Abandoned mines from the 18th and 19th centuries continue to pollute waterways in Britain through discharged minewater. Iron pyrites exposed to oxygen and water during mining decomposes into iron oxides and sulphates, acidifying the water. This causes iron hydroxide precipitation that coats aquatic plants and organisms, reducing oxygen levels. The Coal Authority and Environment Agency work to treat minewater through passive, passive-pumped, and active schemes to prevent watercourse pollution. Monitoring at Clough Foot shows treatment improving water quality compared to untreated discharges.

Water Management
The document discusses various sources of river pollution including fertilizers from farming, warmer water and lower oxygen levels from power stations, and untreated domestic sewage. It also outlines how rivers are used for leisure, transport, industry, farming, and generating electricity. The Environmental Agency monitors water quality, promotes wildlife conservation, controls fishing, and manages water treatment to help regulate water management.
Ocean acidification
The document discusses the effects of increasing carbon dioxide levels in the atmosphere and oceans. It notes that the ocean absorbs one third of excess CO2 in the atmosphere, and that CO2 concentrations have risen from 280 to 387 parts per million currently and are projected to reach 450 to 550 ppm by volume. It also explains that the ocean is becoming more acidic as it absorbs more CO2, with the pH dropping by 0.1 currently and projected to decrease by 0.3 to 0.7 additional units by 2300, putting coral, clams, and plankton at risk.
World water day ppt
World Water Day is celebrated on March 22nd to promote awareness of the importance of fresh water. The document discusses water statistics such as how much of the Earth is covered in water and how little is available for human use. It also highlights water resources in Croatia like the Adriatic Sea and rivers, noting that Croatia has abundant, clean drinking water. The students wish each other a happy World Water Day.
Salinity notes
Salinity refers to the concentration of dissolved ions in water, measured in parts per thousand (‰). Average ocean salinity is 35‰ but it varies depending on evaporation, precipitation, and water sources. Salinity is higher in enclosed seas like the Red Sea (40‰) and Mediterranean Sea (38‰) due to limited freshwater input and high evaporation. It is lower in semi-enclosed seas connected to oceans by narrow straits, like the Black Sea (18‰) and Baltic Sea (8‰), which receive more freshwater from rivers. Temperature, pressure, and density can also impact ocean salinity.
Ocean Acidification and Ocean Noise
Ocean acidification is caused by higher levels of carbon dioxide in the atmosphere being absorbed by the ocean, which increases the acidity of ocean water over time. The pH of ocean water has dropped from around 8.2 to 8.1 and is projected to decrease by 0.3 to 0.4 units over the next century. As the pH of the ocean decreases, it absorbs more CO2 from the atmosphere. This interacts with water molecules to form carbonic acid, lowering pH further. Additionally, ocean acidification may amplify ocean noise levels by around 10% and extend the range of underwater sounds by about 500 kilometers. This can negatively impact marine species by disrupting communication, increasing stress levels, and potentially causing hearing

