Humpback whales have been on the endangered species list since 1966. Climate change now poses the biggest threat as the warming of the Southern Ocean is altering the habitat and food supply for humpback whales. The whales travel south each summer to feed, but are now finding their destination dramatically changed with frontal zones moving further south, decreasing sea ice and krill populations, resulting in less available forage for the whales.

Coastal Signs
The document discusses four coastal habitats: mangrove forest tidal swamp, beach and fore dune coastal marine habitat, tidal creek estuarine substrate, and coastal hammock maritime forest. It describes the key plant and animal species found in each habitat and some of the environmental factors and threats that influence each ecosystem.
Polar bear report - Sean
Polar bears rely on sea ice to hunt seals. As Arctic temperatures rise, sea ice declines and melts earlier each year. This reduces polar bears' time to hunt, causing them to lose weight and reproductive ability. Some polar bear populations have declined by 20% already. If warming continues, scientists project 2/3 of polar bears could be gone by 2050. The melting Arctic sea ice also threatens polar bears' habitat and forces interactions with grizzly bears invading from the south.

The document summarizes the current state of coral bleaching on the Great Barrier Reef. It describes how coral bleaching occurs when algae are expelled from coral due to stressors like heat waves. This year, record high ocean temperatures caused the worst mass bleaching event on the Great Barrier Reef. 50% of corals died in northern areas. The bleaching is part of the impacts of human-caused climate change and rising ocean temperatures. The document ends by highlighting some organizations working to help protect the reef through sustainable practices and fundraising.

Global warming
This document discusses the regional impacts of global warming across various continents. Some key points include:
- In Europe, southern countries will experience extreme drought while northern areas enjoy more moderate climates. Heat waves and floods will cause damage to human life and economies. Agricultural production may rise due to higher CO2 levels.
- In Africa, droughts will devastate agriculture and reduce water levels in rivers and lakes. Coastal areas face threats from rising seas. Species loss is a major concern.
- Australia and Oceania will see changing ecosystems with drier conditions and more fires and cyclones. The Great Barrier Reef is threatened with higher temperatures. Low-lying Pacific islands are at risk from sea level rise.
Ursus maritimus
The polar bear is a large carnivorous mammal that inhabits Arctic regions. It has white fur, a stocky body, and can weigh up to 1500 pounds. Polar bears live in areas with sea ice along Canada, Denmark, Norway, and Russia. Their habitat and populations are threatened by climate change as warming temperatures melt sea ice. Loss of sea ice strands polar bears on land and impacts their ability to hunt. Overhunting also contributes to declining polar bear numbers. While efforts aim to better regulate hunting and reduce environmental threats, polar bears remain endangered with their long-term prospects uncertain as the climate crisis worsens Arctic conditions.

Deep sea threats
This document outlines several threats facing the deep ocean environment, including overfishing through practices like factory fishing and pirate fishing that deplete fish stocks. Pollution such as plastics poses a big threat to marine life. Mining and drilling activities that explore deep areas of the ocean floor for valuable resources can damage fragile deep-sea ecosystems. Whaling and unintended whale and dolphin catch also impact ocean populations, while global warming alters deep ocean environments by warming waters and pushing species to shift ranges.

