Abstract:
There appears to be an overwhelming urge in the study of earth sciences currently to discover the “cosmic generality.” Certainly, no observational and descriptive aspects of the study of earth history can be concluded until one has placed the observations into a broader context. On the other hand, there are not very many “cosmic generalities” and few lasting generalizations have been developed before the basic data have been gathered. When generalizations do precede observations, the former fall into the category of testable hypotheses or speculations, depending upon the overall plausibility of the ideas and the generosity of the reader.

Abstract:
Invasive species can have severe impacts on ecosystems, economies, and human health. Though the economic impacts of invasions provide important foundations for management and policy, up-to-date syntheses of these impacts are lacking. To produce the most comprehensive estimate of invasive species costs within North America (including the Greater Antilles) to date, we synthesized economic impact data from the recently published InvaCost database. Here, we report that invasions have cost the North American economy at least US$ 1.26 trillion between 1960 and 2017. Economic costs have climbed over recent decades, averaging US$ 2 billion per year in the early 1960s to over US$ 26 billion per year in the 2010s. Of the countries within North America, the United States (US) had the highest recorded costs, even after controlling for research effort within each country ($5.81 billion per cost source in the US). Of the taxa and habitats that could be classified in our database, invasive vertebrates were associated with the greatest costs, with terrestrial habitats incurring the highest monetary impacts. In particular, invasive species cumulatively (from 1960–2017) cost the agriculture and forestry sectors US$ 527.07 billion and US$ 34.93 billion, respectively. Reporting issues (e.g., data quality or taxonomic granularity) prevented us from synthesizing data from all available studies. Furthermore, very few of the known invasive species in North America had reported economic costs. Therefore, while the costs to the North American economy are massive, our US$ 1.26 trillion estimate is likely very conservative. Accordingly, expanded and more rigorous economic cost reports are necessary to provide more comprehensive invasion impact estimates, and then support data-based management decisions and actions towards species invasions.