GEOLOGY & MINERAL RESOURCES OF SRILANKA
This document summarizes the different types of rocks found in Earth's crust and the mineral resources found in Sri Lanka. It discusses three main types of rocks - igneous, sedimentary, and metamorphic rocks - and how they are formed. It then describes some of Sri Lanka's important mineral resources, including gems, graphite, mineral sands, apatite deposits, and various limestone deposits. The majority of Sri Lanka's land is covered by Precambrian metamorphic rocks, with some sedimentary limestone found in the north. Gems, graphite, ilmenite, and apatite are among the key minerals currently being mined and many are important export commodities.
lime and its uses in engineering.
Quicklime, also known as burnt lime, is produced by heating limestone to high temperatures in a lime kiln, which decomposes it into calcium oxide. Hydrated lime is then produced by slaking the calcium oxide with water. Lime has many uses including in construction materials like mortar and plaster, water and sewage treatment, paper making, agriculture, pollution control, and forensics. The lime production process involves extracting limestone from quarries, selecting stones based on composition, calcining it in kilns fueled by gases or coal, and producing quicklime through the thermal decomposition of calcium carbonate in the limestone.
Limestone presentation by ruchika
Limestone is a sedimentary rock composed of the shells of dead sea creatures that built up over millions of years. It exists in various forms from soft chalk to hard limestone to the hardest marble. Limestone is mined through both open cast and underground mining. It has many chemical and industrial uses such as in cement, glass, paper, building materials, road construction, and more. Key processes in working with limestone include calcination to produce quicklime, hydration to produce hydrated lime, and reaction with carbon dioxide to produce precipitated calcium carbonate.
Limestone
Limestone is a sedimentary rock composed largely of calcium carbonate. It forms from skeletal fragments of marine organisms and makes up about 10% of all sedimentary rocks. Limestone erodes over thousands to millions of years through water and weak acids, forming caves and karst landscapes. It has many uses including building material, road base, fillers, and feedstock for other materials. Stalactites form on cave ceilings through dripping water depositing calcium carbonate over time.
NOAA marine protected areas
The document discusses marine protected areas (MPAs) in the United States as managed by NOAA. It notes that over 1,600 MPAs have been established, protecting around 41% of US marine waters. The national system of MPAs coordinates management of these areas across different jurisdictions. While MPAs limit some activities like fishing to protect resources, most allow multiple uses. MPAs are classified based on their focus, level of protection, and other characteristics to facilitate management and conservation planning. NOAA's National MPA Center works to develop and support the national system of MPAs through activities like maintaining an MPA inventory and enhancing stewardship.
Reef ecosystems and their decline
Reef ecosystems have been in steady balance for millions of years but are now in decline due to climate change, bleaching, and overfishing. Climate change is stressing corals through warmer water temperatures, which causes them to lose their symbiotic algae and turn white. The oceans absorbing carbon dioxide from human activities is also making the water more acidic, inhibiting corals' ability to build skeletons. Overfishing disrupts the delicate food chain by removing key species. To remedy this, stronger fishing regulations and more protected areas are needed, while addressing the underlying causes of climate change.
Coastal zone management
The document discusses coastal zone management and ecosystem-based management (EBM) of marine environments. It provides definitions and perspectives on EBM, including that EBM aims to maintain healthy ecosystems that provide services while accounting for human uses. It gives examples of EBM including a Puget Sound case study that models the food web and evaluates tradeoffs of seagrass restoration. Challenges to implementing EBM are fragmented governance and entrenched interests while more research is needed on historical data integration and evaluating EBM efforts.
Integrated coastal zone management
This document provides an overview of integrated coastal zone management and the relevant international, federal, and state players and legislation involved.

This document discusses how physical factors like sea level rise, sediment particle size, beach slope, and wave exposure affect benthic invertebrate assemblages in estuaries. It finds that the abundance, biomass, and oxygen consumption of intertidal macrofauna and meiofauna are significantly impacted by interactions among these physical factors. Specifically, mud flats have lower wave exposure and finer sediments leading to higher macrofauna biomass, while sandy shores have higher wave exposure and coarser sediments resulting in lower biomass. Sea level rise is expected to make estuaries less diverse and productive by reducing these metrics.

This document discusses invasive species in coastal ecosystems, focusing on Puerto Rico. It defines invasive species and describes common pathways like transportation and commerce. Invasive species threaten biodiversity and alter ecosystems. In Puerto Rico, lionfish, firefish, Asian tiger shrimp and sea lions have become established. Management challenges include inconsistent data and limited funding. Effective strategies prioritize high-risk species and pathways to prevent new introductions.
Mangrove ecosystems
Mangroves provide important ecological functions as transitional zones, nurseries, and carbon sinks. However, they face threats from human activities like deforestation, development, and climate change impacts such as rising sea levels and temperatures. Mangroves help protect coastlines and support fisheries but over 20% have been lost in recent decades. While rising CO2 and temperatures may enhance mangrove growth, the current rapid rate of change leaves less time for adaptation and migration with the loss of coastal areas to development. Management is needed to balance human uses of mangroves with conservation to maintain their critical ecosystem services.