Featured case studies include successfully restoring coastal marsh for waterbirds and for northern pike, using watershed-based GIS planning tools to prioritize restoration projects, and the reestablishment of the Cat Island Chain of islands in lower Green Bay. This presentation was given by Janet Smith, Chair of the Biota and Habitat Work Group of the Science and Technical Advisory Committee for the Lower Fox River/Green Bay Area of Concern, Retired U.S. Fish and Wildlife Service.
Coast
Coastal landforms such as beaches, bays, capes, and peninsulas are shaped by the erosion and deposition of sediments from waves and tides. Coastal environments support a wide variety of plant and animal life, including mangrove forests, coral reefs, and migratory bird populations. Human activities like fishing, trade, tourism and urban development have drawn large populations to coastal areas but have also threatened coastal ecosystems through pollution, climate change, and overexploitation of resources. Coastal regions face risks from natural hazards exacerbated by sea level rise.
Jeopardy
The Great Barrier Reef is located off the northeast coast of Australia in the Coral Sea. It can be seen from space and is made up of billions of tiny coral organisms. It contains over 400 types of corals and is home to many plant and animal species, though some are threatened by rising water temperatures, pollution, and coral-eating crown-of-thorns starfish.
Cheddar Caves (sergio buendía y vanessa)
Richard Gough discovered the Cheddar caves in England between 1827-1902, which were formerly underwater and home to fish, and were later used as mines before becoming a tourist attraction. The caves in Cheddar Gorge were formed over 1.2 million years by floods carving the landscape from limestone bedrock, and they now contain stalactites, stalagmites, and columns that grow very slowly through the precipitation of calcite. Precise temperatures and humidity in the caves also make them suitable for aging Cheddar cheese.
Presentation
The document summarizes 3 mysterious places around the world:
The Great Blue Hole in Belize is a large underwater sinkhole formed during the last ice age. It is a popular diving spot known for its crystal clear water and diverse marine life. Socotra Island in Yemen is home to unique and exotic plant life, with 30% found nowhere else due to its isolation. The Bermuda Triangle is an area in the Atlantic Ocean where numerous ships and planes have disappeared under mysterious circumstances, with explanations ranging from supernatural to natural causes like methane hydrates.
Great barrier reef
The Great Barrier Reef located off the coast of Australia is home to sea turtles and humpback whales that thrive in its warm waters and abundant vegetation and plankton. However, the reef is endangered by threats such as global warming, hurricanes, overfishing, and starfish that eat coral, making it important to preserve this natural wonder by prohibiting coral collection by tourists.
The Incredible Adventure of Chasing Fish Up the Coast of Maine
Ross Sanner explains the excitement and incredible adventure that thousands of fishermen enjoy every spring -- chasing fish up the coast of Maine.
Ayla gr8 barrier reef slide show
The Great Barrier Reef is the largest coral reef system in the world, stretching over 2900 kilometers along the northeast coast of Australia. It is home to many colorful fish species and unusual coral. However, the reef is under threat from rising ocean temperatures and acidification caused by increasing greenhouse gases. As the carbon dioxide dissolves in the ocean, it is changing the ocean chemistry and harming the coral polyps that reefs are made of. While some species may adapt, the changes may destroy current reefs and it will take thousands of years for new reefs to form elsewhere.
Newfoundland And Labrador
The document discusses Newfoundland and Labrador's deep cultural connection to cod fishing over 500 years. Cod stocks dramatically declined in the 1960s and a moratorium on cod fishing was implemented in 1992. After 15 years, cod populations still had not recovered. A former biologist is now experimentally farming cod in hopes of helping coastal communities. Early results show farmed cod have thicker, firmer, whiter fillets. As global seafood demand rises, aquaculture is predicted to supply over half the world's seafood by 2030.
Rapidly Melting glaciers
Glaciers are melting rapidly due to climate change, threatening water supplies. The Himalayas contain the largest store of glacial ice outside the poles and supply water to over 2 billion people. As glaciers melt, initial floods will be followed by water shortages. Regions heavily dependent on glacial meltwater for agriculture, like parts of South America, are particularly at risk. Wildlife is also threatened by habitat loss as glaciers recede. Water harvesting techniques are helping high-altitude communities adapt to less predictable water availability.
Coral reef powerpoint annie and morgan
The document discusses threats facing coral reefs from human activities such as global warming, pollution, overfishing, and tourism. It notes that 70% of corals are threatened or destroyed, coral reefs have high biodiversity similar to rainforests, and 75% of fish are overfished. Human waste from cruise ships and other threats endanger coral reefs. The document calls on readers to help protect coral reefs through conservation efforts in their local communities and beyond.

This document discusses different types of estuaries:
- Bar-built estuaries are formed by sandbars along coastlines that partially block water flow and mixing. Wind is the main factor mixing fresh and salt water. Examples include Florida, Netherlands, North Carolina, and Texas coasts.
- Coastal plain estuaries formed as sea levels rose after the last ice age. They tend to be shallow with sloping bottoms and contain various fish and crab species.
- Tectonic estuaries are formed by earth's crust movements that cause sinking. Most form along fault lines during earthquakes, like San Francisco Bay.
- Fjords are long, narrow inlets with steep cliffs carved by
Biodiversity I
Coral reefs are extremely important ecosystems that provide habitat for 25% of marine life despite covering less than 1% of the ocean. They act as biodiversity hotspots and supply genetic diversity to other ocean regions via currents. The Coral Triangle in particular has the highest concentration of marine biodiversity and its protection is critical. Coral reefs are formed of calcium skeletons secreted by polyp organisms and provide food and shoreline protection to coastal communities while also contributing to carbon and water quality regulation. However, they are at risk from pollution, climate change, and destructive fishing practices.