Abstract:
Introduction: My work with the Middlesex University Urban Pollution Research Centre has been conducted in the following areas: 1 Biological Monitoring of Urban Waters (Publications 1, 3, 5, 6, 25) Conventional biological methods and hydrobiological indices used for assessing water quality have been tested in urban streams and rivers and their limitations exposed. The impact of river engineering and physical disturbance on the substrate during storm events has been shown to influence significantly the index scores in addition to pollution impacts. The recommendation to compare biological with physico-chemical assessment of water quality has also been adopted by the National Rivers Authority. A model to predict the community diversity index score for urban stream macro invertebrate biota from recorded physico-chemical parameters was satisfactory for fairly clean waters and for moderate levels of pollution but not for serious levels of pollution (1). Reference streams and ponds in Trent Country Park on the fringe of North London were used for comparison with studies of the biota of urban waters (3,5). A system of river classification using a hydrobiological score system was proposed to complement the existing National Water Council system which was essentially based on chemical criteria (6). A study of the use of indicator organisms to monitor the impact of localised discharges of urban surface runoff and storm sewer overflows was commissioned by the Water Research Centre, the results of which are reported in paper no. 14. A review of the use of macroinvertebrates and plants as bioindicators in urban aquatic systems is included in publication 25. 2 Aquatic Ecotoxicology (Publications 3, 4, 5, 6, 7, 9, 11, 12, 14, 21, 24, 26, 28, 32, 34) 2.1 Heavy Metals Innovative methods have been developed for assessing heavy metal bioaccumulation in selected macro invertebrate species in urban waters. Traditionally, toxicity tests have been conducted in controlled laboratory conditions which do not simulate the natural environment. The use of caged macro invertebrates secured to the substrate in rivers, enables a more realistic determination of bioaccumulation and mortality rates to be made. The impact of storm events and chronic exposure to contaminated water and sediment has been investigated. At a time when new ecotoxicological tests are being introduced to the UK and the EC, the research has considerable potential application as a test for heavy metal impacts and the determination of environmental standards in freshwater. (The research has been sponsored by the Water Research Centre). VI Tissue concentrations of lead, cadmium, copper and zinc in selected macroinvertebrates collected from semi-rural and urban streams and ponds are reported in papers 3, 4 and 5. The relationship between urbanisation and macro invertebrate tissue, sediment and water metal concentrations and their spatial trends along the Salmon's Brook in North London is discussed in publication 6 and compared with the results from the A veiro Lagoon and its feeding rivers in North Portugal in paper 7. Tissue metal bioaccumulation in popUlations of caged Gammarus pUlex, Asellus aquaticus and Lymnea peregra in relation to ambient sediment and water metal concentrations, metal species bioavailability and organism feeding behaviour are discussed in publication 9. A comparison of mortality and metal uptake in aquatic macroinvertebrate species in field studies and laboratory experiments and a recommendation to reduce the length and lethal limit of the traditional 96 hour LC50 test is made in papers 11, 21, 24 and 32. The impact of storm sewer overflows from a sewage treatment works on caged macro invertebrates exposed to the discharges and to the receiving waters immediately downstream is reported in publications 12, 14 and 24. Principal component analysis was used to determine combinations of caged Aselius aquaticus tissue, sediment and water metal concentrations, precipitation volumes and antecedent dry periods which explained much of the variation in organism mortality and weight (28, 34). 2.2 Hydrocarbons (Publications 15 - 20, 29) Caged macro invertebrate species have also been used to determine hydrocarbon bioaccumulation in an urban stream and the Welsh Harp reservoir, a site of special scientific interest. Sediment and water hydrocarbon concentrations and macro invertebrate community diversity have been monitored along the stream and in the reservoir to investigate the impact of an oil boom. The development of biological and chemical techniques in this unique study of an urban freshwater wetland has led to considerable interest and further publications are planned. (The research has been sponsored by English Nature, formerly the Nature Conservancy Council). Publications 15 and 16 describe a baseline study of the ecotoxicological impacts resulting from oil pollution on the Welsh Harp and one of its receiving streams. Sediment and water concentrations of alkanes and P AHs and the tissue concentrations and temporal and spatial trends in selected caged macro invertebrates and fish are reported in publications 17, 18 and 19. The bioaccumulation of hydrocarbons by macro invertebrate species in laboratory tests and the corresponding mortality rates and their comparison with the results of field studies and controlling factors are discussed in publication 20. The results of the study are summarised in paper 29. vii 3 Aquatic Macrophyte Pollution Control (Publications 10, 13, 22, 23, 27, 31, 33, 35) Heavy metal uptake by the reedmace Typha latifolia, an aquatic plant species, has been investigated in urban wetlands and in greenhouse based studies. The research has shown a high level of tolerance by Typha to heavy metals and its biofiltration ability and creation of a sediment metal sink. It has led to the introduction of Typha in pioneering designs of constructed wetlands for highway runoff treatment in the UK. (The research is ongoing and is receiving sponsorship from industry and PCFC). A comparison of the water pollution control performance of Typha latifolia in the UK and Eicchomia crassipes in China is discussed in publication 10. Further details of the study of metal uptake in Typha latifolia and its associated sediment in the Welsh Harp and two ornamental ponds and a comparison with the results of a greenhouse based metal dosing experiment are given in papers 13 and 27 and summarised in 23 and 31. An analysis of the metal and hydrocarbon uptake and biofiltration ability of different species of aquatic macrophyte in an experimental pond receiving runoff from a car park in Washington State, USA is described in report 33.

Abstract:
The consequences of predation have become a central focus of marine ecological research. Numerous studies have emphasized the importance of apex predators in structuring assemblages at various organisational levels and in determining how ecosystems function. However, less appreciated currently is the fact that predators display multiple foraging behaviours, thereby allowing them to overcome problems associated with unpredictability of food resources in space and time. The primary goal of this dissertation is to contribute to growing understanding of the ecological causes and consequences of foraging plasticity displayed by Greater Flamingo Phoenicopterus ruber roseus in intertidal sandflat ecosystems in Langebaan Lagoon, South Africa. P. roseus feeds by either (1) creating pits, which involves flamingos stirring up deep sediments with their feet or (2) creating channels, in which their inverted bills are swept from side-to-side on the sediment surface. The first objective of the study was to quantify the ecological drivers of decisions made by flamingos to feed, and to implement either pit- or channel-foraging strategies. The latter was achieved through RandomForest modelling techniques that identified the prominent ecological drivers from a suite of biotic and abiotic variables. Results indicate that biotic variables, i.e. those associated with flamingo prey assemblages, were key in driving choices made by flamingos to forage and to implement either pit- or channel-foraging strategies. The second aim of this dissertation was to quantify the repercussions of the two different foraging behaviours on benthic assemblages. Comparisons of benthic assemblages in flamingo foraging structures (pits and channels) with adjacent non-foraged sediments (controls) indicated differential effects of both flamingo foraging methods on benthic communities, with channel-foraging eliciting a greater negative impact compared to pit-foraging, for which impacts were negligible. Abundance of macrofauna and surface-dwelling taxa such as micro-algae and the amphipod Urothoe grimaldii were all negatively impacted by channel-foraging. Sizes of channels constructed by flamingos were inversely related to their impacts, with impacts on macrofaunal abundance being greater in smaller channels. Overall, this study has shed light on the differential effects of foraging plasticity on prey assemblages and its importance in enhancing spatio-temporal heterogeneity in intertidal sandflats. The study also emphasizes the need to incorporate foraging plasticity into current thinking and conceptual models of predation in marine soft sediments, in order to appreciate the full spectrum of predation effects on assemblages.

