Structure of phytoplankton (Continuous Plankton Recorder and SeaWiFS) and impact of climate in the Northwest Atlantic Shelves
Publisher: Copernicus GmbH
Date: 15-02-2007
Abstract: Abstract. All marine organisms are affected to some extent by the movement and thermal properties of oceanic currents. However phytoplankton, because of its small size is most directly coupled to the physical environment. The intense hydrodynamic activity observed in the Northwest Atlantic Shelves Province makes this region especially intriguing from the point of view of physical-biological interactions. In the present work, remote sensed data of Sea Surface Height (SSH) anomalies, Sea-surface chlorophyll a concentrations (SeaWiFS), and Sea Surface Temperature (SST) are used to complement the Continuous Plankton Recorder (CPR) survey that continuously s led a route between Norfolk (Virginia, USA 39° N, 71° W) and Argentia (Newfoundland 47° N, 54° W) over the period 1995–1998. Over this period, we examined physical structures (i.e. SST and SSH) and climatic forcing associated with space-time phytoplankton structure. Along this route, the phytoplankton structures were mainly impacted by the changes in surface flow along the Scotian Shelf rather than significantly influenced by the mesoscale features of the Gulf Stream. These changes in water mass circulation caused a drop in temperature and salinity along the Scotian Shelf that induced changes in phytoplankton and zooplankton abundance.

Changes in microbial communities during seawater pre-treatment within a desalination plant
Publisher: Inter-Research Science Center
Date: 11-03-2021
DOI: 10.3354/AME01958
Abstract: We analysed prokaryotic and eukaryotic communities across the seawater pre-treatment system of Penneshaw (Kangaroo Island, South Australia) desalination plant, using 16S and 18S rRNA gene sequencing. The richness of operational taxonomic units increased downstream of the pre-treatment system (reverse osmosis feedwater) compared to raw seawater for Archaea , while it decreased for bacteria and protists. Overall, the reverse osmosis feedwater was found to be enriched in ammonia-oxidising bacteria and Archaea compared to raw seawater, and also contained greater proportions of taxa typically observed in aquatic biofilms and/or within other water treatment systems. Although the microbial load was reduced by the pre-treatment system, the increase in proportion of biofilm-associated microbes suggests the presence of active microbial communities within multimedia filters and other parts of the pre-treatment system that might increase biofouling risks.
Can Aggregate-Associated Organisms Influence the Fouling in a SWRO Desalination Plant?
Publisher: MDPI AG
Date: 22-03-2022
DOI: 10.3390/MICROORGANISMS10040682
Abstract: This pilot study investigates the formation of aggregates within a desalination plant, before and after pre-treatment, as well as their potential impact on fouling. The objective is to provide an understanding of the biofouling potential of the feed water within a seawater reverse osmosis (SWRO) desalination plant, due to the limited removal of fouling precursors. The 16S and 18S rRNA was extracted from the water s les, and the aggregates and sequenced. Pre-treatment systems, within the plant remove 5 µm precursors and organisms however, smaller size particles progress through the plant, allowing for the formation of aggregates. These become hot spots for microbes, due to their nutrient gradients, facilitating the formation of niche environments, supporting the proliferation of those organisms. Aggregate-associated organisms are consistent with those identified on fouled SWRO membranes. This study examines, for the first time, the factors supporting the formation of aggregates within a desalination system, as well as their microbial communities and biofouling potential.
A database of chlorophyll a in Australian waters
Publisher: Springer Science and Business Media LLC
Date: 20-02-2018
Abstract: Chlorophyll a is the most commonly used indicator of phytoplankton biomass in the marine environment. It is relatively simple and cost effective to measure when compared to phytoplankton abundance and is thus routinely included in many surveys. Here we collate 173, 333 records of chlorophyll a collected since 1965 from Australian waters gathered from researchers on regular coastal monitoring surveys and ocean voyages into a single repository. This dataset includes the chlorophyll a values as measured from s les analysed using spectrophotometry, fluorometry and high performance liquid chromatography (HPLC). The Australian Chlorophyll a database is freely available through the Australian Ocean Data Network portal ( portal.aodn.org.au/ ). These data can be used in isolation as an index of phytoplankton biomass or in combination with other data to provide insight into water quality, ecosystem state, and relationships with other trophic levels such as zooplankton or fish.

