Abstract of Investigation into saline ground water forStruan McDowall
Traditional farming has led to over 100 million hectares of saline land worldwide. This study tested whether inland saline groundwater could be used to produce live feeds like Artemia, rotifers, and copepods for aquaculture. The study found that while growth rates differed, the microalgae Nannochloropsis oculata and the rotifer Brachionus plicatilis grew better in inland saline groundwater than in natural seawater. The results suggest inland saline aquaculture could be a productive use of salt-affected land and benefit farmers.
The document discusses the issue of the Great Pacific Garbage Patch and its impacts on marine life and ecosystems. Through research, it has been found that large amounts of plastic pollution in the oceans are killing and injuring marine animals like turtles who often ingest plastic bags mistaking them for jellyfish. There is also evidence that the garbage accumulating on ocean floors is limiting food sources for smaller sea creatures and creating an imbalanced ecosystem. Further research is still needed to fully understand all of the impacts of deep sea garbage sitting on the ocean bottom.
The document discusses garbage islands, also known as the Great Pacific Garbage Patch, which is a massive area of marine debris trapped in the North Pacific Ocean by ocean currents. It contains high amounts of plastics, chemicals, and other trash, making it the largest landfill in the world. Around 10% of the plastic produced annually ends up in oceans, where it damages marine life and ecosystems. This plastic is eventually eaten by fish and smaller organisms, entering the human food chain and posing health risks. While efforts are underway to prevent further growth, fully cleaning up the patch is extremely challenging due to its vast size and remote location in international waters.
- The document discusses how the speaker's roots with the sea shaped their life path, leading them to study ocean acidification (OA) and its impacts.
- Their Watson Fellowship involved traveling to sites around the world to understand how OA may affect human communities dependent on ocean resources. They found OA could threaten industries like scallop fishing in Peru.
- The speaker learned that all communities have relationships with their environments and that problems often emerge from unhealthy relationships that enable unsustainable practices.
- Going forward, they see opportunities in fields that can help build healthier human-environment relationships and address issues like OA.
Marine debris comes from both land-based and ocean-based sources, with 80% originating on land. It has a variety of negative impacts on coastal ecosystems, such as entanglement, ingestion, and serving as a vector for toxic pollutants. Efforts to clean up marine debris include removing debris already in the oceans, installing filters on storm drains to intercept debris before it reaches waterways, and enacting laws and regulations to reduce future debris entering the environment.
The document discusses ecosystems, food chains, and water resources. It defines key terms like ecosystem, producers, consumers, and watershed. It explains how living things interact through food chains and how human activities can pollute water resources and disrupt ecosystems. Specifically, it notes that stormwater runoff is a major cause of nonpoint source pollution that upsets food chains and ecosystems. The document emphasizes the importance of conserving and managing natural resources like water.
This document summarizes a study on marine debris found on beaches. The study hypothesized that land-based debris would be more abundant on beaches than sea-based debris. Through surveys of sandy beaches along saltwater and freshwater shorelines, the study found that 98% of debris was from land-based sources, primarily plastic. The document discusses the environmental and economic impacts of marine debris, such as threats to wildlife, contaminated water, and decreased tourism. It calls for global action through increased research, education, and efforts by communities and individuals to help address the growing problem of marine debris.

This plain English fact sheet outlines the work done by the EPA in monitoring phytoplankton in Ireland's marine environment.
The EPA and the Marine Institute sample phytoplankton in estuaries and coastal waters around Ireland. They carry out sampling three times during the summer and once during winter. At each location, they take water samples just below the surface and above the seabed. They use the samples to assess how much phytoplankton is in the water and what species are present.
Phytoplankton are tiny, free-floating plants found suspended in the world’s oceans. Their name comes from Greek and means ‘plant drifter’. They are carried along by ocean currents and are usually found floating near the surface of the water. Like all plants they need sunlight to grow.
The main sources of nutrients around Ireland’s coast are discharges from wastewater treatment plants and run off from agricultural land. Phytoplankton in the estuaries and coastal waters around Ireland are monitored by the EnvironmentalProtection Agency (EPA) and the Marine Institute. They monitor phytoplankton to assess the quality (status) of our marine environment. They must do this as part of the requirements of the European Water Framework Directive.
