 1993;Dortch et al, 1997;Scholin et al, 2000;Spatharis et al, 2007;Kudela et al, 2008). A distinction between nutrients in upwelling and river plumes is that riverine inputs are likely the result of anthropogenic nutrient loading, including agricultural runoff and sewage.…”
