The document discusses the three major parts of the ocean: the continental shelf, continental slope, and ocean floor. The continental shelf is a shallow area near the coast that many fish and invertebrate species live in. The continental slope is a steep decline between the shelf and ocean floor characterized by cold temperatures and low light levels that slow the metabolisms of organisms there like rockfish and thornyheads. The ocean floor is the deepest part of the ocean where unusual life forms have adapted around hydrothermal vents.

Intertidal organisms and their zonation, M. Sc. Zoology, University of Mumbai
The document describes the zonation patterns found in the intertidal region. It notes that the intertidal region lies between the high and low tide marks and is divided into three main zones - upper, middle, and lower intertidal regions. Organisms are distributed into horizontal bands based on their ability to tolerate different durations of submergence and exposure, resulting in distinct zonation patterns, especially in the upper regions which face more extreme environmental fluctuations. The dominant organisms vary across the zones depending on factors like substrate type and position in the intertidal area.
benthic
The document describes several deep sea creatures that live in the benthic zone at the lowest level of bodies of water. It provides details about the giant isopod, oarfish, sperm whale, giant squid, hatchet fish, sixgill shark, firefly squid, viperfish, hagfish, nautilus, lanternfish, and barbeled dragonfish. It notes characteristics like their sizes, families, abilities to glow or see in the dark, and relationships to other species.

Lecture 6 Intertidal Zones
There are different types of intertidal zones including rocky shores, sandy beaches, and mangrove swamps. Each habitat presents unique challenges for organisms to adapt to, such as shifting sands or exposure to air and waves. The intertidal zone can be further divided into subzones from the spray zone to the lower intertidal zone. Organisms in each subzone have developed adaptations like thick shells or burrowing to survive in their particular environment and deal with changes from tides.
Unit 5 pt.2
The document describes different zones and areas of marine life based on water depth and conditions. It discusses the pelagic zone where animals swim or float freely throughout the water column, the benthic zone along the sea floor, and the abyssal zone characterized by extreme pressures and lack of sunlight. It also describes hydrothermal vents where hot water emerges from cracks in the ocean floor, supporting unique ecosystems.
Ocean habitats
Marine habitats can be classified based on where organisms live and how they move. Plankton live in the water column and cannot swim against currents. Nekton actively swim and move independently of currents. Benthos live on, in, or near the seabed. The intertidal zone is the area between tide marks that can include rocky cliffs, sandy beaches, or mudflats. Estuaries form a transition between river and ocean environments with brackish water. Tide pools are rocky pools filled with seawater that only exist at low tide. Coral reefs are structures made of calcium carbonate secreted by corals. Kelp forests are dense underwater areas of kelp that are productive ecosystems.
Oceanic pelagic zone biology biome project
The ocean pelagic zone consists of the open ocean beyond coastal regions. It is divided into four subzones based on depth: (1) the epipelagic zone near the surface where sunlight allows photosynthesis, (2) the mesopelagic zone where little sunlight penetrates, (3) the bathypelagic zone in complete darkness where organisms eat falling debris or prey on each other, and (4) the abyssopelagic zone with extreme darkness and pressure. Organisms in the pelagic zone have adapted to the varying light levels, temperatures, pressures, and food availability of the different subzones.
Benthic zone
The benthic zone is located at the bottom of the oceans and is very cold, dark, and high-pressure due to the lack of sunlight penetration. Organisms that live in the benthic zone have adaptations like bioluminescence to find food and fast swimming to evade predators in the difficult conditions without light and under high pressure.

Earth science 15.2
This document defines and describes different types of marine organisms and zones they inhabit. It explains that plankton passively drift with ocean currents, while nekton can swim independently. Phytoplankton and zooplankton are types of plankton, and benthos live on or in ocean bottoms. The document also outlines various zones defined by sunlight penetration, distance from shore, and depth.
Estuarine systems
The Estuarine System consists of deepwater tidal habitats and adjacent tidal wetlands that are usually semienclosed by land but have open, partly obstructed, or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Offshore areas with typical estuarine plants and animals, such as red mangroves (Rhizophora mangle) and eastern oysters (Crassostrea virginica), are also included in the Estuarine System.
Life In The Ocean
The document summarizes life in the oceans across three dimensions. It discusses how oceans cover most of the planet's surface and contain a diversity of environments. Upwellings of nutrient-rich water from the ocean depths fuel high productivity along western coasts. Primary production varies globally and is limited by factors like temperature, sunlight, salinity, and nutrient availability. Life in the oceans includes plankton throughout the water column, benthic organisms along the seafloor, and nekton capable of independent movement against currents.