Abstract:
The impacts of biological invasions on native avian diversity have been the subject of many studies in Africa. However, a holistic synthesis of available information from different taxa and their impacts on native birds is lacking. From published information, I analysed the negative and positive effects of biological invaders on native African birds from five taxa: plants, invertebrates, fish, mammals and birds. In order to assess functional gains and losses, native birds were categorized into their functional guilds defined by their primary diet. I limited my scope to mainland Africa at the biome level. ArcView GIS 3.3 software was used to map locational data of impacts within the major biomes. The results indicate that a minimum of 572 native birds are negatively impacted by invasive species from the five taxa. This represents ca 29% of all the bird species in Africa. In contrast, only 191 species of native birds benefited from such invasions. Birds whose diet was primarily insects were disproportionally impacted. The majority of the impacts were caused by invasive plants. At the biome level, the greatest numbers of native birds impacted were in the Montane grassland and shrubland biome. It is predicted that native birds will continue to lose more than they gain from biological invasions in the continent.

Abstract:
Elephant are renowned for their ability to substantially alter vegetation. However, as they need to drink regularly, surface water exerts a strong influence over the distribution and magnitude of elephant impacts on vegetation. This study was conducted in Zambezi National Park, a 560 km2 unfenced protected area in northwest Zimbabwe. It aimed to investigate the impacts of elephant on woody vegetation, particularly in relation to artificial waterholes. Sampling plots were located at different distances from four pumped waterholes in teak (Baikiaea) and Terminalia woodlands, the two main woody vegetation types recognised in the study area. Plots were set at 200, 500, 1000, 2000 and 4000 m from waterholes in the teak woodland. Due to the close proximity of waterholes, a lower maximum distance of 2500 or 3000 m from waterholes had to be used in the Terminalia woodland, but sampling intervals from 200-2000 m were otherwise the same. Assessment of elephant browsing and a series of measurements were performed on trees and shrubs within these plots, with plants assigned to one of three height classes (0.2 - < 1 m; 1 - <3 m and ≥3 m). Elephant dung counts were also conducted in these plots, to provide a measure of elephant occupancy. A clear decline in elephant browsing with distance from waterholes was evident in both the teak and Terminalia woodlands. However, elephant browsing was consistently higher in the latter woodland type. Averaged across all plant height classes, elephant had removed 30-45% of plant canopies in most Terminalia woodland plots. More moderate canopy removal of 10- 30% was found in most teak woodland plots. Plants ≥3 m were particularly highly browsed in the Terminalia woodland, with over 50% of their canopy volume removed in most plots. Elephant browsing impacts were also considered at the species level, which revealed clear differences in browsing levels among species. Some uncommon and highly browsed species were flagged as being potentially vulnerable to disappearance from the area, even in the teak woodland where overall elephant browsing was lower. The effects of elephant browsing on vegetation structure at different distances from artificial waterholes were also investigated. Little change was apparent in the teak woodland, where the only noted impact was a reduction in the density and canopy volume of plants 1 - <3 m tall, limited to within 1 km of waterholes. More pronounced structural impacts were evident in the Terminalia woodland. Substantial declines in the basal area and canopy volume of trees (i.e. plants ≥3 m) occurred closer to waterholes, with widespread conversion of woodland to shrubland evident. Reductions in both tree and shrub canopy volumes closer to waterholes also suggested a reduction in browse availability in the Terminalia woodland. Finally, elephant dung declined with distance to waterholes, confirming that elephant were found in higher densities closer to waterholes. However, dung counts did not reveal different levels of elephant occupancy between the two vegetation types, despite higher browsing in the Terminalia woodland. This finding suggests elephant might be using the teak woodland for purposes other than just browsing, such as for shade. The study thus provided evidence that waterholes have had a significant impact on vegetation in the area, particularly on the favoured Terminalia woodland. Acknowledging the tourism value of retaining waterholes in the area, it is suggested that distances between waterholes should be increased, through only continuing pumping at waterholes with viewing platforms. This could result in a more heterogeneous elephant browsing regime across the highly impacted Terminalia woodland in particular, and lessen further homogenisation of this vegetation type towards a shrubland.