Coastal wetlands provide breeding grounds for various water birds, fish, and other wildlife and act as natural filters. They are located along coastlines and in states like Louisiana and California, harboring plant life like grasses and trees as well as animals including eagles, fish, and birds. Efforts are underway to preserve coastal wetlands by establishing them as national parks or reserves.

Dolphins mysteriously have run ashore in Cape Cod over the past 5 weeks; around 120 dolphins have died- the largest toll of a single species in the Northeast in at least 2 decades
Whales Still Threatened by Noise Pollution
Whales and other marine life are threatened by increasing noise pollution from shipping, mining, sonar, and seismic surveys used by the oil and gas industry. Noise pollution disrupts whales' communication and ability to hunt, and has caused mass strandings that have killed hundreds at once. Whales are an endangered species, with only around 500 North Atlantic right whales remaining, and face additional threats from climate change, whaling, and ships that accidentally kill them. Stronger protections are needed to prevent whales from disappearing due to human activities.
Humpback whalesdt
Humpback whales catch their food using a feeding method called bubble-net feeding, where they swim in a shrinking circle while blowing bubbles to herd schools of krill, anchovies, cod, sardines, mackerel, and capelin. Humpback whales face threats from human activities like pollution, illegal whaling, noise, fishing gear, ship collisions, and habitat degradation. Their habitat ranges along the coasts of the continental United States.
Owens Cayman
The humpback whale is a baleen whale that can weigh up to 130,000 pounds, measures 35 to 48 feet long, and eats plankton, crustaceans, and fish. It has long flippers and faces threats from killer whales, humans, and pollution.
Nabeu Antarctica
The humpback whale lives in Antarctica and feeds on krill, shrimp, and small organisms. They typically travel in groups of four or five. Humpback whales can grow up to 14 feet at birth and live in the waters near Antarctica where krill are abundant. Protecting Antarctica through reducing pollution and global warming will help the humpback whale habitat.
Baramins, Whales And Humans
This document discusses the concept of "baramins" or "created kinds" in young-earth creationist biology. It provides background on the development of baraminology as a field, which aims to identify groups of organisms that were created separately and can be considered distinct "kinds." The document outlines methods used in baraminology studies to determine continuity or discontinuity between groups, including morphological comparisons, fossil evidence, and evidence from hybridization. It also discusses perspectives on how baramins may relate to biological classifications like family and where baraminologists are publishing their work.

Humpback whales are large whales that live in oceans around the world. They can grow up to 50 feet long and weigh up to 2,500 pounds. They have brushes instead of teeth to help them eat small fish, shrimp, plankton, and krill. Humpback whales live in the blue oceans with many other animals and fish. They are known to jump out of the water, flip their tails, and breathe out tall sprays of water through their blowholes.
Facts About Humpback Whales

The amazing humpback whales
The humpback whale lives in the North Pacific Ocean and feeds on krill, plankton, and small fish. It uses bubbles to herd its prey and has a scientific name meaning "large-backed." Humpback whales were nearly hunted to extinction but are now protected, with conservation efforts including signs urging people not to pollute the ocean or harm marine life. Their endangerment stems from habitat loss, pollution, and past overhunting when they were mistaken as sea monsters.
Whales
This document is a presentation about whales that provides information over 10 chapters. It discusses where whales live in oceans around the world, what whales eat such as fish, seals and other whales, includes diagrams of whales and their internal anatomy, lists different types of whales, discusses predators of whales like sharks and humans, shares fun facts, and concludes with a video of a humpback whale.
Jorden report
Humpback whales face many threats including fishing nets and whaling. They have adapted to eat small fish like krill by having baleen plates and bristles to filter feed. Humpback whales migrate annually between warm breeding grounds and cooler feeding areas. Females give birth after a year-long gestation and calves stay with their mothers for over one year, learning survival skills.
David Fleetham, underwater photographs of life in the world's oceans
This document is a collection of underwater photographs taken by photographer David Fleetham across various locations including Hawaii, Mexico, Australia, Indonesia, Palau and Micronesia. The photographs feature various shark species like oceanic whitetip sharks, Galapagos sharks, great white sharks and reef sharks. Also included are images of whales, turtles, fish and other marine life. The photographs provide views of animal behaviors and close interactions between divers and photographed species.
Food webs & food chain
The document discusses food webs and food chains. It defines them as models that show feeding relationships between organisms in an ecosystem. A food web consists of multiple interconnected food chains, with producers like plants obtaining energy from the sun and consumers obtaining energy by eating other organisms. The document provides examples of herbivores, carnivores, and omnivores, and explains how energy passes from producers to different levels of consumers in a food chain.