Estuaries
Estuaries are bodies of water where freshwater rivers meet saltwater oceans, forming brackish water. They support rich ecosystems but are threatened by pollution and climate change. The Chesapeake Bay estuary is suffering from agricultural and industrial runoff, which is lowering oxygen levels and harming fish and crab populations. Rising sea levels and warmer water temperatures due to global warming are eroding wetlands and stressing native species in estuaries like Delaware Bay. Protecting these vital ecosystems is important for wildlife and coastal communities.
STRATIFICATION OF MARINE ECOSYSTEM
This document summarizes the stratification and zonation of marine ecosystems. It defines stratification as different water masses acting as barriers based on properties like temperature and salinity. The oceans are divided into horizontal zones based on factors like sunlight, depth, and distance from shore and vertical zones based on light penetration. The major horizontal zones discussed are the coastal, intertidal, euphotic, bathyal, abyssal, and deep sea zones. The major vertical zones are the photic and aphotic zones. Coral reefs are also summarized as highly biodiverse ecosystems in the coastal zone that rely on a symbiotic relationship between corals and algae.
Endangered marine animals
The document discusses several endangered marine animal species that have been threatened by human activity and environmental damage. Whales, dolphins, seals, turtles and fish species have been overhunted for consumption and other uses. Their habitats and ecosystems have also been degraded by pollution, including oil spills, acid rain, excess waste, chemicals, sediment, and thermal pollution from power plants. Overfishing and introducing foreign species have also disrupted trophic chains. Conservation efforts should focus on preventing further oil pollution by reusing oil, using less oil, and prohibiting drilling in sensitive habitats.

This document describes various habitats found in saltwater ecosystems. It discusses horizontal and vertical zonation patterns. Horizontally, coastal habitats near the shore are distinguished from open ocean habitats further from land. Coastal habitats include intertidal zones, sandy and rocky shores, mudflats, salt marshes, mangroves, estuaries, kelp forests, seagrass meadows, and coral reefs. Vertically, benthic habitats at the sea bottom are distinguished from pelagic habitats in the water column above. Benthic zones include the littoral, bathyal, abyssal, and hadal zones, while pelagic zones are the epipelagic, mesop
Oceanic pelagic zone biology biome project FINAL
The pelagic zone consists of the open ocean beyond coastal waters. It is divided into four subzones based on depth and light levels: (1) The epipelagic zone near the surface has enough light for photosynthesis. (2) The mesopelagic zone has limited light. (3) The bathypelagic zone is completely dark. (4) The abyssopelagic zone exists at the greatest depths. Organisms in each subzone have adapted to the unique conditions of their environment, such as light levels, pressure, oxygen levels and food sources. Phytoplankton and zooplankton are primary producers, while animals include birds, fish, marine mammals, and
Marine geology.pptx
Benthic organisms live on the sea floor and include animals like sea anemones, sponges, corals, sea stars, sea urchins, worms, bivalves and crabs. There is high diversity among benthic organisms, especially mollusks. However, plankton diversity in the water column is much lower, with far fewer pteropod snail species than benthic snails. Depth, food supply, salinity, temperature and oxygen levels all impact the distribution and types of benthic organisms that can survive on the sea floor. Benthic organisms leave behind traces of their activities through trails, tracks, burrows and bioturbation, which can provide clues about environmental
Marine fisheries
Almost all natural bodies of water bear fish life, the exceptions being very hot thermal ponds and extremely salt-alkaline lakes such as the Dead Sea and Great Salt Lake. The fishes belong to the most numerous and diversified group among vertebrates. They dominate the water bodies of the world through a variety of morphological, physiological and behavioral adaptations. They have been in existence for more than 450 million years. A total of 24618 species of fishes belonging to 482 families and 4258 genera have so far been described. About 58% of the fish species are marine while 41% are freshwater inhabitants and 1% migrants. In our Indian region alone, there are 2,500 species of which 930 are inhabitants of freshwater and the rest live in the seas. In other words, India harbours 11.5% of the fish fauna so far known in the world. There are over 800 living species of sharks and rays, 30 species of chimaeras and ratfishes, 6 species of lung fishes, 1 species of coelacanths, 36 species of long ray finned bichirs, sturgeons and paddlefishes. The Neopterygii are the rest of the known species of modem fishes. All these fishes inhabit various niches in the aquatic environment. The diversified habitats of fishes include open oceans, deep oceanic trenches, nearshore waters, saline coastal embayments, brackishwaters, estuaries, intermittent streams, tiny desert springs, vernal pools, cold mountain streams, lakes, ponds, etc.