Abstract:
Traditionally, hypoxia has been defined as the situation where DO levels have fallen below 2.0 mg O2 L-1, but increasing evidence suggests that this low level of DO is inadequate to describe the onset of hypoxia impacts for many organisms. Consequently, there is a need for a greater understanding of how ‘moderate’ alterations in DO levels will affect ecosystem processes and functionality, specifically through behavioural and physiological alterations at the organism and community level. This thesis reports on mesocosm experiments which were conducted to examine the effects of moderate ( > 3.0 mg O2 L-1) hypoxia on firstly, a key ecosystem engineer, the brittlestar Amphiura filiformis, and secondly, on the Station L4 infaunal macrobenthic community. Station L4 is a longstanding marine biodiversity and MSFD reference site and forms part of the Western Channel Observatory. At the organism level, short-term (14 d) exposure to moderate hypoxia significantly reduced oxygen uptake rates, oocyte diameter and oocyte development in A. filiformis. However, these physiological affects occurred irrespective of brittlestar population density. Additionally, moderate hypoxia reduced brittlestar activity, in terms of bioturbation behaviour, consequentially having an effect on ammonium and silicate fluxes. These observations were only detected when brittlestar population density was high. It was concluded that denser populations of A. filiformis may therefore exhibit the greatest changes in behaviour and shifts in ecosystem function as competition for resources and oxygen heightens. The benthic community at Station L4, displayed considerable tolerance to medium-term (6 wk.) exposure to moderate hypoxia, in terms of structure, diversity and bioturbatory behaviour, but these results may be different if exposure was longer or more severe. Alterations in nutrient fluxes were detected, but there was little evidence to suggest these changes were due to macrofaunal behavioural alterations. Additionally, results from this study revealed that bringing complex natural communities into the mesocosm caused a substantial loss of individuals and species, mainly due to translocation and disturbance effects. This important insight into the effects of bringing community assemblages into the mesocosm confirms that even with a loss of diversity, the L4 community maintained functionality and was resilient to alterations in DO. This suggests that the L4 benthic community does not depend on any one specific species for the provision of important ecosystem processes, resulting in considerable functional resilience within the L4 system. However, vulnerability to benthic systems may increase if functionality is dominated by species such as A. filiformis. Consequently, moderate hypoxia may not immediately affect benthic communities in terms of structure and diversity, but the physiological effects on individuals, especially to reproductive development, may cause alterations in the quality and quantity of planktonic propagules supplied by benthic species to the pelagic environment. This could affect benthic community diversity and functionality in the long term if repeated hypoxic events occur.

