As plastic production increases, so to do the threats from pollution. Microplastics (defined as plastics <5mm) are a subset of marine debris about which we know less than larger items, though they potentially ubiquitous in environment. To quantify distribution and change microplastic densities through time, sampled sediment cores an estuary Tasmania, Australia. We hypothesized that type, abundance microplastics observed would be associated with increasing production, coastal population...
Macroecological relationships provide insights into rules that govern ecological systems. Bergmann's rule posits members of the same clade are larger at colder temperatures. Whether temperature drives this relationship is debated because several other potential drivers covary with temperature. We conducted a near‐global comparative analysis on marine copepods (97 830 samples, 388 taxa) to test rule, considering drivers. Supporting we found better predicted size than did latitude or oxygen,...
Abstract. Southern Ocean waters are projected to undergo profound changes in their physical and chemical properties the coming decades. Coccolithophore blooms thought account for a major fraction of global marine calcium carbonate (CaCO3) production export deep sea. Therefore, composition abundance coccolithophore populations likely alter carbon cycle, with feedbacks rate climate change. However, contribution coccolithophores CaCO3 is uncertain, particularly circumpolar subantarctic zone...

Abstract Although the supply of iron generally limits phytoplankton productivity in Southern Ocean, substantial seasonal blooms are observed over and downstream Kerguelen plateau Indian sector Ocean. Surprisingly, oceanic blooms, those associated with deeper southern last much longer (~3 months) than northern bloom (~1‐month plateau). In this study, mechanisms around were investigated, obtaining profiles dissolved (<0.2 μm, dFe) to 2,000‐m deep at 25 stations during austral summer 2016....
Abstract There have been many individual phytoplankton datasets collected across Australia since the mid 1900s, but most are unavailable to research community. We searched archives, contacted researchers, and scanned primary grey literature collate 3,621,847 records of marine species from Australian waters 1844 present. Many these small for local questions, combined they provide over 170 years data on communities in waters. Units taxonomy standardised, obviously erroneous removed, all...
Abstract Ocean acidification is expected to have detrimental consequences for the most abundant calcifying phytoplankton species Emiliania huxleyi . However, this assumption mainly based on laboratory manipulations that are unable reproduce complexity of natural ecosystems. Here, E. coccolith assemblages collected over a year by an autonomous water sampler and sediment traps in Subantarctic Zone were analysed. The combination taxonomic morphometric analyses together with situ measurements...
The Integrated Marine Observing System National Reference Station network provides unprecedented open access to species-level phytoplankton and zooplankton data for researchers, managers policy makers interested in resource condition, detecting understanding the magnitude time-scales of change our marine environment. We describe how spatial temporal plankton collected from seven reference stations located around Australian coastline, a summary associated physical chemical parameters measured...
Understanding impacts of global warming on phytoplankton – the foundation marine ecosystems is critical to predicting changes in future biodiversity, ocean productivity, and ultimately fisheries production. Using community abundance environmental data that span ~90 years (1931-2019) from a long-term Pacific Ocean coastal station off Sydney, Australia, we examined response using Community Temperature Index, an index preferred temperature community. With ~1.8℃ at site since 1931, found...
The 100-year operation of the Mount Lyell Mining and Railway Company Limited’s copper mine in Queenstown, Australia, has resulted deposition over 100 million cubic metres tailings, smelter slag topsoil into King River Macquarie Harbour. Apreliminary risk assessment, together with chemical measurements dissolved copper, ASV-labile complexing capacity resin-adsorbed suggested that mid-salinity harbour waters was potentially bioavailable. However, toxicity tests based on inhibition microalgal...
Abstract Chlorophyll a is the most commonly used indicator of phytoplankton biomass in marine environment. It relatively simple and cost effective to measure when compared abundance thus routinely included many surveys. Here we collate 173, 333 records chlorophyll collected since 1965 from Australian waters gathered researchers on regular coastal monitoring surveys ocean voyages into single repository. This dataset includes values as measured samples analysed using spectrophotometry,...
The Southern Ocean is warming faster than the average global ocean and particularly vulnerable to acidification due its low temperatures moderate alkalinity. Coccolithophores are most productive calcifying phytoplankton an important component of ecosystems. Laboratory observations on abundant coccolithophore, Emiliania huxleyi, suggest that this species susceptible variations in seawater carbonate chemistry, with consequent impacts carbon cycle. Whether anthropogenic environmental change...
Marine ecosystems regulate atmospheric carbon dioxide levels by transporting and storing photosynthetically fixed in the ocean's interior. In particular, subantarctic polar frontal zone of Southern Ocean is a significant region for physically-driven uptake due to mode water formation, although it under-studied concerning biologically-mediated uptake. Regional differences iron concentrations lead variable export from base euphotic zone. Contrary our understanding globally, where high...
This work describes the development of an instrument for measuring free and total copper in seawater by continuous flow analysis (CFA) with Orion copper(II) ion selective electrode (CuISE). Sample times are reduced considerably using extrapolation technique based on fitting empirical mathematical expression to time-response curve enabling a prediction final equilibrium potential. CuISE measurements samples containing nanomolar levels can be very time consuming, this predictive approach...