29Si{1H} CP-MAS NMR comparison and ATR-FTIR spectroscopic analysis of the diatoms Chaetoceros muelleri and Thalassiosira pseudonana grown at different salinities
Publisher: Springer Science and Business Media LLC
Date: 31-01-2013
DOI: 10.1007/S00216-013-6746-Z
Abstract: Diatoms are key indicators of marine environmental health. To further understand how diatoms respond to varying degrees of salinity, either due to climate change or brine waste discharge into marine environments, two different diatom species were studied. Thalassiosira pseudonana and Chaetoceros muelleri were cultured at three different salinities namely, 26 practical salinity units (PSU or parts per thousand), 36 PSU (standard salinity for culturing of seawater species) and 46 PSU. Changes in silica and organic content within the cultured diatoms were analysed using solid-state (29)Si{(1)H} cross-polarization-magic angle spinning (CP-MAS) nuclear magnetic resonance (NMR) and attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopies coupled with analysis of variance. (29)Si CP-MAS NMR showed that qualitatively the Q4:Q3 area ratios of C. muelleri, grown away from standard salinities, increased in response to the formation of more condensed (2 ≡SiOH → ≡Si-O-Si≡ + H2O) and/or an increase in closely associated organic matter to the Q4 component of the diatoms. This was not observed for T. pseudonana. However, both species showed the appearance of a new peak centered at 1575-1580 cm(-1) in the ATR-FTIR spectra, designated as the C═N band of nitrogenous purine-type compounds. Further, the C. muelleri species was shown to produce more extracellular polymeric substances at non-standard salinities. On this basis, results suggest that there is a strong relationship between diatom composition and salinity and that C. muelleri is more sensitive to its environment than T. pseudonana.
A database of marine phytoplankton abundance, biomass and species composition in Australian waters
Publisher: Springer Science and Business Media LLC
Date: 25-06-2017
Abstract: There have been many in idual phytoplankton datasets collected across Australia since the mid 1900s, but most are unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate 3,621,847 records of marine phytoplankton species from Australian waters from 1844 to the present. Many of these are small datasets collected for local questions, but combined they provide over 170 years of data on phytoplankton communities in Australian waters. Units and taxonomy have been standardised, obviously erroneous data removed, and all metadata included. We have lodged this dataset with the Australian Ocean Data Network ( portal.aodn.org.au/ ) allowing public access. The Australian Phytoplankton Database will be invaluable for global change studies, as it allows analysis of ecological indicators of climate change and eutrophication (e.g., changes in distribution diatom:dinoflagellate ratios). In addition, the standardised conversion of abundance records to biomass provides modellers with quantifiable data to initialise and validate ecosystem models of lower marine trophic levels.

Anthropogenic shift of planktonic food web structure in a coastal lagoon by freshwater flow regulation
Publisher: Springer Science and Business Media LLC
Date: 22-03-2017
DOI: 10.1038/SREP44441
Abstract: Anthropogenic modification of aquatic systems has erse impacts on food web interactions and ecosystem states. To reverse the adverse effects of modified freshwater flow, adequate management of discharge is required, especially due to higher water requirements and abstractions for human use. Here, we look at the effects of anthropogenically controlled freshwater flow regimes on the planktonic food web of a Ramsar listed coastal lagoon that is under recovery from degradation. Our results show shifts in water quality and plankton community interactions associated to changes in water flow. These shifts in food web interactions represent modifications in habitat complexity and water quality. At high flow, phytoplankton-zooplankton interactions dominate the food web. Conversely, at low flow, bacteria, viruses and nano icoplankton interactions are more dominant, with a substantial switch of the food web towards heterotrophy. This switch can be associated with excess organic matter loading, decomposition of dead organisms, and synergistic and antagonistic interactions. We suggest that a lower variability in flow litude could be beneficial for the long-term sustaining of water quality and food web interactions, while improving the ecosystem health of systems facing similar stresses as the Coorong.

Turbo thin film continuous flow production of biodiesel from fungal biomass
Publisher: Elsevier BV
Date: 02-2019
DOI: 10.1016/J.BIORTECH.2018.11.015
Abstract: Direct biodiesel production from wet fungal biomass may significantly reduce production costs, but there is a lack of fast and cost-effective processing technology. A novel thin film continuous flow process has been applied to study the effects of its operational parameters on fatty acid (FA) extraction and FA to fatty acid methyl ester (FAME) conversion efficiencies. Single factor experiments evaluated the effects of catalyst concentration and water content of biomass, while factorial experimental designs determined the interactions between catalyst concentration and biomass to methanol ratio, flow rate, and rotational speed. Direct transesterification (DT) of wet Mucor plumbeus biomass at ambient temperature and pressure achieved a FA to FAME conversion efficiency of >90% using 3 wt/v % NaOH concentration, if the water content was ≤50% (w/w). In comparison to existing DT methods, this continuous flow processing technology has an estimated 90-94% reduction in energy consumption, showing promise for up-scaling.