Full text
Abstract:
In 1997, land reclamation works began in the coastal area of Mukim Lekir. Ultimately, an area of 8,094 ha was planned to be reclaimed along Lekir's coastline, but to date; only Phase 1 of the project has been completed. The Phase 1 project of 405 ha, created a man-made island for the location of a 2,100MW, coal-fired power plant; a first of its kind in Malaysia. Although the reclaimed land was only 5 % of the total intended area, its impacts on the livelihoods of the coastal communities, especially fishers, were serious and nearby mangroves were degraded. The effect of this intervention was observed to be long-term, contrary to the claims made by the project proponents. Fishers and other coastal inhabitants incurred monetary losses, which were neglected by the project proponents, who also failed over the issue of compensation. This study attempts to establish evidence that the project caused hardship to coastal population, especially fishers who depended on fishery resources that were found to decline after the commencement of the project. It began by assessing the status of fish stock, analysing its catch-rates trend and comparing them with resource status before the project. A socio-economic survey by face-to-face questionnaires interview was carried out on the population to obtain information on how the project had affected their livelihoods in terms of incomes, job opportunity, fishing activities, pollution, etc. The research design intended to prove that environmental degradation was caused by the project by comparing the status of resources before and after the intervention. On the issue of compensation, losses were valued in monetary terms, so that it was easily understood and appreciated. The purpose of valuing damages was to allow affected persons to claim compensation in monetary terms. This study emphasized losses through mangrove degradation and losses as result of fishery resources declining. In addition, losses incurred by cockle farmers and the government were also gauged. For mangrove degradation, a survey using the Contingent Valuation Method was carried out to estimate people's willingness to pay (WTP) on a hypothetical project aiming to protect the mangroves. The amount they were WTP was the benefit loss of not being able to use the mangroves. Other losses valuation was straightforward since it involved marketable or tangible goods. The standing of fishers and other affected communities claiming compensation in the court of laws was discussed. Fish stock assessment done in 2002 and 2003 in the Lekir waters indicated that the resource showed a declining trend since 1996. Commercial fish declined at a greater rate in sub-area A, which was closer to the impacted area, than in sub-area B; located further away. Subarea A was also found to loose its potential as breeding and nursery grounds, since fewer juveniles and fingerlings were caught compared with the 1996 survey. The decline in the fisheries indicative from the surveys was verified by fishers who complained of reduced catches and incomes. In the socio-economic survey, fishers were found not to benefit from the development since the project did not provide them with employment opportunity or generate other kinds of income-induced opportunity. The degradation ofthe mangroves and the fishery were proven to be caused by the present of the project since the control areas, in the absence of perturbation did not show similar characteristic as the impacted areas. The benefit loss of mangrove use was estimated at RM 81,959/year whereas other society losses were RM 118,333,321 in the six years since the perturbation. If fishers were to claim compensation, they have to prove that their losses were above and over the general public and preferably under the rule of Rylands V Fletcher. Other segments of the society may need government intervention since they were claiming pure economic loss, which is unrecoverable in the Common Laws. This study does not advocate monetary compensation to each affected individual but prefers long-term aid to regenerate rural livelihoods. Economic projects are proposed involving active participation of the community. Further researches are also suggested to improve data collection, developing comprehensive stock assessment and improving EIA procedures.

Full text
Abstract:
As trends in urbanisation continue globally, there is a growing need to understand the impacts of urban development on wildlife. Whilst urban impacts on patterns of diversity and abundance of species have been well-studied, there remains a distinct lack of understanding around the impacts on ecological interactions. Different species have different levels of tolerance to urban disturbance, some species even appear to thrive in urban areas and make use of human-subsidised resources; but the physiological costs and trade-offs faced by urban-dwelling species are poorly understood. Given that their range in South Africa has only recently expanded into the human-dominated landscapes of the Western Cape, the Black Sparrowhawk (Accipiter melanoleucus) provides an excellent opportunity to explore some of these questions. In this study we explored how urbanisation may affect the health of this raptor on the Cape Peninsula, South Africa. If the health of this species is negatively influenced by levels of urbanisation, this might be driven by differences in diet and prey availability across the urban spectrum. Thus, we explored this potential mechanism by examining diet composition and assessing prey abundance within different territories and habitat types. The health of nestling Black Sparrowhawks was evaluated through their immune response (Heterophil/Lymphocyte ratio in white blood cell counts), body condition (based on morphometric measurements) and blood parasite infection (presence and abundance of Haemoproteus and Leucocytozoon). Trends in diet composition along a gradient of urban cover were determined through the analysis of prey remains collected in the immediate nest surroundings and differences in prey abundance were determined through point counts in different habitat types.