Polar and maple
The document provides facts about polar bears including:
- Nearly 60% of polar bears live in Canada, using sea ice as a hunting platform.
- Sea ice is declining by 9% per decade due to climate change, threatening polar bears.
- Studies show less sea ice leads to less reproduction and weight loss for polar bears.
Arctic
The Arctic region lies within the Arctic Circle and includes parts of 8 countries. It has a very cold climate, with average January temperatures of -35°C. The indigenous Inuit people have lived in the area for over 9,000 years, traditionally hunting and fishing, but many now work in oil fields. The Arctic ice is melting rapidly due to climate change, with a loss of 14% of permanent sea ice from 2004-2005. As ice melts, it is replaced by darker water that absorbs more solar radiation, causing a feedback loop of more melting. By 2100, 50-60% of Arctic ice may be gone, and by 2700 it could all be melted. This endangers marine species and indigenous communities

Gray Whales of Point Reyes
Think a person needs a large boat and/or lots of money to see whales?
Not at all. Whale watching can be done from shore—if one knows where
to go. One of the best places to see whales from shore is Point reyes
National Seashore, an hour’s drive north of San Francisco, California. In
fact, studies have shown that 94 percent of the migrating gray whales
along the Pacific Coast swim within a mile of the park. So not only can
one see whales, one can do so without getting seasick. Southbound gray
whales begin to show up off Point reyes in late November, with their
numbers peaking around mid-January. The northbound migration peaks
in mid-March, with the cows and their calves passing through as late as
April and early May.
What’s Remarkable about Gray Whales?
The gray whale is one of the nine “great whales,” a group that includes the
largest animals ever to grace the planet (the blue whale is usually given
the title of largest). The gray whale, although about one-third the size of
the blue whale, still weighs an astonishing 70,000 pounds and can reach
45 feet in length (longer than a city bus). How do whales get so large? The
answer is genetics, long lives, and lots and lots of food. To acquire that
food, gray whales gulp in enormous quantities of water and bottom sedi-
ment and then filter out small crustaceans with their specialized comb-
like filters called baleen. Compared to other baleen whales that feed in the

suited for straining out the bottom-dwelling marine invertebrates it pre-

swimming sideways while stirring up sediments on the muddy sea floor.
It’s possible that this strange behavior, combined with the whale’s sensory
organs, helps them better find and consume food buried in the muck.
Whale Migration
Animals do not migrate just for the heck of it. There has to be a reason.
For the gray whale it comes down to the fact that the Arctic Ocean is rich
in food during the summer, but the warm waters of the equatorial Pacific
are a much better place to rear young and spend the winter. Hence, every
year the gray whale logs about 12,000 miles on this round-trip migration,
perhaps the longest migration of any mammal ...
Top 9 Endangered Atlantic Marine Mammals
The document summarizes information on 10 marine mammal species listed as threatened or endangered on the IUCN Red List.

The species included are: narwhal, beluga, sperm whale, West Indian manatee, hooded seal, fin whale, blue whale, sei whale, North Atlantic right whale.
Fishes-student's project of Sto. Tomas College-Danao
This document summarizes information on 10 extinct, 10 endangered, and 3 threatened fish species. Among the extinct fish are the Blackfin Cisco and Blue Walleye from the Great Lakes which were driven to extinction by overfishing and invasive species. Endangered fish discussed include the Atlantic Halibut, Beluga Sturgeon, and Acadian Redfish which face threats from overfishing, bycatch, and habitat loss. The document also profiles the Pelagic Thresher shark, Eulachon fish, and Canary Rockfish as threatened species.
Climate Change – A Threaten to Wildlife ppt
Climate Change – A Threaten to Wildlife. This ppt was presented by Vishnu K (me) at the oral presentation competition held by the Department of Zoology, NMS S. Vellaichamy Nadar College, Nagamalai, Madurai. I got the First Prize in that Competition. It is about Endangered Species and how the Climate change affects the Wildlife.
Isabella's Project
The document discusses various impacts that human activities and climate change have had on the Great Barrier Reef, including shipping accidents, oil spills, fishing, pollution, climate change, coral bleaching, and tourism. It notes that climate change, rising sea temperatures, and coral bleaching pose major threats to the reef's future. Fishing damages the ocean floor with nets and some areas are now off-limits, while pollution also harms the reef's survival.
Racing extension of fishes
This document discusses the extinction of several fish species from various bodies of water around the world. It describes how each fish species was driven to extinction through a combination of overfishing, habitat destruction, pollution, and the introduction of invasive species. Their extinction shows how fragile ecosystems can be impacted by human activities and that local extinctions may go unnoticed without proper study and management of fish populations. The diversity of ocean life is key to its long term survival but many species have already seen dramatic declines in their populations.
Top 9 endangered marine mammals in the Atlantic
The document discusses several marine mammal species that are threatened or endangered, including the narwhal, beluga whale, sperm whale, West Indian manatee, hooded seal, fin whale, blue whale, and sei whale. For each species, it provides information on population estimates, historical and current threats such as hunting or environmental impacts, and conservation status under CITES and other agreements.
Butterflies make better canaries activities docx
The document summarizes information about beluga whales, including their physical description, habitat, and causes of endangerment. Beluga whales have white skin and live in Arctic waters, traveling between open ocean in winter and shallow bays and estuaries in summer. Their populations have declined dramatically due to hunting and habitat alterations from activities like damming, dredging, and pollution. Conservation efforts aim to protect beluga whales by regulating hunting, altering shipping routes, reducing pollution, and tracking their populations to aid in recovery.

