Earth is a closed system with fixed resources and waste that cannot be disposed of. It consists of four main interacting subsystems: 1) the geosphere refers to the solid Earth composed of rocks and minerals, 2) the hydrosphere is the totality of Earth's water in all phases, 3) the atmosphere is a mixture of gases surrounding the planet, and 4) the biosphere includes all life forms on Earth. The 1991 eruption of Mount Pinatubo released sulfur dioxide into the atmosphere, temporarily lowering global temperatures by 0.5 degrees and devastating the surrounding region through lahars and silicosis.

Environmental Science - Biogeochemical Cycle
Biogeochemical cycles help explain how elements are recycled through ecosystems. The most common cycles include water, carbon, nitrogen, sulfur, and phosphorus. Biogeochemical cycles consist of chemical, geological, and biological processes that circulate elements between living organisms and their inorganic environment. They maintain the flow of energy and matter through ecosystems and allow for the transformation and storage of elements. Examples provided include the water cycle, carbon cycle, and nitrogen cycle.
Biogeochemical cycle
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated. The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle.
Biogeochemical cycle and impact of anthropogenic activity by shashi shekhar s...
Human activities have significantly impacted global biogeochemical cycles. The water cycle is altered through withdrawing large amounts of freshwater, clearing vegetation, polluting surface and underground water, and contributing to climate change. The phosphorus cycle is impacted by removing phosphate from the earth for fertilizer and reducing tropical forest cover. The sulfur cycle is affected by industries and the burning of fossil fuels which release sulfur dioxide. The nitrogen cycle is altered through farming practices that release nitrous oxide and nitrogen into the atmosphere, contaminating groundwater with nitrates, and deforestation.
Lithosphere
The lithosphere is the rigid outermost layer of Earth composed of the crust and upper mantle. It exists in two types - oceanic lithosphere associated with ocean crust, and continental lithosphere associated with continental crust.
Soil is a natural resource that takes thousands of years to form. It is made up of weathered rock particles, living organisms, and dead organic matter. Soil degradation occurs through construction, acidification, salinization, and pollution.
Soil erosion is the removal of the fertile topsoil layer by water and wind. It can be caused by deforestation and unsustainable farming practices. Methods to prevent soil erosion include increasing vegetation cover through practices like crop rotation, reforestation,
Oceans
The document discusses the impact of oceans on weather, biodiversity, and mankind. Oceans cover 71% of the Earth's surface and influence weather patterns through ocean currents and the hydrologic cycle. The currents help circulate air and impact climates on land. Oceans also serve as a large home for marine species and provide many marine plants crucial to mankind, as phytoplankton and algae absorb huge amounts of carbon dioxide helping to reduce climate change.
Lithosphere
The lithosphere is the solid shell of the planet Earth. That means the crust, plus the part of the upper mantle that behaves elastically on long timescales.

Physical Environment and BioGeoChemical Cycles
The document discusses the physical environment and biogeochemical cycles on Earth. It defines the physical environment as natural features like mountains, rivers, forests, and divides it into the atmosphere, land, water, and living things. It then explains that biogeochemical cycles involve chemical substances moving through both biological and physical parts of Earth. Some of the most important cycles mentioned are the water, carbon, nitrogen, oxygen, rock, sulfur, and phosphorus cycles. The document also notes that mercury and human-caused cycles like atrazine are now being more closely studied due to climate change and human impacts.
Biogeochemical cycle
The document describes several biogeochemical cycles, including the water cycle and the carbon cycle.
The water cycle involves evaporation, transpiration, condensation, precipitation, and runoff, through which water continuously circulates between the atmosphere and Earth.
The carbon cycle consists of photosynthesis, respiration, combustion, and decomposition, through which carbon dioxide and oxygen are exchanged between living things and the environment. Photosynthesis produces oxygen and sugars from carbon dioxide and water, while respiration and combustion release carbon dioxide.
Biogeochemical Cycle
The document discusses biogeochemical cycles, which describe how chemical elements move through biotic and abiotic components of ecosystems. It describes several important cycles, including the carbon, nitrogen, sulfur, and phosphorus cycles. The carbon and nitrogen cycles involve gaseous forms and are considered closed or perfect cycles. The sulfur and phosphorus cycles are sedimentary and imperfect, as elements are eventually deposited as sediments. Biogeochemical cycles sustain life by recycling essential elements and maintaining chemical balances in ecosystems.
Biogeochemical cycles
The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
Biogeochemical cycles lecturer
Biogeochemical cycle is a pathway by which a chemical substance moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth.