Chapter 8 Oceanography
The document provides an overview of oceanography, including sections on the seafloor, life in the oceans, and ocean pollution. It describes various features of the seafloor such as the continental shelf, slope, and ridges. It also discusses different types of life in the oceans including plankton, nekton, benthos, and the processes of photosynthesis, chemosynthesis, and food chains.
Continental Shelf
The continental shelf is a shallow submerged region of continent that extends from the shoreline to the shelf break. It includes three zones - inner, mid, and outer continental shelf. Continental shelves were formed during glacial periods when sea levels dropped and exposed land that is now submerged. The average shelf is 80 km wide and 150 m deep, ending at the shelf break which marks the start of the steep continental slope. Continental shelves support rich ecosystems due to nutrients from land and ocean and most of the world's fish populations live along continental margins. They also provide resources like oil and minerals and are important for fisheries.
Marine ecosystem
Marine ecosystems cover over 70% of the Earth's surface and are home to a diverse range of organisms. They include nearshore habitats like salt marshes and coral reefs as well as open ocean areas. Marine animals include whales, dolphins, seals, octopuses, starfish, and many others. The marine food web begins with phytoplankton and algae which are eaten by herbivores and then carnivores, with top predators at the apex. Humans impact marine ecosystems through fishing, pollution, and climate change. International efforts aim to conserve and sustainably use ocean resources.
marine ecology
1. The ocean can be divided into horizontal and vertical zones based on depth and distance from land, with the epipelagic zone located at the top within 200 meters of the surface where sunlight and photosynthesis occur.
2. Below the epipelagic zone is the mesopelagic zone from 200-1000 meters where low light levels prevent photosynthesis, and many species have bioluminescence. The bathypelagic zone extends from 1000-4000 meters with no sunlight and low nutrients.
3. Marine organisms can be classified as plankton, nekton, or benthos depending on their lifestyle as floaters, swimmers, or bottom dwell
Unit iii chapter 15 (oceanography)
Oceanography is the study of the world's oceans using various scientific disciplines. There are four major oceans - the Atlantic, Pacific, Indian, and Arctic. The Pacific is the largest and deepest. Ocean water characteristics vary with depth, including temperature, salinity, and density. Ocean floor topography includes continental margins, mid-ocean ridges, ocean basins, and trenches. Sediments include terrigenous eroded from land, biogenous from marine life, and hydrogenous from seawater minerals. Reef types are atolls, fringing reefs, and barrier reefs which provide habitats based on light, distance from shore, and depth. Oceans are important for regulating climate, supporting economies, and providing biological
Ecology Chapter 25: AQUATIC ENVIRONMENT
The document discusses various aquatic ecosystems including lakes, rivers, estuaries, and oceans. It describes the key physical characteristics and biological adaptations that allow organisms to thrive in different aquatic environments. Lakes can be formed through geological or non-geological processes. Aquatic life is richest in shallow waters near shorelines. Rivers flow into seas forming estuaries with mixing of freshwater and saltwater. Oceans have vast benthic communities on the seafloor and unique hydrothermal vent and coral reef ecosystems. Primary productivity in aquatic environments is governed by light and nutrient availability.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Underwater Life
- 1. Underwater Life By: Megan Boham
- 2. There are 3 major parts of the ocean: Continental Shelf-is the outward extension of land from the continental landmasses, covered by relatively shallow water. Continental Slope-is the area between the offshore shallows out to where the continental shelf dips steeply to the sea floor. Ocean Floor-The ocean floor is the very bottom of an ocean basin
- 3. Continental Shelf Is a shallow submarine plain of varying width forming a border to a continent and typically ending in a comparatively steep slope to the deep ocean floor. Many species, from fishes to invertebrates, live on the surface of, or buried in, the soft sediments. These animals have adapted to the continuous shifting of sediments by ocean currents. Species that thrive in this environment include clams, sea pens, Dungeness crabs and flatfishes such as California halibut and English sole.
- 4. Continental Slope The deep waters of the Continental Slope are characterized by nearly freezing temperatures, extremely low light conditions, and very high pressures. Because of the cold, organisms that live at these depths have slower metabolisms—they eat less frequently, are slower in digesting their food, and move and grow more slowly. The most common fish in the Continental Slope are Rockfish and Thorny Heads.
- 5. Ocean Floor Is the lowest part of the ocean The ocean floor is home to a variety of plants and animals. Most of the deep ocean floor has few life forms, however around geothermal vents there is an abundance of sea life. Clams, spider crabs, mussels, and tube worms are just some of the animals scientists have discovered.