This document discusses the key components of streams and rivers, including stream banks, main channels, floodplains, and riparian buffers. It describes pools and riffles as two types of ecosystems in rivers and streams, noting that riffles usually have more organisms living in them due to higher oxygen levels. The document defines macroinvertebrates as small organisms without backbones that can be seen without a microscope, and explains how they are used to measure the health of streams.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s marine environment.
Ecologically healthy marine waters are a valuable natural resource. They support a rich and diverse range of ecosystems, habitats and species, and they are also a source of food – from wild fisheries and aquaculture. They are also important for recreational activities and tourism.
Transitional and coastal waters are assessed under the European Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). Having coordinated frameworks for water quality for all the water bodies in Ireland, and across Europe, allows us to compare our results with other countries. It allows us to see what works to help us make sure all our water bodies achieve at least ‘good’ status, and no deterioration occurs.
Project ecosystem - FRESH WATER ECOSYSTEMRajanPillai16
An ecosystem is a biological community made up of interacting organisms and their physical environment. Freshwater ecosystems include lakes, ponds, rivers, streams, springs, bogs, and wetlands. Energy enters freshwater systems through photosynthesis and is transferred between organisms as they feed on each other, while decomposers cycle nutrients by breaking down dead matter.
Water pollution is a serious global problem. It has various causes like industrial waste, marine dumping, oil spills, and agricultural runoff. This contamination affects ecosystems, spreads disease, and impacts food safety and access to clean water. Innovative solutions are being developed like the Great Bubble Barrier which uses air bubbles to divert waste in rivers, ferrofluid that binds microplastics magnetically, and devices like the Seabin and Wasteshark that collect floating trash from ports and harbors.
This Plain English fact sheet outlines the work done by the EPA in monitoring aquatic plants in Irish lakes.
Aquatic plants are good at showing if the quality of the water is good or bad and play an important role in lake ecology by providing food and a habitat for many smaller plants, animals and birds.
They also:
• provide shelter for young fish
• help to improve the clarity of the water
• help stabilise lake shore banks
• reduce the amount of sediment being suspended in the water
The Environmental Protection Agency (EPA) monitors these aquatic plants at more than 10,000 sites in over 200 lakes once every three years.
This document discusses the challenges of environmental pollution and climate change, and proposes putting youth in charge as a solution. It summarizes the work done by the UMass Boston Nantucket Field Station and other field stations, including research on water quality, harmful algal blooms, fisheries, climate change impacts like rising seas and stronger storms. The document advocates for youth leadership on environmental data collection and policy changes to address issues like runoff, invasive species, and plastic pollution.
This document contains a biology exam question from 2015 about ecosystems and human impacts. It includes questions about grouping organisms in a coral reef ecosystem as biotic and abiotic components, constructing a food web, discussing consequences of no coral reefs and effects of human activities. The passage notes that human activities like coral mining, pollution and overfishing threaten coral reef ecosystems and have accelerated species extinction rates globally. If human impacts continue developing, it predicts living organisms in the ecosystem will die off, become extinct and disrupt the ecosystem balance.
The document discusses several key ways that human activities are negatively impacting the ocean, including overfishing, pollution, and acidification due to carbon dioxide absorption. It notes that oceans are crucial for regulating climate and providing food and recreation. The document also highlights some success stories of initiatives that have helped to restore fisheries, reduce pollution, and better protect marine environments and species. Overall, it emphasizes the importance of sustainable practices and management to protect the ocean for future generations.
Government studies show that storm water runoff from human activities like fertilized lawns contributes to up to 70% of pollution in streams and lakes. Rain gardens were first thought of in 1990 but mimic natural watersheds, using plants and soil to collect and filter rain water runoff from rooftops and paved areas before it enters local water systems. To build an effective rain garden, one should dig a depressional area near the source of runoff to capture water, in a spot that receives full sunlight, with capacity sized based on the runoff surface and native water-tolerant plants.
Waste water treatment involves a process to convert wastewater into effluent that can safely return to the water cycle with minimal environmental impact. Wastewater includes household or industrial waste as well as storm runoff, which picks up harmful substances. Proper treatment is important for fisheries, wildlife habitats, recreation, and public health by removing suspended solids and disease-causing bacteria. Primary treatment removes 60% of solids while secondary treatment removes over 90% through aerating and biological waste removal. The major goals of wastewater treatment are to remove solids and return clean water to the environment.