Biogeochemical cycles
Biogeochemical cycles describe the cycling of essential nutrients like carbon, oxygen, nitrogen, phosphorus, and sulfur between the biotic (living) and abiotic (non-living) components of ecosystems. Energy from the sun drives these cycles as nutrients are exchanged between organisms, water, air, soil, and rock. Humans have disrupted natural biogeochemical cycles through activities like burning fossil fuels, clearing vegetation, using fertilizers, and pollution, which has contributed to issues like climate change and algal blooms.
Soil erosion
This document discusses soil erosion as a major environmental problem in Portugal. It begins by defining soils and outlining the key factors in soil formation. It then describes the different soil types found in Portugal based on past and current classification systems. Maps show the lithology, soils, and land use capabilities across Portugal. Soil erosion processes are examined, distinguishing between wind and water erosion. Various types of water erosion are defined. The document then focuses on Mação, Portugal as a case study area, noting it is affected by forest fires and land changes. Overall, the document provides background on soils and outlines soil erosion as a significant issue in Portugal using the region of Mação to illustrate the problems.
Earth's Spheres
The document discusses Earth's spheres which include the atmosphere, hydrosphere, lithosphere, biosphere, cryosphere, and anthroposphere. It explains that the spheres are closely interconnected, with changes in one sphere often causing chain reactions and changes in other spheres. An example is provided of a forest fire destroying plants, which leads to erosion, increased soil in water, higher turbidity, and impacts on water plants and animals, demonstrating the interactions between spheres.
Water & CC in the Himalayas
The Himalayas feed ten major rivers in Asia and store large freshwater resources critical to over 1.3 billion people. However, the Himalayan ecosystem is under threat from factors like glacial melt, deforestation, and climate change. As glaciers recede and precipitation patterns shift, water resources will become more unpredictable, potentially reducing supplies and increasing risks of floods and droughts. This will severely impact livelihoods from the mountains to the river deltas. International cooperation will be needed to manage the shared water resources and build resilience to these changes across the Hindu Kush Himalayan region.

Climate change
Climate change is caused by human activity that releases heat-trapping greenhouse gases like carbon dioxide and methane. Greenhouse gas levels are the highest they've been in 800,000 years and global temperatures are rising twice as fast as 50 years ago. Effects of climate change include rising temperatures, sea levels and droughts/heat waves that can worsen wildfires. Reducing fossil fuel use and increasing renewable energy and sustainability can help mitigate and adapt to climate change to reduce health impacts.
Potential Impacts of Climate Change and Ocean Acidification for the Future of...
The document summarizes various impacts of climate change and ocean acidification on tropical marine ecosystems in Indonesia. It notes that oceans have absorbed over 1/3 of anthropogenic CO2 emissions, leading to ocean acidification, sea level rise, and warming temperatures that affect corals, fish, and other marine life. Studies from Bali show bleaching has killed 60% of corals at one reef and lower pH and higher temperatures reduce coral and algal growth. The document also discusses impacts to blue carbon ecosystems like mangroves and seagrasses, including coastal squeeze from rising seas, changes in hydrology and salinity, and thermal stress. Cumulative impacts are expected to reduce carbon capture and sequestration. Solutions

Planetary boundaries
There are 9 planetary boundaries related to climate change, ocean acidification, chemical pollution, nitrogen and phosphorus loading, freshwater withdrawals, land conversion, biodiversity loss, air pollution and ozone layer depletion. Exceeding these boundaries risks irreversible environmental changes. Currently, the boundaries for climate change and biosphere integrity related to biodiversity loss have already been exceeded due to human activities like burning fossil fuels, large scale agriculture and deforestation. Urgent global cooperation is needed to transition systems and policies to prioritize environmental sustainability over unlimited economic growth to avoid catastrophic consequences.
Planetary boundaries
The document discusses planetary boundaries, which are nine Earth system processes identified as being critical for human survival. Exceeding the proposed boundaries for these processes risks severe environmental change. The boundaries discussed include climate change, ocean acidification, biodiversity loss, land use change, freshwater use, and biogeochemical flows of nitrogen and phosphorus. Crossing the proposed quantitative boundaries for some of these processes, like climate change and land use, risks triggering abrupt environmental shifts. The document argues that human activity has become the dominant driver of environmental change and that exceeding planetary boundaries endangers Earth's life support systems.
Water 1
Water has several important chemical properties that influence life in the ocean. Temperature affects oxygen levels and influences seasonal changes. Salinity is determined by dissolved salts and affects density. Density causes buoyancy and influences water layering. pH is affected by dissolved carbon dioxide and influences organism physiology. Dissolved gases like oxygen and nitrogen enter the water through diffusion and are important for respiration and nutrient cycling. Light penetration depends on wavelength absorption and determines the photic zone where photosynthesis can occur. These numerous parameters are interrelated, so changes to one can impact others and disrupt the delicate balance of the marine environment.