Vortex fluidic mediated direct transesterification of wet microalgae biomass to biodiesel
Publisher: Elsevier BV
Date: 10-2018
DOI: 10.1016/J.BIORTECH.2018.06.103
Abstract: A bottleneck in the production of biodiesel from microalgae is the dewatering and lipid extraction process which is the dominant energy penalty and cost. A novel biodiesel production platform based on vortex fluidic device (VFD)-assisted direct transesterification (DT) of wet microalgal biomass of Chloroparva pannonica was developed and evaluated. Fatty acid extraction and fatty acid to FAME conversion efficiencies were used at different parameter settings to evaluate performance of the processing technology in confined and continuous mode. A response surface method based on Box-Behnken experimental design was used to determine the effects of water content, the ratio of biomass to methanol and residence time in the VFD. Average extraction efficiencies were 41% and conversion efficiencies >90% with the processing technology showing a broad tolerance to parameter settings. The findings suggest that VFD-assisted DT is a simple and effective way to produce biodiesel directly from wet microalgae biomass at room temperature.

Microplastics in urban freshwater streams in Adelaide, Australia: A source of plastic pollution in the Gulf St Vincent
Publisher: Elsevier BV
Date: 2023
DOI: 10.1016/J.SCITOTENV.2022.158672
Abstract: The pollution of marine environments from plastic waste is anticipated to increase with current increases in plastic production. Reciprocally, escalating research efforts provide an improved understanding, monitoring, awareness, and mitigation of plastic contamination. Freshwater streams are recognised as one of the main contributors of microplastic pollution in marine environments. Presented here is the first investigation on the abundance of microplastic contamination (>20 μm and <5 mm) in freshwater streams in Adelaide, Australia. Composite s les were obtained from the sub-surface waters of eight freshwater streams (Magazine Wetland, Torrens River, Brownhill Creek, Sturt River, Field River, Christie Creek, Onkaparinga River and Pedler Creek), just before their connection to the Gulf St Vincent. Microplastics were found in all s les and microplastic abundance was 6.4 ± 5.5 particles.L

Approaches for the detection of harmful algal blooms using oligonucleotide interactions
Publisher: Springer Science and Business Media LLC
Date: 09-11-2015
DOI: 10.1007/S00216-014-8193-X
Abstract: Blooms of microscopic algae in our waterways are becoming an increasingly important environmental concern. Many are sources of harmful biotoxins that can lead to death in humans, marine life and birds. Additionally, their biomass can cause damage to ecosystems such as oxygen depletion, displacement of species and habitat alteration. Globally, the number and frequency of harmful algal blooms has increased over the last few decades, and monitoring and detection strategies have become essential for managing these events. This review discusses developments in the use of oligonucleotide-based 'molecular probes' for the selective monitoring of algal cell numbers. Specifically, hybridisation techniques will be a focus.

Spatial and temporal changes of three prey-fish assemblage structure in a hypersaline lagoon: the Coorong, South Australia
Publisher: CSIRO Publishing
Date: 2017
DOI: 10.1071/MF15212
Abstract: Estuaries and coastal lagoons are the dynamic interface among marine, freshwater and terrestrial environments. The Coorong, an Australian wetland, has been ecologically degraded by protracted drought and subsequent low freshwater flow, and transformed into a hyper-saline lagoon system. The Coorong consists of the North and South lagoons and connects to the Southern Ocean through a narrow channel at Murray Estuary. The present study investigated spatiotemporal variation of three primary prey-fish assemblage in the Murray Estuary and Coorong. Spatial change in prey-fish assemblage was detected, but temporal variation was not obvious. Prey-fish assemblage was dominated by greater abundance of small-mouth hardyhead (Atherinosoma microstoma) in the South Lagoon. There was low abundance of sandy sprat (Hyperlophus vittatus) and Tamar goby (Afurcagobius tamarensis) in North Lagoon, and complete absence of both species in South Lagoon. The spatial variation in the distribution of prey-fish assemblage was attributed to elevated salinity gradients (Murray Estuary: 2–30 North Lagoon: 11–75 and South Lagoon: 40–85). The change of prey-fish assemblage is mainly driven by the salinity variation in the Murray Estuary and Coorong. The present study has improved our understanding on the dynamics of small-bodied prey-fish assemblage and key environmental factors regulating fish distribution in the Murray Estuary and Coorong.