Innovation for a Sustainable Ocean: World Oceans Day Summit, 2020STEMi Makers Africa
Kolisa Yola Sinyanya is a PhD candidate at the University of Cape Town, South Africa. Her research focuses on phytoplankton in the Agulhas Current off South Africa, which absorbs more carbon than all the world's forests combined. She uses stable nitrogen isotopes and fluorescence activated cell sorting to study nitrogen uptake by different phytoplankton size classes. Her research will help understand the productivity and biogeochemical cycling in this region and the role phytoplankton play in the warming ocean. She hopes to continue innovating for a sustainable ocean through her research.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s lakes.

Fillgood provides environmentally friendly home and body products through a distribution model that takes plastics packaging out of the mix.
This document summarizes a presentation on modeling the transport of effluent from fish farms. It discusses using computational fluid dynamics to understand how tides, currents, stratification, bathymetry and other physical processes influence where waste from aquaculture pens will transport and concentrate. The presentation shows example simulations of how excluding certain processes, like Earth's rotation, can impact results. It emphasizes the need to account for all relevant physics to accurately predict pollutant distribution and concentrations over time. The implications are that effluent can transport far from sources and see high intermittency and variability, challenging regulatory efforts.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s rivers.
Ireland has more than 73,000 km of river channels. If placed end-to-end, they could encircle the Earth almost twice. Three-quarters of these channels are very small streams that typically flow into larger rivers.
Biological monitoring has been carried out in Irish rivers since 1971. The current national river monitoring programme covers more than 13,000 km of river channel.
The national monitoring programme is run by the EPA and focuses on the main river channels rather than the smaller streams. The programme includes more than 2,800 sites sampled for biology, with almost half of these being sampled for physical and chemical parameters.
The document discusses ecosystems and biodiversity. It describes the hierarchy of ecological levels from species to biomes. The main ecosystems on Earth are then listed and described. Abiotic and biotic factors that influence ecosystems are defined. The document also discusses trophic levels and energy transfer through food chains. Human impacts like pollution, climate change, and overuse of resources can disrupt nutrient cycles and harm biodiversity. Evolution occurs through natural selection and genetic variation as organisms adapt to environmental changes over many generations.
The main goal of this research paper was to address the specific environmental impacts of harmful cyanobacterial blooms, and to describe the potential causes of these events.

In tribute to the most inspiring man who i have encountered on planet so far, a wonderful friend and constant source of brilliant ideas and resources. We are so much poorer without his presence now he has passed away, yet so much richer for knowing him, from learning from him. Your work will live on in everything I do. Go well my friend.
This document discusses biomimicry and how nature can inspire more sustainable solutions. It begins by outlining the current environmental impacts of human activity and the biotic crisis facing the planet. It then examines key principles found in nature, such as how natural systems operate within Earth's limited resources. Several case studies are presented that illustrate how biomimicry has been applied to problems in various industries, including energy generation, surface coatings, healthcare, transportation, manufacturing, and construction. Overall, the document promotes consciously emulating nature's designs, processes, and ecosystems to develop more sustainable technologies and systems that respect environmental limits.
Normally we think of producing food or biomass with terraculture (growing in earth), but aquaculture (growing in water) can be many times more productive for the same surface area. Therefore knowing how Aquaculture works is important if we want to create super-productive systems.
In this class we explore the basic principles & various good examples of very productive aquaculture (& multifunctional) in different parts of the world.
Also we explore how we can start very small in order to add mini-aquaculture-systems which are very easy to install & maintain, in our surroundings.
The document discusses the biosphere and the threats facing it. It defines the biosphere as the regions of Earth inhabited by living organisms, and notes there are 5 major biomes - aquatic, desert, forest, grassland, and tundra - which are further divided. It explains how the biosphere acts as a life support system and provides goods for humans. The major threats to the biosphere are deforestation, pollution, and climate change. Sustainable management of the biosphere's resources is important but faces economic, social, and environmental tensions.
We need quickly salt water loving crops as an alternative in Africa, Middle East and Central Asia and all over since it’s a 33% global landmass issue when this economic desert greening model will be implemented globally. When this economic desert greening model will be implemented globally (or even only in the MENA region), the whole global economy will get a powerful decades long new cycle. The IMF will love it just for this reason.