Chapter 56
The document summarizes the major compartments that make up the global ecosystem, including oceans, freshwaters, atmosphere, and land. It describes the flows of energy and materials between these compartments through biogeochemical cycles like the carbon, nitrogen, and phosphorus cycles. Human activities are impacting these natural cycles and global climate through fossil fuel usage and increased greenhouse gases in the atmosphere.
Greenhouse effect, GHG, Global warming and climate change.ppt.pptx
The document discusses the greenhouse effect and greenhouse gases. It explains that the greenhouse effect is a natural process that makes Earth habitable by trapping infrared radiation in the atmosphere and warming the planet. However, increased levels of greenhouse gases like carbon dioxide from human activities like burning fossil fuels are enhancing the greenhouse effect and causing global warming. If no action is taken to reduce emissions, the impacts of climate change like rising sea levels, stronger storms, drought, and mass extinctions will intensify.
weathering of Rocks and minerals
This document summarizes key concepts related to weathering and soil formation processes. It describes how weathering breaks down rocks through physical and chemical processes, forming regolith. The main factors that influence soil formation are then outlined, including parent material, climate, topography, organisms/vegetation, and time. Specific weathering and soil forming processes are also defined, such as podzolization, laterization, and gleization. Key minerals and their weatherability are discussed. The role of various physical and chemical weathering agents such as water, wind, temperature changes are also summarized.
Biogeochemical cycles
The document discusses several biogeochemical cycles including the water, carbon, nitrogen, phosphorus, and sulfur cycles. It provides details on the reservoirs, assimilation, and release stages of each cycle. For example, it notes that the water cycle involves evaporation and precipitation moving water between oceans, air, groundwater, lakes, and glaciers. Plants absorb water from the ground and animals drink or eat plants, while transpiration and excretion release water back. The carbon cycle describes photosynthesis fixing carbon from the air and respiration releasing it, and the nitrogen cycle involves nitrogen fixation, nitrification, and denitrification moving nitrogen between air, soil, plants, and animals.

Ocn 623-2 Geochemical Reservoirs.pdf
The document discusses three key questions about the Earth's oceans and land. It explains that the Earth has two main elevation levels - continents on average 840m above sea level, and the ocean floor on average 3800m below. This creates dry land. The Earth also has plate tectonics which formed continents, unlike Venus which likely only had one elevation level due to lack of water and plate tectonics. The document also introduces concepts of geochemical reservoirs and mass balances, noting early attempts looked at reactants like igneous rocks versus products like sediments, but modern understanding looks at cycling among reservoirs over geologic time to understand the Earth system.

Climate change and aspects of earth system
The document discusses the Earth system and its interactions. It is comprised of five spheres: the atmosphere, hydrosphere, biosphere, geosphere, and cryosphere. Each sphere interacts with the others in complex ways. For example, the water cycle moves water between the atmosphere, hydrosphere, biosphere, and geosphere. The carbon cycle also exchanges carbon between these spheres, and human activities like burning fossil fuels have increased carbon dioxide levels and acidified oceans. Understanding the interactions within the Earth system is important for studying climate change.
14 natural resources...aniket
Natural resources provide vital benefits but must be carefully managed. Forests are home to many organisms and supply oxygen while also providing wood. Fossil fuels are highly valuable but also cause pollution and are being depleted. Solar and wind energy are renewable sources but their availability varies. Overall, natural resources are invaluable but fragile, requiring sustainable practices to balance human and environmental needs.
Nota sains t1 b9
The document summarizes key aspects of Earth science:
1) The Earth system consists of four main components - hydrosphere, atmosphere, biosphere, and geosphere.
2) The Earth has layers including the crust, mantle, and core. Rocks form through igneous, sedimentary, and metamorphic processes.
3) Endogenic and exogenic processes shape the Earth, including plate tectonics, volcanism, earthquakes, and weathering.
4) Geohazards result from these processes and include volcanoes, earthquakes, tsunamis, and landslides. Technology helps monitor and warn of geohazards.
natural resources
The document provides an overview of natural resources and the environment. It discusses how life exists where the lithosphere, hydrosphere, and atmosphere interact to form the biosphere. Natural resources include both biotic resources like plants and animals as well as abiotic resources like air, water, and soil. However, human population growth, urbanization, and industrialization have led to these resources being used unsustainably. The document then examines various natural resources in more depth, including the composition and layers of the atmosphere, the water and carbon cycles, nitrogen cycle, ozone layer, and the greenhouse effect.
earth system [Autosaved].ppt
The document defines a system as interconnected components interacting to form a unified whole. It then describes the main subsystems that make up Earth's system: the atmosphere, lithosphere, biosphere, and hydrosphere. It explains that there is a constant exchange of heat, moisture, and gases between the atmosphere and hydrosphere through the hydrologic cycle, and that the biosphere exchanges carbon and is an important part of the carbon cycle.
Chapter 11 13
This document discusses water as a finite resource and provides details about groundwater systems. It notes that water is a regionally renewable resource, but not always locally. Groundwater flows underground and is recharged very slowly over long timescales. Pumping groundwater lowers the water table and can cause issues like subsidence. The document also discusses soil resources and issues like erosion, as well as mineral resources and the global distribution and demand issues for certain minerals.
Sec 4 chapter 8 the biosphere -slideshare
The document summarizes key concepts about the biosphere, biochemical cycles, biomes, and aquatic biomes. It defines the biosphere as the layer of life around Earth that contains all living things. It describes major biochemical cycles like the carbon, nitrogen, and phosphorus cycles that are essential for life. It then explains the characteristics and examples of different terrestrial biomes like tropical forests, grasslands, and tundra as well as aquatic biomes like lakes, rivers, wetlands, oceans, and coral reefs. Throughout, it emphasizes the interconnectedness of living and nonliving components of ecosystems.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