Thesis advisor: Hilary Palevsky
The ocean plays a key role in global carbon cycling, taking up CO2 from the atmosphere. A fraction of this CO2 is converted into organic carbon through primary production in the surface ocean and sequestered in the deep ocean through a process known as the biological pump. The ability of the biological pump to sequester carbon away from the atmosphere is influenced by the interaction between the annual cycle of ocean mixed layer depth (MLD), primary production, and ecosystem processes that influence export efficiency. Gravitational sinking of particulate organic carbon (POC) is the largest component of the biological pump and the aspect that is best represented in Earth System Models (ESMs). I use ESM data from CESM2, an ESM participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6), to investigate how a high-emissions climate change scenario will impact POC flux globally and regionally over the 21st century. The model simulates a 4.4% decrease in global POC flux at the 100 m depth horizon, from 7.12 Pg C/yr in the short-term (2014-2034) to 6.81 Pg C/yr in the long-term (2079-2099), indicating that the biological pump will become less efficient overall at sequestering carbon. However, the extent of change varies across the globe, including the largest POC flux declines in the North Atlantic, where the maximum annual MLD is projected to shoal immensely. In the future, a multi-model comparison across ESMs will allow for further analysis on the variability of these changes to the biological pump

Abstract:
In this report, we describe how aspects of existing freshwater mussel indices of biological integrity can be modified to fit within the planning paradigm established for developing and certifying ecological models for U.S. Army Corps of Engineers’ planning purposes. Herein, we present examples of using freshwater mussels for biological monitoring, how to calculate their associated IBIs specific to their region of origin and their potential use in ecosystem restoration planning. Additionally, we present general conceptual models that may be used in ecological model development and environmental benefits analysis for projects that focus on freshwater mussel habitat restoration.

Full text
Abstract:
Recognition and management of anthropogenic environmental impacts as ‘biosecurity’ is a relatively new concept to our society. Although biosecurity risks are based on biological impacts, biosecurity management is truly interdisciplinary-transdisciplinary since the definition and interpretation of risk and adverse effects are socially constructed, and the outcomes and management of the risks can have significant social and economic impacts. The New Zealand biosecurity strategy is very clear that the responsibilities for environmental risk management lie with society as a whole. The authors explore how disciplines other than biology may contribute to the understanding of biosecurity risks, their management and mitigation. This paper outlines the interdisciplinary-transdisciplinary nature of biosecurity, with an emphasis on the social and economic elements.

Abstract:
The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence. Recent decades have been warmer than at any time in roughly 120,000 years. Most of this warming can be attributed to anthropogenic activity, primarily burning fossil fuels (coal, oil and natural gas) for energy. Burning fossil fuels releases carbon dioxide and other heat trapping gases, also known as greenhouse gases, into the atmosphere. This warming cannot be explained by natural causes (volcanic and solar) alone. It can be said with confidence that human activities are primarily responsible for the observed 1.5 ˚F increase in 20th century temperatures in the Pacific Northwest. A warmer climate will affect this state substantially. In 2007, the Oregon State Legislature charged the Oregon Climate Change Research Institute, via HB 3543, with assessing the state of climate change science including biological, physical and social science as it relates to Oregon and the likely effects of climate change on the state. This inaugural assessment report is meant to act as a compendium of the relevant research on climate change and its impacts on the state of Oregon. This report draws on a large body of work on climate change impacts in the western US from the Climate Impacts Group at the University of Washington and the California Climate Action Team. In this report, we also identify knowledge gaps, where we acknowledge the need for more research in certain areas. We hope this report will serve as a useful resource for decision-makers, stakeholders, researchers and all Oregonians. The following chapters address key sectors that fall within the biological, physical and social sciences in the state of Oregon.

Full text
Abstract:
The potential biogeochemical and ecological impacts of ocean alkalinity enhancement were tested in a 5-weeks mesocosm experiment conducted in the subtropical, oligotrophic waters off Gran Canaria in September/October 2021. In the nine mesocosms, each with a volume of about 10 m3 inhabiting a natural plankton community, alkalinity enhancement was achieved through addition of a mix of sodium bicarbonate and sodium carbonate, simulating CO2-equilibrated alkalinization in a gradient from control up to twice the natural alkalinity. The response of the enclosed plankton community to the alkalinity addition was monitored in over 50 parameters which were sampled or measured in situ daily or every second day. In addition to the mesocosm experiment, a series of side experiments were conducted, focusing on individual aspects of mineral dissolution, secondary precipitation and biological responses at the primary producer level. This campaign, in which 47 scientists from 6 nations participated, generated the most comprehensive data set collected so far on the ecological and biogeochemical impacts of ocean alkalinity enhancement.