The document discusses various causes of environmental pollution including water pollution from everyday activities, untreated sewage, and industrial waste. It also discusses issues with rubbish and waste management leading to further pollution. Some consequences of pollution and climate change mentioned are more frequent and intense climate disasters, water shortages due to pollution and population growth, ozone layer depletion causing health issues, and melting glaciers affecting water availability and raising ocean levels. The document encourages actions like stopping deforestation, reducing energy and water use, and proper waste disposal to help address these issues.
Water is the most abundant liquid on Earth, covering 70% of the planet. Only 3% is freshwater, with 2/3 locked in glaciers or unavailable for human use. Water scarcity occurs when there is insufficient water to meet daily requirements within an area. It is caused by factors like climate change, pollution, increased demand, and overuse. Water scarcity affects human societies, health, cultures, ecosystems, and causes habitat and wetland loss. Solutions include education, rainwater harvesting, advanced desalination technology, improved sewage systems, and drip irrigation.
Climate like any other physical phenomena it is dynamic and not static.
In every part of the world one year, one decade or one century is different than the other.
The change does not only have academic important but its effects in all the forms of life.
Plants, animals, human beings change with changes of climate.
In general, all living species thrive under definite and limit conditions and any great deviation from that will leads to destruction and death of the species.
Ecology: Scientific study of interactions between organisms and their environments which includes Biotic Factors: (Living organisms) , Abiotic Factors: (Nonliving physical and chemical conditions of an environment).
What are the levels of the Ecology?
Ecology has Five Levels.
Individual organism: Single organism in an environment
Populations: Group of individual organisms of same species living in the same area
Communities: All of the organisms that inhabit a particular area make up a community, like coral reef and other organisms live around in the reef
Ecosystems: An ecosystem includes both the biotic and abiotic factors of an area
Biosphere:
Sum of all of Earth's ecosystems, it is an envelope of air, land, and water supporting all living things on Earth. It consists of both the atmosphere and ocean.
Ecologists investigate global issues in the biosphere, including climate change and its effect on living things
The effects have been most dramatic at high latitudes, where multiple processes contribute to decreased surface reflectivity
Changes in temperature are causing species to shift their natural ranges; however, those are unable to move in line with changing temperatures are being put at risk.
Cool Australia Biodiveristy 7&8 Powerpoint PresentationCool Australia
Biodiversity refers to all the living organisms that make up the web of life on Earth. High levels of biodiversity are important for clean air, food, fresh water, clothing, energy, and medicine for humans. However, human activities like pollution, overconsumption, climate change, and habitat loss are threatening biodiversity and causing a mass extinction. Conservation efforts aim to protect threatened species and restore damaged ecosystems, but protecting biodiversity will require individual actions like reducing waste, planting native plants, and choosing sustainable options.
This document provides information about ecosystems and ecology. It defines ecology as the study of relationships between living things and their environment. An ecosystem is described as a system of living things that interact with each other and the physical world. Examples of different ecosystem types are provided, including terrestrial, aquatic, marine, and freshwater. Abiotic and biotic factors that influence ecosystems are defined. Food chains and webs are explained as the pathways of energy transfer between organisms in an ecosystem. The document stresses the importance of ecosystems remaining in balance.
This document discusses various types of water pollution. It begins by defining a water pollutant and noting that only 3% of water on Earth is freshwater. It then describes several common pollutants that can enter waterways such as acid mine drainage, agricultural and urban runoff, sewage, sediments, heat, heavy metals and oil. It focuses on sewage as a major pollutant, describing its health, economic and environmental impacts. It also discusses nutrient pollution from sources like fertilizers that can cause eutrophication and dead zones. Throughout it provides examples of how pollution can be prevented through various filtration and treatment methods.
This document discusses various types of water pollution. It notes that only 3% of water on Earth is freshwater and pollution decreases usable freshwater. Common pollutants include sewage, nutrients from fertilizers and manure, sediments, heat, heavy metals and more. Pollution can be from point sources like pipes or non-point sources like urban/agricultural runoff. Sewage and excess nutrients can cause eutrophication, lowering oxygen and harming ecosystems. Preventing pollution at sources and using wetlands/treatment can help address many issues.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
