Introduction
71% of the Earth’s surface is covered by ocean water.
The oceans contain 97% of the earth’s water.
All the oceans and seas are actually one continuous body of water.
Oceanography is the study of oceans and formally began with a British expedition in 1873-1876. The oceans play an important role by supplying water vapor for rain, connecting continents and islands, and providing minerals from the ocean floor. The deepest part of the ocean is the Mariana Trench, which is about 10,800 meters below sea level, deeper than Mount Everest is tall. The Earth's major oceans are the Pacific, Atlantic, Indian, Arctic, and Southern oceans. The Pacific Ocean is the largest and deepest ocean, occupying one third of the total ocean area.
The document summarizes the major oceans on Earth - the Pacific Ocean is the largest, covering about one-third of the planet's surface. The Atlantic Ocean covers one-quarter, while the Indian Ocean is the third largest, containing about one-eighth of the total ocean area. Together with the Southern Ocean surrounding Antarctica, these bodies of water make up the one global ocean that contains 97% of Earth's water.
The document summarizes the five major oceans of the world: the Pacific Ocean, the largest and deepest ocean located between Asia/Australia and North/South America; the Atlantic Ocean, the second largest located between Europe/Africa/North America; the Indian Ocean, the third largest located between Africa/Asia/Australia; the Arctic Ocean, the smallest located around the North Pole; and the Southern Ocean surrounding Antarctica. Each ocean is briefly described in terms of location, key waterways, climate patterns, ocean floor features, and surface/ice coverage.
The document discusses the five main oceans of the world: the Pacific, Atlantic, Indian, Arctic, and Southern Oceans. It provides key details about each ocean, including their sizes and locations. The Pacific Ocean is the largest and deepest ocean, covering one third of the Earth's surface. The Atlantic Ocean separates Europe and Africa from North and South America and influences the climate of eastern North America and Western Europe via the Gulf Stream. The Indian Ocean lies between Asia, Africa and Australia and is the warmest ocean. The Arctic Ocean surrounds the North Pole and is frozen for much of the year. The Southern Ocean surrounds Antarctica.

The Kerala backwaters are a network of brackish lagoons and lakes lying parallel to the Arabian Sea coast (known as the Malabar Coast) of Kerala state in southern India, as well as interconnected canals, rivers, and inlets, a labyrinthine system formed by more than 900 kilometres (560 mi) of waterways, and sometimes compared to American bayous.[3] The network includes five large lakes linked by canals, both man made and natural, fed by 38 rivers, and extending virtually half the length of Kerala state. The backwaters were formed by the action of waves and shore currents creating low barrier islands across the mouths of the many rivers flowing down from the Western Ghats range. In the midst of this landscape, there are a number of towns and cities, which serve as the starting and endpoints of backwater cruises.

Grade - 6 Geography Ch.6. continents and oceans
The surface of the earth is covered with huge landmasses, known as continents, and large water bodies, known as oceans.
While continents are part of lithosphere, oceans form the hydrosphere.
The document discusses several key topics related to oceans and ocean habitats:
- It describes the five major oceans (Atlantic, Pacific, Indian, Arctic, and Southern) and provides some key facts about their sizes and locations.
- It explains how warming climate can cause sea level rise through thermal expansion of oceans and melting of land ice.
- It discusses some threats facing ocean habitats like pollution, overfishing, and climate change and their impacts on coral reefs, seagrasses, and other important ecosystems.
This document provides information about the sea from a presentation by students in Italy. It describes the sea's colors, how the land and sea meet at the coast which can be low and sandy or high and rocky. It also discusses islands, harbors, waves produced by wind, tides that change sea depth, the four seas around Italy and some animals found in the sea like crabs, dolphins, and turtles. Examples are given of places visited on holidays at the sea, including Rabbit Island in Sicily where sea turtles lay eggs and islands in the Tyrrhenian and Mediterranean seas.
The document discusses the immense size of the oceans, which cover over 70% of the Earth's surface and have an average depth of over 12,000 feet. It describes the diversity of over 1 million known marine species that live in all ocean environments, from the surface to deep sea vents. The text also explains how ocean life depends on food chains and webs that originate from photosynthesis at the surface or chemosynthesis at deep sea vents. Seas are smaller parts of the ocean enclosed by land, while the five oceans range in size from the massive Pacific Ocean to the Arctic Ocean.
The document summarizes the 5 oceans of the world: 1) Pacific Ocean is the largest and deepest, located between Asia/Oceania, Americas, and bounded by the Arctic and Southern Oceans. 2) Atlantic Ocean is the second largest with important waterways like the Strait of Gibraltar. 3) Indian Ocean is the third largest located between Africa, Asia, Australia with waterways like the Strait of Malacca. 4) Arctic Ocean is the smallest located around the North Pole with seasonal passageways. 5) Southern Ocean surrounds Antarctica between the Pacific, Atlantic, and Indian Oceans with a narrow Drake Passage.
The Atlantic is relatively a narrow body of water. It exists between two parallel continental masses.
The Atlantic Ocean touches both the Europe and the Africa on its eastern side. It is bounded by North America and South America along its western region. The Atlantic has no definite northern or southern boundaries. It runs into the Arctic Ocean on the north, and the Antarctic Ocean on the south. Some geographers consider the Arctic Circle as its northern boundary, and the Antarctic Circle as its southern boundary. The ancient Romans named the Atlantic after the Atlas mountains. These mountains rose at the western end of the Mediterranean sea.
After attending this lesson, the learner should be able to comprehend about the geographic setting of the Pacific ocean, its dimension, associated water masses, morphological features of the ocean floor, very significant conditions of the ocean, sediments, marine life, marine pollution and other hazards. In addition the user should be able to understand, the importance of the Pacific in the context of global activities including the historical oceanographic explorations.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.

The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
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.
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.
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.

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.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