This study aims to evaluate solid waste contamination from different land uses within the Río Piedras watershed in Puerto Rico and its impact on coastal zones. The methodology involves dividing the watershed into four transects of varying urban development and monitoring solid waste in residential and commercial areas. Plastics and metals will be quantified from each zone and their effects on water flow and coastal ecosystems assessed. Educational activities will be conducted in communities to increase awareness. The goal is to identify contamination sources and establish management strategies tailored to each community.
Seagrass Communities: The Anthropogenic Affects on Nursery and Habitat
This document provides an overview of seagrasses, their key characteristics, global and local distribution, functions, threats, and conservation efforts. Seagrasses are flowering plants that grow in marine environments, possess roots and leaves, and provide important ecosystem services like nutrient cycling, sediment stabilization, and nursery habitat. They are found globally in shallow coastal waters and support high biodiversity and productivity. However, seagrass coverage is declining due to threats like coastal development, boat damage, and worsening water quality. Conserving seagrasses is important for maintaining coastal ecosystems and fisheries.

This document provides an overview of seagrasses, their key characteristics, global and local distribution, functions, threats, and conservation efforts. Seagrasses are flowering plants that grow in marine environments, possess roots and leaves, and provide important ecosystem services like nutrient cycling, sediment stabilization, and nursery habitat. They are found globally in shallow coastal waters and support high biodiversity and productivity. However, seagrass coverage is declining due to threats like coastal development, boat damage, and worsening water quality. Conserving seagrasses is important for maintaining coastal ecosystems and fisheries.

This document outlines a research study that will measure the impact of Puerto Rico's 1993 Tourism Incentive Act on mangrove forest extension along the northern coast of Puerto Rico. The study will use remote sensing and GIS technologies to analyze changes in mangrove coverage before and after the Act's passage. Three study sites will be examined: Piñones, Vega Alta/Dorado, and Northeast Ecological Corridor in Luquillo. Analyzing mangrove coverage annually from 1983-2003 and in 2015 will allow the researchers to calculate rates of change and assess the effectiveness of mangrove conservation regulations. The study aims to provide objective evaluation of how incentive laws impact coastal resource management and suggest improved management strategies if needed
The effects of ocean warming ón marine physiology
This document discusses ocean warming and its effects on marine physiology. It defines ocean warming as the increase in ocean temperature due to greenhouse gas emissions trapping more heat. Scientists measure ocean warming using sensors on Argo floats that track temperature, salinity, and depth over time. Ocean warming reduces dissolved oxygen levels and affects marine species through hypercapnia, which is increased carbon dioxide in the blood. This stresses physiology and can impact reproduction. Long-term, ocean warming threatens marine biodiversity and ecosystem function.
Marine Ecology: Physical Limiting Factors
This document provides an overview of marine ecology, including basic concepts, marine habitats, lifestyles, and physical limiting factors. It describes the different zones in marine ecosystems like pelagic and benthic, and lifestyles like planktonic, nektonic, and benthic. It also examines various physical factors that limit marine life, such as light, temperature, salinity, nutrients, gases, depth/pressure, and geography. Finally, it discusses how human activities like pollution, development, and climate change are altering these limiting factors and affecting marine environments.
Carbon cycle in the ocean discussion
Evald Maceno is a graduate student at UPR writing an outline for a class on coastal environments. The document outlines carbon as an element and its physical and chemical properties. It describes carbon as part of a global cycle, moving between the atmosphere, biosphere, lithosphere, and hydrosphere. This carbon cycle is impacted by human activities like burning fossil fuels and deforestation, which increase CO2 levels and acidify the oceans. Rising ocean temperatures and acidification threaten marine life and food systems.
Discussion on sea level rise in Puerto Rico
Sea level rise due to climate change has negatively impacted Puerto Rico's coastal areas. Coastal erosion, loss of beaches and coastal habitats have affected tourism and livelihoods. Sea level rise also increases the risk of saltwater intrusion and mortality of coastal forests. Low-lying islands are particularly threatened by complete inundation with even modest levels of sea level rise. To mitigate these impacts, Puerto Rico needs to implement adaptation measures such as coastal defenses and zone planning. More work is still needed to prepare the island for future sea level rise at both short and long terms. Puerto Rico faces challenges similar to other Caribbean islands due to their low-lying coastal geography.