The Great Barrier Reef extends over 2,300 kilometers along Australia's northeast coast and is home to over 9,000 known species that live in a complex ecosystem dependent on the coral reef. It consists of around 3,000 individual coral reefs and was inscribed as a World Heritage Site in 1981 due to its unique natural attributes and scientific importance. Approximately 5 million tourists visit the Great Barrier Reef annually, contributing significantly to the Australian economy. However, the Great Barrier Reef is under threat from rising ocean temperatures, higher carbon dioxide levels, overfishing, and damage from tourism activities.

Antarctica by Chloe
Antarctica has no permanent human residents but is used for scientific research. Global warming is having serious effects on Antarctica such as melting ice shelves and decreasing populations of penguins and krill. The melting ice caps and rising sea levels caused by climate change in Antarctica threaten coastal lands and could lead to food shortages and natural disasters around the world.
Oseanografi
The document provides various facts about oceans and Antarctica:
- Sharks account for fewer than 10 human deaths annually while over 100 million sharks are killed each year for their fins. Polar bears have black skin and white fur that reflects visible light.
- Mauna Kea volcano in Hawaii is taller than Mount Everest if measured from its base on the ocean floor. The oceans cover most of the Earth's surface and contain nearly all its water.
- Each winter, Antarctica gains up to 20 million square km of sea ice, the largest seasonal phenomenon on Earth, which reflects heat and insulates the ocean. Various forms of sea ice develop as temperatures drop.

Glacier Melting
The document discusses the effects of melting glaciers across different regions of the world. It notes that glaciers are melting rapidly in the Arctic, North America, South America, Asia, and Africa. This is causing issues like freshwater shortages, reduced hydroelectric power production, decreased agricultural output, excessive flooding, and habitat loss for animals dependent on glaciers. Rising sea levels are also exacerbating risks for small island nations and coastal ecosystems like coral reefs. The Gangotri Glacier in particular is described as retreating at an average rate of over 27 meters per year between 1935-1990.
Polish team cosequences of melting
Global warming is causing glaciers to melt at increasing rates, which will have serious consequences. Rising sea levels threaten to flood coastal areas and create millions of climate refugees over the coming centuries. Additionally, melting glaciers will deplete freshwater sources for nearly a sixth of the world's population. To prevent further melting, nations must work to reduce carbon dioxide emissions from fuel combustion.

Whales
- 1. HUMPBACK WHALES: A VICTIM OF CLIMATE CHANGE by Lizzy Beato, Sam Clark-Clough, Ali Hentges, and Kristin Kerbavaz
- 2. Humpback whales have been on the endangered species list since 1966.
- 3. The biggest threat to the humpback whale population is no longer commercial whaling.
- 4. Now Humpback whales are being threatened by climate change
- 5. Humpback whales travel thousands of kilometers in the summer every year to the Southern Ocean to feed on krill and cephalopods, such as squid and cuttlefish.
- 6. Recently, however, when they finally reach their destination, they find it to be dramatically different from the Southern Ocean of earlier years.
- 7. In the past 50 years, the western Antarctic Peninsula has warmed at more than four times the average rate of world-wide climate change.
- 8. Frontal zones are predicted to move southward which means that humpback whales will have to travel 200 to 500 kilometers south to feed.
- 9. Area covered by sea ice is projected to decrease by 10-15%.
- 10. Loss of sea ice means a shift in species composition and less diatoms, which krill eat.
- 11. Less food for krill will result in less krill.
- 12. A loss of sea is will decrease whale foraging habitat and food supply.
